Instructions for checking the oil level and purging the air in the jack puck press

Filling Oil in Jack Pucks:

Adding Hydraulic Fluid:

1. Turn Release Valve counterclockwise to allow ram to fully retract. It may be necessary to apply force to the saddle for lowering.

2. Stand jack in vertical position with saddle at the top.

3. With the jack in the vertical position, remove the oil fill plug. Oil should be level with the bottom of fill hole. If not, top off. Do not overfill. Always fill with new, clean hydraulic jack oil.

4. Replace fill plug.

5. Check jack operation.

It may be necessary to purge air from the hydraulic system

Before following next steps, make sure release valve is closed.

To Purge Air:

1. Turn release valve counterclockwise one full turn to open.

2. Pump handle rapidly for eight full strokes.

3. Turn release valve clockwise to close valve.

4. Pump handle until the saddle reaches maximum height to remove trapped air in the arm.

5. Turn release valve counterclockwise one full turn and lower saddle to the lowest position. Use force if necessary.

6. Turn release valve clockwise to closed position and check for proper pump action. It may be necessary to perform the above more than once to assure air is evacuated totally.
