BASIC ELEMENTS
OF ENGINE
Refer to the engine manual for location and operation of engine controls.
Choke
Control:
Opens and closes carburetor
choke valve
Throttle
Control
Lever: Controls engine speed.
Fuel Valve Lever: Opens/closes
connection
between fuel tank and carburetor.
Starter
Grip: Pulling starter grip operates
recoil starter to crank engine.
PRESSURE
WASHER
TERMINOLOGY
PSh 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.
Bypass
Mode:
In Bypass Mode, the pump is recirculating water because the
trigger of the spray gun is not pulled. If unit is left in bypass mode for more than
two (2) minutes,
the water temperature
will rise to a dangerous
level and could
damage
internal components
of the pump. Any damage
to pump due to these
causes will not be covered under warranty.
DO NOT allow your unit to operate
in bypass
mode for more
than two minutes
at any time.
Overheating
of pump can
cause
damage
to pump.
Thermal
Relief Valve: In an effort to prevent extreme damage,
pumps are
equipped
with a thermal relief valve. This valve will open when the temperature
inside the pump rises too high. This valve will then release a gush of water in an
effort to lower the temperature
inside the pump. Immediately
after this occurs,
the valve will close. The thermal relief valve is part of the pump and is not visible.
to the user.
Chemical
Injection
System:
Mixes cleaning solution 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 optimum
pressure
and
cleaning.
If you need to lower the pressure,
it can be accomplished
by these
methods.
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.
Rotate
the nozzle
at the end of the multi-adjustable
spray wand to
widen
the fan spray.
The wider fan spray will minimize the pressure on the
surface to be cleaned.
DO NOT attempt
to increase
pump pressure.
A higher
pressure
setting
than the factory
set pressure
may
damage
pump.
