# Troubleshooting the Tool

Problem | Possible Reason | Action
--- | --- | ---
The wedge is advancing but does not reach full pressure | Air could be present in the hydraulic system | Use the airlock removal procedure

Airlock Removal Procedure

1. Connect the hand pump to the tool with the hydraulic hose.

2. Close the release valve on the pump, and prime the pump until the hydraulic cylinder is fully extended and a small pressure is achieved.

3. With the hand pump held above the tool and the tool in an upright position, open the release valve causing any air that is within the system to be forced up through the pump and vented into the oil reservoir.

4. Repeat steps 1–3 three or four times to ensure that all air is removed from the system and the tool will reach full working pressure.

5. Disconnect the hand pump from the hydraulic hose, grip the baseplate of the hand pump body in a vice with the pump body vertical and the main handle at the top.

6. Remove the four nuts holding the main handle and lift off.

7. Grip the refilling plug with pliers and extract it by pulling and twisting simultaneously. Ensure the reservoir body is held down when removing the refilling plug as pulling up on the reservoir body will release the bladder within, and oil will spill out.

8. Fill the reservoir to the top with a good quality hydraulic oil of the grade 15 cSt.

9. Reinsert the refilling plug, wipe away any oil, and reassemble by reversing the disassembly process.
