Grinder Stand
With the grinder stand 26 (accessory), work-
pieces can be cut at angles of 0 to 45° at the
same lengths.
The safety notes and operating instructions in the
respective operating instructions manual of the
angle grinder are to be strictly observed. Use only
original BTI 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 22 with the special dust extraction protec-
tion 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).
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.

The vacuum cleaner
must be approved for
the extraction of ma-
sonry dust.
BTI provides suitable
vacuum cleaners.
Switch on the ma-
chine and place the
front part of the cut-
ting guide on the
workpiece.

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 24 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
guide/grinder stand (accessories) and for left-
handers.
Pull the handle unlocking button 23 firmly in the
direction of the arrow ( ), turning the handle 24
at the same time to the desired position ( ) until
it engages. The figure shows the handle 24
turned by 90°.
The handle unlocking button 23 and the
On/Off switch 3 have a safety interlock.
The machine cannot be switched on if the han-
dle 24 is not engaged in one of the three pos-
sible positions.
The handle 24 cannot be unlocked if the
On/Off switch 3 is locked.
