Applying Detergents &
General Cleaning Techniques
WARNING: Some detergents
may be harmful if inhaled or
ingested, causing severe
nausea, fainting or poisoning.
The harmful elements may
cause property damage or
severe injury.
AVERTISSEMENT: Certains
détergents peuvent être
dangereux s'ils sont inhalés ou
ingérés, provoquant de fortes nausées, des
évanouissements et l'empoisonnement. Les
éléments dangereux peuvent causer des
dommages à la propriété ou des blessures graves
STEP 1: 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 tube into the detergent
container.
STEP 2: Open detergent valve knob to desired mixture
ratio.
STEP 3: With the engine
running, pull trigger to
operate machine. Liquid
detergent is drawn into the
machine and mixed with
water. Apply detergent to
work area. Do not allow
detergent to dry on surface.
IMPORTANT: You must flush the detergent line
after each use by placing the suction tube into a
bucket of clean water, then run the pressure
washer for 2 minutes.
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 tempera-
tures. 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 (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.

Operations
Recommendations:
• 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 wash.
CAUTION - Never use:
• Insecticides, pesticides or weed killers
• Bleach, chlorine products and other corrosive
chemicals
• Liquids containing solvents (i.e., paint thinner,
gasoline, oils)
• Tri-sodium phosphate products
• Ammonia products or acid-based products
These chemicals will harm the machine and will
damage the surface being cleaned.
Ne jamais utiliser :
• Insecticides, pesticides ou herbicides
• Eau de Javel, produits à base de chlore et
autres produits chimiques corrosifs
• Liquides contenant des solvants (c.-à-d. diluant
à peinture, essence, huiles, etc.)
• Produits à base de tripolyphosphate de sodium
• Ammoniac ou produits à base d'acide
Rinsing
It will take a few seconds for the detergent to clear.

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. Re-install the oil drain plug,
then fill the crankcase with MIL-L-644-P9
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.
8. Spray the inside of the exhaust manifold with SAE
10W oil.
9. Cover all openings with tape and apply grease to
any and all unpainted surfaces.
10. Loosen the fan belt before wrapping the engine in
plastic film and storing in a dry place away from
high voltage sources and off the ground.
Storage - In excess of 6 months

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 and 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.
Maintenance & Service
Unloader Valves
Unloader valves are preset and tested at the factory
before shipping. Tampering with the factory setting may
cause personal injury and/ or property damage and will
void the manufacturer's warranty.
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
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
and water in the float tank. Turn the engine on to siphon
the anti-freeze mixture through the machine. If
compressed air is available, an air fitting can be
screwed into the float tank by removing the float tank
strainer and fitting. Then inject the compressed air.
Water will be blown out of the machine when the trigger
on the spray gun is opened.
High Limit Hot Water Thermostat
For safety, each machine is equipped with a tempera-
ture sensitive high limit control switch. In the event that
the water should exceed its operating temperature, the
high limit control will turn the burner off until the water
cools, then it will automatically reset itself. The thermo-
stat sensor is located on the discharge side of the
heating coil. The thermostat control dial is located on
the control panel.
Pumps
Use only SAE 10W-40 weight non-foaming oil. Change
oil after first 50 hours of use. Thereafter, change oil
every year 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
prevention 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 #9.804-059.0) will remove lime and other deposits
before coil becomes plugged. (See Deliming instruc-
tions for use of Deliming Powder.)
Deliming Coils
Periodic flushing of coils or optional float tank is recom-
mended.
Step 1 Fill a container with 4 gallons of water, then
add 1 lb. of deliming powder. Mix thoroughly.
Pour mixture into float tank.

