Good maintenance is essential for safe, 
economical, and trouble-free operation. It will 
also help reduce air pollution.

To help you properly care for your trimmer, 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 trimmer 
under severe conditions, such as sustained high-
load or high-temperature operation, or use it in 
unusually wet or dusty conditions, consult your 
authorized Honda servicing dealer for 
recommendations applicable to your individual 
needs and use.

Remember that your authorized Honda servicing 
dealer knows your trimmer 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.

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.
