THERMAL PUMP PROTECTION
If you run the engine on your pressure washer for 3-5
minutes without pressing the trigger on the spray gun,
circulating water in the pump can reach high temperatures. When the water reaches this temperature, the
pump protector engages and cools the pump by discharging the warm water onto the ground. This thermal
device prevents internal damage to the pump.

CLEANING TIPS
Pre-rinse cleaning surface with fresh water. Place detergent suction tube directly into cleaning solution and
apply to surface at low pressure (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 at
high pressure 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:

STEP 2: Use detergent designed
specifically for pressure washers.
Household detergents could damage the pump. Prepare detergent
solution as required by the manufacturer. Fill a container with pressure washer detergent. Place the
filter end of detergent suction hose
into the detergent container.
STEP 3: Apply safety latch to spray gun trigger. Turn
variable pressure control handle until discharge water
exits both tubes. Secure black detergent nozzle into
quick coupler if you have a single wand. NOTE: Detergent cannot be applied using Red, Yellow, Green or
White nozzles.

• Before cleaning any surface, an inconspicuous
area should be cleaned to test spray pattern and
distance for maximum cleaning results.
• If painted surfaces are peeling or chipping, use
extreme caution as pressure washer may remove
the loose paint from the surface.
• Keep the spray nozzle a safe distance from the
surface you plan to clean. High pressure wash a
small area, then check the surface for damage. If
no damage is found, continue to pressure washing.
CAUTION - Never use:
• Bleach, chlorine products and other corrosive
chemicals
• Liquids containing solvents (i.e., paint thinners,
gasoline, oils)
• Tri-sodium phosphate products
• Ammonia products
• Acid-based products
These chemicals will harm the machine and will damage the surface being cleaned.

STORAGE
CAUTION: Always store your pressure washer in a
location where the temperature will not fall below
32°F (0°C). The pump in this machine is susceptible
to permanent damage if frozen. FREEZE DAMAGE
IS NOT COVERED BY WARRANTY.
1. Stop the pressure washer, squeeze spray gun trigger to release pressure.
2. Detach water supply hose and high pressure hose.
3. Turn on the machine for a few seconds, until remaining water exits. Turn engine off immediately.
4. Drain the gas and oil from the engine.
5. Do not allow high pressure hose to become kinked.
6. Store the machine and accessories in a room which
does not reach freezing temperatures.
CAUTION: Failure to follow the above directions will
result in damage to your pressure washer.
When the pressure washer is not being operated or is
being stored for more than one month, follow these
instructions:
1. Replenish engine oil to upper level.
2. Drain gasoline from fuel tank, fuel line, fuel valve
and carburetor.
3. Pour about one teaspoon of engine oil through
the spark plug hole, pull the starter grip several

times and replace the plug. Then pull the starter
grip slowly until you feel increased pressure which
indicates the piston is on its compression stroke and
leave it in that position. This closes both the intake
and exhaust valves to prevent rusting of cylinder.
4. Cover the pressure washer and store in a clean, dry
place that is well ventilated away from open flame
or sparks. NOTE: The use of a fuel additive, such as
STA-BIL®, or an equivalent, will minimize the formulation of fuel deposits during shortage. Such additives
may be added to the gasoline in the fuel tank of the
engine, or to the gasolinee in a storage container.

After Extended Storage
CAUTION: Prior to restarting, thaw out any
possible ice from pressure washer hoses,
spray gun or wand.

Engine Maintenance
During the winter months, rare atmosheric conditions
may develop which will cause an icing condition in the
carburetor. If this develops, the engine may run rough,
lose power and may stall. This temporary condition can
be overcome by deflecting some of the hot air from the
engine over the carburetor area. NOTE: Refer to the
engine manufacturer's manual for service and mainte11
nance of the engine.

the washer must be stored or operated outdoors under
freezing conditions.

PREVENTATIVE
MAINTENANCE
1. Check to see that the water pump is properly lubricated.
2. Follow Winterizing Procedures to prevent freeze
damage to the pump and coils.
3. Always neutralize and flush detergent from system
after use.
4. If water is known to be high in 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 our 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 diesel.
Replace fuel filter every 100 hours of operation.
Avoid water contaminated fuel as it will seize up
the fuel pump.
9. If machine is operated with smoking or eye burning
exhaust, coils will soot up, not letting water reach
maximum operating temperature. (See section on
Air Adjustments.)
10. Never allow water to be sprayed on or near 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 this equipment clean
and dry.
The areas around the pressure washer should be kept
clean and free of combustible materials, gasoline and
other flammable vapors and liquids.
The flow of combustion and ventilating air to the burner
must not be blocked or obstructed in any manner. Consult factory if vent stacking is going to be used.

MAINTENANCE AND SERVICE
Unloader Valves:
Unloader valves are preset and tested at the factory
before shipping. Occasional adjustment of the unloader
may be necessary to maintain correct pressure. Call
your local dealer for assistance.

