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.

TO CHANGE ENGINE OIL (See Figs. 16 and 17)

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.

Use a funnel to prevent oil spill on tiller, and catch oil in a suitable container.

Remove drain plug. For easier removal of plug use 7/16 12 Pt. socket with extension.)

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.
