2
.
7.1.2 Turn the air drain bolt anti-clockwise around 1/4 ~ 1/2 circle, then pump starts
working.
7.1.3 Wait for around 20 seconds in order to exhaust air completely.
7.1.4 Turn the air drain bolt clockwise to fasten it, and then pump stops working
(hydraulic pressure is raising).
7.1.5 If the pump still working. It means the air didn
’
t exhaust completely, please
repeat step 7.1.2 ~ 7.1.4. till air is exhausted completely.
7.1.6 Adjust air regulator to required pressure.
7.2 At connector between high-pressure hose and cylinder of the slide：
7.2.1 Adjust air regulator to 2 ~ 3 kgf/cm
2
.
7.2.2 Loosen the connector of high-pressure hose from slide, then pump starts working.
7.2.3 Check the oil is which flowed out of high-pressure hose, till the oil didn
