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
32°F (0°C). Check your engine oil level more frequently to
avoid possible engine damage from running low on oil.
Change the oil after every 50 hours of operation or at least
once a year if the tiller is not used for 50 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.
TO CHANGE ENGINE OIL (See Figs. 11 and 12)
Determine temperature range expected before oil change.
All oil must meet API service classification SG-SL.
• Ensure tiller is on level surface.
• Oil will drain more freely when warm.
• Catch oil in a suitable container.
• Remove drain plug.
• Tip tiller forward to drain oil.

Wash and clean the urethane foam with detergent. After
cleaning, dry it. Clean the urethane foam element every
50 hours.
