OPERATION
PRESSURE WASHER TERMINOLOGY
PSI: Pounds per Square Inch. The unit of measure for water pressure. Also used
for air pressure, hydraulic pressure, etc. Sometimes noted as “Bar”, another unit
of measure.
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 (M): When the temperature inside the pump 5
M
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 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 meth-
ods.
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. 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.
3. Reduce the speed of the gasoline engine (RPM). Slow the engine down and
the water pressure will go down with it.
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.
CHANGING NOzzLES ON SPRAY WAND
DANGER: Risk of fluid injection. Do not direct discharge stream toward
persons, unprotected skin, eyes or any pets or animals. Serious injury will
occur.

13- ENG
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). 6
KE
2. Release quick-connect coupler and twist nozzle to make
sure it is secure in coupler.
WARNING: Flying object could cause risk of serious
injury. Ensure nozzle is completely inserted in quick-
connect socket and quick-connect snap ring is fully
engaged (forward) before squeezing gun trigger.
