4.3 Periodic Inspection Items
4.3.1 Inspection after Initial 50 Hrs. Operation
（1）Replacing the Engine Lube Oil and Lube Oil Filter (1st time)
During initial operation of the engine, the oil is
quickly contaminated due to the initial wear of
internal parts. The lube oil must therefore be
replaced early.
Replace the Iube oil filter, too, at this time.
Engine lube oil is convenient to drain before the
engine has cooled down.
①Remove the lube oil dipstick and connect
the hose of the drain oil pump (optional part)
to the guide of the oil dipstick.
②Prepare a container to receive drain oil and
pump out oil using the drain oil pump.
③Remove the lube oil filter with the filter
wrench.
(Turn counterclockwise. )
④Clean the filter installation face.
⑤Screw the lube oil filter fully into the installa-
tion face by hand and further fasten the filter
by about 3/4 turns with the filter wrench.
(Turn clockwise.)
⑥Supply new lube oil to the specified level.
(See 3. 2. 2.)
Test operation the engine for 5 minutes.
Check that no oil leaks out during operation.
⑦Wait about 10 minutes after stopping the
engine. Check the oil level with the oil
dipstick and refill to the specified level.