Winterizing Procedure:
Damage due to freezing is not covered by warranty. Adhere to the following cold weather procedures whenever
12

During winter months, when temperatures drop below
32°F, protecting your machine against freezing is necessary. Store the machine in a heated room. If this is not
possible then mix a 50/50 solution of anti-freeze/water
into a 5 gallon bucket. Place a short section of garden
hose into the bucket and connect it to the machine.
Elevate the bucket and turn the pump on to siphon the
anti-freeze through the machine. If compressed air is
available, an air fitting can be screwed into the inlet
connector and, by injecting compressed air, all water
will be blown out of the system.

High Limit Hot Water Thermostat:
For safety, each machine is equipped with a high limit
control switch. In the event that the temperature of the
water should exceed its operating temperature, the
high limit control will turn the burner off until the water
cools.

Pumps:
Use only SAE 30W non-detergent oil. Change oil after
the first 50 hours of use. Thereafter, change the oil every
three months or at 500 hour intervals. Oil level should be
checked by using the dipstick found on top of the 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 coil pipes. This growth is increased by
the extreme heat build up in the coil. The best prevention
for liming conditions is to use high quality cleaning detergents. In areas where alkaline water is an extreme
problem, periodic use of our Deliming Powder (part
#9-028008) will remove lime and other deposits before
coil becomes plugged. (See Deliming Instructions for
use of Deliming Powder.)

Deliming Coils:
Periodic flushing of coils is recommended.
1. Fill a container or optional float tank with 4 gallons
of water, then add 1 lb. of deliming powder. Mix
thoroughly.
2. Remove wand assembly from spray gun and put
spray gun into container. Secure the trigger on the
spray gun into the open position.
3. Attach a short section (3-5 ft.) of garden hose to
machine to siphon solution from an elevated container. Turn pump switch on, allowing solution to
be pumped through coils back into the container.
Solution should be allowed to circulate 2-4 hours.
4. After circulating solution flush entire system with
fresh water. Reinstall wand assembly to spray gun.

97-6132, 97-6151 • REV. 11/04

Rupture Disk:

Burner Nozzle:

If pressure from pump or thermal expansion should
exceed safe limits, the rupture disk will burst allowing high pressure to be discharged through hose to
ground. When disk ruptures it will need to be replaced.
The replacement rupture disk should be torqued to 35
ft. lbs.

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.

Fuel:

Use No. 1 or No. 2 Heating Oil (ASTM D306) only.
NEVER use gasoline in your burner tank. Gasoline is
more combustible than fuel oil and a serious explosion could result. NEVER use crankcase or waste oil
in your burner. Fuel unit malfunction could result from
contamination.

Fuel Control System:
These machines utilize a fuel solenoid valve located
on the fuel pump to control the flow of fuel to the combustion chamber. This solenoid valve, which is normally
closed, is activated by a flow switch when water is flowing through it. When an operator releases the trigger on
the spray gun, the flow of water through the flow switch
stops, turning off the current to the fuel solenoid. The
solenoid then closes, shutting off the supply of fuel to
the combustion chamber. Controlling the flow of fuel in
this way allows for an instantaneous burn or no burn
situation, thereby eliminating high and low water temperatures, and combustion smoke normally associated
with machines incorporating a spray gun.
CAUTION: Periodic inspection is recommended to insure that the fuel solenoid valve functions properly. This
can be done by operating the machine and checking to
see that when the trigger on the spray gun is in the off
position, the burner is not firing.

Machines are preset and performance tested at the
factory - elevation 100 feet. A one-time initial correction
for your location will pay off in economy, performance
and extended service life. If a smoking 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 below) 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.

OPERATOR’S MANUAL

Use clean fuel oil that is not contaminated with water
and debris. Replace fuel filter and drain tank every 100
hours of operation.

Fuel Pressure Adjustment:

Coil Reinstallation:

To adjust fuel pressure, turn the adjusting screw clockwise to increase, counterclockwise to decrease. Do not
exceed 200 psi. NOTE: When changing the fuel pump,
a bypass plug must be installed in the return port or the
fuel pump will not prime.

Reinstall by reversing the above steps 4 through 1.

Removal of Soot and Heating Coil:
In the heating process, fuel residue in the form of soot
deposits may develop on the heating coil and block air
flow which will affect burner combustion. When soot
has been detected on visual observation, the soot
on the coil must be washed off after following the coil
removal steps.

Final Note:
The 12 VDC burner systems can draw as much as 18
amps! For such burners to run properly, the battery and
engine charging system must be kept in good condition.
The engine must run at the correct RPM to adequately
charge the battery. It is equally important not to throttle
down the engine on models without batteries, since all
power to run the burner comes solely from the engine.
Do not throttle down the engine at anytime while the
machine is operating.

1. Remove the tank head assembly by lifting the tank
head off.
2. Remove the two pipe nipples and associated fittings.
3. Lift the coil out of the outer wrap.
CAUTION: The coil weighs about 80 lbs. Use proper
lifting techniques.
4. Clean, repair and replace the coil by reversing the
above steps.
