PRESSURE WASHER
TERMINOLOGY (cont'd)
Bypass Mode: Allows water to
re-circulate within pump when the gun
trigger is not pulled.
Allowing the unit to
run for more than
two minutes without the gun trigger
pulled could cause overheating and
damage to the pump.
Chemical Injection System: Mixes
cleaners or cleaning solvents with the
water to improve cleaning
effectiveness.
Water Supply: All pressure washers
must have a source of water. The
minimum requirements for a water
supply are 20 PSI and 5 gallons per
minute.
PRESSURE WASHER
OPERATING FEATURES
PRESSURE ADJUSTMENTS
The pressure setting is preset at the
factory to achieve optimum pressure
and cleaning. If you need to lower the
pressure, it can be accomplished by
these methods.
1. Back away from the surface to
be cleaned. The further away you
are, the less the pressure will be
on the surface to be cleaned.
2. Rotate the nozzle at the end of
the multi-adjustable spray wand
to widen the fan spray. The wider
fan spray will minimize the pressure
on the surface to be cleaned.
DO NOT attempt to
increase pump
pressure. A higher pressure setting
than the factory set pressure may
damage pump.
READ AND UNDERSTAND ALL WARNINGS BEFORE STARTING UNIT
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 can 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 fittings or worn or damaged hoses can result in injection
injuries. DO NOT TREAT FLUID INJECTION AS A SIMPLE CUT! See a
physician immediately!
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" 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.
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 minutes at a time. Pump
operates in bypass mode when spray gun trigger is not pressed. If pump is left
in bypass mode for more than two minutes internal components of the pump
can be damaged.
If you do not understand these precautions, please call 1-866-422-4286 to
speak to a service representative for further instructions.
