NOTE: Althoughmulti-viscosity oils (5W-30, 10W-30, etc.)
improve starting in cold weather, these multi-viscosityoils
will rasult 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.
