Replace Engine Oil
WARNING! The drain plug of the engine oil
pan is mounted at the cover under the control
lever. When draining engine oil, use
outriggers to raise the machine approximately
80 mm. Always place timbers beneath right
and left crawlers and ground for safety.
WARNING! Securely tighten the oil level
gauge after checking/refilling the oil.
If the oil level gauge falls during the operation,
the hot oil may spout out of the pan, causing
burns.
WARNING! Various parts are at elevated
temperatures immediately after engine
operation.
Do not proceed with oil or filter cartridge
replacement immediately but wait for the
engine to cool to the extent that you can touch
it with your hand.
CAUTION: Make sure that old packing is not
stuck to filter base. If it is, it can cause oil
leakage.
CAUTION: See “LUBRICATING OIL” on page
5-10 for the oil to be used.
Using oil other than those specified may
shorten the life of the engine. Be sure to refill
the specified oil.
CAUTION: Keep the engine oil at an
appropriate level.
CAUTION: When the engine is cold, oil cannot
be drained completely.
Drain the oil in a condition in which the engine
cools down to the extent that it is touchable by
hands.
CAUTION: Be careful not to let any foreign
substance go into the filler opening when
refilling the oil.
