To make sure your clamp works efficiently, it is important to keep all the parts clean. Any dirt may damage the ability of the tool and stain the surface of your workpiece during clamping.
After every use wipe the clamp with a dry cloth to clear any dust or debris that may have built up.
Regularly oil all the moving parts to keep them in tip-top condition and prevent rust from developing.
Storage
Store your clamp in a safe and dry place, such as on a shelf in a garage or work shed.
