ASSEMBLY INSTRUCTIONS
Pressure Hose, Trigger Gun and Wand:
Install the pressure hose on the pressure washer as
shown in illustration.
Assemble wand components as shown below.
INSTALLATION
Place machine in a convenient location providing ample
support, drainage and room for maintenance.
IMPORTANT: Proper initial installation of equipment
will assure more satisfactory performance, longer
service life, and lower maintenance cost.
IMPORTANT:The use of a backflow preventer on the
water supply hose is recommended and may be re-
quired by local code.
Location:
The location should protect the machine from damag-
ing environmental conditions, such as wind, rain, and
freezing.
This machine should be run on a level surface where it
is not readily influenced by outside sources such as
strong winds, freezing temperatures, rain, etc. It should
be located to allow accessibility for refilling of fuel, ad-
justments and maintenance. Normal precautions should
be taken by the operator of the machine to prevent mois-
ture from reaching the electrical controls.
It is recommended that a partition be made between the
wash area and the machine to prevent water spray from
coming in contact with the machine. Excess moisture
reaching any electrical components or electrical controls
will reduce machine life and may cause electrical shorts.
Avoid small locations or areas near exhaust fans.
In addition, the pressure washer should never be oper-
ated in an enclosed area where high ambient tempera-
tures exist. High ambient temperatures (above 100°F)
can cause engine oil failure and will greatly reduce the
engine's performance.

OPERATING INSTRUCTIONS
1. Read all manuals provided with this pressure washer.
Become familiar with location and function of all op-
erating and safety controls.
WARNING: Check hoses, fittings, wand, trigger gun
and fuel connections daily for signs of wear, cracks
and looseness, and replace as required.
2. Connect water supply hose to the garden hose con-
nector located on pump. The water faucet and sup-
ply hose must be capable of providing a minimum of
3.0 gallons per minute.
WARNING: Do not fill engine fuel tank while engine
is running or hot. Let engine cool before refueling
or spontaneous fire may result. Fuel spillage or va-
pors could ignite if engine is hot.
3. Fill the engine fuel tank. It may be necessary to use
a funnel or long spout to clear the chassis if filling
with a gas can. Do not overfill, fill to the bottom of
filler neck only. Use lead free gasoline minimum 86
octane. Do not use gasoline containing more than
5% methanol, 10% ethanol or 15% MTBE. Refer
to the provided gasoline engine manual for additional
details.
4. Check pump and engine oil levels.
IMPORTANT: Before installing pressure nozzle on
initial start-up, turn on the water supply and allow
water to run from the end of the wand until clear to
prevent the nozzle from clogging.
IMPORTANT: If the pressure washer has not been
used for an extended period of time, remove the pres-
sure nozzle from the end of the wand and turn on
water supply. Allow water to run from the end of the
wand until clear.
5. Install the proper pressure nozzle for your cleaning
needs on end of wand. Refer to illustration below.
IMPORTANT: The trigger gun provided with this pres-
sure washer is equipped with a manual trigger lock
to prevent accidental operation of the trigger gun.
The trigger lock should be used whenever the trig-
ger gun is not in use.
To Start:
IMPORTANT: The water must be turned on before
starting. Running the pump dry will cause damage
and void warranty.
IMPORTANT: Do not allow machine to run with trig-
ger of the trigger gun released for more than 10 min-
utes at any one time or damage to pump may occur.
1. Turn on water supply.
2. Hold wand firmly, release trigger of trigger gun.
3. Place engine ON/OFF switch to ON position.
4. Turn fuel shut-off valve to ON position (if so
equipped). Move choke lever to full choke position
(choke may not be needed on warm engine). Move
throttle lever to half throttle position.
5. Pull the rope starter slowly until resistance is felt,
then pull briskly. Do not allow the rope starter to snap
back against the engine. Return it gently to prevent
damage to the starter.
6. When the engine starts, move choke lever until en-
gine runs smoothly. Move throttle lever to full throttle
position. When engine warms, move choke lever to
"no choke" position.
NOTE: If engine fails to start, refer to Troubleshoot-
ing Guide.

WASHING PROCEDURES
WARNING: Some detergents may
be harmful if inhaled or ingested,
causing severe nausea, fainting
or poisoning. The harmful ele-
ments may cause property dam-
age or severe injury.
DANGER: Do not place hands or
fingers in front of high pressure
spray. Bodily injury may result.
1. Test pressure and spray pattern on hard surface (i.e.
cement) to gauge distance and impact of water spray.
2. If detergents are to be used, only use detergents
intended for pressure washers. Follow instructions
on the detergent container.
3. Wash from the bottom to the top, using side to side
motions. This washes away heavy dirt and allows
the detergent to soak as you work toward the top.
4. Do not wash at a 90oangle to the work (straight at
it). This will allow water to splash back at you and
reduces your cleaning power. Wash at a 30oto 60o
angle to the work.This will allow the water to splash
away from you and the water will wash the dirt away
faster and easier.
5. Use the full width of the spray pattern to wash in
a wide path. Overlap spray paths for complete
coverage.Wash from side to side, using slow, steady
motions.
6. The nozzle should be 12" to 24" from the work, closer
for tough areas. Be careful on painted or delicate
surfaces, the pressure may damage surface if nozzle
is too close.
7. Small parts should be washed in a basket so the
pressure does not push them away. Larger, light-
weight parts should be clamped down so the pres-
sure does not push them away.
NOTE: If pressure washer is running and not being
used for more than 2 minutes, turn off engine.
SHUTDOWN PROCEDURES
1. Move throttle lever to idle position.
2. Turn engine ON/OFF switch to the OFF position.
3. Turn fuel shut-off valve to OFF position (if so
equipped).
4. Turn water supply off.
CAUTION: Do not allow pump to run without water.
5. Squeeze trigger of trigger gun to relieve system
pressure.
STORAGE
DANGER: Do not store flammable
liquids (gasoline, diesel fuel, sol-
vents, etc.) near pressure washer,
or in non-ventilated areas.
Protect from freezing by storing in
a heated area, or by flushing the
system with antifreeze (use an
automotive engine antifreeze or
windshield washer solvent to anti-
freeze).To flush the system with an-
tifreeze, the following steps are to be followed:
1. Attach a short length of hose to the garden hose
connector located on the pump.
2. Place the other end of the hose into a container of
antifreeze.
3. Start engine and allow to run until antifreeze flows
from the end of the wand.
4. Squeeze and release the trigger of the trigger gun
several times to antifreeze the unloader system.
5. Release the trigger of the trigger gun. Stop engine.
6. Squeeze the trigger of the trigger gun to relieve sys-
tem pressure.
If the pressure washer is not to be used for an extended
length of time, it is recommended that the system be
flushed with antifreeze for rust protection. Refer to the
Gasoline Engine Manual for engine storage information.
MAINTENANCE & SERVICE
WARNING: Unauthorized machine modification or
use of non-approved replacement parts may cause
personal injury and/or property damage and will void
the manufacturer warranty.
