Tips

Use a high-quality air line with the recommended 10 mm diameter to ensure consistent torque and speed. Regularly lubricate the air motor with a few drops of pneumatic tool oil before each use to extend service life. When working in tight spaces, the rear exhaust keeps air away from your face and the work surface.
