LUBRICATION

Use only high quality detergent oil rated with API service classification SF, SG or SH. Select the oil'sSAE viscosity grade according to your expected temperature.

TEMPERATURE RANGE ANI"_IPATED BEFORE NEXT OIL CHANGE

NOTE: Although multi-viscosityoils (5Wo

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 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 start- ing the engine and after each five (5) hours of continuous use. Add SAE 30 motor oil or equivalent. Tighten oil t;ller

plug securely each time you check the oil level.

TO CHANGE ENGINE OIL

Determine temperature range expected before oil change. All oil must meet API service classification SF, SG or SH.

•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 oil drain plug. Be careful not to allow dirt to enter the engine. For easier removal of plug use 7/16 12 Pt. socket with extension.

•"rip tiller forward to drain oil.

•After oil h_s drained completely, replace oil drain plug and tighten securely.

•RemOve oil fill plug.

•Refill engine with oil through oil fill tube. See "CHECK ENGINE OIL LEVEL" in the Operation section of this manual.

•Replace oil fill plug and tighten securely.
