Bosch Power Tools

Observe the relevant regulations in your country for the 

materials to be worked.

f

Prevent dust accumulation at the workplace. 

Dusts can 

easily ignite.

f

When working without dust extraction, always mount 

plug 2. 

Fragments of the workpiece or of a broken acces-

sory may fly away and cause injury beyond the immediate 

area of operation.

Connecting the Dust Extraction (see figure G)

Pull plug 

2

 out of vacuum connection 

20

. Mount elbow 

19

 and 

vacuum hose 

18

 (accessories) together. Insert elbow 

19

 into 

vacuum connection 

20

.

Swing out the holder 

6

 for the vacuum hose and clamp the 

vacuum hose 

18

 in the holder.

Connect vacuum hose 

18

 via adapter 

21

 (accessory) to the 

vacuum hose of a vacuum cleaner (accessory).
The machine can be plugged directly into the receptacle of a 

Bosch all-purpose vacuum cleaner with remote starting con-

trol. The vacuum cleaner starts automatically when the ma-

chine is switched on.
The vacuum cleaner must be suitable for the material being 

worked.
When vacuuming dry dust that is especially detrimental to 

health or carcinogenic, use a special vacuum cleaner.

Operation

Starting Operation

f

Observe correct mains voltage! The voltage of the pow-

er source must agree with the voltage specified on the 

nameplate of the machine. Power tools marked with 

230 V can also be operated with 220 V.

When operating the machine with power from mobile genera-

tors that do not have sufficient reserve capacity or are not 

equipped with suitable voltage control with starting current 

amplification, loss of performance or untypical behavior can 

occur upon switching on.

Please observe the suitability of the power generator being 

used, particularly with regard to the mains voltage and fre-

quency.

Switching On and Off

To 

start

 the power tool, push the On/Off switch 

1

 forwards.

To 

lock

 the On/Off switch 

1

, press the On/Off switch 

1

 down 

at the front until it latches.
To 

switch off

 the power tool, release the On/Off switch 

1

 or, 

if it is locked, briefly push down the back of the On/Off switch 

1

 and then release it.

f

Check the diamond cutting discs before use. The dia-

mond cutting disc(s) must be mounted properly and be 

able to rotate freely. Carry out a test run for at least one 

minute without any load. Do not use diamond cutting 

discs that are damaged, out-of-balance, or vibrate. 

Damaged diamond cutting discs can rupture and lead to in-

juries.

Working Advice

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, continue to run 

it at no-load for several minutes to cool down the acces-

sory.

f

The machine may only be used for dry cutting.

f

Diamond cutting discs become very hot during opera-

tion; do not touch them until they have cooled down.

Protect the cutting disc against impact, shock and grease. Do 

not subject the cutting disc to lateral pressure.
Do not brake coasting diamond cutting discs by applying side-

ward pressure.
For cutting expecially hard material, e. g., concrete with high 

pebble content, the diamond cutting disc can overheat and 

become damaged as a result. This is clearly indicated by cir-

cular sparking, rotating with the diamond cutting disc.

In this case, interrupt the cutting process and allow the dia-

mond cutting disc to cool by running the machine for a short 

time at maximum speed with no load.
Noticeable decreasing work progress and circular sparking 

are indications of a diamond cutting disc that has become 

dull. Briefly cutting into abrasive material (e. g. lime-sand 

brick) can resharpen the disc again.

Direction of Cut (see figure H)

Guide the machine as shown in the figure.

Maintenance and Service

Maintenance and Cleaning

f

Before any work on the machine itself, pull the mains 

plug.

f

For safe and proper working, always keep the machine 

and ventilation slots clean.

f

In extreme conditions, always use dust extraction as 

far as possible. Blow out ventilation slots frequently 

and install a residual current device (RCD). 

When work-

ing metals, conductive dust can settle in the interior of the 

power tool. The total insulation of the power tool can be im-

paired.

Please store and handle the accessory(-ies) carefully.
If the replacement of the supply cord is necessary, this has to 

be done by Bosch or an authorized Bosch service agent in or-

der to avoid a safety hazard.
If the machine should fail despite the care taken in manufac-

turing and testing procedures, repair should be carried out by 

an after-sales service centre for Bosch power tools.
In all correspondence and spare parts order, please always in-

clude the 10-digit article number given on the type plate of 

the machine.
