Cut Off Grinder Stand
With the cut off grinder stand 27 (accessory),
workpieces can be cut at angles of 0 to 45° at the
same lengths.
The safety notes and operating instructions in the
respective instruction manual of the cut off
grinder stand are to be strictly observed. Use only
original Bosch cut off grinder stands.
Cutting Stone
The machine must be used only for dry cutting/
grinding. It is best to use a diamond cutting disc.
As a safety measure against jamming, use the
cutting guide 24 with the special dust extrac-
tion protection guard.
Operate the machine with dust extraction only. In
addition, wear a dust mask.
Slide the machine with moderate feed, adapted
to the material to be worked (Figure).

The vacuum cleaner

the extraction of ma-
sonry dust.
Bosch provides suit-
able vacuum clean-
ers.
Switch on the ma-
chine and place the
front part of the cut-
ting guide on the
workpiece.

For cutting especially hard material, e. g., con-
crete with high pebble content, the diamond cut-
ting disc can overheat and become damaged as
a result. This is clearly indicated by circular
sparking, rotating with the diamond cutting disc.
In this case, interrupt the cutting process and al-
low the diamond cutting disc to cool by running
freely at no-load speed for a short time.
Noticeable decreasing work progress and circu-
lar sparking are indications of a diamond cutting
disc that has become dull. Briefly cutting into
abrasive material (e. g., lime-sand brick) can re-
sharpen the disc.
Turning the Machine Handle
The handle 26 can be turned with respect to the
motor housing by 90° either to the left or right.
This allows for the On/Off switch to be positioned
more conveniently for certain working situations,
e. g., for cutting work with the cutting guide /
grinder stand (accessories) and for left-handers.
Pull the handle unlocking button 25 firmly in the
direction of the arrow ( ), turning the handle 26
at the same time to the desired position ( ) until
it engages. The figure shows the handle 26
turned by 90°.
The handle unlocking button 25 and the
On/Off switch 3 have a safety interlock.
The machine cannot be switched on if the
handle 26 is not engaged in one of the
three possible positions.
The handle 26 cannot be unlocked if the
On/Off switch 3 is locked.
