McCoy Drilling & Completions uses three indicators to describe items of three degrees of importance.
A HAZARD to operators or equipment is represented by an exclamation point within a red triangle. identifies items of the
highest importance. Failure to heed information identified by a HAZARD symbol may result in bodily injury, death, cata-
strophic equipment damage, or any combination of these. A HAZARD may also indicate the potential for dangerous envi-
ronmental contamination.
A WARNING is represented by an exclamation point within an orange triangle, and contains information that will alert per-
sonnel to a potential safety hazard that is not life-threatening. A WARNING may also serve to alert the user to information
critical to the correct assembly or operation of the equipment in use.
A CAUTION is represented by an exclamation point within a yellow triangle and highlights information that may aid the user
during assembly or operation of your equipment. CAUTIONs are also used to ensure common errors are not made during
assembly or operation of your equipment.

A. SLING / LOAD BEARING DEVICE SAFETY
THE SUPPLIED LOAD-BEARING DEVICE (CHAIN SLING, RIGID SLING, SPREADER BAR ASSEM-
BLY, FRAME, OR ANY OTHER DEVICE THAT BEARS THE PARTIAL OR TOTAL WEIGHT OF THE
EQUIPMENT DESCRIBED IN THIS MANUAL) HAS BEEN SPECIFIED OR DESIGNED TO SUPPORT
THE EQUIPMENT DESCRIBED IN THIS DOCUMENT. FARR® WILL NOT GUARANTEE THE ABILITY
OF THE LOAD-BEARING DEVICE TO SUPPORT ANY OTHER PART, ASSEMBLY OR COMBINA-
TION OF PARTS AND ASSEMBLIES, OR ANY ADDITIONS TO THE EQUIPMENT DESCRIBED IN
THIS MANUAL THAT ADD WEIGHT TO THE EQUIPMENT, UNLESS SUPPLIED BY MCCOY.
MCCOY DRILLING & COMPLETIONS DOES NOT GUARANTEE THE INTEGRITY OF MODIFIED OR
DAMAGED LOAD-BEARING DEVICES, UNLESS THOSE MODIFICATIONS ARE PERFORMED BY
MCCOY.
McCoy Drilling & Completions recommends following an industry-accepted standard such as OSHA, ASME B30.9-2006, or manu-
facturer’s guidelines when performing any rigging and overhead lifting. Use by untrained persons is hazardous. Improper use will
result in serious injury or death. Do not exceed rated capacity. Slings will fail if damaged, abused, misused, overused, or improperly
maintained.
• Only grade 80 or grade 100 alloy chain should be used for overhead lifting applications.
• Working Load Limit (WLL) is the maximum allowable load in pounds which may be applied to the load-bearing device, when the
device is new or in “as new” condition, and when the load is uniformly and directly applied. The WLL must never be exceeded.
• Working Load Limit (WLL) is the maximum working load for a specific minimum sling angle, measured from the horizontal plane.
The Working Load Limit is identified on the sling.
• The Working Load Limit or Design factor may be affected by wear, misuse, overloading, corrosion, deformation, intentional al-
terations, sharp corner cutting action and other use conditions.
• Shock loading and extraordinary conditions must be taken into account when selecting alloy chain slings.
• See OSHA Regulation for Slings 1910.184, ANSI/ASME B30.9-”SLINGS”, ANSI/ASME B30.10-”HOOKS” and ANSI/AMSE
B30.26 “RIGGING HARDWARE” for additional information.
THE MINIMUM SLING ANGLE (THE ANGLE OF THE LEG OF THE SLING MEASURED

2. T = Proof Test, non-destructive examination; VN = non destructive examination and visual examination;
V = visual examination.
3. Dependant upon whether non-destructive examination has been carried out.
4. For the purposes of this standard, a substantial repair or modification is defined as any repair and/or
modification that has been carried out which may, in the opinion of the inspection body, affect the load-
bearing elements of the container or lifting device, or elements that contribute directly to its structural
integrity.
Written records of the most recent periodic inspection shall be maintained, and shall include the condition of the sling.
2. Proper Use Of Load-Bearing Devices
Whenever any load-bearing device is used, the following practices shall be observed.
• Load-bearing devices that are damaged or defective shall not be used.
• Slings shall not be shortened with knots or bolts or other makeshift devices.
• Sling legs shall not be kinked.
