Troubleshooting

Free speed is too slow, pressure never reaches the target.

Too low air flow in the pressurized air system.

Shorter hose to the FRL unit and larger diameter are needed. Check air flow for free speed in the specifications for the directions of required air flow at free speed.

The tool cannot loosen a nut.

Corrosion and worn-out bolt and nut have affected the joint-loosening torque.

Apply a higher torque, within the torque chart spec. If it does not help, use a larger tool, if available, to remove the nut. Do not apply a higher pressure than specified, as it will shorten the service life of the tool.

The tool has been flushed with a large amount of water.

The pressurized air system is affected by a large amount of condensed water.

See service recommendation for specific environments.
