Safety Precautions; Maintenance Schedule - Honda GX25 Mode D'emploi

SAFETY PRECAUTIONS

• Make sure the engine is off before you begin any maintenance or
repairs. To prevent accidental startup, disconnect the spark plug
cap. This will eliminate several potential hazards:
– Carbon monoxide poisoning from engine exhaust.
Operate outside, away from open windows or doors.
– 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 non-flammable solvent, not
gasoline, to clean parts. Keep cigarettes, sparks and flames away
from all fuel related parts.
Remember that an authorized Honda servicing dealer knows your
engine best and is fully equipped to maintain and repair it.
To ensure the best quality and reliability, use only new Honda
Genuine parts or their equivalents for repair and replacement.