• Load-bearing devices shall not be loaded in excess of their rated capacities.
• Slings shall be securely attached to their load.
• Load-bearing devices shall be protected from snagging, and shall not be further obstructed by any object.
• Suspended loads shall be kept clear of all obstruction.
• All employees shall be kept clear of loads about to be lifted and of suspended loads.
• Hands or fingers shall not be placed between the sling and its load while the sling is being tightened around the load.
• Shock loading is prohibited.
• Do not stand directly under a load during lifting.
3. Storage Of Load-Bearing Devices
Proper storage of out-of-service load bearing devices is important to ensure full integrity of the device once it is returned to
service. Farr® recommends observing the following practices:
• Wipe off all excess grease. Use a solvent-based cleaner on rags to wipe all external surfaces to remove residual grease or
hydraulic fluid. Once the outside surfaces have been de-greased, wipe all external surfaces with clean water to remove re-
sidual solvent.
• Farr® recommends that an anti-corrosive agent such as Tectyl® 506 be applied to all external surfaces. Refer to manufacturer
data sheets for proper application and safety information. Allow the anti-corrosive coating ample time to dry - refer to manufac-
turer data sheets for drying times at room temperature.
• Store in a clean, dry location. When returning to service, note that a full inspection of the device must be performed.

i. Support the tong by the chain sling. Preset the positions of the side chains by rotating the turnbuckles on each side chain
hanger until the eye bolts are about half-way engaged in the turnbuckle. The turnbuckles can often be turned by hand;
if this is not the case, use an adjustable wrench across the flats on the turnbuckle to turn it. Rotating the turnbuckles in
one direction will cause the two eye bolts to extend away from the centre of the turnbuckle, while rotating them in the
other direction will cause the eye bolts to retract toward the centre of the turnbuckle. Place a level axially (side to side)
across the tong, ensuring that it is parallel with the surface of the tong. Rotate the turnbuckle on one or the other side of
the tong until the level indicates the tong is parallel - if there seems to be a large adjustment to make, split the adjustment
between the turnbuckles on each side chain.
YOUR EQUIPMENT HAS BEEN THOROUGHLY TESTED AND INSPECTED AT THE FACTORY.
HOWEVER, WE ADVISE INSPECTION AND TESTING OF YOUR NEW TONG AFTER TAKING
POSSESSION IN ORDER TO ELIMINATE THE POSSIBILITY OF SHIPPING DAMAGE.
McCoy Drilling & Completions recommends that the following pre-operating tests be performed after receipt from the factory or
after extended storage, prior to releasing the tong to operations:
• Perform a complete inspection of all fasteners to ensure none have loosened during transport.
• Connect the tong to the power unit, and apply full hydraulic pressure. Inspect and correct any leaks.
• Operate the tong at full speed and in high gear for a duration of one-half hour. Hot bearing caps may indicate impending
bearing failure.
• Switch to low gear and operate for an additional one-half hour at full speed.
• Run the backup through several clamp/un-clamp sequences to ensure functionality.
• Inspect all components and hydraulic fittings for possible defects following completion of the tests. All FARR Tongs have
been thoroughly tested at the factory prior to shipping, but shipping damage must be identified before running the tong
in an operational environment.
• Carefully inspect the safety door components, and test to ensure that the safety device on each door is operating cor-
rectly before releasing the tong to the operating environment.
TONG DOOR MUST BE CLOSED AND SECURELY LATCHED BEFORE THE POWER UNIT IS
STARTED IN ORDER TO ASSURE THE SAFETY OF OPERATING PERSONNEL
Ensure adequate lube oil and hydraulic oil levels before starting engine. Use start up procedures as recommended by the power
unit engine operator’s manual. Open the Bypass Valve on the hydraulic system, and inspect all pressure and return line hose
connections to ensure correct and secure installation.
Following inspection of the hoses, start the engine and allow it to idle until warm. Allow hydraulic fluid to circulate for approxi-
mately 10 minutes, then slowly close the Bypass Valve to allow hydraulic fluid to circulate through the hoses and to the tong
(circulating pressure should not exceed 200 psi). Place the tong gear shifter in low gear and rotate the tong slowly forward and
then reverse with the throttle valve control lever. Once this has been done and the proper size jaws have been installed, the
tong is then ready to run pipe.
3. Valve Operation
4-way proportional valves control operation of hydraulic devices on the tong assembly such as hydraulic motors and cylinders.
