If you release the air when the pump, cylinder and hose is connected, extend the cylinder piston fully,
then put the cylinder upside down, and operate the cylinder by pumping the oil. Air will be released to
the reservoir.

(B) Check if the oil volume is correct or not by retracting the cylinder piston completely and check if the
oil level can be seen from the port or not. If not, refill oil upto the upper line of the oil level gauge.

unusual vibration, or other unsusual conditions happen or not.
(D) Operate
air shut-off valve and
shut-off valve to operate cylinder, and to increase the pressure
of the cylinder, so as to check if unsual conditions happen or not.
