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.
* B elow 4°C (40°F) the use of SAE 30 will result in hard starting.
** A bove 27°C (80°F) the use of 10W30 may cause increased oil consumption. Check
oil level more frequently.

cleaner. Service more often if operating under dirty or dusty conditions.
to service the air cleaner, follow these steps:
1. Remove the knob (a) and air filter cover (B).
2. Lift the cartridge (c) off of the base (d).
3. Remove the pre-cleaner (e) from the cartridge. Discard the old cartridge.
4. Wash the pre-cleaner in liquid detergent and water.
5. Let the pre-cleaner thoroughly air dry. DO NOT oil the pre-cleaner.
6. Assemble the pre-cleaner onto the new cartridge.
7. Install the new cartridge and pre-cleaner into the base and onto stud (F). Make

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.
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.

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.
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.
