carburetor choke valve.
Starter Grip: Pulling starter grip
operates recoil starter to crank engine.
Engine Switch: Enables and disables
ignition system.
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 fl ow rate of water.
CU: Cleaning Units. GPM multiplied
by PSI. GPM x PSI = CU
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 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 40º nozzle -
(white) this nozzle delivers a less
powerful stream of water and a
wider spray pattern.
DO NOT attempt
to increase pump
pressure. A higher pressure setting
than the factory set pressure may
damage pump.
SPRAY WAND NOZZLES
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.
