STOPPING THE ENGINE

To stop the engine in an emergency, simply turn the engine switch to the 
OFF position. Under normal conditions, use the following procedure.

1. Move the throttle lever to the MIN. position.

Some engine applications use a remote-mounted throttle control 
rather than the engine-mounted throttle lever shown here.

2. Turn the engine switch to the OFF position.

3. Turn the fuel valve lever to the OFF position.

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 Honda 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. To prevent unintentional startup, disconnect the spark plug 
cap. This will eliminate several potential hazards:

Carbon monoxide poisoning from engine exhaust. 

Operate outside, away from open windows or doors.

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 non-flammable 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 Honda Genuine 
parts or their equivalents for repair and replacement.
