SERVICING YOUR SNOW 

BLOWER

Proper maintenance is essential for safe, economical, and 
trouble-free operation. It also helps reduce air pollution.  

To help you properly care for your snow blower, 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 snow blower under severe conditions, such as 
sustained high load, high temperature, or unusually wet conditions, 
consult your servicing dealer for recommendations applicable to your 
individual needs and use.
Remember that an authorized Honda servicing dealer knows your 
snow blower 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.

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.
