NOTE: Although mu It!-viscosity oils (5W-30,10W-30, etc,)
improve starting in cold weather, these multi-viscosity oils
will resuit in Increased oii consumption when used above
32°F (O^’C). Check yout engine oil level more frequently to
avoid possible engine damage from running low on oil.
Change the oii after the first two hours of operation and
every 25 hours thereafter 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.
TO CHANGE ENGINE OIL (See Figs. 16 and 17)
Determine temperature range expected before oil change.
All oil must meet API service classification SF or SG
= 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.
» Remove drain plug.
“ Tip tiller forward to drain oil.
» After oil has drained completely, replace oil drain plug
