5.15. Do not use work tools that require the application of coolants. The use of water or other coolants
may cause electric shock.
6. Kickback and tips for avoiding it.
6.1. The sudden reaction of the machine is kicked off as a result of locking or blocking the rotating
tool, abrasive disk, rubber subwoofer, wire brush and more. The jamming or blocking causes the tool
to rotate abruptly, as a result of which the angle grinder receives a strong acceleration in the direction
opposite to the direction of rotation of the tool at the locking point and becomes unmanageable. If, for
example, an abrasive disk is wedged or blocked in the workpiece, the edge of the disc that touches
the workpiece can bend and the disc breaks or a kickback occurs. In this case, the disc is accelerating
towards the machine operator or in the opposite direction, depending on the direction of rotation of the
disc and the place of engagement. In such cases the abrasive discs may break. Retract occurs as a
result of improper or incorrect use of the angle grinder. Its occurrence can be prevented by following
the appropriate precautions described below.
6.2. Keep the angle grinder firmly and hold your hands and body in such a position as to counteract a
possible kickback. If the angle grinder has an auxiliary handle, always use it to better control it when
it comes to kickback or when it comes to reaction moments during switch-on. If you take appropriate
precautions beforehand, you can control the machine if a kickback or strong reaction times occur.
6.3. Never place your hands near rotating work tools. If a kickback occurs, the tool may hurt you.
6.4. Avoid standing in the area where the angle grinder will jump when a kickback occurs. The kick
moves the machine in a direction opposite to the direction of movement of the tool in the lock zone.
6.5. Work especially cautiously in areas of angles, sharp edges, etc. Avoid repulsion or jamming of
workpieces in the workpiece. In the case of angles or sharp edges, or when the rotating tool is sharply
repelled, there is an increased risk of jamming. This causes loss of machine control or kickback.
6.6. Do not use chain or jagged cutting sheets. Such work tools often cause a kickback or loss of
control over the angle grinder.
7. Special instructions for safe operation when grinding or cutting with abrasive discs
7.1. Use only the abrasive discs provided with your grinding wheel and the protective sleeve for the
abrasive disk used. Abrasive discs not designed for the angle grinder can not be shielded properly
and do not guarantee safe operation.
7.2. The guard must be securely attached to the angle grinder and positioned so as to provide
maximum safety, e.g. the abrasive disc must not be directed uncovered from the casing to the
machine operator. The casing should protect the machine operator from scrapping of scraped bits
and from entering into contact with the rotating abrasive disc.
7.3. The use of abrasive disks is only allowed for the purposes for which they are intended. For
example: never sand with the side of a cutting disc. Cutting discs are designed to remove material
with its edge. Side force application can break them.
7.4. Always use locking nuts that are in a flawless condition and conform to the size and shape of
the abrasive disc used. The lock nuts for the cutting discs may differ from those for grinding discs. In
some models, the locking nuts can also be used for grinding discs by screwing them on the opposite
side with their protruding part to the disc.
7.5. Do not use worn abrasive discs of larger angle grinders. Discs for larger machines are not
designed for high-speed rotation, with which the smaller ones can rotate and can break.
8. Special instructions for safe operation with cutting discs.
8.1. Avoid locking the blade or pinching it hard. Do not perform too deep cuts. Overloading the cutting
disc increases the risk of jamming or blocking it, and hence the occurrence of kickback or breakage
as it rotates.
8.2. Avoid standing in the area in front of and behind the rotating cutting disc. When the cutting disc
is in a plane with your body, in the event of a kickback, the angle grinder with the rotating disc may
bounce straight to you and hurt you.
8.3. If the cutting disc jammed or when it is interrupted, turn off the angle grinder and leave it only
after the disc has stopped rotating. Never try to remove the rotating disc from the cutting channel,
otherwise a kickback may occur. Determine and eliminate the reason for the jam.
8.4. Do not re-turn the angle grinder if the disc is in the cut-out. Prior to cutting carefully, wait for the
