1. Maintain the oil level between the mark (L) and the
mark (H) on the engine oil level gauge (dipstick).
Do not fill the crankcase above the (H).
NOTICE
The oil level checked that falls in the crosshatched (
Position "A" ) area between the (H) and below the
warning triangle ( Position "B" ) is safe for engine
operation.
Operating your engine when the oil level is the in
warning triangle area ( Position "B" ) above cross-
hatched section ( Position "A" ) could cause your
crankshaft to dip into the oil. The air bubbles created
from the crankshaft dipping into the oil reduces the
oils lubricating characteristics and could result in the
loss of power.
2. Remove the oil filler cap and add oil, if necessary.
3. Clean the oil filler cap. Install the oil filler cap.
4. If necessary, drain a small quantity of oil from the
crankcase to reduce the oil level. The oil level
needs to be between the mark (L) and the mark
(H) before operating the engine. Refer to the
"Operation and Maintenance Manual", Engine Oil
and Filter – Change, "Drain the Engine Lubricating
Oil" for more information.
After Operating the Engine

Note: Before checking the oil level, the engine must
have been switched off for a minimum of 30 minutes
to allow the oil to drain down to the crankcase.

1. Check the oil level and maintain the oil level
between the mark (L) and the mark (H) on the
engine oil level gauge (dipstick). Do not fill the
crankcase above the mark (H).
2. If necessary, remove the oil filler cap and add oil.
Note: When the oil level is shown to be at the (L)
mark, 1 L (0.3 US gal) of oil added will bring up the
oil level within the (L) and (H) marks.
3. Clean the oil filler cap and install the oil filler cap.
