1 Prepare for safe work
Unplug your tool from the outlet or remove the battery. Clear your work area, secure the object, and put on eye, ear, and breathing protection depending on the job type.
⚠ Warning: Don’t bypass safety shields, switches, or grounding. Leave electrical faults and damaged housings to professional service.
2 Identify the exact symptom
Clean the jaws and the guide, then close the clamp without an object and check whether the gap is even across the full width.
3 Check the most common cause
Check whether the replaceable jaws are seated properly and whether the screws are tightened evenly. Replace a damaged jaw in pairs.
4 Fix the cause without improvising
Lubricate the screw and sliding surfaces according to the instructions. Don’t try to force a bent body or a loose nut, as it may break.
? Tip: Take a photo of the initial state and change only one thing at a time. That way you’ll more easily recognize what actually fixed the problem.
5 Reassemble and test safely
Put all shields back in place and do a quick test without load, then try it on scrap material. Stop if the tool vibrates, sparks, overheats, or makes an unusual noise.
