MAINTENANCE
The Importance of Maintenance.
Good maintenance is essential for safe, economical, and trouble-free operation. It will also help
reduce air pollution.
Improper maintenance, or failure to correct a problem before operation, can cause a malfunction in
which you can be seriously injured or killed.
Always follow the inspection and maintenance recommendations and schedules in this instruction
manual.
Maintenance Safety
Make sure the engine is off before you begin any maintenance or repairs.
Let the engine and exhaust system cool before touching.
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.
Maintenance Schedule
Remember that this schedule is based on the assumption that your machine will be used for its
designed purpose. Sustained high-load or high-temperature operation, or use in unusually wet or dusty
conditions, will require more frequent service.
