Check the oil pump of the intake system and turn on the oil provided by the automatic rotary punch oil pump to each wetting point

Check whether the oil level in each oil gauge is achieved in the middle secant position;

Check whether the bottom mark value of each working pressure is within the given scope;

Check overpressure protection equipment, after ventilation, automatic small punch pneumatic pump should start working, to achieve rated working pressure within five minutes, pneumatic pump stop working;

Check indicator light;

Check the emergency stop button: press the button can be locked, along the arrow symbol orientation of 90° to calibrate;
