edge of the protection. In case of any other permitted task, contact the manufacturer in order to purchase a guard for such kind
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.
Installation of the additional handle
If required install the handle screwing it securely to the head of the tool.
USING ABRASIVE DISKS
ATTENTION! Installation of the abrasive disks must be realised with the power supply o ff . Remove the plug of the cord of the
grinder from the socket
Installation of abrasive disks
Disconnect the tool. Remove the plug from the socket!
During installation make sure the edges A (IV) at the bottom spindle mandrel and the fi xing disks align precisely.
Place the upper fi xing disk on the spindle.
Place the abrasive disk on the spindle and the installed fi xing disk.
Screw the lower fi xing disk onto the spindle.
Press the spindle blockade and tighten the lower fastening disk with a spanner and release the blockade.
Insert the plug of the power supply cord of the tool into the socket, turn the grinder on and observe its operation without any load
for approximately one minute.
Remove the plug from the socket and make sure the disk is installed securely.
Position of the fi xing disks
Please note that the discs may have di ff erent thickness in the area in which they are installed on the spindle.
Depending on the abrasive disks used - thin ones whose thickness does not exceed 3.2 mm or thick ones whose thickness ex-
ceeds 3.2 mm) the position of the fi xing disk di ff ers (III). Do not use the discs thicker than 6 mm.
Removal of the abrasive disks
Turn the grinder o ff and remove the plug of the electric cord of the grinder from the mains socket.
Press the spindle blockade and unscrew the lower fi xing disk using a spanner, and remove the abrasive disk from the spindle.
Clean the spindle and the fi xing discs removing dust and other contamination generated during work.
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 thread-
ed 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).
In the case of wheels enabling the installation of the sandpaper disc with Velcro, only sandpaper discs with the diameter speci fi ed
in the technical data table should be used. The disc should be placed concentrically on the wheel. The edge of the disc must not
project beyond the edge of the wheel.
It is also possible to use diamond grinding wheels with the dimensions speci fi ed in the technical data table intended for dry cutting
and grinding. Perform the assembly in the same manner as in the case of grinding wheels. When using diamond segmented discs,
the gap between the segments must not exceed 10 mm, measured at the perimeter of the disc, and the segments must have a
negative angle of attack.
It is recommended to use grinding wheels made of materials intended for machining a given type of metal. Refer to the documen-
tation provided with the grinding wheel.
Grinding wheels intended for machining stone or diamond grinding wheels for dry working can be used for the machining of
ceramic materials.
It is recommended to use wire brushes and sandpaper discs to remove old paint coats from metal parts.
It is forbidden to modify the fi xing hole, spindle or use reduction rings to adjust the diameter of the fi xing hole to the spindle diame-
ter. It is forbidden to use grinding wheels with a fi xing hole diameter other than speci fi ed in the technical data table. It is forbidden
to use grinding wheels with a cutting chain or cutting discs because they increase the risk of tool kickback towards the operator.
