4.3 Periodic Inspection Items

4.3.1 Inspection on Initial 50 Hrs. of
Operation (or after 1 Month)
(1) Replacing the Engine Lube Oil and
Lube 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
lube oil filter at the same time.
It is easiest and most effective to drain the
engine lube oil after operation while the
engine is still warm.
1. Remove the lube oil dipstick. Attach the
oil drain pump and drain off oil.
2. Remove the lube oil filter with the filter
detach/attach tool. (Turn to the left.)
3. Clean the filter installation face and
attach the new filter, tightening by hand.
4. Turn an additional
attachment tool. (Turn to the right.
Tightening torque: 20 ~ 24 Nm)
5. Fill with new lube oil. (See 3.2.3)
6. Perform a trial run and check for oil
leakage.
7. Approximately 10 minutes after stopping
the engine, remove the oil dipstick and
check the oil level. Add oil if the level is
too low.

(3) Draining the (optional) Fuel Tank
Open the drain cock and drain off any
water or dirt collected on the bottom.
Put a pan under the drain to catch the fuel.
Once the water and dirt has been drained
off and the fuel coming out is clear, close
the drain cock.
(4) Inspection and Adjustment of
Intake/ Exhaust Valve Head
Clearance (1st time)
Settling of a new engine and individual
engine use will cause changes in the
intake/exhaust valve and rocker arm clear-
ance, and adjustment is necessary. This
adjustment requires specialized knowledge
and techniques. Consult your Yanmar
dealer or distributor.
