Noise/Vibration Information

Sound emission values determined according to 
EN 60745-2-6.

Typically the A-weighted noise levels of the product are: 
Sound pressure level 92.5 dB(A); Sound power level 
103.5 dB(A). Uncertainty K = 3 dB.

The vibration level given in this information sheet has been 
measured in accordance with a standardised test given in 
EN 60745 and may be used to compare one tool with anoth-
er. It may be used for a preliminary assessment of exposure.
The declared vibration emission level represents the main ap-
plications of the tool. However if the tool is used for different 
applications, with different accessories or insertion tools or is 
poorly maintained, the vibration emission may differ. This 
may significantly increase the exposure level over the total 
working period.
An estimation of the level of exposure to vibration should also 
take into account the times when the tool is switched off or 
when it is running but not actually doing the job. This may sig-
nificantly reduce the exposure level over the total working 
period.
Identify additional safety measures to protect the operator 
from the effects of vibration such as: maintain the tool and the 
accessories, keep the hands warm, organisation of work pat-
terns.

Assembly



Before any work on the machine itself, pull the mains 

plug.

Auxiliary Handle



Operate your machine only with the auxiliary handle 

14.

Changing the position of the auxiliary handle 

(see figure A)

The auxiliary handle 

14

 can be set to any position for a secure 

and low-fatigue working posture.

– Turn the bottom part of the auxiliary handle 

14

 in counter-

clockwise direction and swivel the auxiliary handle 

14

 to 

the desired position. Then retighten the bottom part of the 
auxiliary handle 

14

 by turning in clockwise direction.

Pay attention that the clamping band of the auxiliary 
handle is positioned in the groove on the housing as 
intended for.

Adjusting the Drilling Depth (see figure B)

The required drilling depth 

X

 can be set with the depth stop 

13

.

– Press the button for the depth stop adjustment 

12

 and 

insert the depth stop into the auxiliary handle 

14

.

The knurled surface of the depth stop 

13

 must face down-

ward.

– 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.

– Pull out the depth stop until the distance between the tip of 

the drill bit and the tip of the depth stop corresponds with 
the desired drilling depth 

X

.

Selecting Drill Chucks and Tools

For hammer drilling and chiselling, SDS-plus tools are re-
quired that are inserted in the SDS-plus drill chuck.

For drilling without impact in wood, metal, ceramic and 
plastic as well as for screwdriving, tools without SDS-plus are 
used (e. g., drill bits with cylindrical shank). For these tools, a 
keyless chuck or a key type drill chuck are required.

GBH 240 F: The SDS-plus quick change chuck 

2

 can easily be 

replaced against the quick change keyless chuck 

1

 provided.

Changing the Key Type Drill Chuck (GBH 240)

To work with tools without SDS-plus (e. g., drills with cylindri-
cal shank), a suitable drill chuck must be mounted (key type 
drill chuck or keyless chuck, accessories).

Mounting the Key Type Drill Chuck (see figure C)

– Screw the SDS-plus adapter shank 

18

 into a key type drill 

chuck 

17

. Secure the key type drill chuck 

17

 with the 

securing screw 

16

. 

Please observe that the securing 

screw has a left-hand thread.

Inserting the Key Type Drill Chuck (see figure C)

– Clean the shank end of the adapter shank and apply a light 

coat of grease.

– Insert the key type drill chuck with the adapter shank into 

the tool holder with a turning motion until it automatically 
locks.

– Check the locking effect by pulling the key type drill chuck.
