It is recommendedthat you changethe motor oil after every 10 hours of operation and even sooner when operating in extremely dirty or dusty conditions. Refer
to the separateEngineOwner'sManual for detailed service instructions.
A. To Checkthe EngineOil Level:
1.Move the tiller to a levelareaand shut
off the engine.
2.Levelthe engineby adjusting the Depth Regulator Lever. The tines must be in contact with the ground. Move the Anti- ReverseStake backif necessary.

5.Onengines with a dipstick, removeit, wipe it clean, and reinstall it
Add oil (if required) to bring the levelto the FULLmark. Do not overfill.
B. To Changethe Engine Oil:
Changethe engine oil as instructed in the separateEngineOwner'sManual.
