Servicing Your Trimmer; Maintenance Safety; Maintenance Schedule - Honda HHT25S Owner's Manual

SERVICING YOUR TRIMMER

Proper maintenance is essential for safe, economical, and
trouble-free operation. It also helps reduce air pollution.

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 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 in unusually wet or
dusty conditions, consult your servicing dealer for recommendations
applicable to your individual needs and use.
Remember that an 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, Honda
Genuine 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.

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.

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 manual.
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.
