Do not carry the power tool at your side while the motor is 
running.

 Accidental contact with the rotating accessory 

could cause it to snag your clothing, pulling the accessory 
into your body.

Causes of kick-back and precautionary measures for 
the operator.

Kick-back is a sudden reaction of the power tool to a 
pinched or snagged rotating wheel, backing pad, brush or 
other accessory. 
Pinching or snagging causes rapid stalling of the rotating 
accessory, which in turn causes the uncontrolled power 
tool to be forced in the direction opposite to the acces-
sory’s rotation at the point of the binding.
For example, if an abrasive wheel is snagged or pinched 
by the workpiece, the edge of the wheel entering into 
the pinch point can dig into the surface of the material, 
causing the wheel to climb out or kick out.
The wheel may either jump towards or away from the 
operator, depending on the direction of the wheel’s rota-
tion at the point of pinching and can possibly also break.
Kickback is the result of power tool misuse and/or incor-
rect operating procedures or conditions and can be 
avoided by taking the proper precautions listed below.

Hold the power tool firmly and position your body and arms 
optimally to withstand any kickback forces. Always use the 
original auxiliary handle so that kickback forces or the 
starting torque can be mastered in the best possible way.

The operator can master the starting torque and kickback 
forces if suitable precautionary measures are taken.

Never place your hand near the rotating accessory.

 The 

accessory may kick back over your hand.

Do not position your body in the area where the power tool 
will move if kickback occurs.

 Kickback will propel the 

power tool in the direction opposite to the wheel’s 
movement at the point of snagging.

Take special care when machining corners, sharp edges, 
etc. Prevent the accessory from bouncing off or tilting.

 Cor-

ners, sharp edges or bouncing have a tendency to snag 
the rotating accessory and cause loss of control or kick-
back.

Do not attach a saw chain, wood-carving blade or circular 
saw blade.

 Blades of this kind cause frequent kickback or 

loss of control over the power tool.

Additional safety instructions, particularly for 
cutting operations

Avoid jamming the cutting wheel or applying excessive 
pressure. Do not attempt to make an excessive depth of cut. 

Overstressing the wheel increases the loading and sus-
ceptibility to twisting or binding in the cut and the likeli-
hood of kickback or wheel breakage.

Do not position yourself in line with and behind the rotating 
cutting wheel.

 When the cutting wheel, at the point of 

operation, is moving away from your body, a possible 
kickback may propel the cutting wheel and power tool 
directly at you.

Switch the power tool off if the cutting wheel blocks or if 
the cutting process is interrupted for some reason. Hold the 
power tool motionless until the cutting wheel has come to 
a complete stop. Never attempt to remove the cutting wheel 

from the cut while the wheel is still moving, otherwise kick-
back may occur.

 Investigate and take corrective action to 

eliminate the cause of the wheel binding.

Do not restart the cutting operation if the cutting wheel is 
in the workpiece. Let the cutting wheel reach full speed and 
then carefully reenter the cut.

 The cutting wheel may bind, 

jump out or kick back if the power tool is restarted with 
the cutting wheel in the workpiece.

Support the panels or any oversized workpiece to minimize 
the risk of wheel pinching or kickback.

 Large workpieces 

tend to sag under their own weight. Supports must be 
placed under the workpiece near the line of cut on both 
sides of the cutting wheel and at the ends of the work-
piece.

Use extra caution during “plunge cuts" in walls or other 
blind areas.

 The penetrating cutting wheel may cut gas or 

water conduits, electrical wiring or objects that could 
cause kickback.

Safety instructions, particularly for sanding work 
with a sanding disc.

When sanding, do not use an excessively oversized sanding 
disc. Follow the manufacturer’s recommendations when 
selecting sanding discs.

 Sanding discs larger than the 

backing pad present a laceration hazard; they can tear, 
cause snagging, rip off from the backing pad or cause 
kickback.

Special safety instructions for sanding work with 
wire brushes.

Be aware that wire bristles are thrown by the brush even 
during normal operation. Do not overstress the wire bristles 
by applying excessive load to the brush.

 The wire bristles 

can easily penetrate light clothing and/or the skin.

If the use of a guard is stipulated for sanding with wire 
brushes, do not allow the wire bristles to contact the guard.

The wire brush may expand in diameter due to the work 
load and centrifugal forces.
 

Before putting into operation, check the mains connection 
and the mains plug for damage.

The value of the estimated weighted acceleration 
obtained in the laboratory can serve for predicting the 
exposure to vibration. During work, weighted accelera-
tions will be dependent on the particular application, and 
deviation from this laboratory value can occur.

Intended use of the power tool:

hand-guided angle grinder for commercial use, for dry-
sanding/grinding and cutting metal and stone in weather-
protected environments using the application tools and 
accessories recommended by FEIN.
This machine is also intended to be powered by a.c. gen-
erators with sufficient power output that correspond 
with ISO 8528, design class G2. Compliance with this 
Standard in particular is not given when the so-called dis-
tortion factor exceeds 10%. When in doubt, inform 
yourself about the generator in use.
