Integrated Dust Extraction with Dust Box 

(see figures C1 – C4)

Before assembling the dust box 

6

, pull out the plastic slider 

13

. Place the dust box 

6

 onto the extraction outlet 

14

 and al-

low it to engage. Make sure that the plastic slider 

13

 engages 

in the holder 

12

.

To empty the dust box

6

, press the latching levers

15

 on the 

side of the dust box (

n

). Pull off the dust box toward the bot-

tom (

o

).

Before opening the dust box 

6

, it is recommended to loosen 

the dust from the filter element by gently striking it against a 

firm support (as shown in the figure).
Grasp the dust box 

6

 by the recessed grip, fold the filter ele-

ment 

16

 upward and empty the dust box. Clean the thin 

plates of the filter element 

16

 with a soft brush.

External Dust Extraction (see figure D)

Slide the extraction adapter

17

 onto the outlet piece

14

. En-

sure that the latching levers of the extraction adapter engage. 

The extraction adapter

17

 accepts a vacuum hose with a di-

ameter of 19 mm.
For removal of the extraction adapter

17

, press the latching 

levers together at the rear and pull the extraction adapter off.
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.

Internal Dust Extraction with Dust Bag (see figure E)

For small sanding jobs, a dust bag (accessory) 

19

 can be con-

nected.
Before mounting the dust bag 

19

, pull out the plastic slider 

13

. Slide the dust-bag sleeve firmly over the extraction outlet 

14

. Pay attention that the plastic slider 

13

 engages in the 

holder intended for it on the dust bag 

19

.

To maintain optimum dust collection, empty the dust bag 

19

in good time.

Auxiliary Handle

The auxiliary handle 

1

 enables convenient handling and opti-

mal distribution of power, especially at high removal rates.
Fasten the auxiliary handle 

1

 with screw 

2

 to the casing.

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.

Switching On and Off

To 

start

 the machine, press the On/Off switch 

4

 and keep it 

pressed.
To lock the 

pressed

 On/Off switch 

4

, press the lock-on button 

5

.

To 

switch off

 the machine, release the On/Off switch 

4

 or 

when it is locked with the lock-on button 

5

, briefly press the 

On/Off switch 

4

 and then release it.

Preselecting the Orbital Stroke Rate 

(GEX 125 AC/GEX 150 AC)

With the thumbwheel for preselection of the orbital stroke 

rate 

3

, you can preselect the required orbital stroke rate, even 

during operation.

The required stroke rate depends on the material and the 

working conditions and can be determined through practical 

testing.
The constant electronic control keeps the stroke rate almost 

constant under no-load or load conditions and ensures a uni-

form working performance.
After longer periods of working at low stroke rate, allow the 

machine to cool down by running it for approx. 3 minutes at 

maximum stroke rate with no load.

Sanding Plate Brake

An integrated sanding plate brake reduces the stroke rate 

when running at no-load so that scoring is prevented when 

placing the machine onto the workpiece.
If the no-load stroke rate continuously increases over the 

course of time, then the sanding plate is damaged and must 

be replaced or the sanding plate brake is worn. A worn sand-

ing plate brake must be replaced by an authorised after-sales 

service agent for Bosch power tools.

Working Advice

f

Before any work on the machine itself, pull the mains 

plug.

f

Wait until the machine has come to a standstill before 

placing it down. 

Sanding Surfaces

Switch the machine on, place it with the complete sanding 

surface on the surface to be worked and move the machine 

with moderate pressure over the workpiece.
The removal capacity and the sanding pattern are mainly de-

termined by the selection of the sanding sheet, the preselect-

ed orbital stroke rate (GEX 125 AC/GEX 150 AC) and the ap-

plied pressure.
Only flawless sanding sheets achieve good sanding capacity 

and extend the service life of the machine.
Pay attention to apply uniform sanding pressure; this increas-

es the working life of the sanding sheets.
Intensifiying the sanding pressure does not lead to an in-

crease of the sanding capacity, but to increased wear of the 

machine and the sanding sheet.
A sanding sheet that has been used for metal should not be 

used for other materials.
Use only original Bosch sanding accessories.

Rough Sanding

Attach a sanding sheet with coarse grain.
Apply only light pressure to the machine so that it runs at a 

higher stroke rate and high material removal is achieved.

1 – 2

Low stroke rate

3 – 4

Medium stroke rate

5 – 6

High stroke rate
