General Recommendations
Regular maintenance will improve the performance and extend the life of the generator. See any
authorized dealer for service.
The generator's warranty does not cover items that have been subjected to operator abuse or
negligence. To receive full value from the warranty, the operator must maintain the generator as
instructed in this manual.
Some adjustments will need to be made periodically to properly maintain your generator.
All service and adjustments should be made at least once each season. Follow the requirements
in the Maintenance Schedule chart above.
Notice Once a year you should clean or replace the spark plug and replace the air filter. New
spark plugs and clean air filter assure proper fuel-air mixture and help your engine run better
and last longer.
