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.
• Do not exert lateral pressure on the grinding or cut-off wheel.
• Do not cut a workpiece of a thickness larger than the maximum cutting depth of the cut-off wheel.
• When quick release flange is used, make sure that inner flange seated on the spindle is equipped with