When any one valve is “centered” or in the detent position, there is no hydraulic output from the valve. When the valve is pushed
forward there is an effect, and when the valve is pulled back, there is an opposite effect. These valves feature proportional con-
trol, which means that further extension of the valve handle (thereby further opening the valve orifice) results in proportionally
higher hydraulic output to the controlled device.
The shifting shaft has three “detent” positions identifying the low speed/high torque position, the “neutral” or free-spinning
position, and the high speed/low torque position. The detent strength may be adjusted by releasing the locknut on the detent
tube and increasing or relaxing pressure on the detent spring. Ensure the locknut is tightened once the desired detent pressure
has been set.
To shift to the high-speed gear, move the shifting handle toward the rear of the tong, forcing the shifting shaft down. To shift to
the low-speed gear, move the shifting handle towards the front of the tong, forcing the shifting shaft up. Note that the high clutch
gear or the low clutch gear may not be exactly aligned when shifting, so the operator may need to “bump” the motor control
handle slightly to turn the main clutch gear shaft and shifting collar into alignment. This is most effective when applying a small
amount of pressure on the gear shift lever in the direction you want to shift the tong, ensuring the shifting collar will “catch” when
the main clutch gear aligns with either the high or low clutch gear.

THESE OPERATING PROCEDURES ASSUME THE USER HAS PROPERLY SET UP AND PRE-
PARED THE EQUIPMENT FOR OPERATION AS PER SECTIONS 2D, 2E, AND 2F OF THIS
MANUAL.
Set up and prepare your equipment for operation as per Section 2 of this manual Refer to the following sections:
• 2.D - Hydraulic Connections
• 2.E - Tong Jaw Installation
• 2.F.1 - Tong Rig-up and Leveling (Suspension)
• 2.F.2 - Tong Rig-up and Leveling (Leveling)
Your tong and backup assembly should be properly suspended, connected to a hydraulic power source, and ready to make or break
connections at this point.
1. Making A Connection
a) Ensure hydraulic power supply to the tong is energized. The master link on the rigid sling must be used to suspend the
tong. Do not suspend the tong from any other point.
b) Ensure the backing pin is in the “makeup” position. From the front of the tong, the backing pin correctly configured for
makeup will be in the 10 o’clock position (see Illustration 2.H.2 next page). If it is not, simply lift up and place in the cor-
rect position. The cage plate opening must be aligned with the door opening when setting the backing pin position.
RIG PERSONNEL MUST STABILIZE THE TONG AS IT IS LIFTED FROM THE DRILL FLOOR
SHIFTING TONG WHILE ROTATING THE MOTOR AND CAGE PLATE MAY RESULT IN
CATASTROPHIC GEAR TRAIN FAILURE
k) Push the motor control valve toward the tong to rotate the cage plate in the make-up direction.
p) Repeat steps “f” through “o” until the desired number of connections are made up.
a) Ensure hydraulic power supply to the tong and backup is energized. The master link on the rigid sling must be used to
suspend the tong. Do not suspend the tong from any other point. See Illustration 2.H.1.
b) Set the backing pin for “breakout” operation. Lift up on the backing pin and rotate it to the “breakout” position, which is 2
o’clock as seen from the front of the tong. The opening in the rotary gear must be aligned with the tong door opening in
order to properly set the backing pin (see Illustration 2.H.8).
c) Ensure the load cell and snub line are configured for break-out operation. The load cell must be transferred to the off-
driller’s side (the right hand side as seen from the rear of the tong), and the snub line must be transferred to the driller’s
side to perform break-out operations.
d) Open the tong doors (see Illustration 2.H.4).
e) Actuate the lift cylinder control valve to lift the assembly from the drill floor if necessary. Pushing the valve toward the center
of the tong will retract the lift cylinder to lift the assembly (see illustration 2.H.3). Note that rig personnel are required to
stabilize the tong and backup as it is being lifted so it does not swing and collide with other rig equipment.
