SERVICING YOUR ENGINE
THE IMPORTANCE OF MAINTENANCE
Good maintenance is essential for safe, economical and trouble-free
operation. It will also help reduce pollution.
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 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.
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.
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 genuine Honda
parts or their equivalents for repair and replacement.
