Check grinding tools before using. The 

grinding tool must be mounted properly 

and be able to move freely. Carry out a test 

run for at least one minute with no load. Do 

not use damaged, out-of-centre or vibrating 

grinding tools. 

Damaged grinding tools can 

burst and cause injuries.

Kickback stop

In case of a sudden drop in speed, 

e.g., caused by a jammed disc 

while cutting, the power supply to 

the motor is electronically inter-

rupted.

To 

restart the operation

, switch the On/Off 

switch 

3

 to the Off position and start the ma-

chine again.

Note: 

When the machine only runs with heavily 

reduced speed, the kickback stop feature has 

failed. The power tool must promptly be sent to 

an after-sales service agent for maintenance; ad-

dresses, see Section „After-sales Service and 

Customer Assistance“.

Restarting Protection

The restarting protection feature prevents un-

controlled restarting of the machine after an in-

terruption in the power supply.
To 

restart the operation

, switch the On/Off 

switch 

3

 to the Off position and start the ma-

chine again.

Reduced starting current

The electronic reduced starting current limits 

the power consumption when switching the tool 

on and enables operation from a 13 ampere 

fuse.

Note: 

When the machine runs with full speed af-

ter switching on, the reduced starting current, 

the restarting protection and the kickback stop 

features have failed. The power tool must 

promptly be sent to an after-sales service agent 

for maintenance; addresses, see Section „After-

sales Service and Customer Assistance“.

Working Advice

f

Exercise caution when cutting slots in 

structural walls; see Section “Information 

on Structures ”.

f

Clamp the workpiece if it does not remain 

stationary due to its own weight.

f

Do not strain the machine so heavily that it 

comes to a standstill.

f

After heavily straining the power tool, con-

tinue to run it at no-load for several minutes 

to cool down the cutting/grinding tool.

f

Grinding and cutting discs become very hot 

while working; do not touch until they have 

cooled.

Note: 

When not using for extended periods, pull 

the mains plug out of the socket outlet. When 

the mains plug is inserted and mains voltage is 

given, the power tool, even when switched off, 

still consumes a low amount of current.

Rough Grinding

f

Never use a cutting disc for roughing.

The best roughing results are achieved when 

setting the machine at an angle of 30 °  to 40 ° . 

Move the machine back and forth with moderate 

pressure. In this manner, the workpiece will not 

become too hot, does not discolour and no 

grooves are formed.

Flap Disc

With the flap disc (accessory), curved surfaces 

and profiles can be worked.
Flap discs have a considerably higher service 

life, lower noise levels and lower sanding tem-

peratures than conventional sanding sheets.

Cutting Metal

f

For cutting metal, always work with the pro-

tection guard for cutting 14.
