TEMPERATURE RANGE ANTICIPATED BEFORE NEXT OIL CHANGE
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 op­
eration 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.
Determine temperature range expected
before oil change. All oil must meet API
service classification SG-SL.
• Be sure tiller is on level surface.
• Oil will drain more freely when warm.
• Catch oil in a suitable container.
1. Remove drain plug.
2. Tip tiller forward to drain oil.
3. After oil has drained completely,
replace oil drain plug and tighten se­
curely.
4. Remove oil filler plug. Be careful not
to allow dirt to enter the engine.
AIR CLEANER
Service air cleaner cartridge every
twenty-five hours, more often if engine is
used in very dusty conditions.
1. Loosen air cleaner screw(s).
2. Remove air cleaner cover.
3. Carefully remove air cleaner cartridge.
Be careful. Do not allow dirt or debris
to fall into carburetor.
4. Clean by tapping gently on a flat sur­
face.
NOTE: If very dirty or damaged, replace
cartridge.
