Safety Precautions
• Make sure the engine is off before you begin any maintenance or
repairs. This will eliminate several potential hazards:
– Carbon monoxide poisoning from engine exhaust.
Be sure there is adequate ventilation whenever you operate
the engine.
– Burns from hot parts.
Let the engine and exhaust system cool before touching.

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

from all fuel-related parts.
