B. ENGINE
Check engine oil level --- every 10 hours (before
1
starting the engine)
Check the oil level before starting the engine. Remove dipstick
(1). Check for mixing of foreign matter or contamination in the
oil. Wipe oil off the dipstick with a clean cloth. Reinsert dipstick
(1) and remove it again. Read level. Oil level must be within the
specified range on dipstick (1). If necessary, add the recom-
mended engine oil via oil filler (2). Recheck oil level after add-
ing the oil.
NOTE: Level the engine when adding oil or inspecting oil level.
When required to check oil level after operating the
machine, first stop the engine. Wait for more than 15
minutes. Then check oil level. (This means that the oil
level will become stabilized after all oil delivered to re-
spective lubrication area returns to the oil pan.) In case
the oil color change, severe contamination, and/or
mixing of foreign matter is found, change the oil.

WARNING: Immediately after the machine was oper-
ated, all engine parts are hot. Wait for the engine to
cool before starting any maintenance work. Failure to
do so may cause severe burns.
NOTE: Improper disposition of waste oil can threaten the
earth's environment and ecology. Dispose the waste oil
in accordance with the local regulation and/or law. Be
sure to replace the engine oil filter when changing the
