the engine. Remove the drain plug and drain the oil. Use
an approved container to store used oil. Remove the oil
fill cap (2) (to aid in draining).

with a new oil filter (See service parts list). Apply a light
coat of oil to the seal of the filter.
3. Replace and tighten the oil drain plug (3) underneath
the engine.

fill. Place drain end of funnel down through the hole and
into the fill port as shown.
