Installation Instructions
Attaching a Water Feed Tank (157594 only)
Installing a Battery
Caution: Make sure to follow these instructions.
Inadequate plumbing between a feed tank and the
pressure washer can cause damage to the pump from
cavitation.
Cavitation will not occur if you select large fittings and
hose to connect the feed tank to the pressure washer.
Also, place the pressure washer right next to the feed
tank so the connection hose will be as short as possible.
Warning: Sulfuric acid is a corrosive poison.
Avoid contact with skin, eyes or clothing. Always
wear safety glasses. Always wear safety glasses
when working on or near the battery.
The engine will not run and the burner will not fire
without first installing a battery.
The battery box provides protection for the battery and
will accept a standard automotive battery (The inside
dimensions are 11-1/8"L x 7-3/4"W x 10-1/8"H). The
battery must be 12VDC, with a minimum rating of 18 Ah
(Amp-hour). When installing a battery, always connect
the red colored (“positive” or “+”) cable first. When
disconnecting a battery, always remove the black
colored (“negative” or “-”) cable first

IMPORTANT: Proper initial installation of equipment
will assure more satisfactory performance, longer
service life, and lower maintenance cost.
IMPORTANT: The use of a back flow preventer (Part
#222815 call 1-800-270-0810 to order) on the water
supply hose is recommended and may be required
by local code.
1.) Use ¾” connection hose no longer than 6ft long.
2.) Make sure the connection hose does not kink.
3.) Make sure all fittings are ¾” or larger.
4.) Do not use 90 elbow fittings unless absolutely
necessary.
5.) Make sure bottom of the tank is level or higher than
the bottom of the skid frame.
6.) Do not pump flammable liquids or liquids containing
incompatible chemicals or solvents.
7.) Reroute the easy start valve so it discharges back to
the feed tank. This will aid pump priming on initial
start up. The easy start valve is located below the
unloader. See Machine Component Identification for
location of unloader.
Place the pressure washer on a solid level surface in a
protected area where it is not readily influenced by
outside forces such as strong winds, freezing
temperatures, rain, etc. Locate the pressure washer for
easy access for filling fluids, adjustments, controls, and
maintenance. Position the machine so that ambient
lighting is sufficient for the surface you are cleaning to be
seen with ease. Use artificial light if needed.

Installation Instructions
Venting
Oil Burner
DANGER: Do not run machine indoors or in an
enclosed area without adequate ventilation, or in
areas where flammable vapors, (gasoline, solvents,
etc.) may be present. Do not vent exhaust gases into
a wall, a ceiling, or a concealed place.
CAUTION: All venting must be in accordance with
applicable state and federal laws, and local
ordinances. Consult local heating contractors.
Burner Air Adjustment: The oil burner is preset and
performance tested at the factory (elevation 1100 feet).
Different altitudes may require a one-time initial burner
correction.
Air Band
White
Arrow
If the pressure washer is to be used in an enclosed area,
a flue must be installed to vent burner exhaust to the
outside atmosphere. Be sure the flue is the same size
as the burner exhaust vent on the pressure washer lid.
Poor draft will cause the pressure washer to soot and
not operate properly. When selecting the location for
installation, beware of poorly ventilated locations or
areas where exhaust fans may cause an insufficient
supply of oxygen. Proper combustion can only be
obtained when there is a sufficient supply of oxygen
available for the amount of fuel being burned. If it is
necessary to install a unit in a poorly ventilated area,
outside fresh air may have to be piped to the burner and
a fan installed to bring sufficient air into the unit. Locate
the pressure washer in such a manner that the flue will
be as straight as possible and protrude through the roof
at a proper height and location to provide adequate draft.
This oil fired unit must have a draft controller installed in
the flue. A draft controller will permit proper upward air
flow of exhaust flue gases.
Locking
Screw
Burner
1.) Turn the engine and heat switches ON (Refer to
“Operation” for details). Have someone operate the
spray gun so the burner fires.
2.) Loosen the locking screw and close the air band until
black smoke appears from the burner exhaust vent.
Note the position of the white arrow on the air band.
3.) Slowly open the air band until white smoke just starts
to appear.
4.) Turn the air band half way back to the black smoke
position previously noted.
Tighten the locking
screw.
5.) Fine tune the burner air by loosening the shutter lock
screw and turning the shutter until the exhaust is
cleanest. Tighten the shutter lock screw.

