OPERATING INSTRUCTIONS
BASIC ELEMENTS OF A PRESSURE WASHER
High Pressure Pump (located inside the shroud): Increases the pressure of the
water supply.
Engine: Drives the high pressure pump.
High Pressure Hose: Carries the pressurized water from the pump to the gun
and wand.
Spray Gun: Connects with wand to control water flow rate, direction, and
pressure.
Multi-Adjustable Spray Wand: Has a spray nozzle which adjusts from a pencil
stream (0°) to a wide angle fan spray (40°). The spray can be adjusted by twisting
the nozzle clockwise and/or counterclockwise. Also, the high and low pressure
settings can be controlled by moving the nozzle in and out. See Operation
section. See How To Use Wand paragraph in this section.
Chemical Hose: Feeds cleaning agents into the pump to mix with the
pressurized water. See How To Apply Chemicals/Cleaning Solvents in Operation
section of this manual.
READ THIS OPERATION MANUAL AND SAFETY RULES BEFORE OPERATING
YOUR UNIT. Compare the illustrations with your unit to familiarize yourself with
the location of various controls and adjustments. Save this manual for future
reference.

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.
Starter Grip: Pulling starter grip operates recoil starter to crank engine.
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 through
the pressure washer.
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 cleaners or cleaning solvents with the
pressurized 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.
12- ENG
D28600
HOW TO USE SPRAY WAND:
Your pressure washer is equipped with a multi-adjustable spray wand with both
high and low pressure settings. The high pressure setting is for cleaning and
rinsing, the low pressure setting is for applying cleaning solutions to surfaces.
When using the high pressure setting, DO NOT allow the jetlike spray to come in contact with unprotected skin, eyes, or
with any pets or animals. Serious injury can occur.
Risk of injection or injury to person. DO NOT direct
discharge stream toward persons.
For high pressure operation, pull back the nozzle of the multi-adjustable spray
wand as shown.
The nozzle at the end of the multi-adjustable spray wand can be rotated to
change the high pressure spray pattern from a narrow jet to a 40º fan shape, as
shown. Markings have been placed on the nozzle to help you select the spray
pattern.
For low pressure operation, extend the nozzle of the multi-adjustable spray wand
as shown.