RIG PERSONNEL MUST STABILIZE THE TONG AS IT IS LIFTED FROM THE DRILL FLOOR
f) Move the tong on to the tubing joint. Use the lift cylinder to ensure the tong jaws are at the correct location above the con-
nection joint.
g) Firmly close the tong door against the latch post.
h) Ensure tubing is roughly centered within the tong jaws - rig personnel are required to stabilize the tong above the connec-
tion until the jaws have been cammed on to the pipe or casing.
i) Breakout torque is only available when tong is in low gear. See Section 2.G.3 for instructions on shifting your tong to low
gear. Do not shift gears while the tong is rotating.
p) Use your rig’s standard pipe handling procedures to remove and rack the freed tubing stand.
q) Repeat steps “e” through “p” as many times as necessary to break out and un-thread the desired number of connections.
K. EXTREME COLD WEATHER OPERATION PROCEDURES
1) Consult the power unit engine operator’s manual for all cold weather operating procedures and precautions.
2) Select gear and bearing lubricants that are compatible with expected climatic conditions.
3) Select hydraulic fluid that is compatible with expected climatic conditions.
4) Allow hydraulic fluid to circulate for approximately 20 minutes after starting the power unit, prior to activating the bypass valve
to allow fluid to circulate to tong. If the power unit is equipped with an oil temperature gauge, ensure that the fluid has reached
operating temperature as specified by hydraulic fluid data sheet.
5) Allow for adequate drying of moisture (prior to lubricating) when cleaning tong parts in cold weather.
4. Pinion Idlers
Apply grease to the pinion idler bearing through the grease fitting recessed into the top of the half-shafts, located on the bottom
face of the tong (two locations total).
6. Clutch
Apply grease to the clutch bearings through the two grease fittings located on the clutch bearing cap on the bottom face of
the tong, and the single grease fitting recessed into the end of the clutch shaft. (three locations total). NOTE: A protective plug
may have been inserted into the end of the clutch shaft over the grease fitting prior to shipping - this plug may be removed for
normal operation.
8. Shifting Shaft
Apply grease to the shifting shaft and top shifting shaft bushing. The shaft and shifting yoke can be accessed through the cover
plate on the side of the tong.

NECTED TO ANY HYDRAULIC POWER SUPPLY. FARR RECOMMENDS THAT ALL HYDRAULIC
LINES ARE FULLY DISCONNECTED, AND RESIDUAL HYDRAULIC PRESSURE IS BLED OFF.
ENSURE ADEQUATE CONTAINMENT IS IN PLACE TO PREVENT ENVIRONMENTAL CONTAMI-
NATION FROM RESIDUAL HYDRAULIC FLUID.
Perform an initial wash of the tong in order to remove the majority of dirt and grease build-up. Ensure adequate contain-
3. ment is in place to prevent environmental contamination from residual hydraulic fluid and dirty grease.
4. Remove the access panel on the side of the tong directly adjacent to the shifter mechanism.
Use a flashlight to perform a visual inspection of the gear train through the access panel and the opening of the rotary
5. gear. If gear damage or chips of metal are seen, the tong should be removed from service and overhauled to avoid further
damage. Replace access panel when inspection is complete.
Perform a visual inspection of all fasteners and protruding body pieces (example: hydraulic valve mounts, inlet & outlet
6. line supports, tong legs, shifter handle pivot lugs). Tighten or replace loose or missing fasteners. Farr recommends that
damaged or missing body parts be repaired or replaced as soon as possible.
Inspect the jaws and dies. Inspect the jaw roller pins for signs of damage - replace pins if necessary. If the pins are welded
7. in place, replace the entire jaw assembly. Ensure dies are secure in the jaw - replace worn dies if necessary. Ensure that
the jaw rollers rotate freely. Check to ensure the size of the loaded jaws match the size of casing or pipe you are running.
Perform a visual inspection of all lifting points - if visible damage is seen, including cracks, broken lugs, distorted metal,
8. etc. replace damaged part(s) before placing tong in service. Also inspect all chains, master links, and turnbuckles - again,
if any damage is noted replace the damaged part(s) before placing the tong in service.
Inspect tong for signs of premature wear, or moving parts that are rubbing (bare metal where there used to be paint is a
9. good indication of wear.
10. Inspect backing pin(s). If cracked, broken, or bent it (they) must be replaced.
Inspect top and bottom brake band linings - replace if necessary. Unequal wear of the brake bands indicates that the
11. brake band tension is not evenly adjusted. Refer to the maintenance section of the manual for instructions on properly
adjusting brake bands.
Perform a visual inspection of all hydraulic lines. Replace flexible lines if they appear to be cracked, fatigued, or have
12. visible signs of wear from contact with a rigid object.

