jurisdictions may haves imilarlaws. Contact t heoriginal equipment
manufacturer,retailer, or dealer to obtain a spark arrester designed for the
exhaust systeminstalled on this engine.
Removeaccumulated debris frommuffler area and cylinder area. Inspect the muffler (A,
Figure5) for cracks, corrosion, orother damage. Remove the spark arrester (B), if
equipped, and inspect for damage or carbon blockage. If damage is found, install
replacement parts beforeoperating.
WARNING: Replacementparts must be of the same design and installed

How ToClean The Air Cooling System - Figure 7
Running engines produce heat. Engine parts, especially muffler,
becomeextremely hot.
Severethermal burns can occur on contact.
Combustibledebris, such as leaves, grass, brush, etc. cancatch fire.
WARNING
Allowmuffler, engine cylinder and fins to cool before touching.
Removeaccumulated debris frommuffler area and cylinder area.
NOTICE: Do not use water to clean the engine. Watercould contaminate the fuel
system.Use a brush or dry cloth to clean the engine.
This is anair cooled engine. Dirt or debris can restrict air flow and cause the engine to
overheat, resulting in poor performance and reduced engine life.
Usea brush or dry clothto remove debris fromthe finger guard (A). Keep linkage,
springs andcontrols ( B)clean. Keepthe area around and behind the muffler (C)freeof
any combustible debris (Figure 7). Make sure that the oil cooler fins (D) are free of dirt
