• Always stay away from the reach zone, in which the power
tool moves during recoil. As a result of recoil, the power tool
moves in the opposite direction to the movement of the grinding
wheel, where it locks.
• Corners, sharp edges, etc. should be worked with special
attention. Recoil or locking of the working tools should be
prevented. A rotating working tool is more prone to seizure,
when working angles, corners, sharp edges or when it is rebound.
This may result in loss of control or recoil.
• Do not use discs for wood or toothed discs. Working tools of
this type often cause recoil or loss of control over the working
tool.
Special safety guidelines for grinding and cutting with the
grinding wheel.
• Always use the grinding wheel intended for a given power
tool and guard intended for a given grinding wheel. Grinding
wheel that are not part of equipment of a given power tool may
be insufficiently covered or safe.
• Offset grinding wheels should be fastened so that their
grinding surface does not protrude beyond the protective
guard. Incorrectly seated grinding wheel and protruding beyond
the edge of the protective guard may not be sufficiently covered.
• The guard must be secured to the power tool to ensure the
highest possible safety level and positioned so that the
uncovered part of the grinding wheel facing the operator is
as small as possible. The guard protects the operator against
chips, accidental contact with the grinding wheel and sparks,
which may set clothing on fire.
• Grinding wheels can only be used according to its purpose.
• The side surface of the grinding wheel should not be used
for cutting. Cut-off grinding wheels are designed for removal of
material with the disc edge. The influence of lateral forces on the
grinding wheels may break them.
• Undamaged fastening flanges of a correct size and shape
should always be used for a selected grinding wheel. Proper
flanges support the grinding wheel and reduce the risk of its
breaking. Flanges for cut-off wheels may differ from flanges
designed for other grinding wheels.
• Do not use worn grinding wheels from larger power tools.
Grinding wheels for larger power tools are not designed for
higher rotational speed, which is specific to smaller power tools.
Thus, such grinding wheels may break.
Additional specific safety guidelines for cutting with a cut-off
wheel
• Always prevent a cut-off wheel from seizure and avoid
excessive pressure. Do not make too deep cuts. The overload
of a cut-off wheel increases its load and tendency for seizure or
locking, and thus may result in recoil or breaking of a cut-off
wheel.
• Avoid areas in front of and behind a rotating cut-off wheel.
When a cut-off wheel is moved onto a workpiece away from the
operator, it may cause the power tool to kick back as a result of
recoil, with a rotating cut-off wheel pointing directly towards the
operator.
• When a cut-off wheel seizes or you take a break from
work, switch off the power tool and wait until it comes to a
complete stop. Do not attempt to remove a rotating cut-off
wheel from a cutting place, since it may cause recoil. Find
and eliminate a cause of seizure.
• Do not switch the power tool back on, if it is still sunk in a
workpiece. Before you continue to cut, a cut-off wheel must
reach its full rotational speed. Otherwise, a cut-off wheel may
catch, spring back from a workpiece and cause recoil.
• Boards and large objects should be supported to reduce
the risk of recoil caused by a seized cut-off wheel. Large
objects may bend under their own weight. A workpiece should be
supported from both sides, both near the cut line and its edge.
• Special caution should be exercised, when holes are cut
in a wall or in confined spaces. As a cut-off wheel sinks into
a workpiece, it may cause the power tool to recoil, when it
encounters a gas or water supply line, power conductors or other
objects.
Specific safety guidelines for sanding with sandpaper
• Do not use too large sheets of sandpaper. Always follow
guidelines of a manufacturer, when the size of a sandpaper
is selected. Sandpaper protruding beyond a grinding disc may
cause injuries and result in locking and tearing of sandpaper, or
recoil.
Specific safety guidelines for working with wire brushes
• It should always be remembered that pieces of wire are lost
even during normal use. Do not overload wires by putting
excessive pressure. Airborne pieces of wire may easily puncture
thin clothing and/or skin.
• If a guard is recommended to be used, prevent a brush from
touching the guard. A brush diameter for plates and pots may
increase due to the pressure and centrifugal forces.
Additional safety guidelines
• Before connecting to the power source, always make sure
the supply voltage is compatible with the value specified on
the nameplate of the tool.
• Before the grinder is connected, always check the power
cord. In case of damage, have it repaired in an authorised
workshop.
• Before all installation works, the plug should be taken out
of the receptacle.
• Grinding tools should be checked before each use. A
grinding tool must be correctly fastened and should rotate
freely. As part of the test, the tool should be switched on
with no load for at least one minute in a safe position. Do
not use damaged or vibrating grinding tools. Grinding tools
should be round. Damaged grinding tools may break and
cause injuries.
• Once a grinding tool is installed and before the grinder is
switched on, check the grinding tool for correct installation
and free rotations, and whether it does not catch the guard.
• The spindle lock button can be activated, only when the
grinder spindle does not move.
• In case of tools adapted for fastening of grinding wheels
with a threaded opening, make sure the grinding wheel
thread length is suitable for the spindle thread length.
• Always secure the workpiece. It is always preferable to
secure the workpiece in a vice or other fastening tool than
holding it in your hand.
• If own weight of the workpiece does not guarantee a stable
position, it should be fastened.
• Do not touch cut-off and grinding wheels, before they cool
down.
