Do not touch hot muffler or cylinder fins as contact may cause burns.
TO CHANGE ENGINE OIL (See Figs. 19 and 20)
• Be sure tiller is on level surface.
• Oil will drain more freely when warm.

ENGINE
LUBRICATION
Use only high quality detergent oil rated with API service
classification SG-SL. Select the oil’s SAE vis cos i ty grade
according to your expected temperature.
NOTE:
Although multi-viscosity oils (5W-30, 10W-30, etc.)
improve starting in cold weather, these multi-viscosity oils
will result in increased oil consumption when used above
40°F (4°C). Check your engine oil level more frequently to
avoid possible engine damage from running low on oil.
Change the oil after every 25 hours of operation or at
least once a year if the tiller is not used for 25 hours in
one year.
Check the crankcase oil level before starting the engine
and after each five (5) hours of continuous use. Add SAE
30 motor oil or equivalent. Tighten oil filler plug securely
each time you check the oil level.
