SERVICING YOUR ENGINE

THE IMPORTANCE OF MAINTENANCE
Good maintenance is essential for safe, economical and trouble-free
operation. It will also help reduce pollution.
Failure to properly maintain this engine, or failing to correct
a problem before operation, could result in a significant
malfunction.
Some malfunctions can cause seriously injuries or death.
Always follow the inspection and maintenance
recommendations and schedules in this owner's manual.
To help you properly care for your engine, the following pages include a
maintenance schedule, routine inspection procedures, and simple
maintenance procedures using basic hand tools. Other service tasks that
are more difficult, or require special tools, are best handled by
professionals and are normally performed by a Honda technician or other
qualified mechanic.
The maintenance schedule applies to normal operating conditions. If you
operate your engine under severe conditions, such as sustained high-
load or high-temperature operation, or use in unusually wet or dusty
conditions, consult your Honda servicing dealer for recommendations
applicable to your individual needs and use.
Maintenance, replacement, or repair of the emission control devices
and systems may be performed by any engine repair establishment
or individual, using parts that are ''certified'' to EPA standards.

MAINTENANCE SAFETY

Some of the most important safety precautions follow. However, we
cannot warn you of every conceivable hazard that can arise in
performing maintenance. Only you can decide whether or not you
should perform a given task.
Improper maintenance can cause an unsafe condition.
Failure to properly follow maintenance instructions and
precautions can cause serious injuries or death.
Always follow the procedures and precautions in this
owner's manual.

SAFETY PRECAUTIONS

• Make sure the engine is off before you begin any maintenance or
repairs. To prevent unintentional 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.
