NOTE: BEFORE THE POWER TOOL IS USED FOR THE FIRST TIME, READ
THIS INSTRUCTION MANUAL AND KEEP IT FOR FUTURE REFERENCE.
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.
• 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.
