oil recommendations
We recommend the use of Briggs & Stratton Warranty Certified oils for best
performance. Other high-quality detergent oils are acceptable if classified for service
SF, SG, SH, SJ or higher. DO NOT use special additives.
Outdoor temperatures determine the proper oil viscosity for the engine. Use the chart
to select the best viscosity for the outdoor temperature range expected.
* Below 4°C (40°F) the use of SAE 30 will result in hard starting.
** Above 27°C (80°F) the use of 10W30 may cause increased oil consumption. Check
oil level more frequently.
checking oil Level

Oil level should be checked prior to each use or at least every 8 hours of operation.
Keep oil level maintained.
1. Make sure pressure washer is on a level surface.
2. Remove oil dipstick and wipe dipstick with clean cloth. Replace and tighten
dipstick. Remove and check oil level.
3. Verify oil is at Full mark (top hole) (
a
) on dipstick. Replace and tighten dipstick.
adding engine oil
1. Make sure pressure washer is on a level surface.
2. Check oil level as described in
Checking Oil Level
.
3. If needed, slowly pour oil into oil fill opening to the Full mark (top hole) on
dipstick. DO NOT overfill.
NOTICE
Overfilling with oil could cause the engine to not start, or hard starting.
• DO NOT overfill.
• If over the Full mark on dipstick, drain oil to reduce oil level to Full mark on dipstick.
4. Replace and tighten dipstick.
changing engine oil
If you are using your pressure washer under extremely dirty or dusty conditions, or in
extremely hot weather, change the oil more often.
KEEP OUT OF REACH OF CHILDREN. DON’T POLLUTE. CONSERVE
RESOURCES. RETURN USED OIL TO COLLECTION CENTERS.
change the oil while the engine is still warm from running, as follows:
1. Drain fuel tank by running pressure washer until fuel tank is empty.
2. Disconnect spark plug wire and keep it away from spark plug.
3. Clean area around oil fill, remove oil fill cap/dipstick. Wipe dipstick clean.
4. Tip your pressure washer to drain oil from oil fill into a suitable container
making sure you tip your unit away from spark plug. When crankcase is empty,
return pressure washer to upright position.
5. Repeat steps 3 and 4 to add engine oil as described in
Adding Engine Oil
.
6. Wipe up any remaining oil.
7. Reconnect spark plug wire to spark plug.
service air cleaner

Your engine will not run properly and may be damaged if you run it with a dirty air
cleaner. Service more often if operating under dirty or dusty conditions.
to service the air cleaner, follow these steps:
1. Remove screw (
a
).
2. Carefully remove air cleaner assembly to prevent debris from falling into
carburetor.
3. Take air cleaner assembly apart and clean all parts. Wash foam air cleaner (

)
in liquid detergent and water. Squeeze dry in a clean cloth.
4. SATURATE foam air cleaner in engine oil and squeeze in a clean cloth to
remove excess oil.
5. Reinstall clean or new foam air cleaner in base (
c
).
6. Install air cleaner securely on carburetor with screw.
service spark Plug

Changing the spark plug will help your engine to start easier and run better.
1. Clean area around spark plug.
2. Remove and inspect spark plug.
3. Replace spark plug if electrodes are pitted, burned or porcelain is cracked. Use
the recommended replacement plug. See
Specifications
.
4. Check electrode gap with wire feeler gauge and reset spark plug gap to
recommended gap if necessary (see
Specifications
).
5. Install spark plug and tighten firmly.
inspect Muffler and spark arrester
Inspect the muffler for cracks, corrosion, or other damage. Remove the spark arrester,
if equipped, and inspect for damage or carbon blockage. If replacement parts are
required, make sure to use only original equipment replacement parts.
air cooling system

Over time debris may accumulate in cylinder cooling fins and cannot be observed
without partial engine disassembly. For this reason, we recommend you have an
authorized Briggs & Stratton service dealer clean the cooling system per recommended
intervals (see
Maintenance Schedule
in beginning of
Maintenance
section). Equally
important is to keep top of engine free from debris. See
Clean Debris
.
carburetor adjustment
The carburetor on this engine is low emission. It is equipped with a non-adjustable idle
mixture valve. Top speed has been set at the factory. If adjustment is required, see an
authorized service dealer.
after each use
Water should not remain in the unit for long periods of time. Sediments or minerals
can deposit on pump parts and freeze pump action. Follow these procedures after
every use:
1. Shut off engine, turn off water supply, point gun in a safe direction, press red
button and squeeze trigger to relieve trapped pressure, and let engine cool.

caution
Avoid prolonged or repeated skin contact with used motor oil.
• Used motor oil has been shown to cause skin cancer in certain laboratory
animals.
• Thoroughly wash exposed areas with soap and water.
warning
Exhaust heat/gases could ignite combustibles, structures or
damage fuel tank causing a fire, resulting in death, serious
injury and/or property damage.
Contact with muffler area could cause burns resulting in
serious injury.
• DO NOT touch hot parts and AVOID hot exhaust gases.
• Allow equipment to cool before touching.
• Keep at least 1.5 m (5 ft.) of clearance on all sides of pressure washer including
overhead.
• Contact the original equipment manufacturer, retailer, or dealer to obtain a spark
arrester designed for the exhaust system installed on this engine.
• Replacement parts must be the same and installed in the same position as the
original parts.
caution
Excessively high operating speeds could result in minor injury
and/or pressure washer damage.
Excessively low speeds impose a heavy load.
• DO NOT tamper with governor spring, links or other parts to increase engine
speed. Pressure washer supplies correct rated pressure and flow when running at
governed speed.
• DO NOT modify pressure washer in any way.
