Regular maintenance will improve the performance and
extend the life of the generator. See any authorized dealer

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.
All service and adjustments should be made at least once

last longer. Follow requirements in
