MAINTENANCE AND CARE
Proper routine maintenance of your generator is essential for safe, economical, and trouble-free
operation. It will also help reduce air pollution.
Maintenance Schedule
Remember that this schedule is based on the assumption that your machine will be used for its
designed purpose. Sustained high-load, high temperature operation, or use in unusually wet or
dusty conditions, will require more frequent service.
WARNING: 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.
●
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.
