• Small workpieces should be fastened in a vice or using
clamps, for example. The workpiece should be fastened so
that it is cut near the fastening element. This will ensure
higher cutting precision.
• Do not allow the cut-off wheel to vibrate or jump, since this
will lower the quality of cutting and may cause the cut-off
wheel to break.
• Do not exert lateral pressure onto the cut-off wheel during
cutting.
• A proper cut-off wheel should be used depending on a
workpiece type.
• When a workpiece is cut, it is recommended that a cutting
direction is the same as rotation direction of the cut-off
wheel.
The cutting depth depends on a wheel diameter (fig. G).
• Only wheels with nominal diameters not larger than
recommended for a given grinder model should be used.
• Do not allow the fastening flanges to contact a workpiece in
case of deep cuts (e.g. sections, building blocks, bricks, etc.).
Cut-off wheels reach high temperatures during operation. It
cannot be touched with uncovered body parts, before they
cool down.
GRINDING
Grinding wheel, cup-type grinding wheels, flap wheels, wheels
with abrasive fibre, wire brushes and flexible discs, etc. should
be used for grinding. Each type of discs and workpiece requires
proper working method and personal protective equipment.
Cut-off wheels should not be used for grinding.
Grinding discs are intended for removal of material with an
edge of the disc.
• Do not use the lateral surface for grinding. The optimum
working angle for this disc type is 30° (fig. H).
• Works related to grinding can be performed only, when
proper grinding discs are used for a given workpiece.
When flap wheels, discs with abrasive fibre and flexible discs
for sandpaper are used, attention should be paid to the proper
tool angle (fig. I).
• Do not grind with the entire surface of a wheel.
• This disc type should be used for working flat surfaces.
Wire brushes are mainly used for cleaning sections and hard-
to-reach spaces. They can be used to remove rust, painting
coats, etc. from a workpiece surface (fig. K).
Only such working tools can be used, whose permissible
rotational speed is higher or equal to the maximum no load
speed of the grinder.
OPERATION AND MAINTENANCE
Before any operations related to installation, adjustment,
repairs or maintenance are commenced, the plug of the power
cord should be disconnected from the socket.
MAINTENANCE AND STORAGE
• It is recommended to clean the tool after each use.
• Do not use water or other fluids for cleaning.
• The tool should be cleaned with a dry piece of cloth or blown
with compressed air of low pressure.
• Do not use any cleaning agents or solvents, since they may
damage plastic parts.
• Venting slots in the motor housing should be cleaned on a
regular basis not to overload the tool.
• When the power cord is damaged, it should be replaced
with the power cord of the same parameters. It should be
performed by a qualified professional or the tool should be
delivered to an authorised service shop.
• When the commutator sparks excessively, have the condition
of motor carbon brushes checked by a qualified person.
• The tool should be always stored in a dry place and out of
reach of children.
REPLACING THE CARBON BRUSHES
Worn (shorter than 5 mm), burnt or cracked motor carbon
brushes should be immediately replaced. Both carbon brushes
should be always replaced at the same time.
Carbon brushes should be replaced by a qualified person
using original spare parts only.
All types of faults and defects should be eliminated by an
authorised service of the manufacturer.

NOISE AND VIBRATION DATA
Information regarding noise and vibration
The following levels of emitted noise, such as emitted acoustic
pressure Lp and acoustic power level Lw
A
uncertainty K have been given in the instruction manual as defined
in the EN 60745 standard.
The following vibration value (acceleration value) a
measurement uncertainty K have been determined as defined in
the EN 60745 standard.
The vibration level provided in this instruction manual have
been determined according to the measurement procedure
as defined in the EN 60745 standard and can be used for
comparison of power tools. This can be used for preliminary
assessment of exposure to vibrations.
