ENGINE OIL AND FILTER CHANGE
IA wa r nIngI State and federal agencies have de¬
termined that contact with used engine oil can
cause cancer or reproductive toxicity. Take care
to limit skin contact and breathing of vapors as
much as possible. Use rubber gloves and wash
exposed skin.
Refer to Table 2 for scheduled oil change and filter
replacement. See Figure 2 on Page 3 for oil filter
and oil drain locations.
1. Run the engine until it is warm. Stop the engine
and disconnect the spark plug and, if so
equipped, the battery' (negative [-] cable).
[AwarningI Accidental starting of the en¬
gine can result in severe personal injury or
death,. Always disconnect the spark plug
and the battery (negative [-] cable) before
changing oil.
2. Remove the oil fill cap.
[Awarning I Crankcase pressure can blow
hot engine oil out the fill opening causing
severe burns. Always stop the engine be¬
fore removing the oil fill cap.
3. Place a pan under the oil drain opening and re¬
move the oil drain plug. Reinstall the plug se¬
curely after the oil has drained completely.
4. Spin off the oil filter canister, drain the oil and
discard the filter according to local regulations.
5. Thoroughly wipe off the filter mounting surface.
6 . Make sure the gasket is in place on the filter
canister and apply a thin film of oil to the gasket.
7. Spin on the new filter canister by hand until the
gasket just touches the mounting pad and then
turn it an additional 1/2 to 3/4 turn. Do not over¬
tighten.
8 . Refill with API Class SG or SH oil (also SG/CD,
SG/CE, SH/CD or SH/CE) having an SAE vis¬
cosity grade appropriate for the expected tem¬
peratures, as indicated by Table 1. See Specifi¬
cations for the oil capacity.
DO NOT FILL TO A LEVEL ABOVE THE FULL
MARK ON THE DIPSTICK. Drain the excess oil
if too much has been added.
IA caution I Too much oil can cause high oil
consumption, high operating temperatures
and oil foaming. Too little oil can cause se¬
vere engine damage. Keep the oil level be¬
tween the Full and Add marks on the dip¬
stick.
9. Reconnect the spark plug and battery.
10. Start the engine and run it for a short time while
checking for oil leaks around the drain plug and
oil filter. Do not overtighten: tighten only as nec¬
essary to eliminate leaks.
11. Used oil is harmful to the environment. Pourthe
used oil into a sealed container and deliver it to
the nearest recycling center.
