Inserting Drilling Tools without SDS-plus 
(GBH 2-26 E/RE/DE/DRE)
Note: 

Do not use tools without SDS-plus for hammer drilling 

or chiselling! Tools without SDS-plus and their drill chucks are 
damaged by hammer drilling or chiselling.

– Insert a key type drill chuck 

19

 (see “Changing the Key

Type Drill Chuck”, page 16).

– Open the key type drill chuck 

19

 by turning until the tool 

can be inserted. Insert the tool.

– Insert the chuck key into the corresponding holes of the

key type drill chuck 

19

 and clamp the tool uniformly.

– GBH 2-26 E/RE: Set the selector switch 

16

 to the “Drilling”

symbol.

– GBH 2-26 DE/DRE: Turn the mode selector switch 

11

 to 

the “drilling” position.

Removing Drilling Tools without SDS-plus 
(GBH 2-26 E/RE/DE/DRE)

– Turn the sleeve of the key type drill chuck 

19

 with the drill 

chuck key in anticlockwise direction until the drilling tool 
can be removed.

Inserting Drilling Tools without SDS-plus (GBH 2-26 DFR) 
(see figure H)
Note: 

Do not use tools without SDS-plus for hammer drilling 

or chiselling! Tools without SDS-plus and their drill chucks are 
damaged by hammer drilling or chiselling.

– Insert the quick change keyless chuck 

1

.

– Firmly hold the retaining ring 

23

 of the quick change 

chuck. Open the tool holder by turning the front sleeve 

22

until the tool can be inserted. Tightly hold the retaining ring 

23

 and firmly turn the front sleeve 

22

 in the direction of the 

arrow until a distinct latching noise can be heard.

– Check the tight seating by pulling the tool.

Note: 

If the tool holder was opened to the stop, then the latch-

ing noise possibly may be heard while closing the tool holder 
and the tool holder will not close.
In this case, turn the front sleeve 

22

 once in the opposite di-

rection of the arrow. Afterwards, the tool holder can be 
closed (tightened) again.

– Turn the mode selector switch 

11

 to the “drilling” position.

Removing Drilling Tools without SDS-plus 
(GBH 2-26 DFR) (see figure I)

– Firmly hold the retaining ring 

23

 of the quick change 

chuck. Open the tool holder by turning the front sleeve 

22

in the direction of the arrow until the tool can be removed.

Dust Extraction with the Dust Extraction Attach-
ment (Accessory)



Dust from materials such as lead-containing coatings, 
some wood types, minerals and metal can be harmful to 
one’s health. Touching or breathing-in the dust can cause 
allergic reactions and/or lead to respiratory infections of 
the user or bystanders.
Certain dust, such as oak or beech dust, is considered car-
cinogenic, especially in connection with wood-treatment 
additives (chromate, wood preservative). Materials con-
taining asbestos may only be worked by specialists.

– As  far  as  possible,  use  a  dust extraction system suitable 

for the material.

– Provide for good ventilation of the working place.
– It is recommended to wear a P2 filter-class respirator.
Observe the relevant regulations in your country for the 
materials to be worked.



Prevent dust accumulation at the workplace. 

Dust can 

easily ignite.

Mounting the Dust Extraction Attachment (see figure J)

For dust extraction, the dust extraction attachment (accesso-
ry) is required. When drilling, the dust extraction attachment 
retracts so that the attachment head is always close to the 
surface at the drill hole.

– Press the button for depth stop adjustment 

12

 and remove 

the depth stop 

13

. Press button 

12

 again and insert the

dust extraction attachment into the auxiliary handle 

14

from the front.

– Connect an extraction hose (diameter 19 mm, accessory) 

to the extraction sleeve 

24

 of the dust extraction attach-

ment.

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.

Adjusting the Drilling Depth on the Dust Extraction
Attachment (see figure K)

The required drilling depth

X

 can also be adjusted when the 

dust extraction attachment is mounted.

– Insert the SDS-plus drilling tool to the stop into the SDS-

plus tool holder 

3

. Otherwise, the movability of the SDS-

plus drilling tool can lead to incorrect adjustment of the 
drilling depth.

– Loosen the wing bolt 

28

 on the dust extraction attach-

ment.

– Without switching the power tool on, apply it firmly to the 

drilling location. The SDS-plus drilling tool must face 
against the surface.

– Position the the guide pipe 

29

 of the dust extraction at-

tachment in its holding fixture in such a manner that the 
head of the dust extraction attachment faces against the 
surface to be drilled. Do not slide the guide pipe 

29

 further 

over the telescopic pipe 

27

 of the dust extraction attach-

ment than required, so that as much as possible of the 
scale 

27

 on the telescopic pipe remains visible.

– Retighten the wing bolt 

28

 again. Loosen the clamping

screw 

25

 on the depth stop of the dust extraction attach-

ment.

– Move the depth stop 

26

 on the telescopic pipe 

27

 in such 

a manner that the clearance

X

 shown in the figure corre-

sponds with the required drilling depth.

– Tighten the clamping screw 

25

 in this position.
