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 Spray Wand paragraph in this section.

Chemical Injector Rinsing Hose (not shown): Rinses the chemical injector after
use of cleaning solution.

Dual Tank Cleaning System: Allows easily switching from one cleaning solution
to another depending on the cleaning task by simply turning the control valve
knob.

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.
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

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.
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.

13- ENG

D27918

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.

HOW TO USE THE DUAL TANK CLEANING SYSTEM

NOTE: Use only soaps and cleaning solutions designed for pressure washer use.
Do not use bleach.

To apply cleaning solutions:

1. Make sure cleaning solution tanks are assembled and all hoses are
connected.

2. Turn control valve knob arrow to the down (off) position as shown.

3. Fill cleaning solution tanks with desired cleaning solution. Each tank
holds approximately 1.25 gallon. NOTE: The cleaning solution/water ratio

is 7:1, for every 7 gallons of water pumped, 1 gallon of cleaning solution will
be used.

Never fill cleaning solution tanks with gasoline or other
flammable solvent.

4. Turn control valve knob toward tank with desired cleaning solution.

5. Set multi-adjustable nozzle to low pressure setting. See How To Use Spray

Wand paragraph in this section.

6. After use of cleaning solution the chemical injector MUST be rinsed, follow
the instructions in the Shutting Down paragraph after each use.

NOTE: Cleaning solutions will not siphon when spray wand is in the high

pressure setting.

DUAL TANK CLEANING SOLUTION TIPS

1. Each tank may be filled with different cleaning solutions depending on the
task to be performed. Example: deck and driveway. Fill one tank with deck
cleaning solution and the other with driveway cleaning solution. Clean the
deck with the deck cleaning solution and then simply turn the control knob
toward the driveway cleaning solution and clean the driveway.

2. If only one cleaning solution is being used both tanks may be filled with the
same solution to double the capacity before refilling tanks.

3. If only one cleaning solution is being used the second tank may be filled with
clean water to conveniently rinse the chemical injector after use.
