MAINTENANCE

Moving parts can amputate fingers or cause severe injuries. 
Keep hands, clothing and loose objects away from all openings. 
Always stop engine, disconnect spark plug, and make sure all 
moving parts have come to a complete stop before removing 
obstructions, clearing debris, or servicing unit. Allow unit to 
cool before performing service. Wear gloves to protect hands 
from sharp edges and hot surfaces.

Operating a poorly maintained unit can result in serious injuries 
to operator or bystanders. Always follow all maintenance 
instructions as written, otherwise serious personal injury can 
result. 

Your unit is designed to provide many hours of trouble free service. Regular 
scheduled maintenance will help your unit achieve that goal. If you are 
unsure or are not equipped with the necessary tools, we recommend that 
you take your unit to a Servicing Dealer for maintenance. To help you 
decide whether you want to DO-IT-YOURSELF or have the Dealer do it, 
each maintenance task has been graded. If the task is not listed, see your 
Dealer for repairs.

The use of emission control components other than those specifically 
designed for this unit is a violation of federal law. 

Skill Levels

Level 1

 = Easy to do. Common tools may be required.

Level 2

 = Moderate difficulty. Some specialized tools may be required.
