release trigger and turn the safety latch
ON.
If you have any problems operating your pressure
washer, please call the pressure washer helpline at
1-800-270-1408.
Safety Latch ON
You have assembled your high pressure washer and
have prepared the engine for starting. You are now
ready to clean your car, boat or the outside of a
building or whatever you plan to clean.
How to Start Your Engine
Note: This is a multi–position choke.
Note: For a warm engine, be sure the Throttle Control
Lever is in the ‘Fast’ position and the Choke Lever is
in the “Run” position.
The best way to start your engine–powered pressure
washer for the first time is to follow these instructions
step–by–step. This starting information also applies
whenever you start the engine after you have let the
pressure washer sit idle for at least a day.
• Grasp rope handle and pull slowly until you feel
some resistance. Then pull cord rapidly to
overcome compression, prevent kickback and start
the engine. Let rope return to starter slowly.
• This pressure washer requires a water source that
flows at least 2.5 gallons per minute. Do not
attempt to siphon water from a non–pressurized
container. Place the pressure washer close
enough to an outside water source so that no more
than 50' of garden hose is needed.
Note: Always keep the Throttle Control Lever in the
‘Fast’ position when operating the pressure washer.
• When the engine starts, gradually move the Choke
Lever from one position to the next until it is in the
“Run” position.
• Check that the high pressure hose is tightly
connected to the spray gun and to the pump. See
ASSEMBLY section for illustrations.
If after 3 pulls the engine fails to start, disengage the
spray gun safety latch, squeeze the trigger to relive
water pressure, re–engage the spray gun safety latch,
move the Choke Lever to the ‘Run’ position and pull
the recoil starter handle rapidly (Max. 3 pulls).
• Connect the garden hose to water inlet on the
pressure washer pump and turn the water on all
the way.
IMPORTANT: Do not run pump without the water
supply connected and turned on. You must follow this
caution or the pump will be damaged.
How to Stop Your Pressure
Washer
• Squeeze the trigger on the spray gun to relieve air
pressure caused by turning ON the water. Water
will spew out the gun in a thin stream. Continue to
hold trigger until you have a steady stream of water
and no air remains.This will make it easier to pull
start the engine. Release the trigger.
• Move the Throttle Control Lever to the ‘Slow’ position.
• Wait for the engine to idle down.
• Move the Throttle Lever Lever to the ‘Stop’ position.
• Simply shutting off the engine will not release
pressure in the system. Squeeze trigger on the
spray gun to relieve pressure in the hose.
• Apply the safety latch to the spray gun trigger
(Figure 10).
Note: A small amount of water will squirt out when
you release the pressure.
• Move the Throttle Control Lever to the ‘Fast’
position.
• Set Choke Lever to “Choke” position.

How to Use the Adjustable
Nozzle and Adjust Pressure
Figure 12 — Pressure control knob.
Pressure Control Knob
You now should know how to START your pressure
washer and how to STOP it. The information in this
section will tell you how to adjust the spray pattern
and apply detergent or any other cleaning chemicals.
DANGER! Never adjust spray pattern when
spraying. Never put hands in front of nozzle to
adjust spray pattern.
On the end of your spray gun is a nozzle that you can
slide forward and backward and that you can also
twist from side to side. With the adjustable nozzle you
can adjust the spray pattern to be 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.
• Point the nozzle toward the ground and press the
trigger to test the pattern.
• Twisting the nozzle adjusts the spray pattern from a
narrow pattern to a fan pattern.
• For most effective cleaning, keep spray nozzle
between 8 to 24 inches away from cleaning
surface.
• Slide the nozzle forward when you wish to adjust
the spray to low pressure mode (Figure 11). Slide
the nozzle backward to achieve high pressure.
• If you get the spray nozzle too close, especially
using high pressure mode, you may damage the
cleaning surface.
• Located on the side of the pump is a pressure
control knob. You can increase and decrease the
pressure of the spray by turning the knob clockwise
or counterclockwise respectively (Figure 12).
• Do not get closer than 6 inches when cleaning
automobile tires.

