Maintenance Instructions LUBRICATION
3. Remove the dipstick and open oil drain valve,
and drain the oil into a suitable container. Be
sure to allow ample time for complete drainage.
4. Before removing the oil lter, clean the area
around the lter to keep dirt and debris out of the
engine.
5. Remove the old oil lter and wipe off the lter
mounting surface on the engine.

6. Apply a thin coating of new oil to the rubber gas-
ket on the replacement oil lter.
IMPORTANT: Use ONLY oil lters from the en-
gine manufacturer. Aftermarket oil lters may not
seal properly and/or may not have the cor rect
pressure relief valve for proper lubrication.
7. Install the new oil lter on the engine. Turn the
oil lter clockwise until the rubber gasket con tacts
the sealing surface, then tighten the lter an
additional 1/2 to 3/4 turn.
8. Close the oil drain valve and tighten until snug.
Do not overtighten.
9. Fill the crankcase with new, clean oil. Use only
crankcase lubricants recommended by the
engine manufacturer. Refer to Specications in
this manual or the engine owner’s manual. Use
the recommended oil viscosity for the expected
ambient temperature. Oil with the correct
viscosity will aid starting in cold weather and
assure proper lubrication in hot weather. Fill to
FULL mark on the dipstick; crankcase capacity
is 1.9 quarts (1.8 liters) when changing oil and
lter.
IMPORTANT: Check the dipstick reading before
adding the last 1/2 pint of oil and ll only to the
FULL mark. The oil level should never be over
the FULL mark on the dipstick; overlling can re-
sult in engine overheating and loss of power.
10. Start the engine and check for oil leaks around
the oil lter. Stop the engine, recheck the oil lev-
el, and add oil if necessary. (When the engine is
rst operated with a new oil lter, the oil level will
drop slightly as the lter is lled with oil.)
