The
generator's drive
belt
is located
under
the engine and is accessed by removing the cover as
shown in the illustration above. Drive belt tension is
adjusted at the factory with a spring length
of
1 inch (1.00").

this re-adjustment at the 50 hour break-in is very important
with regards to drive belt service life. Failure to perform the
re-adjustment can result in premature drive belt failure .and
possible warranty denial on belt replacement. Reference
Service Bulletin #276 dated May 6,
2015. Follow the
recommended inspection/adjustment periods found in the
