Blocking the cutting disc leads to jerking reac-
tion forces on the machine. In this case switch
off the machine immediately.
Pay attention to the dimensions of the grinding
disc. The mounting hole diameter must fit the
mounting flange 9 without play. Do not use re-
ducer pieces or adapters.
Never use cutting discs for rough grinding. Do
not exert any lateral pressure on the cutting
discs.
Observe the manufacturer's instructions for
mounting and using grinding tools.
Caution! The grinding tool runs on after the
machine is switched off.
Do not clamp the machine in a vice.
Never allow children to use the machine.
BTI is only able to ensure perfect operation of
the machine if the original accessories in-
tended for it are used.
Mounting the Protective
Devices
Before any work on the machine itself, pull
the mains plug.
For work with grinding or cutting discs, the
protection guard 6 must be mounted.
Protection Guard with Locking Screw
The coded projection 8 on the protection guard 6
ensures that only a guard that fits the machine
type can be mounted.
Loosen the clamping screw 7, if necessary.
Place the protection guard 6 with coded projec-
tion 8 into the coded groove on the spindle collar
of the machine head and rotate to the required
position (working position).
The closed side of the protection guard 6
must always point to the operator.
Tighten clamping screw 7.
Auxiliary Handle
For all work with the machine, the auxiliary
handle 4 must be mounted.
Screw the auxiliary handle 4 into the head of the
machine according to the working method.
Do not make any alterations to the aux-
iliary handle.
Do not continue to use an auxiliary handle if it is
damaged.

Hand Guard
For work with the rubber sanding pad 17 or with
the cup brush 20/disc brush/flap disc, mounting
the hand protector 15 (accessory) is recom-
mended. The hand protector 15 is fastened with
the auxiliary handle 4.
It is recommended to use the quick-clamping
nut 12. When using the clamping nut 11 in-
creased effort to loosen the clamping nut must be
taken into account.
Actuate the spindle lock button 2 only when
the grinder spindle is at a standstill!
Quick Clamping Nut
When using the quick-clamping nut 12, grinding
tools can be mounted without additional tools.
Use only a flawless, undamaged quick-clamp-
ing nut 12.
When screwing on, take care that the side with
printing does not point to the grinding disc. The
arrow must point to the index mark 25.

Mounting the Grinding Tools
Before any work on the machine itself, pull
the mains plug.
Use only grinding tools with a permissi-
ble speed at least as high as the no-load
speed of the machine.
Grinding and cutting discs become very
hot while working; do not touch until
they have cooled.
Clean the grinder spindle and all parts to be
mounted. For clamping and loosening the
grinding tools, lock the grinder spindle 5 with
the spindle lock button 2.
