Spark Arrester Service

Your engine is not factory-equipped with a spark arrester. In some areas, it is illegal to operate an engine without a spark arrester. Check local laws and regulations. A spark arrester is available from your nearest qualified service center.The spark arrester must be serviced every 50 hours to keep it functioning as designed.

If the engine has been running, the muffler will be very hot. Allow the muffler to cool before servicing spark arrester.

WARNING

Contact with muffler area can result in serious burns.

Exhaust heat/gases can ignite combustibles, structures or damage fuel tank causing a fire.

•DO NOT touch hot parts and AVOID hot exhaust gases.

•Allow equipment to cool before touching.

•Keep at least 5 feet (1.5 m) of clearance on all sides of pressure washer including overhead.

•Code of Federal Regulation (CFR) Title 36 Parks, Forests, and Public Property require equipment powered by an internal combustion engine to have a spark arrester, maintained in effective working order, complying to USDA Forest service standard 5100-1C or later revision. In the State of California a spark arrester is required under section 4442 of the California Public resources code. Other states may have similar laws.

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 center 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.

Clean Combustion Chamber

We recommend you have an authorized Briggs & Stratton service center remove combustion deposits from the cylinder, cylinder head, top of piston and around valves per recommended intervals (see Maintenance Schedule in beginning of Maintenance section).
