Sealey Air Impact Wrench - 3/8"" Square Drive

The working torque is 105 lb.ft (143 Nm).

It requires an operating pressure of 90 psi and an air consumption of 4.5 cfm.

While it has a maximum torque of 135 lb.ft, it is primarily designed for lighter to medium-duty tasks and engine bay work. For heavy-duty lug nuts, a higher torque impact wrench may be more suitable.

The tool features fingertip forward/reverse throttle control. You can switch directions easily with a touch of your finger while operating the trigger.

It is recommended to lubricate the tool with air tool oil through the air inlet before each use or at least daily if used frequently.

Please refer to the Sealey warranty documentation for the specific warranty period applicable to this model. Typically, Sealey offers a manufacturer's warranty on their tools.

Yes, as long as your compressor can consistently supply 90 psi and at least 4.5 cfm. Smaller compressors might struggle to maintain optimal performance.

Check air pressure is set to 90psi. Ensure the air compressor is providing adequate cfm (4.5cfm minimum). Lubricate the tool with air tool oil. Check the air hose for kinks or restrictions. Ensure the correct socket size is used and is fully seated on the fastener.

Ensure the tool is properly lubricated. Check for any obstructions in the air inlet or hammer mechanism. Verify the direction control is fully set to forward or reverse. If the issue persists, the internal hammer mechanism may require professional servicing.

Inspect all connections, particularly the air inlet fitting and any housing seams, for cracks or loose connections. Tighten fittings if necessary. If the leak is from the housing itself, the tool may need professional repair.

This is often due to insufficient air supply (low pressure or cfm) or lack of lubrication. Re-check compressor output and ensure regular oiling of the tool. Ensure the air hose is of adequate diameter and length to prevent pressure drop.
