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 rubber O-ring and this ring
is not damaged. Also surfaces of the outer flange and the inner
flange must be clean.
• Use quick release flange only with cutting and grinding discs. Use
only flanges that are free from defects, that operate correctly.
• In case of temporary mains power failure or after disconnecting
plug from mains socket with the switch in ON position, unlock the
switch and set it to OFF position before starting the tool again.
NOTE: The tools is intended for indoor works.
Despite using the construction, which is safe by design itself,
protection means and additional safety features, there is always a
residual risk of injuries during operation.

DESIGN AND APPLICATION
The angle grinder is a hand-held power tool with the II class isolation.
The power tool is driven with a single-phase, commutator motor,
whose rotational speed is reduced by means of an intersecting axis
gear. The power tool can used both for grinding and cutting. This type
of power tools is widely used for removal of burrs from metal surfaces,
weld surface processing, cutting light-wall tubes and other small metal
objects etc. They are used in engineering industry, automotive and
chemical industry. With the use of proper tools, the angle grinder can
be used not only for cutting or grinding, but also for rust and paint coats
removal.
The areas of its application include repair and construction works, not
only related to metals. The angle grinder can also be used for cutting
and grinding of construction materials, such as brick, paving stones,
ceramic tiles, etc.
The power tool is designed for dry operation only and it must not
be used for polishing. The power tool should be used according to
its purpose.
Use inconsistent with its purpose
• Do not work materials that contain asbestos. Asbestos is carcinogenic.
• Do not work materials, whose dust is inflammable or explosive.
During operation, the power tool produces sparks, which may ignite
emitted vapours.
• Do not use cut-off wheels for grinding. The cut-off wheels are used to
cut with its face, while grinding with lateral surface of such a cut-off wheel
threatens with its damages and puts the operate in danger of injuries.
