OPErATION
PRESSURE WAShER
TERMINOLOGY
PSI: Pounds per Square Inch. The
unit of measure for water pressure.
Also used for air pressure, hydraulic
pressure, etc.
GPM:
Gallons per Minute. The unit of
measure for the flow rate of water.
CU: Cleaning Units. GPM multiplied by
PSI equals CU.
Bypass Mode: Allows water to
re-circulate within the pump when the
gun trigger is not pulled. This feature
allows the operator to release the
trigger gun and reposition themselves
without having to turn the engine off in
between cleaning actions.
NOTICE:
Allowing the unit to run for
more than two minutes without the
gun trigger being pulled could cause
overheating and damage to the pump.
Do not let the pressure washer run
for more than two minutes in Bypass
Mode. Turn off the engine and relieve
the pressure in the gun during these
extended situations.
Thermal Relief Valve
17
P
(P):
When the
temperature inside the
pump rises too high,
this valve will open and
release a gush of water in an effort to
lower the temperature inside the pump.
The valve will then close.
Detergent 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. If your water source is a well,
the garden hose length can only be
30 ft. (9 m) max.
WARNING: To reduce the
possibility of contamination always
protect against backflow when
connected to a potable water system.

OPERATING fEATURES
PRESSURE ADJUSTMENTS
The pressure setting is preset at the
factory to achieve op ti mum pres sure
and cleaning. If you need to lower the
pres sure, it can be accomplished by
these meth ods.
1. Back away from the sur face to
be cleaned. The further away you
are, the less the pressure will be on
the surface to be cleaned.
2. Change to the 40˚ nozzle (white).
This nozzle delivers a less powerful
stream of water and a wider spray
pattern. Refer to
how To Use
Spray Wand .
NOTICE: DO NOT attempt to increase
pump pressure. A higher pressure
setting than the factory set pressure
may damage pump.
hOW TO USE SPRAY WAND
The nozzles for the spray wand are
stored in the nozzle holder on the panel
assembly. Colors on the panel identify
nozzle location and spray pattern.
Refer to the following chart to choose
the correct nozzle for the job to be
performed.

DANGER: Risk of fluid injection.
Do not direct discharge stream
toward persons, unprotected skin,
eyes or any pets or animals. Serious
injury will occur.
WARNING: flying objects could
cause risk of serious injury. Do not
attempt to change nozzles while
pressure washer is running. Turn
engine off before changing nozzles.
1. Pull quick-connect coupler (E)
back and insert nozzle (K).
