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.  
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.  
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.  
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.  
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.  
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.  
Unloader  
Plug this  
port  
Make a partition between the wash area and the  
pressure washer to prevent direct nozzle spray from  
coming in contact with the pressure washer. Moisture  
reaching the equipment will reduce the pressure  
washer’s service life.

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.  
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.  
CAUTION: All venting must be in accordance with  
applicable state and federal laws, and local  
ordinances. Consult local heating contractors.  
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 (Part #18007 call 1-800-270-0810 to order). A  
draft controller will permit proper upward air flow of  
exhaust flue gases.  
Locking

Screw  
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.

Safety Features  
XI.) Cleaning  
Safety Relief Valve  
WARNING: Wear eye, ear, hand, foot and skin  
protection at all times while operating this pressure  
washer.  
The safety relief valve is a backup safety feature. If the  
system over pressurizes, the safety relief valve will open  
and relieve system pressure.  
DANGER: Do not point the spray wand at yourself or  
at any person. Bodily injury may result from water  
under high pressure.  
The safety relief valve is located in the high pressure line  
between the unloader and the heat exchanger.  
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.  
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.  
Safety Latch  
The thermal relief valve is located on the unloader  
bypass port.

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.
