Warnings related to the work with the wire brush
Be careful, as wire fragments are also ejected from the brush during normal operation. Do not overload the wires by
applying too much pressure to the brush. The wires can easily pierce thin clothing or skin.
If the use of guards is recommended during the work with the wire brush, prevent any contact of the brush with the
guard. The wire brush can increase its diameter under load and centrifugal force.
Safety warnings related to polishing
Do not allow any loose part of the polishing disc or fastening cord to rotate freely. Loose and rotating cords can entangle
in the fi ngers or be caught in the workpiece.
EQUIPMENT INSTALLATION
Installation of the abrasive disc guard
To do this, place the disc guard on the cylindrical part of the body around the spindle and use a screw or clamp to fi x the guard
so that it is attached straight, fi rmly and securely. Place the abrasive disc guard so that the covered part of the disc is as far away
from the hand of the grinder as possible. Never operate the grinder without the disc guard installed correctly!
The grinder is supplied with a guard to ensure proper protection only when sanding with abrasive discs and discs using sandpaper
and some wire brushes. The disc must not protrude beyond the side edge of the guard when mounted on the spindle. If any other
type of authorised work is carried out, contact the manufacturer for a guard intended for this type of work.
When using a Type A guard (for cutting) for grinding with a lateral surface, the guard may interfere with the workpiece causing
poor control of the tool. When a Type B guard (for grinding) is used for cutting with a grinding wheel, the risk of exposure to sparks
and particles increases, as well as to parts of the wheel in the event of a breakage. When using a Type A (for cutting), Type B (for
grinding) or Type C (combined) guard for cutting or grinding of concrete or stone with side surface, the risk of exposure to dust and
loss of control due to kickback towards the operator increases. When using a Type A (for cutting), Type B (for grinding) or Type C
(combined) guard with a disc wire brush of a thickness that will cause the brush to protrude beyond the guard fl ange, it may cause
the wires to catch the guard, which will cause the wires to break.
Installing the additional handle
Install the handle by screwing it securely to the tool head.
HANDLING OF THE GRINDING DISCS
CAUTION! Install the abrasive discs when the supply voltage is disconnected. Remove the battery from the tool socket!
Positioning of the fi xing fl anges
Note that the discs at the place of fi xing to the spindle may be of di ff erent thickness.
Depending on the thin abrasive discs used (thickness up to 3.2 mm) or thick ones (thickness over 3.2 mm), the location of the
fi xing fl anges (III) is di ff erent. The maximum thickness of the abrasive disc that can be attached to the grinder is 6 mm.
Grinding wheel assembly
Disconnect the supply voltage from the tool. Remove the battery from the tool socket!
During installation, make sure that the edges A (IV) at the bottom of the spindle tip and the fi xing fl anges overlap thoroughly.
Place the upper fi xing fl ange on the spindle.
Place the abrasive disc on the spindle and the upper fi xing fl ange
Screw the lower fi xing fl ange on the spindle.
Press the spindle lock and tighten the lower fastening fl ange with a wrench and then release the pressure on the lock button.
Install the battery, turn the grinder on and observe its operation without any load for about 1 minute.
Remove the battery and check the disc for proper installation.
Removing the abrasive discs
Turn o ff the grinder and remove the battery from the tool socket.
Press the spindle lock and unscrew the lower fi xing fl ange with the fi xing wrench and then remove the abrasive disc from the
spindle. Clean the spindle and the fi xing fl anges of dust and other contaminants generated during operation.
Types of grinding wheels
Any grinding wheel reinforced with a plait intended for use with angle grinders with a permissible circumferential speed of at least
80 m/s and fi xing and external diameters speci fi ed in the technical data table may be used with the grinder.
If the grinding wheel is provided with a non-threaded hole for its assembly, use the fi xing fl anges.
It is also possible to assemble wheels with an external diameter speci fi ed in the technical data table, equipped with a M14
threaded hole. In this case, do not use fi xing fl anges and screw the wheel directly to the spindle, locking it with a button, and
tightening the wheel fi rmly and securely using a fl at wrench (not included with the grinder).