Maintenance
Step 2 Remove wand assembly from spray gun and
put spray gun into float tank. Secure the
trigger on the spray gun into the open
position.
Step 3 Turn engine on, allowing solution to be
pumped through coils back into the float
tank. The solution should be allowed to
circulate 2-4 hours or until the color changes.
Step 4 After circulating solution, flush the entire sys-
tem with fresh water. Clean out float tank and
then reinstall wand assembly to spray gun.
Removal of Soot from Heating Coil
In the heating process, fuel residue in the form of soot
deposits may develop between the heating coil pipes,
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 (See Coil Removal).
Relief Valve
WARNING: The relief valve on this pressure washer
has been factory set and sealed and is a non-field
adjustable part. Tampering with the factory setting
may cause personal injury and/or property damage
and will void the manufacturer warranty. For
replacement parts refer to coil outlet assembly
exploded views.
AVERTISSEMENT: La soupape de décharge sur
cette laveuse à pression a été réglée en usine, puis
scellée, et est une pièce non réglable. L'altération
du paramètre de l'usine pourrait causer des lésions
corporelles et/ou des dommages à la propriété, et
annulera la garantie du fabricant. Pour des pièces
de rechange, se référer aux vues éclatées.
Fuel
Use clean fuel oil that is not contaminated with water
and debris. Replace fuel filter and drain the tank every
100 hours of operation.
Use diesel fuels specified to (ASTM D975) grade #1 or
#2 only. NEVER use gasoline in your fuel tank.
Gasoline is more combustible than fuel oil and could
result in a serious explosion. NEVER use crankcase or
waste oil in your burner. Fuel unit malfunction could
result from contamination.
NOTE: See Kubota engine manual for fuel
recommendations.
Fuel Control System
This machine utilizes a fuel solenoid valve located on
the fuel pump to control the flow of fuel to the
combustion chamber. The solenoid, which is normally
closed, is activated by a pressure switch when pump is
under load. When the operator releases the trigger on
the spray gun, the pump goes into by-pass relieving
pressure on the pressure switch turning off the elec-
trical 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 gives an instantaneous burn-or-no-burn
situation, thereby eliminating high and low water
temperatures and the combustion smoke normally
associated with machines incorporating a spray gun.
Periodic inspection, to insure that the fuel solenoid
valve functions properly, is recommended. This can be
done by operating the machine and checking to see
that the burner is not firing when the spray gun is in the
OFF position.
Fuel Pressure Adjustment
Fuel pressure is factory set to the serial plate. Adjust
fuel pressure by turning the regulating pressure
adjusting screw clockwise to increase, counterclock-
wise to decrease. Do not exceed 200 psi. NOTE: When
changing fuel pump, a bypass plug must be installed in
return port or fuel pump will not prime.

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.
Burner Air Adjustment
The oil burner on this machine is preset for operation at
altitudes below 1000 feet. If operated at higher alti-
tudes, it may be necessary to adjust the air band
setting. Adjust air band for a #1 or #2 smoke spot on
the Bacharach scale. 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 diesel fuels specified to (ASTM D975) grade #1 or
#2 is being used. Next, check the air adjustment on the
burner. An oily, smoky fire indicates a lack of air and the
air band should be moved to allow the air to flow
through the burner. Sharp eye-burning fumes indicate
too much air flowing through the combustion chamber.
The air band should be readjusted to allow less air to
flow through the burner.
CAUTION: If white smoke appears from burner
exhaust vent during start-up or operation, discon-
tinue use and readjust air bands.
ATTENTION: Si de la fumée blanche s'échappe de
l'évacuation du brûleur pendant le démarrage ou le
fonctionnement, cesser d'utiliser et réajuster les
bandes d'air.
NOTE: If a flue is installed, have a professional
serviceman adjust your burner for a #1 or #2 smoke
spot on the Bacharach scale.
For additional burner component information, see
Burner Assembly Exploded View page. It is recom-
mended that the oil burner be serviced yearly or as
needed. Contact your local service center.
Wayne Burner Air Adjustment
To adjust, start the machine and turn burner ON.
Loosen locking screw found in the air shutter openings
(see 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.
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
