DETAILED SAFETY REGULATIONS
ANGLE GRINDER, SAFETY WARNINGS
Safety guidelines for grinding, sanding with sandpaper, working
with wire brushes and cutting using the grinding wheel.
• This power tool can be used as a regular grinder, sander for
sanding with sandpaper, grinder for grinding with wire brushes
and for cutting with a cut-off wheel. Observe all safety guidelines,
instructions, descriptions and data provided with the power tool.
Failure to observe the following recommendations may cause danger of
electric shock, fire and/or serious injuries.
• This power tool cannot be used for polishing. When the power tool
is used for other works than it is designed for, it may contribute to hazards
and injuries.
• Do not use equipment, which is not designed and recommended
by the manufacturer specifically for this device. The fact that it can
be fastened to the power tool, does not guarantee safe operation.
• The permissible rotational speed of a working tool used cannot
be lower than the maximum rotational speed given on the power
tool.
A working tool rotating faster than the permissible speed may break
and its parts may chip off.
• The outside diameter and thickness of a working tool must
correspond to dimensions of the power tool. A working tool of
incorrect dimensions may not provide sufficient control and covering of
the power tool.
• Working tools with threaded inserts must perfectly fit the thread
in the spindle. In case of working tools that are fastened using
a flange, the hole diameter of a working tool must fit the flange
diameter.
Working tools, which cannot be precisely seated in the power
tool, rotate unevenly, vibrate heavily and may result in loss of control over
the power tool.
• Under no circumstances, should damaged working tools be used.
Before the power tool is used, accessories such as cut-off wheels
should be checked for chips and cracks, grinding wheels should
be checked for cracks, abrasion or heavy wear, while wire brushes
for loose or broken wires. When the power tool or a working tool is
dropped, it must be checked for damage or another, undamaged
tool should be used. If a working tool is checked and fastened,
the power tool should be switched on for a minute at the highest
speed, paying attention so that the operator and bystanders are
beyond the zone of the rotating tool.
Damaged working tools often
break in this test period.
• Always wear personal protective equipment. Depending on a
type of work, a full face mask, eye protection or safety glasses
should be worn. A dust mask, ear protection, protective gloves
or a special apron protecting against small particles of abrasive
material and workpiece should be worn, if needed.
Protect your
eyes against airborne foreign bodies occurring during operation. A dust
mask and protective mask for the respiratory system must filter dust
occurring during work. The influence of noise for a longer period of time
may lead to deterioration of the hearing.
• Always make sure bystanders are in a safe distance from the
power tool reach zone. All people staying in the vicinity of the
operating power tool must use personal protective equipment.
Chips of a workpiece or broken working tools may chip off and cause
injuries also beyond the direct reach zone.
• When works are performed, during which the power tool may
encounter hidden electric conductors or own power cord, the
power tool should be held by the isolated surfaces of the handle.
A contact with the power mains network may transfer voltage onto metal
parts of the power tool, which may result in electric shock.
• The power cord must be kept away from the rotating working
tools. When the control over the tool is lost, the power cord may be cut
or caught, and your hand or the entire arm may get into the rotating
working tool.
GB
• Do not put the power tool aside, before the working tool comes to
complete stop. The rotating working tool may come in contact with a
surface, which it is put aside onto, and you may lose control over the tool.
• Do not carry the power tool, which is in motion. An accidental
contact with the rotating working tool may caught in your clothes and
drill into an operator’s body.
• Clean ventilation slots of the power tool on a regular basis. The
motor blower sucks dust into the casing, while large accumulation of
metal dust may cause electric hazard.
• Do not use the power tool near flammable materials. Sparks may
cause ignition.
• Do not use tools, which require liquid cooling agents. The use of
water or other cooling agents may cause electric shocks.
Recoil and proper safety guidelines
• Recoil is a sudden reaction of the power tool to seizure or blocking
of a rotating working tool, such a grinding wheel, cut-off wheel or a
wire brush, etc.
The seizure and blocking may suddenly stop a rotating working
tool. The power tool without control will be jerked in the opposite
direction to the working tool.
When the grinding wheel stops or catches in the workpiece, an
edge od the grinding wheel immersed in the workpiece may lock
and cause recoil or rejection. The movement of the grinding wheel
(towards or away from the operator) depends on the movement of
the grinding wheel in a place, where it is locked. The grinding wheels
may also break.
Recoil is a consequence of incorrect operation of the power tool. This
can be avoided by observing the following precautions.
• The power tool must be held firmly, while your body and hands
should be positioned to alleviate recoil. If the additional handle is
included as standard equipment, it should be used at all times to
provide the highest control over recoil forces or rejecting moment
during start-up.
An operator can take control of recoil and jerking by
taking proper precautions.
• Never hold your hands in the vicinity of rotating working tools. A
working tool may injure your hand as a result of recoil.
• 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.
