– 

Wear suitable personal protective equipment:

 Ear protec-

tion, protective goggles, dust mask for work that generates 

dust and protective gloves when changing tools, sturdy 

shoes.

2.8  Other risks

Even in cases where the machine is used correctly and all rele-

vant safety instructions have been adhered to, the design engi-

neering of the machine and its operation mean that the follow-

ing safety risks may also arise:
–  Danger caused by the power cable.
–  A concentration of dust which is harmful to health when 

working in an area that is not sufficiently ventilated.

–  Injuries caused by touching electrified parts when removing 

the machine or its parts if the plugs on the power cable have 

not been removed from the socket.

–  You must only use original spare parts.

3  Information about noise level and 

vibrations

The values have been measured in conformity with EN 60745.

EBU 230-26 HD

Acoustic pressure level L

pA

 = 90.6 dB (A).

Acoustic power level L

wA

 = 101.6 dB (A).

In accuracy of measurements K = 3.0 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.

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.

2.4  Additional safety instructions for 

cutting-off operations:

a) 

Do  not “jam” the cut-off wheel or apply excessive pres-

sure. Do  not attempt to make an excessive depth of cut.

Overstressing the wheel increases the loading and suscepti-

bility 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. 

Never attempt to remove the cut-off wheel from the cut 

while the wheel is in motion otherwise kick-back may oc-

cur.

 Investigate 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.

2.5  Safety Warnings Specific for Sanding 

Operations:

a) 

Do  not use excessively oversized sanding disc paper. 

Follow 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.

2.6  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.

2.7  Further safety instructions

–  Check the plug and cable on a regular basis and, if they are 

damaged, have them replaced by an authorised customer 

service workshop.

–  The switch must be in the OFF position before you connect it 

to the mains.

–  Always guide the power cable from the tool to the rear. Never 

pull hard on the power cable and never place it on or guide it 

over any sharp edges.

–  Only work in a safe and stable position.
–  Do not work in damp environments.