If using a stand-alone power unit, start it now - refer to the power unit technical manual for startup procedures. Listen to power unit for
a moment to see if there are any unusual mechanical sounds (rubbing, grinding, excessive pump noise). If using a diesel unit, allow
sufficient time for the engine to reach operating temperature before increasing engine RPM. Once engine is warm, gradually increase
engine RPM until operating speed is reached.
Ensure that supply pressure is at or above the tong’s specified operating pressure, and that the return pressure is less
16. than 350 psi.
17. Perform a visual inspection of pressurized hydraulic lines. Document and correct any hydraulic fluid leaks.
Perform a full functional test of the tong. Report and correct any hydraulic leaks from the hydraulic valve bank, or from
18. any hydraulic cylinders that are used.
Perform a visual inspection of the load cell. If using a tension load cell, replace any cracked, broken, or distorted com-
19. ponents including links and chains. If using a compression load cell, replace any component that has been crushed or
otherwise distorted through compression.
If applicable, inspect the load cell anchor pins (tension load cell only). Replace the anchor pins if cracking or metal
20. distortion is seen.
If applicable, the weld securing the single load cell anchor to the bridge bar main plate must be inspected (compression
load cell only). If the integrity of the weld has been compromised, the tong must be removed from service until the weld
21. is repaired. The load cell beam will need to be disconnected and removed so the weld is visible. Before re-installing the
beam, liberally grease the anchor pin before reinserting into the load cell beam.
Test safety door feature (if equipped). Open the tong door(s), and attempt to rotate the cage plate at low speed (low
gear) in both directions (makeup and breakout). If cage plate begins rotating, the safety door mechanism is not func-
22. tional, and the tong must be removed from service until the safety door mechanism can be repaired. If the safety door
is operating correctly, cage plate rotation will not be inhibited once the door is closed and latched.
While rotating the cage plate, ensure that the jaws properly cam. If the jaws do not cam properly, the brake bands
23. need to be tightened. Incrementally adjust both the top and bottom brake bands EQUALLY until proper cam action is
achieved (see section 3.E.1).
1. Rotate cage plate/rotary gear until the opening in the rotary gear faces towards the rear of the tong.

service. Prepare areas to be painted to ensure they are free of grease, dirt, or solvent. Touch up using a solvent-based
10. acrylic paint - “Farr Blue” is paint number RAL5005 (contact Farr sales for paint number for custom paint applications).
Allow sufficient time for paint to dry before proceeding.
Inspect all external welds. Any weld that is cracked or separating must be repaired and repainted before returning the
11. tong to service.
Rotate the gear train by hand, and use a flashlight to perform a visual inspection of the gear train through the access
panel and the opening of the rotary gear while the gear train is being rotated. If gear damage or chips of metal are
13. seen, the tong should be removed from service and overhauled to avoid further damage. Replace access panel when
inspection is complete.
Inspect all jaws and dies in use for the maintenance interval. Inspect the jaw roller pins for signs of damage - replace
14. pins if necessary. If the pins are welded in place, remove and quarantine the jaw until the weld is repaired. Ensure dies
are secure in the jaw - replace worn dies if necessary. Ensure that the jaw rollers rotate freely.
15. Inspect backing pin(s). If cracked, broken, or bent it (they) must be replaced.
Inspect top and bottom brake band linings - replace if necessary. Unequal wear of the brake bands indicates that the
16. brake band tension is not evenly adjusted. Refer to the maintenance section of the manual for instructions on properly
adjusting brake bands.
Inspect door springs. Ensure the springs retain sufficient strength to be able to assist the opening of the door, and to
17. keep the door open. The springs should also help to “snap” the door shut.
Inspect backup springs (if applicable). The rear extension springs should be equally extended, and the front leg springs
should be equally compressed. Ensure that neither of the rear backup springs have been over-extended and lack
18. sufficient tension to adequately support the backup. Ensure that neither of the front leg springs have been over-com-
pressed, and still retain enough spring strength to support the front of the backup.
Extend all hydraulic cylinders, and inspect cylinder rods for signs of mechanical damage, flaking, or rust. Farr recom-
19. mends that damaged cylinders be replaced prior to storage.
Perform a visual inspection of all hydraulic lines. Replace flexible lines if they appear to be cracked, fatigued, or have
20. visible signs of wear from contact with a rigid object. If your tong is equipped with rigid hydraulic lines, replace any line
that is dented or appears to be stressed or cracked.
