IMPORTANT SAFETY WARNINGS
WARNING
Serious injury or death may occur from a fire caused by a muer spark.
Serious injury or death may occur if system safety’s are not properly maintained.
• A spark arrester must be added to the muer of this engine when using on land covered with any
flammable agricultural crop (hay and grain), and if they are used in or near brush or forested areas. The
arrester must be maintained in eective working order by the operator of the equipment. In the state
of California, the above is required by law. (Section 4442 and 4443 of the California Public Resources
Code.) Other states/provinces may have similar laws. Federal laws apply on Federal lands.
• This pressure washer has a Safety Relief Valve . This should never be altered, modified, removed or
made inoperative. If the device fails, replace immediately with genuine manufacturer replacement part.
WARNING
Serious injury or death may occur from inhaling engine/burner exhaust or dangerous
vapors. The engine exhaust from this product contains chemicals known to the State of
California to cause cancer, birth defects, or other reproductive harm.
• Never operate this pressure washer in an enclosed area. Always ensure there is adequate ventilation
(fresh outside air) for breathing and combustion. This will prevent the buildup of dangerous carbon
monoxide gases. Beware of poorly ventilated areas, or areas with exhaust fans which can cause poor
air exchange. This unit should only be used outdoors to ensure ventilation is never an issue.
• Follow all safety instructions provided with the materials you are spraying. Use of a respirator may be
required when working with some materials. Do not use this pressure washer to dispense hazardous
detergents.
WARNING
Serious injury or death could occur from high pressure spray penetrating the skin.
• Keep clear of nozzle and spray! Never put your hand, fingers or body directly over the spray nozzle.
• Do not direct discharge stream at self, other persons, or pets.
• This product is to be used only by trained operators.
• Always keep operating area clear of other people.
• Do not allow children to operate this unit or be in the vicinity while you operate it.
• Seek emergency medical care if spray seems to have penetrated the skin. Do not treat as a simple cut!
• High pressure hoses and fuel lines should be inspected daily for signs of wear. If evidence of failure
exists, promptly replace all suspect hoses and fuel lines to prevent the possibility of injury from the
high pressure spray. If a hose or fitting is leaking, do not place your hand on the leak.
• Never operate the gun with the trigger held in the open position. To prevent accidental discharge, the
trigger gun should be securely locked when not in use.
• Before removing the spray nozzle or servicing the unit, always shut the unit o and pull the trigger of
the gun to release trapped pressure (even after you shut o the unit, there is high pressure water left in
the pump, hose and gun until you release it by pulling the trigger the gun).
WARNING
Serious injury or death may occur from contact with electricity.
• Do not direct spray on or into electrical installations of any kind! This includes electrical outlets, light
bulbs, fuse boxes, transformers, and the unit itself.
• Do not allow metal components of the pressure washer to come in contact with live electrical
components.

Serious injury may occur from touching the gasoline engine, muer, or heat exchanger. These
areas can remain hot for some time after the pressure washer is shutdown.
• Never allow any part of your body to contact the gasoline engine, muer, or heat exchanger.
WARNING
Serious injury may occur to the operator from moving parts on the pressure washer.
• Before making any adjustments, be certain the engine is turned o and the ignition cable(s) is removed
from the spark plug(s). Turning the machinery over by hand during adjustment or cleaning might start the
engine and machinery with it.
• Do not operate the unit without all protective covers in place.
WARNING
Serious injury may occur from a pressure washer malfunction or exploding accessories if
incorrect system components, attachments, or accessories are used.
Serious injury or death may occur if attempting to start the pressure washer when the
pumping system is frozen.
• Never make adjustments to the factory set pressures.
• Never exceed manufacturers maximum allowable pressure rating of attachments.
• Do not allow any hoses to make contact with heat exchanger to prevent the possibility of bursting. Avoid

where to place a supply air duct. Take care
that this opening will not promote drafts
which could blow out the pilot light.
Keep the area around the machine clear so
this air can get to the burner.
APPLIANCE IN CONFINED SPACE
The confined space shall have two per-
manent openings: one near the top of the
enclosure and one near the bottom of the
enclosure. Each opening shall have a free
area of not less than one (1) square inch
per 4000 BTU’s per hour of the total input
of all appliances within the enclosure. The
openings shall have free access to the room
interior which should have adequate infiltra-
tion from the outside.
OUT DOOR ROOF STACK SPACING RE-
QUIREMENTS

two minutes
3) Shut o “pump” and activate spray gun
to release pressure in the line
4) Shut o gas supply valve if machine is to
be left for long periods of time
CHANGING PRESSURE
The variable Unloader Valve is already set
to full pressure. Do not adjust the Unloader
past the maximum pressure, as this will not
increase the performance, and the excessive
shut-o pressure will damage the Washer.
CLEANING CHEMICALS
For chemical application, a chemical injec-
tor is required. Open the valve at the lance.
To change concentration, adjust metering
valve toward open or close. Use only chem-
icals with a pH between 7.0 and 10.0. For
stronger chemical, use a Downstream Injec-
tion System. (Contact dealer for details.)
CAUTION
The force of the water leaving the nozzle
causes a kick-back or recoil at the trigger
gun.
