Troubleshooting

The wrench will not advance.

1. The couplings are not fully connected or defective.

1. Tighten or replace the couplings.

2. The wrench piston seals or swivel manifold seals are defective.

2. Replace the seals.

3. The pump solenoid is defective.

3. Replace the pump solenoid. Refer to the product instructions for the pump.

The wrench will not retract.

1. See above.

1. See above.

2. Drive pin failure.

2. Replace the drive pin.

3. Pawl spring failure.

3. Replace the pawl springs.

4. Ratchet or drive pawl failure.

4. Replace the damaged components.

The wrench will not advance but gauge shows pressure.

1. The couplings are not fully connected or defective.

1. Tighten or replace the couplings.

2. The pump solenoid is defective.

2. Replace the pump solenoid. Refer to the product instructions for the pump.

The wrench operates in reverse (screw-to connect couplings only).

1. The couplings are reversed on either the wrench, the pump, or the hose.

1. Correct the orientation of the couplings. Refer to the section Connecting the System - Screw-to-Connect Coupling.

2. An even number of hoses are being used in the system, reversing the direction of the oil flow.

2. Change the number of hoses in the system to an odd number to correct the direction of the oil flow.

Wrench pressure will not build.

1. The wrench piston seals or swivel manifold seals are defective.

1. Replace the seals.

2. The pump pressure regulator valve is defective.

2. Replace the regulator valve. Refer to the product instructions for the pump.

3. The pump voltage is too low because of using extension cables.

3. Use a shorter extension cable or increased wire section. Refer to the product instructions for the pump.

4. The pump air pressure or air flow is too low.

4. Refer to the product instructions for the pump for requirements.

5. There is a restriction in the Filter Regulator Lubricator (FRL) because of excessive moisture or dirt in the air supply.

5. Repair or replace the FRL. Refer to the product instructions for the pump.

6. The pump's oil level is low or the filter is blocked.

6. Fill the oil tank or clean the filter. Refer to the product instructions for the pump.

Wrench operation is slow.

1. The couplings are not fully connected or defective.

1. Tighten or replace the couplings.

2. There is a restriction in the hydraulic or pneumatic (air pump) hose.

2. Replace the hose.

3. The pump's voltage, air pressure, or air flow is too low.

3. Refer to the product instructions for the pump for requirements.

4. There is a restriction in the Filter Regulator Lubricator (FRL) because of excessive moisture or dirt in the air supply.

4. Repair or replace the FRL. Refer to the product instructions for the pump.

5. The pump's oil level is low or the filter is blocked.

5. Fill the oil tank or clean the filter. Refer to the product instructions for the pump.

6. There is an internal leakage in the wrench or the co-axial coupling.

6. Replace the seals.

7. There is an internal leakage in the pump.

7. Refer to the product instructions for the pump for troubleshooting.

The ratchet is not taking successive strokes.

1. The ratchet, drive pawl, or drive pawl springs are damaged.

1. Replace the damaged components.

2. Drive pin spring failure.

2. Replace the spring.

3. Drive pin failure.

3. Replace the drive pin.

The ratchet jumps during advance stroke.

1. The ratchet, drive pawl, or drive pawl springs are damaged.

1. Replace the damaged components.

No reading on the pressure gauge but the wrench is operating.

1. The pressure gauge is defective.

1. Replace the pressure gauge.

Difficult to connect the hose to the wrench or pump.

1. Pressure retained in the hose.

2. The coupling is damaged.

1. Vent pressure in the hose.

2. Replace the coupling.

Oil is leaking from shroud.

1. The rod seal is damaged.

2. The internal piston seal is damaged.

1. Replace the rod seal.

2. Replace the piston seals.

The swivel or coaxial coupling is hot.

1. The seals are worn or damaged.

1. Replace the seals.

The coupling leaks oil after disconnection.

1. Sticking coupling, possible contamination.

1. Reconnect and disconnect. Clean the couplings and look for debris.

2. The coupling is damaged.

2. Replace the coupling.
