OPERATING INSTRUCTIONS
Oil Dipstick
STEP 1: Check engine oil level. Oil level should be level with the bottom of the oil filler neck. (Refer to the engine's
operating manual included with machine.) We recommend that the oil be changed after the first 5 hours of use,
then once every 50 hours. NOTE: Improper oil levels will cause low oil sensor to shut off engine. IMPORTANT!
Do not run engine with high or low oil levels as this will cause engine damage.

CLEANING TIPS
Pre-rinse cleaning surface with fresh water. Place detergent suction tube directly into cleaning solution and
apply to surface (for best results, limit your work area to
sections approximately 6 feet square and always apply
detergent from bottom to top). Allow detergent to remain
on surface 1-3 minutes. Do not allow detergent to dry
on surface. If surface appears to be drying, simply wet
down surface with fresh water. If needed, use brush to
remove stubborn dirt. Rinse from top to bottom in an
even sweeping motion keeping the spray nozzle approximately 1 foot from cleaning surface. Use overlapping strokes as you clean and rinse any surface. For
best surface cleaning action spray at a slight angle.
Recommendations:
Detergent Knob
RINSING
It will take a few seconds for the detergent to clear.
Apply safety latch to spray gun. Open detergent valve.
Select and install the desired high pressure nozzle.
NOTE: You can also stop detergent from flowing by
simply removing detergent siphon tube from bottle.

STORAGE
Measures should be taken to protect your FOCS series
engine if the engine is not operated for a period of 30
days or more. Proper storage will protect the engine
from corrosion and prevent costly repairs due to storage
induced problems.
Storage - 1 to 6 months
1. Start and idle the engine at a no-load condition for
15 minutes.
2. Stop the engine, allow the engine to cool enough
to safely drain the oil as shown Re-install the oil
drain plug, then fill the crankcase with MIL-L-644P9 protectant oil. Fill the fuel tank with a high grade
fuel preservative (add mix) such as STA-BIL per the
manufacturer recommendations.
3. Start and operate the engine at 3/4 speed for 5-10
minutes.
4. Stop the engine, allow to cool enough to safely
drain the engine oil as shown. Re-install the oil
drain plug.
5. Refill the engine with standard recommended lubricating oil.
6. Drain the fuel tank. Remove the fuel filter. Install a
new fuel filter.
7. Carefully clean all debris from the radiator fins.

MAINTENANCE
PREVENTATIVE
MAINTENANCE
1. Check to see that water pump is properly
lubricated.
2. Follow winterizing instructions to prevent freeze
damage to pump and coils.
3. Always neutralize and flush detergent from system
after use.
4. If water is known to have high mineral content, use
a water softener in your water system, or de-scale
as needed.
5. Do not allow acidic, caustic or abrasive fluids to be
pumped through system.
6. Always use high grade quality cleaning products.
7. Never run pump dry for extended periods of time.
8. Use clean fuel: kerosene, No. 1 fuel oil, or Clean
or replace fuel filter every 100 hours of operation.
Avoid water contaminated fuel as it will damage the
fuel pump.
9. If machine is operated with smoky or eye burning
exhaust, coils will soot up, not letting water reach
maximum operating temperature.
10. Never allow water to be sprayed on or near the
engine or burner assembly or any electrical component.
11. Periodically delime coils as per instructions.
12. Check to see that engine is properly lubricated.
It is advisable, periodically, to visually inspect the
burner. Check air inlet to make sure it is not clogged
or blocked. Wipe off any oil spills and keep equipment
clean and dry.
The flow of combustion and ventilating air to the burner
must not be blocked or obstructed in any manner.
The area around the washer should be kept clean
and free of combustible materials, gasoline and other
flammable vapors and liquids.
Winterizing Procedure:
Damage due to freezing is not covered by warranty. Adhere to the following cold weather procedures whenever
the washer must be stored or operated outdoors under
freezing conditions.
During winter months, when temperatures drop below
Pumps:
Use only SAE 30 weight non-detergent oil. Change oil
after first 50 hours of use. Thereafter, change oil every
three months or at 500 hour intervals. Oil level should be
checked through use of dipstick found on top of pump,
or the red dot visible through the oil gauge window. Oil
should be maintained at that level.
Cleaning of Coils:
In alkaline water areas, lime deposits can accumulate
rapidly inside the heating coil. This growth is increased
by the extreme heat build up in the coil. The best preventative for liming conditions is to use high quality
cleaning detergents. In areas where alkaline water is an
extreme problem, periodic use of Deliming Powder (Part
#112028) will remove lime and other deposits before
coil becomes plugged. (See Deliming instructions for
use of Deliming Powder.)
Deliming Coils:
Periodic flushing of coils or optional float tank is recommended.

MAINTENANCE
Burner Nozzle:
Keep the tip free of surface deposits by wiping it with a
clean, solvent saturated cloth, being careful not to plug
or enlarge the nozzle. For maximum efficiency, replace
the nozzle each season.
Air Adjustment:
Machines are preset and performance tested at the
factory. A one-time initial correction for your location
will pay off in economy, performance, and extended
service life. If a smoky or eye-burning exhaust is being
emitted from the stack, two things should be checked.
First, check the fuel to be certain that kerosene or No.
1 home heating fuel is being used. Next, check the air
adjustment on the burner.
To adjust: start machine and turn burner ON. Loosen
two locking screws found in the air shutter openings
(refer to illustration) and close air shutter until black
smoke appears from burner exhaust vent. Note air band
position. Next, slowly open the air shutter until white
smoke just starts to appear. Turn air shutter halfway
back to the black smoke position previously noted.
Tighten locking screws.
If the desired position cannot be obtained using only
the air shutter, lock the air shutter in as close a position

as can be obtained, then repeat the above procedure
on the air band setting.
Coil Removal:
Removal of coil because of freeze breakage, or to clean
soot from it can be done quickly and easily.
1. Disconnect hose from pump to inlet side of the
coil.
2. Carefully disconnect the thermostat sensor making
sure you do not crimp the capillary tube.
3. Remove burner assembly from combustion chamber.
4. Remove the 3-3/8" bolts from each side of coil and
tank assembly (these bolts are used to fasten tank
to chassis).
5. Remove fittings connected to the 1/2" pipe nipples
from inlet and discharge sides of coil.
6. Remove top tank wrap, bend back insulation tabs
and fold back blanket.
7. Remove bolts that hold down coil to bottom wrap.
8. Remove coil.
9. Replace or repair any insulation found to be torn
or broken.
1 0. Remove insulation retainer plates.
Coil Reinstallation:
Reinstall new or cleaned coil reversing Steps 9 through
1.
