THE IMPORTANCE OF MAINTENANCE

Protect yourself and your equipment by properly maintaining your engine.
Proper engine maintenance is necessary for safe, economical, and trouble-free operation.
WARNING
Improperly maintaining this engine, or failure to correct a problem before operation, can cause a
malfunction in which you can be seriously hurt or killed. Always follow the inspection and maintenance
recommendations and schedules in this owner's manual.
To assist you in properly caring for your engine, the following pages include routine inspection procedures and simple maintenance
procedures using basic hand tools. Service tasks that are more difficult or which require special tools should be handled by
professionals and are normally performed by a service technician or qualified mechanic.
• NOTICE
See Maintenance Schedule for normal and extreme operation condition differences.

MAINTENANCE SAFETY INSTRUCTIONS

This manual contains very important safety precautions. However, we cannot warn you of every conceivable hazard that can arise
while performing maintenance. You must decide whether or not you should perform a given task and always be safety conscious.

Safety Precautions

• Make sure the engine is not running, is turned OFF, spark plug cap is removed from spark plug,
and engine is cooled off before you begin any maintenance or repairs. This can prevent several
potential hazards, such as the following:
Carbon monoxide poisoning from engine exhaust.
Run engine in a well-ventilated area.
Burns from hot parts.
Let the engine and exhaust system cool-off before touching. (see drawing right)
Injury from moving parts.
Do not run the engine unless instructed to do so.
• Before you begin maintenance, read all instructions and make sure you have the tools and skills required.
• To reduce the possibility of fire or explosion, be alert 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.
• It is suggested to keep a fire extinguisher close by when performing maintenance.
Your servicing dealer knows your engine best and is equipped to maintain and repair it.
