Checking the Lube Oil and Cooling Water

When lube oil, gear oil, and cooling water are put in for the first time, or after they have been replaced,

their levels should be checked after a trial operation. Oil and water will be distributed to the various parts

during the operation, lowering the levels of oil and water. Replenish to the proper amounts.
