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.
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
IMPORTANT: Read and understand
how to use the pressure washer
before operating.
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
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.

11- ENG D28236
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 APPLY CHEMICALS
AND CLEANING SOLVENTS
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.
1. Press chemical hose onto barbed
fitting located near high pressure
hose connection of pump as
shown.
2. Place other end of chemical hose
with filter on it into container holding
chemical/cleaning solution. NOTE:
The chemical/water ratio is 7:1, for
every 7 gallons of water pumped 1
gallon of chemical/cleaning solution
will be used.
3. Set multi-adjustable nozzle to low
pressure setting. See How To Use
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 in the high
pressure setting.
Barb fitting
TO SHUT DOWN
IMPORTANT: Read and understand
how to shut down the pressure
washer before operating.
1. If you have applied chemicals,
place chemical hose into container
of clean water and draw clean
water through chemical injection
system to rinse system thoroughly.
NOTE: Failure to do so could
cause damage to the pump.
2. Turn engine off by placing the
throttle control in the STOP
position.
NOTE: NEVER turn the water off

on water supply.
11. Start pressure washer and place
wand into high pressure setting to
test.
PUMP
This screen filter should be checked
periodically and cleaned if necessary.
1. Remove filter by grasping end and
removing it from water inlet of
pump as shown.
2. Clean filter by flushing it with water
on both sides.
3. Re-insert filter into water inlet of
pump. NOTE: Cone side faces

washer without filter properly installed.
Filter Screen
Cleaning Debris
Engine parts should be kept clean to
reduce the risk of overheating and
ignition of accumulated debris.
NOTE: Do not use water to clean
engine parts. Water could contaminate
fuel system. Use a brush or dry cloth.
Combustion Deposits
Every 100-300 hours an Authorized
Warranty Service Center should
remove combustion deposits from the
cylinder, cylinder head, top of piston,
and around valves.
Air Cooling System
Over time debris may accumulate in
cylinder cooling fins and cannot be
observed without partial engine
disassembly. For this reason an
Authorized Warranty Service Center
should clean the air cooling system per
recommended intervals.

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.
It is recommended that you follow
these steps to protect the internal seals
of the pressure washer when STORING
THE UNIT FOR MORE THAN 30 DAYS
AND/OR WHEN FREEZING
TEMPERATURES ARE EXPECTED.
*RV antifreeze needs to be run through
the pump as outlined in the steps
below.
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.
