8. SERVICING
8.1 SAFETY PRECAUTIONS
Make sure the engine is off before you begin any maintenance or repair. This will
eliminate several potential hazards:
ƽCarbon monoxide poisoning from engine exhaust.
Never run the machine indoors. The exhaust fumes contain carbon monoxide, a
very toxic gas.
ƽBurns from hot parts.
Let the engine cool and up to 30 minutes after use before touching.
ƽInjury from moving parts.
Read the instructions before you begin, and make sure you have the tools and skills
required.
To reduce the possibility of fire or explosion, be careful when working around
gasoline. Use only a nonflammable solvent, not gasoline, to clean parts. Keep
cigarettes, sparks and flames away from all fuel related parts.
