■FUEL FILTER (F13)

When the engine runs short of fuel supply, check the fuel strainer for blockage.

■WAY OF THE COOLING AIR (F14)

This engine is air-cooled. Dust clogging between the inlet port of the cooling air and cylinder fins will cause overheating of the engine. Periodically check and clean the cylinder fins after removing the air cleaner and the cylinder cover.

■SPARK PLUG (F15)

Starting failure and mis-firing are often caused by a fouled spark plug. Periodically clean the spark plug, and replace with a new one as required.

IMPORTANT

When dismounting the plug cap, be careful not to take off the seal from the plug cap. Operating the engine without seal may cause overheating of the engine.

IMPORTANT

When setting up the spark plug, screw it by your fingers at first, then tighten by using special plug wrench. Over tightening will damage the cylinder and piston.
