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.
CU: Cleaning Units. GPM multiplied by PSI equals CU.
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.
NOTICE: Allowing the unit to run for more than two minutes without the gun trig-
ger being pulled could cause overheating and damage to the pump. Do not let the
pressure washer run for more than two minutes in Bypass Mode. Turn off the engine
and relieve the pressure in the gun during these extended situations.
Thermal Relief Valve (P, Fig. 5): When the temperature inside the 5
P
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.
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 meth-
ods.
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. Change to the 40˚ nozzle (white). This nozzle delivers a less powerful stream
of water and a wider spray pattern. Refer to How To Use Spray Wand.
NOTICE: DO NOT attempt to increase pump pressure. A higher pressure setting
than the factory set pressure may damage pump.
HOW TO USE SpRAY WAND
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.
CHANGING NOzzLES ON SpRAY WAND (FIG. 6)
DANGER: Risk of fluid injection. Do not direct discharge stream toward
persons, unprotected skin, eyes or any pets or animals. Serious injury will
occur.
WARNING: Flying objects could cause risk of serious injury. Do not attempt
to change nozzles while pressure washer is running. Turn engine off before
changing nozzles.

2. Release quick-connect coupler and twist nozzle to

low pressure applies cleaning
solutions Low pressure spray is safe on all
surfaces. Always verify
compatibility of cleaning
solution prior to use.
*NOTICE: The high pressure spray from your pressure washer is capable of
causing damage to surfaces such as wood, glass, automobile paint, auto striping
and trim, and delicate objects such as flowers and shrubs. Before spraying, check
the item to be cleaned to assure yourself that it is strong enough to resist damage
from the force of the spray.
HOW TO AppLY CHEMICALS/CLEANING SOLVENTS (FIG. 7)
Applying chemicals or cleaning solvents is a low pressure operation. NOTE: Use
only soaps and chemicals designed for pressure washer use. Do not use bleach.
To Apply chemicals
1. Ensure detergent siphon hose (F, Figure 7) is
F
7
attached to barbed fitting location near high
pressure hose connection of pump as shown.
2. Place other end of detergent siphon hose with
filter on it into container holding chemical/cleaning
solution. NOTE: For every 7 gallons of water
pumped 1 gallon of chemical/cleaning solution will
be used.
3. Install low pressure (black) nozzle into quick connect fitting of spray wand, see
How To Use Spray Wand paragraph in this section.

14- ENG
4. After use of chemicals, place detergent siphon hose into container of clean
water and draw clean water through chemical injection system to rinse system
thoroughly. If chemicals remain in the pump it could be damaged. Pumps
damaged due to chemicals will not be covered under warranty.
NOTE: Chemicals and soaps will not siphon if the black soap nozzle is not installed
on the spray wand.
STARTING (FIG. 8–11)
WARNING: To reduce the risk of injury, read the pressure washer instruction
manual and the engine instruction manual before starting pressure washer.
DANGER: Risk of fluid injection and laceration. When using the high
pressure setting, DO NOT allow the high pressure spray to come in contact
with unprotected skin, eyes, or with any pets or animals. Serious injury will
occur.

let the engine cool and release all water pressure before performing any
maintenance or repair. The engine contains flammable fuel. Do not smoke or
work near open flames while performing maintenance.
To ensure efficient operation and longer life of your pressure washer, a routine
maintenance schedule should be prepared and followed. If the pressure washer is
used in unusual conditions, such as high-temperatures or dusty conditions, more
frequent maintenance checks will be required.
ENGINE
Consult the Engine Owner's Manual for the manufacturer's recommendations
for any and all maintenance. NOTE: The engine drain plug is located at the rear of
