First, perform an operation check by repeating "C direction rotation and stopping and A direction rotation and stopping" a number of times at low-speed rotation. At this time, remaining air inside the circuit may cause abnormal noises from the valves, etc. The abnormal noises will stop as air is bled out while operation is done repeatedly at low speed. If abnormal noises go away through repeated operation over a while, there is no problem with the motor and it can be used as is. If operation is done repeatedly and abnormal noises do not stop, there is an abnormality within the motor and it should be replaced. Check for the presence of oil leaking from the motor, line port sections, each line and each piece of equipment. When oil leaking has been confirmed, retighten the bolts and line joints at the location where the leak is occurring to the specified torque. After checking is completed, raise the pressure and perform load operation, and check that no abnormal noises or vibrations, etc. are occurring in the motor. NOTICE: • When tightening lines, etc. after confirming oil leaking, make sure to have operation of hydraulic devices stopped. • Make sure that the operating pressure on the motor is low when checking for oil leaking. If the operating pressure is high and there is oil leaking, there is the danger of oil spraying out.
