30 TESTING AND ADJUSTING
Method of checking oil level and operation
1.
Start the engine, retract the arm cylinder and bucket cylin-
der fully, lower the work equipment to the ground, and stop
the engine.
2.
Check the oil level by sight gauge (6) at the rear of the hy-
draulic tank.
When the oil level is between the lines "H" and "L", it is
correct.
When the oil level is below line "L", it is insufficient. Add
more oil.
