Air Purging Instructions

If the jack does not raise the load or raises very slowly after activating the pump pedal (R43) there may be air

trapped in the primary ram and/or pump core.

1. Loosen screw (R33.)

2. Press the release pedal (R40) when the 2 pistons (1st stage and 2nd stage) are in the lowest position.

3. Use a 3mm wrench to loosen the M6x8 bleed screw a half turn in the counterclockwise direction. Do not

remove screw.

4. Operate the pump pedal (R43) very slowly until hydraulic oil without bubbles is escaping from the hole of the

bleeder screw (usually 2 to 3 pumps are sufficient.)

5. Continue to hold pressure on the pump pedal (R43) and simultaneously tighten the bleed screw.

6. Release Pedal (R40) and operate Pedal (R42) to check condition. Repeat the above steps if condition has

not improved.

Please follow these instructions to eliminate air in the ram if the unit is not descending properly:

1. Loosen screw (R33.)

2. Operate Pump Pedal (R43) to extend rams to its highest position.

3. Use a 4mm wrench to loosen M8x10 bleed screw but do not remove.

4. Operate the Pump Pedal (R43) 2 or 3 times until there is hydraulic oil (without bubbles) escaping from the

hole of the bleed screw.

5. Continue to hold pressure on the pump while tightening bleed screw.

6. Press Release Pedal (R40) to retract the rams. Repeat above steps if condition persists.
