CAUTION
Do not run the engine with a high or low 
oil level as this can cause engine dam-
age.

the engine, please refer to the engine 
manual included with the unit.

STEP 1:
Check oil level. Oil level should al-
ways be between the “FULL” and 
“ADD” marks on the dipstick.
Be sure the machine is level when 
checking the oil level. (Refer to the 
engine’s operating manual for sea-
sonal grades.).
We recommend that the oil be 
changed after the first 5 hours of 
use, then once every 50 hours.
