Filling oil and inspection
NOTE!
Do not overfill the oil pan with engine oil. Be sure to keep the specified level between upper and lower
limit on the dipstick.

Warm up the engine by running for 5 minutes while checking any oil leakage.
Stop the engine after warming up and leave it stopped for about 10 minutes then recheck the engine oil
level with dipstick and replenish the engine oil. If any oil is spilled, wipe it away with a clean cloth.

Checking and adjusting radiator fan V-belt

When there is not enough tension in the V-belt, the V-belt will slip making it impossible for the alternator to generate power
and water pump and cooling fan will not work causing the engine to overheat. Check and adjust the V-belt tension
(deflection) in the following manner.



Press the V-belt with your thumb [approx. 98N (10kgf)] at the middle of the V-belt span to check the tension
(deflection).
Available positions to check and adjust the V-belt tension (deflection) are at the A, B or C direction as shown in the
illustration right.
You may choose a position whichever you can easily carry out the check and adjustment on the machine unit.

"New V-belt" refers to a V-belt which has been used less than 5 minutes on a running engine.
"Used V-belt" refers to a V-belt which has been used on a running engine for 5 minutes or more.
The specified deflection to be measured at each position should be as follows.
