STEP 1:
Check engine oil level. Oil level should be level with the bottom of
the oil filler neck. Be sure the machine is level when checking the oil level.

recommend that the oil be changed after the first 5 hours of use, then once
every 50 hours.
NOTE:
Improper oil levels will cause low oil sensor to shut
off engine.
IMPORTANT! Do not run engine with high or low oil levels
as this will cause engine damage.
