Improper maintenance, 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 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.
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.
To ensure the best quality and reliability, use only new genuine
Honda parts or their equivalents for repair and replacement.
Remember that an authorized Honda servicing dealer knows your
engine best and is fully equipped to maintain and repair it.
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.
Read the instructions before you begin, and make sure you have
the tools and skills required.
Do not run the engine unless instructed to do so.
Let the engine and exhaust system cool before touching.
Be sure there is adequate ventilation whenever you operate
the engine.
Make sure the engine is off before you begin any maintenance
or repairs. This will eliminate several potential hazards:
Failure to properly follow maintenance instructions
and precautions can cause you to be seriously hurt or
killed.
Always follow the procedures and precautions in this
owner’s manual.
Internal vent carburetor with dual element type only.
Cyclone type every 6 months or 150 hours.

These items should be serviced by your Honda servicing
dealer, unless you have the proper tools and are mechanically
proficient. Refer to the Honda shop manual for service
procedures.
Service more frequently when used in dusty areas.
Good maintenance is essential for safe, economical and trouble-
free operation. It will also help reduce pollution.

proper maintenance intervals.
