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.
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.
WARNING: Do not allow the unit to run for more than two minutes without
the gun trigger being pulled. This could cause overheating and damage to
the pump. When the temperature inside the pump rises too high, the thermal
relief valve will open and release a spray of water from the pump to lower the
internal temperature. The valve will thenclose.
Thermal Relief Valve (P, Fig. 5): When the temperature inside the
P
FIG. 5
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.

STORAGE
ENGINE
Consult the Engine Owner's Manual for manufacturer’s recommendations
forstorage.
TO PREVENT FUEL-RELATED PROBLEMS
1. Add Ethanol ShieldTM fuel stabilizer following the manufacturer’s instructions.
When adding a gasoline stabilizer, fill the fuel tank with fresh gasoline. If only
partially filled, air in the tank will promote fuel deterioration during storage. If
you keep a container of gasoline for refueling, be sure that it contains only
freshgasoline.

18- ENG
2. After adding a gasoline stabilizer, run the engine outdoors for 10 minutes
to be sure that treated gasoline has replaced the untreated gasoline in
thecarburetor.
NOTICE: Risk of property damage. Never run your pressure washer without an
adequate watersupply.
