the power source must agree with the voltage
specified on the nameplate of the machine.
Equipment marked with 230 V can also be con-
nected to 220 V.

The mounting of the new grinding wheel is per-
formed in the reverse order. Press the protective
cover 1 on firmly and tighten the screws.
Testing new grinding wheels
Use only original Bosch grinding wheels!
Damage to the original packaging could indicate
defects. Check before mounting that the grinding
wheel is free of damage.

wheels used must at least correspond to the
maximum no-load RPM of the machine.
Test run new grinding wheels at least 5 min-
utes and then dress with the dressing stone
Dress used, out of round grinding wheels
with the dressing stone (accessory) before

Lay the workpiece to be ground on the tool
rest 11 and press lightly against the grinding
wheel. To achieve optimal grinding results, move
the workpiece lightly back and forth. This also
contributes to uniform wear of the grinding wheel.
