ing procedures or conditions and can be avoided by taking proper 

precautions as given below.

a) 

Maintain a firm grip on the power tool and position your 

body and arm to allow you to resist kickback forces. Always 

use an auxiliary handle, if provided, for maximum control 

over kickback or torque reaction during start‑up.

 The oper-

ator can control torque reactions or kick-back forces, if proper 

precautions are taken.

b) 

Never place your hand near the rotating accessory.

 Acces-

sory may kickback over your hand.

c) 

Do  not position your body in the area where power tool 

will move if kickback occurs.

 Kick-back will propel the tool 

in direction opposite to the wheel’s movement at the point of 

snagging.

d) 

Take special care when working corners, sharp edges etc. 

Avoid bouncing and snagging the accessory.

 Corners, sharp 

edges or bouncing have a tendency to snag the rotating ac-

cessory and cause loss of control or kickback.

e) 

Do not attach a saw chain woodcarving blade or toothed 

saw blade.

 Such blades create frequent kickback and loss of 

control.

Safety warnings specific for grinding and 

cutting‑off operations:

a) 

Use only wheel types that are recommended for your pow‑

er tool and the specific guard designed for the selected 

wheel.

 Wheels for which the power tool was not designed 

cannot be adequately guarded and are unsafe.

b) 

Use only the specific guard designed for the selected 

wheel. The guard must be securely attached to the pow‑

er tool and positioned for maximum safety, so the least 

amount of wheel is exposed towards the operator.

 The 

guard helps to protect the operator from broken wheel frag-

ments and accidental contact with the wheel.

c) 

Wheels must be used only for recommended applications. 

For example: do not grind with the side of cut‑off wheel.

Abrasive cut-off wheels are intended for peripheral grinding, 

side forces applied to these wheels may cause them to shat-

ter.

d) 

Always use undamaged wheel flanges that are of correct 

size and shape for your selected wheel.

 Proper wheel flang-

es support the wheel thus reducing the possibility of wheel 

breakage. Flanges for cut-off wheels may be different from 

grinding wheel flanges.

e) 

Do  not use worn down wheels from larger power tools.

Wheels intended for larger power tools are not suitable for 

the higher speed of a smaller tool and may burst.

Additional safety instructions for cutting‑off 

operations:

a) 

Do not “jam” the cut‑off wheel or apply excessive pressure. 

Do not attempt to make an excessive depth of cut.

 Over-

stressing the wheel increases the loading and susceptibility to 

twisting or binding of the wheel in the cut and the possibility 

of kickback or wheel breakage.

b) 

Do  not position your body in line with and behind the 

rotating wheel.

 When the wheel, at the point of operation, 

is moving away from your body, the possible kickback may 

propel the spinning wheel and the power tool directly at you.

c) 

When wheel is binding or when interrupting a cut for any 

reason, switch off the power tool and hold the power tool 

motionless until the wheel comes to a complete stop. Nev‑

er attempt to remove the cut‑off wheel from the cut while 

the wheel is in motion otherwise kick‑back may occur.

 In-

vestigate and take corrective action to eliminate the cause of 

wheel binding.

d) 

Do not restart the cutting operation in the workpiece. Let 

the wheel reach full speed and carefully reenter the cut.

The wheel may bind, walk up or kickback if the power tool is 

restarted in the workpiece.

e) 

Support panels or any oversized workpiece to minimise 

the risk of wheel pinching and kick‑back.

 Large workpieces 

tend to sag under their own weight. Supports must be placed 

under the workpiece near the line of cut and near the edge of 

the workpiece on both sides of the wheel.

f) 

Take extra caution when making a “pocket cut” into exist‑

ing walls or other blind areas.

 The protruding wheel may cut 

gas or water pipes, electrical wiring or objects that can cause 

kickback.

Safety Warnings Specific for Sanding 

Operations:

a) 

Do not use excessively oversized sanding disc paper. Fol‑

low manufacturers recommendations when selecting 

sanding paper.

 Larger sanding paper extending beyond the 

sanding pad presents a laceration hazard and may cause 

snagging, tearing of the disc or kickback.

Safety Warnings Specific for Wire Brushing 

Operations:

a) 

Be aware that wire bristles are thrown by the brush even 

during ordinary operation. Do not overstress the wires by 

applying excessive load to the brush.

 The wire bristles can 

easily penetrate light clothing and/or skin.

b) 

If the use of a  guard is recommended for wire brushing, 

do not allow any interference of the wire wheel or brush 

with the guard.

 Wire wheel or brush may expand in diameter 

due to work load and centrifugal forces.

Information about noise level and 

vibrations

Acoustic power level L

 = 96 dB (A).

In accuracy of measurements K = 3 dB (A).

ATTENTION! Noise is generated during work!
Use ear protection!

The emission values specified (vibration, noise) were measured in 

accordance with the test conditions stipulated in EN 60745 and are 

intended for machine comparisons. They are also used for making 

preliminary estimates regarding vibration and noise loads during 

operation.
The emission values specified refer to the main applications for 

which the power tool is used. If the electric power tool is used for 

other applications, with other tools or is not maintained sufficient-

ly prior to operation, however, the vibration and noise load may be 

higher when the tool is used.
Take into account any machine idling times and downtimes to esti-

mate these values more accurately for a specified time period. This 

may significantly reduce the load during the machine operating 

period.

Double insulation

To ensure maximum safety of the user, our tools are designed and 

built to satisfy applicable European standards (EN standards). Tools 

with double insulation are marked by the international symbol of 

a double square. These tools must not be grounded and a two-wire 

cable is sufficient to supply them with power. Tools are shielded in 

accordance with EN 55014.

Use

The machine is designed for splitting, roughing and brushing met-

al and stone materials without the use of water. For cutting stone, 

a cutting guide is required.
The user himself is liable for any improper use.
