Trying out after fitting a new diamond cup wheel

CAUTION
Risk of injury. Damaged diamond cup wheels can come loose.
▶ Do not use a diamond cup wheel if it vibrates; protect the cup wheel against impact, shock loading and
grease.
▶ Allow the power tool to run for at least 1 minute without load.
6.3 Grinding
1. Connect the grinder to an industrial vacuum cleaner.
2. Lift the power tool clear of the work surface.
3. Switch the tool on. → page 19
➥ The device is now in continuous operation mode.
4. Set the desired speed.
➥ Use stages 3 to 6 for grinding with a diamond cup wheel. You get the highest rate of abrasive removal
with stage 6.
➥ Use stages 1 to 2 for fine-grinding. With stage 1 you have better control over the device and the
finished result is finer.
5. Bring the device with the accessory tool into full contact with the work surface and keep the tool moving
with a steady back-and-forth action.
6. Apply moderate pressure and do not dig the tool into the material.
