For best results, pump oil designed specifically for
pressure washers is recommended, as these contain a
rust inhibitor and an anti-foaming agent. If this oil is not
available, an SAE 15W-40 oil may be used.

Important Safety Instructions
DANGER: Carbon Monoxide. Using an engine indoors can kill
you in minutes. Engine exhaust contains high levels of carbon
monoxide (CO), a poisonous gas you cannot see or smell. You
may be breathing CO even if you do not smell engine exhaust.
WARNING: This product and its exhaust contain chemicals
known to the State of California to cause cancer, and birth
defects and other reproductive harm.
 NEVER use an engine inside homes, garages, crawlspaces or
other partly enclosed areas. Deadly levels of carbon monoxide can
build up in these areas. Using a fan or opening windows and doors
does NOT supply enough fresh air.
 ONLY use outdoors and far away from open windows, doors and
vents. These openings can pull in engine exhaust.

home. ALWAYS use a battery-powered or battery backup CO
alarm in your house. Read and follow all directions for CO
alarm before using. If you feel sick, dizzy or weak at anytime,
move to fresh air immediately. See a doctor. You could have carbon
monoxide poisoning.

WARNING: Do not operate this unit until you read this instruction
manual and the engine instruction manual for safety, operation and
maintenance instructions.
WARNING: When using this product basic precautions should
always be followed, including the following:
1. Read all instructions before using the product.
2. To reduce the risk of injury, close supervision is necessary when a
product is used near children.
3. Know how to stop the product and bleed pressures quickly. Be
thoroughly familiar with the controls.
4. Stay alert–watch what you are doing.
5. Do not operate the product when fatigued or under the influence of
alcohol or drugs.
6. Keep operating area clear of all persons.
7. Do not overreach or stand on unstable support. Keep good
footing and balance at all times.
8. Follow the maintenance instructions specified in the manual.
DANGER: RISK OF INJECTION OR SEVERE INJURY. KEEP
CLEAR OF NOZZLE. DO NOT DIRECT DISCHARGE STREAM
AT PERSONS. THIS PRODUCT IS TO BE USED ONLY BY
TRAINED OPERATORS.
WARNING: This product may not be equipped with a spark-
arresting muffler. If the product is not equipped and will be used
around flammable materials or on land covered with materials such
as agricultural crops, forest, brush, grass or other similar items,
then an approved spark arrester must be installed and is legally
required in the state of California. It is a violation of California statutes
section 130050 and/or sections 4442 and 4443 of the California
Public Resources Code, unless the engine is equipped with a spark
arrester, as defined in section 4442, and maintained in effective
working order. Spark arresters are also required on some U.S. Forest
Service land and may also be legally required under other statutes and
ordinances.
WARNING: This product and its exhaust contain chemicals
known to the State of California to cause cancer, and birth
defects or other reproductive harm. In addition, some cleaning
products and dust contain chemicals known to the State
of California to cause cancer, and birth defects or other
reproductive harm. Wash hands after handling.

OPERATION
Pressure Adjustments
The pressure setting is preset at the factory to achieve optimum
pressure and cleaning. To lower the pressure, follow these instructions.
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. Change to the 40˚ nozzle (white). This nozzle delivers a less
powerful stream of water and a wider spray pattern. Refer to
Spray Wand Nozzles.
NOTICE: DO NOT attempt to increase pump pressure. A higher
pressure setting than the factory set pressure may damage the pump.
Spray Wand Nozzles (Fig. 1, 7)
The nozzles for the spray wand are stored in the nozzle holder (B) on the
panel assembly (A). Colors on the panel identify nozzle location and spray
pattern. Refer to the following chart to choose the correct nozzle for
the job to be performed.

Pump (Fig. 19)
NOTE: The Pump was filled with oil at the factory. The preferred oil is
SIMPSON®Premium Pump Crankcase Oil. If this oil is not available,
an SAE 15W-40 oil may be used. Change the pump oil after the
first 50 hours of operation and every 100 hours thereafter, or every
3months.
TO CHECK OIL
The oil level should come to the dot in the middle of the sight glass
(AA).
HOW TO CHANGE PUMP OIL
1. Loosen pump oil fill plug (BB).
2. Place a container under the pump oil drain plug (CC).
3. Remove pump oil drain plug.
4. After oil is drained, replace pump oil drain plug. Tighten securely.

clogged or restricted, the pump pressure will pulsate. Clean the
nozzle immediately using the nozzle kit supplied and the following
instructions:
1. Shut off the pressure washer and turn off the water supply.
2. Pull trigger on gun handle to relieve any water pressure.
3. Disconnect the spray wand from the gun.
