OPERATING INSTRUCTIONS
BASIC ELEMENTS OF A PRESSURE WASHER
High Pressure Pump: 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 spray wand.
Spray Gun: Connects with spray wand to control water flow rate, direction, and
pressure.
Quick Connect Spray Wand: Spray wand is equipped with a female quick
connect coupler on the end. This allows the user to quickly change out high-pressure nozzles for different spray patterns and change to the soap nozzle for low
pressure and chemical/soap applications. See How To Use Spray 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.

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.
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. 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.
3. Adjust the pressure regulator on the pump. Turn t h e
pressure regulator knob counterclockwise to lower
pressure. Refer to the illustrations to identify your pressure regulator. Once you have finished using your pressure washer, return the pressure regulator to its original
position by turning it clockwise.
DO NOT try to turn pressure regulator knob
past the built-in stop or damage to pump
will result.

TO USE SPRAY WAND
Your pressure washer is equipped with five spray nozzles. Each nozzle is color
coded and delivers a specific spray pattern for a particular cleaning purpose.
The size of the nozzle determines the size of the fan spray and the pressure out
of the nozzle. The 0º, 15º, 25º, and 40º nozzles are high pressure nozzles. The
chemical nozzle is a low pressure nozzle.
The nozzles are housed in receptacles on the panel of the pressure washer
handle. Colors on the panel identify nozzle location and spray pattern.
Risk of injection or injury to person. Do not direct discharge
stream toward persons, unprotected skin, eyes, or any pets
or animals. Serious injury can occur.
Changing Nozzles
DO NOT attempt to change nozzles
while pressure washer is running.
Turn engine off before changing nozzles.
1. Pull quick connect coupler back and insert nozzle.
2. Release quick connect coupler and twist nozzle to
make sure it is secure in coupler.
Risk Of Injury. Ensure nozzle is
completely inserted in QC socket, and
QC snap ring is fully engaged (forward) before
squeezing gun trigger.
0º nozzle - Red. This nozzle delivers a pinpoint
stream and is extremely powerful. It covers a very
small area of cleaning. This nozzle should only be
used on surfaces that can withstand this high
pressure such as metal or concrete. Do not use on
wood.
15º nozzle - Yellow. This nozzle delivers a powerful
15 degree spray pattern for intense cleaning of small
areas. This nozzle should only be used on areas that
can withstand the high pressure from this nozzle.
25º nozzle - Green. This nozzle delivers a 25
degree spray pattern for intense cleaning of larger
areas. This nozzle should only be used on areas that
can withstand the pressure from this nozzle.
40º nozzle - White. This nozzle delivers a 40 degree
spray pattern and a less powerful stream of water. It
covers a wide area of cleaning. This nozzle should
be used for most general cleaning jobs.
Low pressure nozzle - Black. This nozzle is used
to apply chemicals or cleaning solutions. It has the
least powerful stream.
