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. GPM x PSI = CU
Bypass Mode: Allows water to
re-circulate within pump when the gun
trigger is not pulled.
Allowing the unit to
run for more than
two minutes without the gun trigger
pulled could cause overheating and
damage to the pump.
Chemical 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.
HOW TO USE
IMPORTANT: Read and understand
how to use the pressure washer
before operating.
TO ADJUST PRESSURE
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.
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 chemicals or
cleaning solutions to surfaces.
When using the high
pressure setting, DO
NOT allow the jet-like 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 0° pencil stream to a
40° fan spray, as shown. Markings
have been placed on the nozzle to
help you select the spray pattern.

low
pressure
The powerful 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

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.
4. After use of chemicals, place
chemical 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 when spray wand is inthe high
pressure setting.

ENGINE
IMPORTANT: It is important to prevent
gum deposits from forming in essential
fuel system parts such as the
carburetor, fuel filter, hose or tank
during storage. Also, experience
indicates that alcohol-blended fuels
(called gasohol or using ethanol or
methanol) can attract moisture which
leads to separation and formation of
acids during storage. Acidic gas can
damage the fuel system of an engine
while in storage. To avoid engine
problems, the fuel system should be
emptied before storage of 30 days or
longer. Never use engine or carburetor
cleaner products in the fuel tank or per-
manent damage may occur.
Engine Preparation
1. First add a fuel stabilizer to the
fuel tank.
2. Run pressure washer for a full 5
minutes to allow fuel stabilizer to
enter the fuel system.
While preparing the
engine make sure
water supply is turned on and
flowing to the unit. NEVER run unit
without water supply running
through pump. Failure to do so will
cause pump damage.
3. Next shut off engine and
disconnect the water supply.
4. Disconnect the spark plug wire
and remove the spark plug.
5. Add one teaspoon of oil through
the spark plug hole.
6. Place rag over spark plug hole and
pull the recoil a few times to
lubricate the combustion chamber.
7. Replace the spark plug, but do not
connect the spark plug wire.
PUMP
1. Drain all water from high pressure
hose, coil it, and store it in cradle
of the pressure washer handle.
2. Drain all water from spray gun and
spray wand by holding spray gun
in a vertical position with nozzle
end pointing down and squeezing
trigger. Store in gun/hose holder.
3. Store chemical hose, high pressure
hose, spray gun, and spray wand
so they are protected from dam-
age, such as being run over.
IThe manufacturer recommends using
a pump protector/winterizer when
storing the unit for more than 30 days
and/or when freezing temperatures are
expected. If a pump protector/winterizer
is not available, *RV antifreeze needs to
be run through the pump as outlined in
the steps below.
NOTE: Using a pump protector/winterizer
or *RV antifreeze is to provide proper
lubrication to the internal seals of the
pump regardless of temperature or
environment.
4, Obtain a funnel, six ounces of *RV
antifreeze, and approximately 36
inches of garden hose with a male
hose connector attached to one
end.
Use only RV
antifreeze. Any other
antifreeze is corrosive and can
damage pump.
5, Disconnect spark plug wire,
6, Connect 36 inch length of hose to
water inlet of pump.
7. Add *RV antifreeze to hose as
shown.

8. Pull engine starter rope slowly
several times until antifreeze
comes out of high pressure hose
connection of pump.
9. Remove short hose from water
inlet of pump.
10. Reconnect spark plug wire.
*Windshield washer fluid may also be
used
