ENGINE
LUBRICATION
Use only high quality detergent oil rated with API service
classification SG-SL. 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, 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 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 starting the engine
and after each eight (8) hours of continuous use. Add SAE
30 motor oil or equivalent. Tighten oil filler plug securely
each time you check the oil level.
MAINTENANCE
TO CHANGE ENGINE OIL (See Fig. 13)
NOTE: Before tipping tiller to drain oil, empty fuel tank by
running engine until fuel tank is empty.
1. Disconnect spark plug wire from spark plug and place
wire where it cannot come in contact with plug.
2. Remove engine oil cap; lay aside on a clean surface.
3. Tip tiller on its side as shown and drain oil into a suitable
container. Rock tiller back and forth to remove any oil
trapped inside of engine.
4. Wipe off any spilled oil from tiller or side of engine.
5. Slowly pour oil down the oil fill spout, stopping every
few ounces to check the oil level with the dipstick.
6. Stop adding oil when you reach the FULL mark on the
dipstick. Wait a minute to allow oil to settle.
7. Continue adding small amounts of oil, rechecking the
dipstick until oil level settles at FULL. DO NOT over-
fill, or engine will smoke heavily from the muffler on
startup.
8. Always be sure to retighten oil dipstick before starting
