Do not put the power tool aside, before the working tool comes to a 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 catch 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 locking or stopping of the rotating working tool.
The locking or catching results in sudden stopping of the rotating working tool. The power tool
without control will be jerked in the opposite direction to the working tool.
When the working tool stops or catches in the workpiece, its part sunk in the workpiece may seize and
recoil or reject. The movement of the working tool (towards or away from the operator) depends on the
movement of the working tool in a place, where it is seized. The working tool 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 working tool, where
it seizes.
Corners, sharp edges, etc. should be worked with special attention. Recoil or seizure 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.
Specific safety guidelines for grinding
Always use the grinding wheel intended for a given power tool and guard intended for a given
grinding wheel. Grinding wheels, which are not 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. An 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 tools 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.
