high-pressure setting.
Starting
WARNING: To reduce the risk of injury, read the pressure washer
instruction manual and the engine instruction manual before starting
pressure washer.
DANGER: Risk of fluid injection and laceration. When using the high-
pressure setting, DO NOT allow the high-pressure spray to come in
contact with unprotected skin, eyes, or with any pets or animals. Serious
injury will occur.
• Your washer operates at fluid pressures and velocities high
enough to penetrate human and animal flesh, which could result
in amputation or other serious injury. Leaks caused by loose fit-
tings or worn or damaged hoses can result in injection injuries.
DO NOT TREAT FLUID INJECTION AS A SIMPLE CUT! See a
physician immediately!
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 in doors or in en closed, poorly ven ti lat ed
areas. En gine exhaust con tains carbon mon ox ide, 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 pres sure 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
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 (U) 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.
