2.) To reduce the risk of injury, close supervision is necessary when the product is used near children. Do not allow irresponsible use by children. Always stop the product and bleed pressures before leaving unattended, disconnecting hoses, or servicing the pump.

3.) Know how to stop the product and bleed pressures quickly. Be thoroughly familiar with the controls.

4.) Stay alert - watch what you are doing.

5.) Do not operate the product when fatigued or under the influence of alcohol or drugs. Never smoke while operating or fueling this machine.

6.) Keep operating area clear of all persons.

7.) Do not overreach or stand on unstable support. Keep good footing and balance at all times. Wear footwear capable of maintaining a good grip on wet surfaces - Do not place the machine on soft or unstable ground.

8.) Follow the maintenance instructions specified in all manuals. Do not run machine without sufficient lubrication or sufficient water to cool the pump.

9.) Wear safety glasses, gloves, face protection and appropriate clothing when operating the machine.

10.) Do not operate this machine with broken or missing parts. - Never alter the manufacturer’s original design or deactivate any safety device on the machine.

11.) Risk of exposure to dangerous chemicals. Wear protective gloves when handling and cleaning with chemicals. Follow the chemical manufacturer’s directions. Understand all safety hazards and first aid for all chemicals being used. Check whether dangerous chemicals have been used and take any precautions that may have been recommended by the supplier of these chemicals when cleaning filters. Do not pump highly abrasive fluids or use with incompatible chemicals or solvents.

12.) Know the pressure and temperature limits of your machine. Be sure all high pressure accessories meet or exceed your machine’s limits. Do not set the pressure relief valve above the machine’s limit.

13.) Do not move this machine by pulling on the hose. Do not use the pump to support other items of equipment that impose unacceptable loads on the pump. Do not attempt to use this machine as a prop.

14.) To reduce risk of injury, do not secure the spray gun open. Your spray gun is equipped with a built-in trigger safety latch to guard against accidental trigger release and potentially dangerous high pressure spray. Rotate the safety latch to the locked position when not spraying.

15.) Do not clean this machine with its own spray. Cleaning should be done with a damp sponge with the engine OFF.

16.) NEVER attempt to immediately run or re-light the burner if it doesn’t ignite the first time. Unburned oil or gas may have accumulated causing potential explosion or fire hazard.

17.) Always make sure all switches and controls are in the OFF position prior to starting the engine.

Installing a Battery

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

Location

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.

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.

Attaching a Water Feed Tank (157594 only)

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.

Connec feed line

here

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.

Unloade

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

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.

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.

Oil Burner

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.

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.

CAUTION: If white smoke appears from the burner exhaust vent during start-up or operation, discontinue use and readjust air bands. NOTE: If a flue is installed, have a professional serviceman adjust your burner for a #1 or #2 smoke spot on the Bacharach scale.
