CAUTION
Risk of injury! Grinding makes the workpiece hot.
▶ Do not attempt to touch the workpiece immediately after grinding and always wear suitable protective
gloves to prevent burns. Keep everyone clear of your work zone.
Before grinding, always check that the abrasive belt is centered on and in full contact with the rollers.
Never force the abrasive belt at an angle to the direction of travel.
1. Lift the pipe belt grinder clear of the work surface.
2. Switch the tool on. → page 7
➥ The power tool then runs in sustained operating mode.
3. Set the belt speed. → page 7
4. Bring the pipe belt grinder with the abrasive belt into contact with the workpiece. Grinding takes place
between rollers A and B.
5. The arc of contact and the rate of abrasion can be influenced by varying the contact pressure.
➥ The smaller the pipe diameter, the larger the possible arc of contact.
