WARNING: Risk of fire, asphyxiation and burning. NEvER fill fuel
tank when engine is running or hot. Do not smoke when filling fuel tank.
• NEvER fill fuel tank completely. Fill tank to 1/2" (12.7 mm) below
bottom of filler neck to provide space for fuel expansion. Wipe any
fuel spillage from engine and equipment before starting engine.
• NEvER run engine indoors or in enclosed, poorly ventilated
areas. Engine exhaust contains carbon monoxide, an odorless
and deadly gas.
• DO NOT let hoses come in contact with very hot engine
muffler during or immediately after use of your pressure
washer. Damage to hoses from contact with hot engine
surfaces will NOT be covered by warranty.
cAutIoN: NEvER pull water supply hose to move pressure washer.
This could damage hose and/or pump inlet.
• DO NOT use hot water, use cold water only.
• NEvER turn water supply off while pressure washer engine is
running or damage to pump will result.
• DO NOT stop spraying water for more than two
T
minutes at a time. Pump operates in bypass
mode when spray gun trigger is not pressed.
When the temperature inside the pump rises
too high the thermal relief valve (T) will open
and release a gush of water in an effort to lower
the temperature inside the pump. The thermal
relief valve will then close. If pump is left in bypass mode for
more than two minutes internal components of the pump can
be damaged.

is present, turn the water source off.
4. Verify the filter screen (U) is in water inlet of pump.
U
The cone side faces out.
5. Connect the cold water source (V) to pump inlet.
note: Water source must provide a minimum of
5 gallons per minute at 0 PSI.
WARNING: To reduce the possibility of contamination always pro-
tect against backflow when connected to a potable water system.
6. Connect high-pressure hose (C) to pump
V
C outlet.
7. If applying a chemical or cleaning solution,
refer to chemicals and cleaning
solvents.
8. Turn the water source on.
cAutIoN: Risk of property damage. Failure
to do so could cause damage to the pump.
9. Remove all air from the pump and high pressure hose by depress-
ing trigger until a steady stream of water is present.
10. Start engine. Refer to the engine instruction manual for correct
procedure.
WARNING: Risk of unsafe operation. If engine does not start
after two pulls, squeeze trigger of gun to relieve pump pressure. Pull
starter cord slowly until resistance is felt. Then pull cord rapidly to
avoid kickback and prevent hand or arm injury.
11. Depress trigger on gun to start water flow.
WARNING: Risk of unsafe operation. Stand on a stable
surface and grip gun/wand firmly with both hands. Expect the gun to
kickback when triggered.
