Bosch Power Tools



Do not restart the cutting operation in the workpiece. 
Let the wheel reach full speed and carefully re-enter 
the cut. 

The wheel may bind, walk up or kickback if the 

power tool is restarted in the workpiece.



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

Large work-

pieces 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.



Use extra caution when making a “pocket cut” into ex-
isting 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



Do not use excessively oversized sanding disc paper. 
Follow manufacturers recommendations, when select-
ing sanding paper. 

Larger sanding paper extending be-

yond the sanding pad presents a laceration hazard and 
may cause snagging, tearing of the disc, or kickback.

Safety warnings specific for wire brushing operations



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.



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.

Additional safety warnings

Wear safety goggles.



Use suitable detectors to determine if utility lines are 
hidden in the work area or call the local utility company 
for assistance. 

Contact with electric lines can lead to fire 

and electric shock. Damaging a gas line can lead to explo-
sion. Penetrating a water line causes property damage or 
may cause an electric shock.



Release the On/Off switch and set it to the off position 
when the power supply is interrupted, e. g., in case of a 
power failure or when the mains plug is pulled. 

This pre-

vents uncontrolled restarting.



Do not touch grinding and cutting discs before they 
have cooled down. 

The discs can become very hot while 

working.



Secure the workpiece. 

A workpiece clamped with clamp-

ing devices or in a vice is held more secure than by hand.

Products sold in GB only:

 Your product is fitted with a 

BS 1363/A approved electric plug with internal fuse 
(ASTA approved to BS 1362).
If the plug is not suitable for your socket outlets, it should 
be cut off and an appropriate plug fitted in its place by an 
authorised customer service agent. The replacement plug 
should have the same fuse rating as the original plug.

The severed plug must be disposed of to avoid a possible 
shock hazard and should never be inserted into a mains 
socket elsewhere.

Products sold in AUS and NZ only:

 Use a residual current 

device (RCD) with a rated residual current of 30 mA or 
less.

Product Description and Specifications

Read all safety warnings and all instruc-
tions. 

Failure to follow the warnings and in-

structions may result in electric shock, fire 
and/or serious injury.

While reading the operating instructions, unfold the graphics 
page for the machine and leave it open.

Intended Use

The machine is intended for cutting, roughing and brushing of 
metal and stone materials without the use of water.
For cutting with bonded abrasives, a special cutting guard 
(accessory) must be used.
When cutting in stone, provide for sufficient dust extraction.
With approved sanding tools, the machine can be used for 
sanding with sanding discs.