Generously fill the gear train housing with grease through the access panel, and also through the opening in the rotary
21. gear. Perform a full lubrication - refer to Maintenance section of manual to determine lubrication points.
Ensure main supply and return connections to the tong are fully made up. Re-connect the remainder of the hydraulic
22. lines, and, if applicable, the electrical line to the turns counter.

Extend all hydraulic cylinders, and inspect cylinder rods for signs of mechanical damage, flaking, or rust. Farr recom-
16. mends that damaged cylinders be replaced prior to storage.
If you are using a frame-mounted tool, the tong must be lowered onto the backup in order to remove the risk of sudden
and catastrophic movement when pressure is removed from the float cylinders. Cover the top of the backup with protec-
tive cloth to protect the paint on the backup. Place two wooden beams across the top of the tong, ensuring that the beams
17. have a minimum size of 4” x 4” x the width of the tong. Cover the tops of the wooden beams with more protective cloth to
prevent paint damage to the tong. When lowering the tong onto the beams, ensure that the beams come into flat contact
with the bottom of the tong, away from bearing caps, brake bands, or other protrusions on the bottom of the tong. Ensure
that the tong hanger chains are loose, but not dangling into contact with the hangers or top plate of the tong.
18. If any hydraulic fittings or hoses are leaking they must be repaired or replaced before proceeding.
Wipe all excess grease from outside of equipment. Replace the access door panel. Use a solvent-based cleaner on
19. rags to wipe all external surfaces to remove residual grease or hydraulic fluid. Once the outside surfaces have been de-
greased, wipe all external surfaces with clean water to remove residual solvent.
Farr recommends that chain slings be removed and stored separately. Rigid slings and other rigid suspension devices
20. may remain in place.
Farr recommends that an anti-corrosive agent such as Tectyl® 506 be applied to all external surfaces EXCEPT cylinder
22. rods (including chain slings). Refer to manufacturer data sheets for proper application and safety information.

1. regular garbage.
2. Remove the access panel on the side of the tong directly adjacent to the shifter mechanism.
If applicable, re-connect chain sling to lifting lugs. Perform a visual inspection of all lifting points - if visible damage is seen,
including cracks, broken lugs, distorted metal, etc. replace damaged part(s) before placing tong in service. Also inspect
4. all chains, master links, and turnbuckles - again, if any damage is noted replace the damaged part(s) before placing the
tong in service. If your company requires yearly certification of lifting equipment, ensure that the most recent test date falls
within the past year. Perform recertification if necessary.
Perform a liberal lubrication of the equipment - refer to Maintenance section of manual to determine lubrication points.
5. Generously fill the gear train housing with grease through the access panel, and also through the opening in the rotary
gear.
Connect the equipment to a hydraulic power unit. Ensure all lines are fully made up to prevent equipment damage from
6. excessive back pressure. Do not neglect to connect the motor drain.
FAILURE TO ENSURE THAT THE SELF-SEALING SUPPLY AND RETURN LINES ARE FULLY
MADE UP MAY RESULT IN CATASTROPHIC EQUIPMENT FAILURE.
Ensure that supply pressure is at or above the tong’s specified operating pressure, and that the return pressure is less
8. than 350 psi.
Perform a thorough inspection of pressurized hydraulic lines and fittings. Any leaking hydraulic fluid lines or fittings must
9. be replaced before the equipment is returned to service.
Perform a thorough inspection of all seals. Any seal that is leaking or “weeping” must be replaced before the equipment
10. is returned to service.
Rotate tong in low gear for 5 minutes while monitoring pressurized seals and hydraulic lines. If a seal, line, or fitting begins
11. to leak while tong is rotating, it must be replaced before the equipment is returned to service. Finish this step with the
rotary gear opening facing the gear train. De-energize the power unit.
Inspect all flexible hydraulic lines for signs of wear, blistering, or any other signs of potential failure - replace if signs of
12. potential failure are identified.
Inspect the gear train housing. If the amount of grease is inadequate, liberally grease the gear train through the access
13. panel, and through the opening in the rotary gear.