WARNING: Wear eye, ear, hand, foot and skin
protection at all times while operating this pressure
washer.
DANGER: Do not point the spray wand at yourself or
at any person. Bodily injury may result from water
under high pressure.
CAUTION: Be careful on painted or delicate
surfaces. The pressure may damage the surface if
the nozzle is too close.
IMPORTANT: Your spray gun is equipped with a
built-in trigger safety latch to guard against
accidental trigger actuation and potentially
dangerous high pressure spray. Rotate the safety
latch to the locked position when not spraying.
The safety relief valve is a backup safety feature. If the
system over pressurizes, the safety relief valve will open
and relieve system pressure.
The safety relief valve is located in the high pressure line
between the unloader and the heat exchanger.
WARNING: If the safety relief valve ever discharges
water, turn the engine off and do not use the
machine until it is serviced.
Thermal Relief Valve
The thermal relief valve allows the pump to remain in
bypass without risk of overheating the pump. If high
temperatures are developed during bypass, the thermal
relief valve will open and discharge hot water onto the
ground.
The thermal relief valve is located on the unloader
bypass port.

Maintenance Instructions
Coil Descaling
Coil Desooting
In hard water areas, scale build-up within the heating coil
will occur. Scale deposits will decrease the water
temperature rise and may eventually clog the heating
coil.
1. Mix coil cleaner in a 5 gallon bucket and elevate the
bucket so it is higher than the unloader.
2. Attach the high-pressure hose to the high-pressure
water outlet on the machine. Do not hook up the
spray gun.
3. Place the other end of the high-pressure hose in the 5
gallon bucket.
4. Attach a short length of hose to the garden hose inlet
on the pump.
5. Prime the pump by filling the hose with water, then
place the end of the hose in the bucket.
6. Run the pressure washer in cold mode for 1 to 3
hours re-circulating the cleaning solution.
Poor grades of fuel oil or inadequate combustion air will
cause heavy soot build-up on the outside surface of the
heating coil. These deposits will insulate the coil. This
will restrict the airflow through the coil, further
aggravating the soot build-up.
Most coils will never require desooting. However, to
desoot a coil...
1. Wear protective clothing, goggles, and gloves.
2. Disconnect high-pressure hose on inlet side of coil
and thermostat on outlet side of coil.
3. Remove the lid and insulation lid from the heating
chamber and hoist the coil out. Be careful, the coil
weighs 125 lbs.
4. Clean the coil.
5. Reassemble the coil to the machine. Make sure the
white insulation remains in place.
6. Reattach high-pressure hose and thermostat, and
make sure all fittings are tight before using the
machine.
Warning: Do not run the burner.
7. Dispose of the cleaning solution where it is not
harmful to animals or the environment.
8. Flush with fresh water and clean the inlet strainer
when finished.
11
Long Term / Winter Storage
During cold weather, store the pressure washer indoors and move it outdoors before starting the engine.
Long Term Storage and Freeze Protection
1.) Attach a feed tank or bucket to the water inlet (feed tank). See Installation section for Attaching a Water Feed Tank
instructions.
2.) Fill feed tank with 5 gallons of RV antifreeze.
3.) Run the pressure washer in cold mode until RV antifreeze comes out the water outlet. Make sure excess antifreeze is
disposed of safely. RV antifreeze will save the components from freeze damage and keep them lubricated.
4.) Disconnect spark plug cable. Make sure the engine start switch is OFF.
5.) Disconnect the battery and store it indoors.
Short Term Freeze Protection
1.) Drain water from feed tank.
2.) Drain water from the heat exchanger by extending the high pressure hose straight. Place the end of the hose at a
level that is below the pressure washer. Remove the spray gun from the hose. Disconnect the plumbing that
connects to the heat exchanger inlet. The water will flow out of the heating coil. This will protect the coil from freeze
damage.
3.) Open both water inlet ball valves and remove the cap from the water filter. This will drain the pump and water inlet
plumbing.
