Warning
1. Read and understand the entire owner’s manual before attempting assembly or operation.
2. Read and understand the warnings posted on the machine and in this manual. Failure to comply with all of
these warnings may cause serious injury.
3. Replace the warning labels if they become obscured or removed.
4. This chain hoist is designed and intended for use by properly trained and experienced personnel only. If
you are not familiar with the proper and safe operation of a chain hoist, do not use until proper training and
knowledge have been obtained.
5. Do not use this chain hoist for other than its intended use. If used for other purposes, JET disclaims any
real or implied warranty and holds itself harmless from any injury that may result from that use.
6. Do not install this chain hoist where explosive hazards may exist.
7. Give your work undivided attention. Looking around, carrying on a conversation and “horse-play” are
careless acts that can result in serious injury.
8. Do not use to lift people, or loads over people. Warn others in the vicinity when lifting or transporting a
load. Avoid swinging load and hook.
9. Do not exceed the rated capacity of the chain hoist.
10. Make sure limit switches are operating properly. Do not use limit switches as routine operating stops; they
are emergency devices only.
11. Do not use the load chain as a sling; this may cause damage to the chain.
12. Maintain firm footing when operating the hoist.
13. Always inspect the chain hoist for damage prior to use. Do not use a chain hoist with twisted, kinked, worn
or otherwise damaged chain. If the chain hoist is damaged, do not use until it has been repaired or
replaced.
14. Do not use more than one chain hoist to lift or move a load. If this is unavoidable, each chain hoist must
have the same capacity as the load to be moved.
15. Never allow the load chain to “set” over sharp edges. All lifts must be made with straight chain that is free
of obstacles.
16. Do not use a chain hoist unless load is centered between top and bottom hooks.
17. Protect load chain from weld splatter and other contaminants. Do not allow the hook or chain to be
contacted by a live welding electrode.
18. Always take time to study the job to be performed and choose the safest method. Do not place yourself or
other people in an unsafe position.
19. Leave all internal maintenance to a qualified JET service center.
20. Replace the chain with factory replacement chain only. Do not use any other type of chain.
21. Never use the chain hoist if either hook is stretched, deformed, or has a broken or missing safety latch.
Always replace the safety latch and/or the hook before placing the chain hoist back into service.
22. Do not operate this hoist while tired or under the influence of drugs, alcohol or any medication.
23. Understand and follow all procedures as set forth in American National Standards titled “Performance
Standard for Electric Chain Hoists.” ANSI/ASME HST-1. This standard is available through the American
Society of Mechanical Engineers, www.asme.org.
24. Do not use in wet, damp or poorly lit locations. This trolley is not rated for outdoor use.

Extension Cords
If an extension cord is necessary, make sure the
cord rating is suitable for the amperage listed on
the hoist's motor plate. An undersized cord will
cause a drop in line voltage resulting in loss of
power and overheating.

Adjustments
Safety Clutch Adjustment
The load limitation of the safety clutch has been set
to within 1.3 to 1.8 times the rated load of the hoist.
Generally, the safety clutch will not require
adjustment. But if the hoist ever fails to lift the rated
load while the rotor is turning, the safety clutch
must be re-adjusted. Proceed as follows (see
Figure 14):
1. Suspend the rated load in the bottom hook.
2. Push the UP button to create tension on the
load chain, but do not raise the load off the Figure 14
ground.
3. Disconnect the power source, and remove the
gear side cover.
4. Loosen the screw (G), open the plate (J), and
push down the adjusting shaft (K) until it fully
engages the adjusting circle nut (L). Rotate the
nut (H) clockwise to tighten the adjusting circle
nut (L).
5. Pull the adjusting shaft (K) out of engagement
with the adjusting circle nut (L). Then close the
plate (J) and tighten screw (G).
6. Connect hoist to power source, and push the
UP button on the pendant control. The hoist
should now lift the rated load. If it will not lift
the load, disconnect power and repeat steps 4
and 5 to tighten the adjusting circle nut until it
can lift the rated load.
7. Now change the load to within 1.3 to 1.8 times
the rated load, then push the UP button. The
hoist should NOT be able to lift the load. If it
can lift the load, repeat steps 4 and 5, rotate
the adjusting nut (H) and loosen adjusting
circle nut (L) until the hoist cannot lift the load.
8. Unload the hoist and repeat step 6 with the
original rated load. The hoist should now be
able to lift the original rated load. If it does not,
repeat steps 6 and 7 until the hoist operates
with the rated load only, but not with the 1.3 to
1.8 times rated load.
9. Unload the hoist, and re-install the gear side
cover.
13
Replacing Load Chain
Over time, the load chain will wear or elongate.
This can cause damage to the hoist, breakage, or
non-engagement of the load sheave. The following
procedures describe replacing the load chain for
single and multiple fall hoists. These procedures
should be performed by experienced personnel
only.

11. It is recommended that after installing new
chain, the first few lifts be limited to no more
than 25-50% of the rated load. Thoroughly
Inspect chain for twist before placing hoist in
routine service.
Vertical and Horizontal Links
Vertical and horizontal are determined by the
relationship with the load sprocket. Vertical links
will be guided by the center slit in the load
sprocket. Horizontal links will engage in the oval
pockets on the sprocket. See Figure 17.

1. Lower the load hook until only 1 to 2 feet of
slack chain remains in the chain container.
2. Remove chain container.
3. On the slack side of the chain, remove the
chain stop and the spring (Figure 16). Keep
these handy for later re-installing.
4. Using a C-link, connect the new chain to the
old chain. Be sure vertical link welds face
away from load sprocket (see Figure 17).
5. Keep tension on both sides of the chain and
lower the load hook to pull the new chain Figure 17
through the hoist. Do not let the chain twist or
bind as it is being pulled through the hoist.

Figure 18
Dual/Multiple Fall Chain Hoists
The link on the load side end

must be a vertical link. If it is a horizontal link,
the chain will have a twist in it.

Brake Adjustment
The normal gap between the armature and the iron
core is from 0.5mm to 1.0mm. If the gap is out of
the range of 0.5mm to 1.0mm, it must be adjusted
as follows (see Figure 20):
1. Disconnect hoist from power source.
2. Remove the gear side cover.
3. Remove the locking plate (H) by unscrewing
the four screws (J).
4. Insert a 0.5mm spacer between the iron core
(K) and the armature (B).
5. Tighten the four nuts (G) by an equal amount

one by one. The gap is now adjusted to
0.5mm.
6. Release the four nuts (G) by 1/6 of a turn and
remove the spacer. Re-tighten each of the
nuts by 1/6 of a turn.
7. Re-position the locking plate (H) and install the
four screws (J).
8. Re-install gear side cover.
NOTE: When adjusting the brake, if the brake pad
is found deformed, the glue has failed, or the lining
is severely worn, the brake pad should be
replaced. See page 19.

Inspection and Maintenance
All repairs and adjustments are to be performed by trained and experienced personnel
using procedures that are approved for the hoist system being serviced. All safety-related deficiencies
discovered in the inspection are to be corrected before hoist is placed back in service. Check for
internal damage whenever external damage has occurred.
Read and follow the ANSI Inspection and Maintenance instructions. Know the meaning of Frequent Inspection,
Periodic Inspection, Normal Service, Heavy Service, and Severe Service. It is the customer’s responsibility to
understand and follow all ANSI and JET inspection and maintenance instructions.
The following items are to be inspected by appointed personnel at the time interval noted below. Dated
inspection and repair reports must be maintained. Copies of all reports must be available to service personnel.
