PRESSURE WASHER
High Pressure Pump (located
inside the shroud): 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 wand.
Spray Gun: Connects with wand to
control water flow rate, direction, and
pressure.
Multi-Reg Wand: Has a spray nozzle
which adjust from a pencil stream (0°)
to a wide angle fan spray (40°). The
spray can be adjusted by twisting the
nozzle clockwise and/or counter-
clockwise. Also, the high and low
pressure settings can be controlled
by moving the nozzle in and out. See
Operation section.

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. Reduce the speed of the gaso-
line engine (RPM). Slow the
engine down and the water pres-
sure will go down with it.
DO NOT attempt to
increase pump
pressure. A higher pressure set-
ting than the factory set pressure
may damage pump.
HOW TO USE
IMPORTANT: Read and understand
how to use the pressure washer
before operating.
TO USE WAND
Your pressure washer is equipped
with a multi-reg 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 solu-
tions to surfaces.
Risk of injection or
injury to person. Do
not direct discharge stream toward
persons, unprotected skin, eyes, or
towards any pets or animals.
Serious injury can occur.
For high pressure operation, pull back
the nozzle of the multi-reg wand as
shown.
PRESSURE WASHER
TERMINOLOGY
NOTE: Become familiar with this ter-
minology before operating.
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
through the pressure washer.
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 dan-
gerous level and damage internal
components of the pump.Any dam-
age 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 damage, pumps are
equipped with a thermal relief valve.
This valve will open when the temper-
ature inside the pump rises too high.
This valve will then release a gush of
water in an effort to lower the tem-
perature inside the pump.
Immediately after this occurs, the
valve will close.
Chemical Injection: Feeds cleaning
agents into the pump to mix with the
pressurized water and help in clean-
ing.
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.

12- ENG

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 contami-
nate 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 disas-
sembly. For this reason an Authorized
Warranty Service Center should clean
the air cooling system per recom-
mended intervals.

ENGINE
IMPORTANT: It is important to prevent
gum deposits from forming in essential
fuel system parts such as the carbure-
tor, fuel filter, hose or tank during stor-
age. Also, experience indicates that al-
cohol-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 sys-
tem of an engine while in storage. To
avoid engine problems, the fuel sys-
tem 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 flow-
ing 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 discon-
nect 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 cham-
ber.
•Replace the spark plug, but do
not connect the spark plug wire.
PUMP
It is recommended that you follow
these steps to protect the internal
seals of the pressure washer when
storing the unit for an extended
period and WHEN FREEZING TEM-
PERATURES ARE EXPECTED.
NOTE: If storing the unit for more
than 30 days RV antifreeze or wind-
shield washer fluid needs to be run
through the pump. This helps pre-
vent damage within the pump head.
RV antifreeze or windshield washer
fluid is not only added for winteriz-
ing, but for proper lubrication
regardless of temperature or envi-
ronment. Storing the pump less than
30 days does not require the RV
antifreeze or windshield washer
fluid.
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.
STORAGE

6. Pull engine starter rope slowly
several times until antifreeze or
windshield washer fluid comes
out of high pressure hose con-
nection 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 pres-
sure hose, spray gun, and wand
so they are protected from dam-
age, such as being run over.
