TO CHANGE ENGINE OIL (See Figs. 16 and 17)
Determine temperature range expected before oil change.
All oil must meet API service classification SF-SJ.
• Be sure tiller is on level surface.
• Oil will drain more freely when warm.
• Use a funnel to prevent oil spill on tiller, and catch oil in
a suitable container.

ENGINE
LUBRICATION
Use only high quality detergent oil rated with API service
classification SF-SJ. Select the oil’s SAE viscosity 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.

Service air cleaner more often under dusty conditions.
• Remove cover screw and cover.
TO SERVICE PRE-CLEANER
• Remove foam pre-cleaner from air cleaner cover.
• Wash it in liquid detergent and water.
