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.
－
Injury from moving parts.
Do not run the engine unless instructed to do so.
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.
