Product Information

Full details

The Laser Tools 7681 Mini Air Impact Wrench is designed for professional mechanics and automotive enthusiasts who frequently work in cramped engine bays or tight automotive spaces. By combining a 949Nm torque output with a lightweight, compact frame, it allows for high-power fastener removal without the fatigue associated with bulkier tools; however, users should note that the high torque output requires a consistent, high-pressure air supply to operate at peak performance.

FAQs

What is the drive size of this tool?

The Laser Tools 7681 features a standard 1/2" square drive.

Does it come with grease?

Yes, it includes a 20g tube of Molybdenum Disulphide grease.

What is the recommended operating pressure?

The tool is designed to operate optimally at 90 PSI.

Can this be used with standard hand-tool sockets?

Troubleshooting

Wrench lacks power

Check your air compressor pressure settings (should be 90 PSI) and ensure your air hose is not restricted or too thin.

Air leaking from the handle

Check the air inlet connection and ensure the thread seal tape is applied correctly; inspect the housing for any debris in the O-rings.

Tool running sluggishly

Inject Molybdenum Disulphide grease into the grease port and check the air inlet filter for clogs.