Inspect top and bottom brake band linings - replace if necessary. Unequal wear of the brake bands indicates that the
brake band tension is not evenly adjusted. Refer to the maintenance section of the manual for instructions on properly
14. adjusting brake bands. Ensure that all grease is wiped from brake band linings and the parts of the cage plates that come
into contact with the brake band linings
15. Re-install access panel. Install a set of pre-inspected jaws that are the correct size for the pipe or casing being run.
Install load cell. If using a tension load cell, perform a visual inspection and replace any cracked, broken, or distorted
16. components including links and chains. If using a compression load cell, replace any component that has been crushed
or otherwise distorted through compression.
If applicable, inspect the load cell anchor pins (tension load cell only). Replace the anchor pins if cracking or metal distor-
17. tion is seen.
If applicable, the weld securing the single load cell anchor to the bridge bar main plate must be inspected (compression
load cell only). If the integrity of the weld has been compromised, the tong must be removed from service until the weld
18. is repaired. The load cell beam will need to be disconnected and removed so the weld is visible. Before re-installing the
beam, liberally grease the anchor pin before reinserting into the load cell beam.
While rotating the cage plate, ensure that the jaws properly cam. If the jaws do not cam properly, the brake bands need
23. to be tightened. Incrementally adjust both the top and bottom brake bands EQUALLY until proper cam action is achieved.
24. When all of the previous steps are completed, you may return your re-commissioned equipment to service.
4. POSSIBLE PROBLEM: Poor hydraulic pressure at the tong despite adequate pressure at the power unit, or excessive back
pressure in the return line.
SOLUTION: Restrictions exist in line between power unit and tong. Inspect integrity of self-sealing couplings to ensure they
are allowing full fluid flow. Check to ensure no other restrictions exist (contaminated catch screens or filters, for example).
5. POSSIBLE PROBLEM: Fluid viscosity is not appropriate (too high or too low).
SOLUTION: Ensure hydraulic fluid being used is the viscosity recommended by McCoy Drilling & Completions. Power unit pump
may not prime if fluid is too heavy, and the hydraulic system will overheat if fluid is too light. Replace with proper viscosity fluid.
SOLUTION: Hydraulic fluid viscosity is affected by environmental conditions. Ensure the fluid being used is suitable for high or
low temperatures. Replace with proper viscosity fluid for the operating conditions if necessary.
1. POSSIBLE PROBLEM: Dies have become too dull to provide adequate grip.
SOLUTION: Replace dies.
4. POSSIBLE PROBLEM: Brake band(s) is (are) insufficiently adjusted, not allowing jaws to cam properly.
SOLUTION: Adjust brake bands to give proper resistance to cage plates.
3. POSSIBLE PROBLEM: Tong motor is excessively worn and is leaking hydraulic fluid past the vanes.
SOLUTION: Replace motor, or rebuild as per Section 7 of this manual.
4. POSSIBLE PROBLEM: Bearings in gear train and rotary section are excessively worn.
SOLUTION: Overhaul tong. See Section 3 of this manual for tong overhaul procedures.
5. POSSIBLE PROBLEM: Shifter has malfunctioned and the tong is not shifting to high gear.
SOLUTION: Inspect and repair shift mechanism as necessary.
6. POSSIBLE PROBLEM: Two-speed hydraulic motor (if equipped) is not set to correct speed.
SOLUTION: Check motor, and set to the correct speed if required.
7. POSSIBLE PROBLEM: Safety door system is not properly adjusted - hydraulic fluid leak past Deltrol valve.
SOLUTION: Check and adjust safety door system.
5. POSSIBLE PROBLEM: Locking nuts on shifting shaft have loosened and position of yoke has changed.
SOLUTION: Reposition yoke and re-tighten locking nuts.
6. POSSIBLE PROBLEM: Shifting yoke has come loose from shifting shaft
SOLUTION: Inspect yoke and inspect for damage. If free of damage, replace on shaft and tighten locking nuts.

Product Description
These unbalanced poppet, logic valves are 2-way switching elements that are
spring-biased closed. Pressure at either work port 1 or 2 will further bias the
valve to the closed position while pressure at port 3 will tend to open it. The
force generated at port 3 must be greater than the sum of the forces acting at
port 1 and port 2 plus the spring force for the valve to open. NOTE: The pilot
area (port 3) is 1.8 times the area at port 1 and 2.25 times the area at port 2.
Technical Features
Because these valves are unbalanced, These valves are pressure responsive
operation is pressure dependent. at all three ports, therefore it is