Applying Detergent with the
Adjustable Nozzle
CAUTION! Keep the plastic injector tube from
coming in contact with the hot muffler. When
inserting the filter into a cleaning agent bottle,
route the tube so as to keep it from
inadvertently contacting the hot muffler.
IMPORTANT: Use soaps designed specifically for
pressure washers. Household detergents could
damage the pump.
Note: After using chemical injection, you must flush
the hose and the pump with clear water to prevent
chemicals from drying and clogging the chemical
injection system. See “Cleaning Chemical Injector
System” on page 14.
IMPORTANT: You must attach all hoses before you
start the engine. Starting the engine without all the
hoses connected and without the water turned ON will
damage the pump.
To apply detergent follow these steps:
Pressure Washer Rinsing
• Review the use of adjustable nozzles on Page 11.
• Prepare the detergent solution as instructed.
WARNING! Be extremely careful if you must
• Hang the detergent solution on hook of the wireform
on the handle as shown (Figure 13).
use the pressure washer from a ladder,
scaffolding or any other unstable location.
Pressure in a running washer builds as you
climb. When you press the trigger, the recoil
from the initial spray could force you to fall.
The high pressure spray is also dangerous if
you are too close to the cleaning surface.
Figure 13 — Insert the small filter into container of
cleaning solution.
For Rinsing:
• Slide nozzle backward to high pressure, squeeze
trigger and wait for detergent to clear.
• Keep the spray gun a safe distance from the area
you plan to spray.
• Place small filter end of the chemical injecting tube
into the detergent container (Figure 13).
• Apply a high pressure spray to a small area and
then check the surface for damage. If no damage is
found, you can assume it is okay to continue
cleaning.
• Slide the adjustable nozzle forward to low pressure
mode. Detergent cannot be applied with nozzle in
high pressure position.
• Start at top of area to be rinsed, working down with
the same overlapping strokes used for cleaning.
IMPORTANT: Detergent cannot be applied without
the water source turned on.
Note: You can also stop detergent from flowing by
simply removing siphon from bottle.
• Make sure garden hose is connected to water inlet.
Check that high pressure hose is connected to
spray gun and pump, and start engine.
Automatic Cool Down System
(also called ‘Thermal Relief’)
If you run the engine on your pressure washer for 3–5
minutes without pressing the trigger on the spray gun,
circulating water in the pump can reach a temperature
between 140–145°F. When the water reaches this
temperature, the automatic cool down system
engages and cools the pump by discharging the
warm water onto the ground. This system prevents
internal damage to the pump.
• Apply detergent to a dry surface, starting from the
bottom and working up to avoid streaking.
• Allow the detergent to soak in for 3–5 minutes
before washing and rinsing. Reapply if necessary to
prevent drying.
• For washing, start at lower portion of area to be
washed and work upward, using long, even,
overlapping strokes.

GENERAL MAINTENANCE
RECOMMENDATIONS
DANGER! Water spraying from a leak is
capable of injecting material into skin. Inspect
hose each time before using it. Never repair a
high pressure hose. Replace it with another
hose that meets the maximum pressure rating
of your pressure washer.
The warranty of the high pressure washer does not
cover items that have been subjected to operator
abuse or negligence. To receive full value from the
warranty, operator must maintain high pressure
washer as instructed in this manual.
Check Detergent Hose
Examine the filter on the detergent hose and clean if
clogged. Hose should fit tightly on barbed fitting.
Examine hose for leaks or tears. Replace the filter or
hose if either is damaged.
• Some adjustments will need to be made periodically
to properly maintain your high pressure washer.
• All adjustments in the Service and Adjustments
section of the engine owner’s manual should be
made at least once each season.
Check Gun and Wand
• Once a year you should clean or replace the spark
plug and clean or replace the air filter and check the
gun and wand assembly for wear. A new spark plug
and clean air filter assure proper fuel–air mixture
and help your engine run better and last longer.
Examine hose connection to gun and make sure it is
secure. Test trigger by pressing it and making sure it
springs back into place when you release it. Put
safety latch in ON position and test trigger. You
should not be able to press trigger.
Before Each Use
Check In-Line Filter
• Check engine oil level.
Refer to Figure 14 and service the in-line filter if it
becomes clogged, as follows:
• Check water inlet screen for damage.
• Check high pressure hose for leaks.

Nozzle Maintenance
4. Place the o-ring into the recess. Push the o-ring
snugly against the in-line filter screen.
If the adjustable nozzle becomes restricted or clogged
with foreign materials, such as dirt, excessive pump
pressure may develop. If this nozzle becomes
partially clogged, it can cause a pulsing sensation
during use. This generally is not a pump related
problem, but rather a clogged or partially restricted
adjustable nozzle.
5. Assemble the lance to the spray gun, as described
earlier in this manual.
Purge Pump of Air and
Contaminants
To remove the air from the pump, follow these steps:
If the adjustable nozzle becomes clogged or partially
restricted, immediately clean the nozzle with the kit
included with your pressure washer by following these
instructions:
• Set up the pressure washer as described in the
ASSEMBLY section (starting on page 6) and
connect the water supply.
• Remove the wand extension from the gun.
• Shut off the engine and turn off the water supply.
• Squeeze the trigger on the gun and hold.
• Separate the nozzle extension from the gun.
To remove any contaminants from the pump, follow
these steps:
• Adjust the nozzle extension to the stream position.
• Remove nozzle from the end of the wand extension
(Figure 15) using a 2mm or 5/64 allen wrench (like
the one included in the kit).
• Set up the pressure washer as described in the
ASSEMBLY section, and connect the water supply.
• Remove the nozzle extension from the spray gun.
Figure 15 — Removing and cleaning the nozzle.
• Start the engine according to instructions in
OPERATION section.
• Squeeze the trigger on the spray gun and hold.
• When the water supply is steady and constant,
engage the safety latch and refasten the nozzle
