Afterwards, tighten the bottom part of the auxiliary handle 

8

again by turning in clockwise direction.

The knurled surface of the depth stop 

9

 must face upward.

Changing the Tool



Wear protective gloves when changing the tool. 

The 

drill chuck can become very hot during longer work peri-
ods.

Keyless Chuck (GSB 19-2 RE)  (see figure B)

The drill spindle is locked when the On/Off switch 

6

 is not 

pressed. This makes quick, convenient and easy changing of 
the tool in the drill chuck possible.

Open the keyless chuck 

1

 by turning in rotation direction 



, 

until the tool can be inserted. Insert the tool.

Firmly tighten the collar of the keyless chuck 

1

 by hand in ro-

tation direction 



 until the locking action (“click”) is no longer 

heard. This automatically locks the chuck.

The locking is released again to remove the tool when the col-
lar is turned in the opposite direction.

Keyless Chuck (GSB 780) (see figure C)

Hold the rear sleeve 

12

 of the keyless chuck 

1

 tight and turn 

the front sleeve 

11

 in rotation direction 



, until the tool can 

be inserted. Insert the tool.

Hold the rear sleeve 

12

 of the keyless chuck 

1

 tight and firmly 

turn the front sleeve 

11

 in rotation direction 



 by hand until 

the locking action is no longer heard. This automatically locks 
the drill chuck.

The locking is released again to remove the tool when the 
front sleeve 

11

 is turned in the opposite direction.

Key Type Drill Chuck (see figure D)

Open the key type drill chuck 

14

 by turning until the tool can 

be inserted. Insert the tool.

Insert the chuck key 

13

 into the corresponding holes of the 

key type drill chuck 

14

 and clamp the tool uniformly.

Screwdriver Tools (see figure E)

When working with screwdriver bits 

15

, a universal bit holder 

16

 should always be used. Use only screwdriver bits that fit 

the screw head.

For driving screws, always position the “Drilling/Impact Drill-
ing” selector switch 

2

 to the “Drilling” symbol.

Replacing the Drill Chuck



Before any work on the machine itself, pull the mains 
plug.

Removing the Drill Chuck (see figure F)

Disassemble the auxiliary handle and set the gear selector 

7

to the centre position between the 1st and 2nd gear.

Insert a steel pin with a diameter of Ø 4 mm and approx. 
50 mm of length into the drill hole on the spindle neck in order 
to lock the drill spindle.

Clamp the short end of an Hex key 

17

 into the keyless chuck 

1

.

Place the machine on a stable surface (e. g. a workbench). 
Hold the machine firmly and loosen the keyless chuck 

1

 by 

turning the Hex key 

17

 in rotation direction 



. Loosen a tight-

seated keyless chuck by giving the long end of the Hex key 

17

a light blow. Remove the Hex key from the keyless chuck and 
completely unscrew the keyless chuck.

For machines with key chuck, disassembly is carried out anal-
ogous as described above.

For machines with keyless chuck, an open-end spanner (size 
19 mm) can be applied to the drill chuck instead of an Hex 
key.

Mounting the Drill Chuck (see figure G)

The keyless chuck/key type drill chuck is mounted in reverse 
order.



Remove the steel pin from the drill hole on the spindle 
neck after mounting is completed.

The drill chuck must be tightened with a tightening 
torque of approx. 50 – 55 Nm.

Dust/Chip Extraction



Dusts 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 dusts can cause 
allergic reactions and/or lead to respiratory infections of 
the user or bystanders.
Certain dusts, such as oak or beech dust, are considered 
as carcinogenic, especially in connection with wood-treat-
ment additives (chromate, wood preservative). Materials 
containing asbestos may only be worked by specialists.
– 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 mate-
rials to be worked.



Prevent dust accumulation at the workplace. 

Dusts can 

easily ignite.

Operation

Starting Operation



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.

Reversing the rotational direction (see figure H)



Actuate the rotational direction switch 3 only when the 
machine is at a standstill.

The rotational direction switch 

3

 is used to reverse the rota-

tional direction of the machine. However, this is not possible 
with the On/Off switch 

6

 actuated.

Right rotation:

 For drilling and driving in screws, push the ro-

tational direction switch 

3

 downward on the left side and at 

the same time upward on the right side.

Left rotation:

 For loosening and unscrewing screws and 

nuts, push the rotational direction switch 

3

 upward on the left 

side and at the same time downward on the right side.
