ENGINE
LUBRICATION
Use only high quality detergent oil rated with API service
classification SJ–SN. 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, they 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 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.
TO CHANGE ENGINE OIL (See Figs. 17 & 18)
Determine temperature range expected before oil change.
All oil must meet API service classification SJ–SN.
• 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 con tain er.
• Remove drain plug.
• Tip tiller forward to drain oil.
• After oil has drained completely, replace oil drain plug
and tighten securely.
• Remove oil filler plug. Be careful not to allow dirt to
enter the engine.
• Refill engine with oil. See "CHECK ENGINE OIL LEVEL "
in the Operation section of this manual.
