Initial Operation
Observe correct mains voltage: The voltage of
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.
Switching on: On/Off switch 7 to position I.
Switching off: On/Off switch 7 to position O.
Test run: Before using for the first time,
run machine for at least 5 min-
utes without load.
Dress a new grinding wheel with
a dressing stone.
Grinding Wheel Replacement
Pull the plug from the socket.
Loosen the 3 screws of the protective cover 1
and remove the protective cover. Unscrew the
clamping nut 2 while holding the grinder spindle 5
with an open ended spanner on the spanner sur-
faces of the respective side.
Caution: Grinder spindle 5 has left-handed
threads on the left side!
Remove clamping flange 3 and grinding wheel.
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.
The maximum allowable RPM of the grinding
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
(accessory).
Dress used, out of round grinding wheels
with the dressing stone (accessory) before
continuing to use.
Operating Instructions
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.
