Manual for Safety, Operation, and Maintenance
Instructions.
Note: Included with your unit is a video cassette that
demonstrates how to operate your pressure washer.
If you have a video cassette recorder you should to
view the video before operation.
Before Starting The Engine
To operate the engine you will need to do the following.
Note: Your pressure washer pump is a sealed pump,
you should never have to add or change the oil.
A CAUTION: Always check engine oil level before
every start. Running engine low of oil or out of oil
could result in serious damage.
A WARNING: Never adjust spray pattern when
spraying. Never put hands in front of spray nozzle to
adjust spray pattern you could be injured.
Stopping Your Pressure Washer
A CAUTION: Do not run pump without the water
supply connected and turned on. Failure to do so
will result in pump damage.
Move throttle control to the stop position to turn
pressure washer off.
Z
■ THROTTLE
CONTROL
Simply shutting OFF engine will not release pressure
in the system. After engine has stopped, squeeze
the trigger on the spray gun for about 3 seconds to
relieve pressure. Spray stream will decrease in
length.
Engine Oil
Your unit has been shipped without oil in the engine. A
bottle of SAE 30 weight oil is included in the carton.
Remove oil dip stick located on top of the engine. Oil
capacity is about 20 ounces of oil. The oil dip stick is
clearly marked with a line that tells you when unit has
enough oil. To check oil, place dipstick into oil fill.
Tighten dipstick then remove. Do not fill above this
point. Pour slowly.
^ 'll
NOTE: When adding oil to the engine crankcase, use a
high quality detergent oil classified “For Service SF, SG,
SH, rated SAE 30 weight. Use no special additives.
Select the oil’s viscosity grade according to your ex
pected operating temperatures.

IMPORTANT: This unit is equipped with a thermal relief
valve. If unit is allowed to run for several minutes
without pressing the trigger on the spray gun, several
drops of water may be released through this valve to
cool the unit. This small amount of water will drip from
the bottom of the pump.
Although multi-viscosity oils (5W30,10W30, etc.)
improve starting in clod weather, these multi-viscosity
oils will result in increased oil consumption when used
above 40°F Check your engine oil level more frequently
to avoid possible damage from running low on oil. Oil
sump capacity is 20 ounces.
Gasoline
Your pressure washer engine is 4 cycle. Use unleaded
fuel only.
A CAUTION: Do not overfill the fuel tank. Always
allow room for fuel expansion.
A WARNING: Never fill fuel tank indoors. To avoid
explosion and injur/, never fill fuel tank when
engine is running or hot. Do not smoke or have
open flame when filling fuel tank.
Use clean, fresh, regular unleaded gasoline with a
minimum of 85 octane. Do not mix oil with gasoline. If
mleaded fuel is unavailable leaded fuel may be used.
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 forma
tion 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.
A CAUTION: Never start pressure washer without
water source turned on and connected to
pressure washer. Failure to do so will cause
pump damage.
To Start Your Pressure Washer
• Squeeze trigger on pressure washer wand to relieve
air pressure caused by turning on the water. Water
will spew out of the gun in a thin stream. This will
make it easier to start the engine.
Engage the safety latch on the spray gun. This locks
the trigger in place and keeps you from accidentally
spraying a high pressure stream.
SAFETY
LATCH
• On the engine there is a choke/run lever. Place lever
to the choke position.
• Remove gas cap.
• Add unleaded gasoline, slowly, to fuel tank.
• Do not overfill.

with throttle in the rabbit (high speed) position.
CHOKE.
• Grasp the starter grip and pull slowly until resistance
is felt,then pull firmly to start engine.
NOTE: If engine does not start right away, squeeze the
trigger on the gun to relieve air pressure caused by
turning on the water. Water will spew out of the gun in a
thin stream. This will make it easier to pull start the
engine. If more than five pulls, place choke level back to
run position.
• When engine starts, gradually move choke lever to
RUN position.
4
• For hot engine restarts, make sure throttle is in the
rabbit (high speed) position and the choke lever is in
the RUN position.

is felt, then pull firmly to start engine.
How To Use Your Pressure Washer
Using Soaps/Chemicals
On the end of your spray gun is a nozzle that you can
slide forward and backward and that you can also
St from side to side. With the adjustable nozzle you
v.an adjust the spray pattern to either high pressure
or low pressure. You can also adjust the spray so it is
concentrated in a stream pattern or expanded into a fan
pattern.
• Slide the nozzle in a forward position to draw chemical
and achieve low pressure. Pull nozzle back for high
pressure.
HIGH PRESSURE LOW PRESSURE
To adjust your spray pattern twist the nozzle
clockwise for fan spray or counterclockwise for
stream spray.
STREAM SPRAY
For most effective cleaning, keep spray nozzle
between 8 and 24 inches from cleaning surface.
IMPORTANT: Use soaps and chemicals that are
designed specifically for use with pressure washers. To
apply soaps/chemicals follow these steps:
• Prepare the soap/chemical as required by your job.
• Insert soap/chemical line into your container (soap/
chemicals and container not included).
• Slide the adjustable nozzle forward to low pressure
mode. Soap/chemicals cannot be applied with nozzle
in high pressure position.
• Review the use of the adjustable nozzle.
• Connect garden hose to water inlet (see “To Start Your
Pressure Washer" on page 9). Check that high
pressure hose is connected to spray gun and pump
{see Assembly), and start engine.
• Apply soap/chemicals to dry surface, starting from the
bottom and working up.
• Allow the soap/chemicals to soak in between 3-5
minutes before washing and rinsing.
• When rinsing on high pressure, start at lower portion
of area to be washed and work upward, using long,
even, overlapping strokes.
IMPORTANT: If you get spray nozzle too close,
especially on high pressure, you may damage the
surface you are cleaning.
