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 trig-
ger 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 (P, Fig. 5): When the temperature inside the
5
P
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.

pRESSURE ADJUSTMENTS
The pressure setting is preset at the factory to achieve op
ti mum
pres
sur
e and
cleaning. If you need to lower the pres
sur
e, it can be accomplished by these meth-
ods.
1.
Back away fr
om 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.

USE SpRAY W
AND
The nozzles for the spray wand ar
e 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.
