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.

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.

• 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.

(1) Service more frequently when used in dusty areas.
