is to be shielded as much as possible. The guard is intended to
protect the operator from debris and accidental contact with the
cutting disc.
• Only diamond cutting discs should be used. The fact that an
accessory can be attached to a power tool does not guarantee its
safe use.
• The permissible speed of the working tool used must not be less
than the maximum speed indicated on the power tool. A work tool
rotating faster than the permissible speed may break and parts of
the tool may splinter.
• Diamond cutting discs must only be used for the work intended
for them. For example, never use the side surface of a cutting
disc for grinding. Cutting discs are designed to remove material
with the edge of the disc. The effect of lateral forces can cause
the wheel of this type to break.
• Always use undamaged clamping flanges of the correct size for
the selected cutting disc. The correct flanges support the cutting
disc and thus reduce the risk of breakage.
• The outer diameter and thickness of the working tool must
correspond to the dimensions of the power tool. Work tools with
incorrect dimensions cannot be sufficiently shielded or inspected.
• Discs, washers, flanges and other accessories must fit exactly on
the spindle of the power tool. Work tools that do not fit exactly on
the spindle of the power tool will rotate unevenly, vibrate very
strongly and may cause loss of control of the power tool.
• Under no circumstances should damaged working tools be used.
Inspect work tools for chips and cracks before each use. If a
power tool or work tool falls, check it for damage or use another
undamaged work tool. Once the power tool has been checked
and fixed, start the power tool and leave it running for one minute
at the highest speed, taking care to keep the user and other
bystanders out of the zone of the rotating power tool. Damaged
tools usually break during this test.
• Personal protective equipment must be worn. Depending on the
type of work, wear a protective mask covering the entire face,
eye protection or safety goggles. If necessary, use a dust mask,
hearing protection, protective gloves or a special apron to protect
against small particles of abraded and machined material. Protect
your eyes from airborne foreign bodies generated during work. A
dust mask and respiratory protection must filter out dust
generated during work. Exposure to noise over a prolonged
period may lead to hearing loss.
• Ensure that bystanders are at a safe distance from the power
tool's reach zone. Anyone in the vicinity of a working power tool
must use personal protective equipment. Workpiece splinters or
broken work tools can splinter and cause injury even outside the
immediate reach zone.
• During work where a power tool could encounter
• on hidden electrical wires or on your own cord, hold it only by the
insulated handle. On contact with live wires, all metal parts of the
power tool will also be live and may cause an electric shock to
the operator.
• Keep the mains cable away from rotating work tools. If you lose
control of the tool, the mains cable could be cut or pulled in and
your hand or whole hand could get caught in a rotating work tool.
• Never put the power tool down before the work tool has come to
a complete stop. A rotating tool may come into contact with the
surface on which it is put down, so you could lose control of the
power tool.
• Do not carry a power tool while it is in motion. Accidental contact
between clothing and a rotating power tool may cause the tool to
be pulled in and drill the power tool into the operator's body.
• Clean the ventilation slots of the power tool regularly. The motor
fan draws dust into the housing and a large accumulation of
metal dust can cause an electrical hazard.
• Do not use the power tool near flammable materials. Sparks may
ignite them.
• Do not use tools that require liquid coolants. The use of water or
other liquid coolants can lead to electric shock.
Rejection and relevant safety tips
Kickback is the sudden reaction of a power tool to the blockage or
obstruction of a rotating work tool. The snagging or blocking leads to a
sudden stop of the rotating work tool. The uncontrolled power tool will
thus be jerked in the direction opposite to the direction of rotation of the
working tool.
When, for example, the grinding wheel becomes jammed or stuck in
the workpiece, the immersed edge of the grinding wheel can become
blocked and cause it to fall out or eject. The movement of the grinding
wheel (towards or away from the operator) is then dependent on the
direction of movement of the wheel at the point of blockage. In addition,
grinding wheels can also break.
Recoil is a consequence of improper or incorrect use of the power tool.
It can be avoided by taking the appropriate precautions described
below.
• The power tool should be held firmly, with the body and hands in
a position to soften the recoil. If an auxiliary handle is included as
part of the standard equipment, it should always be used in order
to have as much control as possible over the recoil forces or the
recoil moment at start-up. The operator can control the jerk and
recoil phenomena by taking appropriate precautions.
• Never hold hands near rotating work tools. The working tool may
injure your hand due to recoil.
• Keep away from the range zone where the power tool will move
during recoil. As a result of recoil, the power tool moves in the
opposite direction to the movement of the grinding wheel at the
point of blockage.
• Be particularly careful when machining corners, sharp edges, etc.
Prevent work tools from being deflected or becoming jammed. A
rotating work tool is more susceptible to jamming when
machining angles, sharp edges or if it is kicked back. This can
become a cause of loss of control or kickback.
• Do not use wood discs, diamond segment discs with a peripheral
gap of more than 10 mm or toothed discs. Work tools of this type
often cause recoil or loss of control of the power tool.
• Avoid jamming of the cutting disc or too much pressure. Do not
make excessively deep cuts. Overloading the cutting disc
increases the load on the blade and its tendency to jam or block
and thus the possibility of discarding or breaking.
• If the cutting disc becomes jammed or if there is an interruption in
operation, switch off the power tool and wait until the disc has
fully
• will stop. Never attempt to pull the still moving disc out of the
cutting area as this may cause recoil. The cause of the jamming
must be detected and removed.
• Do not restart the power tool while it is in the material. The cutting
wheel should reach its full speed before continuing to cut.
Otherwise, the grinding wheel may catch, jump off the workpiece
or cause recoil.
• Plates or large objects should be supported before machining to
reduce the risk of kickback caused by a jammed disc. Large
workpieces may bend under their own weight. The workpiece
should be supported on both sides, both near the cutting line and
at the edge.
• Take special care when cutting holes in walls or operating in
other invisible areas. The cutting disc plunging into the material
may cause the tool to recoil if it encounters gas pipes, water
pipes, electrical cables or other objects.
NOTE: The device is for indoor use
Despite the use of an inherently safe design, the use of safety
measures and additional protective measures, there is always a
residual risk of injury during work.
