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.
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. 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.
2. Reduce the speed of the
gasoline engine (RPM). Slow the
engine down and the water
pressure will go down with it.
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 0º pencil stream to a
40º fan spray, as shown. Markings
have been placed on the nozzle to
help you select the spray pattern.

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.

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
permanent damage may occur.
Engine Preparation
• First add a fuel stabilizer to the
fuel tank.
• 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.
• Next shut off engine and
disconnect the water supply.
• Disconnect the spark plug wire
and remove the spark plug.
• Add one teaspoon of oil through
the spark plug hole.
• Place rag over spark plug hole
and pull the recoil a few times to
lubricate the combustion
chamber.
• Replace the spark plug, but do
not connect the spark plug wire.
PUMP
The 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.
1. Obtain a funnel, six ounces of RV
antifreeze or windshield washer fluid,
and approximately 12 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.
2. Disconnect spark plug wire.
3. Disconnect high pressure hose
from pump and from spray gun.
4. Connect 12 inch length of hose to
water inlet of pump.
5. Add RV antifreeze or windshield
washer fluid to hose as shown.
6. Pull engine starter rope slowly
several times until antifreeze or
windshield washer fluid comes
out of high pressure hose connec-
tion of pump.

7. Remove short hose from water
inlet of pump.
8. Install spark plug into spark plug
hole and tighten securely, then
reconnect spark plug wire.
9. Drain all water from high pressure
hose, coil it, and store it in cradle
of the pressure washer handle.
10. Drain all water from spray gun
and wand by holding spray gun in
a vertical position with nozzle end
pointing down and squeezing
trigger. Store in gun/hose holder.
11. Store chemical hose, high
pressure hose, spray gun, and
wand so they are protected from
damage, such as being run over.
