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.
–
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.
