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.

• 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.

Additional specific safety guidelines for cutting with a cut-off wheel

• Always prevent a cut-off wheel from seizure and avoid excessive 

pressure. Do not make too deep cuts. 

The overload of a cut-off wheel 

increases its load and tendency for seizure or locking, and thus may result 
in recoil or breaking of a cut-off wheel.

• Avoid areas in front of and behind a rotating cut-off wheel. 

When 

a cut-off wheel is moved onto a workpiece away from the operator, it may 
cause the power tool to kick back as a result of recoil, with a rotating cut-
off wheel pointing directly towards the operator.

• When a cut-off wheel seizes or you take a break from work, switch 

off the power tool and wait until it comes to a complete stop. Do 
not attempt to remove a rotating cut-off wheel from a cutting 
place, since it may cause recoil. 

 Find and eliminate a cause of seizure.

• Do not switch the power tool back on, if it is still sunk in a 

workpiece. Before you continue to cut, a cut-off wheel must reach 
its full rotational speed. 

Otherwise, a cut-off wheel may catch, spring 

back from a workpiece and cause recoil.

• Boards and large objects should be supported to reduce the risk 

of recoil caused by a seized cut-off wheel.

 Large objects may bend 

under their own weight. A workpiece should be supported from both 
sides, both near the cut line and its edge.

• Special caution should be exercised, when holes are cut in a wall 

or in confined spaces. 

 As a cut-off wheel sinks into a workpiece, it may 

cause the power tool to recoil, when it encounters a gas or water supply 
line, power conductors or other objects.

Specific safety guidelines for sanding with sandpaper

• Do not use too large sheets of sandpaper.  Always follow 

guidelines of a manufacturer, when the size of a sandpaper is 
selected. 

Sandpaper protruding beyond a grinding disc may cause 

injuries and result in locking and tearing of sandpaper, or recoil.

Specific safety guidelines for working with wire brushes

• It should always be remembered that pieces of wire are lost even 

during normal use. Do not overload wires by putting excessive 
pressure. 

Airborne pieces of wire may easily puncture thin clothing and/

or skin.

• If a guard is recommended to be used, prevent a brush from 

touching the guard. 

A brush diameter for plates and pots may increase 

due to the pressure and centrifugal forces.

Additional safety guidelines

• Before connecting to the power source, always make sure the 

supply voltage is compatible with the value specified on the 
nameplate of the tool.

• Before the grinder is connected, always check the power cord. In 

case of damage, have it repaired in an authorised workshop.

• Before all installation works, the plug should be taken out of the 

receptacle.

• Grinding tools should be checked before each use. A grinding 

tool must be correctly fastened and should rotate freely. As part 
of the test, the tool should be switched on with no load for at least
