Starting confirmation
Changing oil
Removing air
Flushing operation
・
After confirmation of the start, perform flushing operation under the circuit
pressure at low pressure. As flushing operation, connect all piping with
loop style except the actuator, and operate through 10
μ
m filter by the oil
tank of the return piping.
・
After completing the flushing operation, remove hydraulic oil in the tank
completely out of drain plug. Then fill fixed amount of flesh hydraulic oil
to the oil inlet port with air breather.

①
abnormal operation of actuator, such as cylinder
②
abnormal noise in the pump or in the valve
may occur.
・
Turn the switch of machine controller “ON”.
①
Before power on, confirm wiring of earth properly.
②
