Assembly

f Before any work on the machine (e. g.,

maintenance, tool change, etc.) as well as

during transport and storage, set the rota-

tional direction switch to the centre posi-

tion. Unintentional actuation of the On/Off

switch can lead to injuries.

Battery Charging

A battery that is new or has not been used for a

longer period does not develop its full capacity

until after approx. 5 charging/discharging cy-

cles.

To remove the battery 11 press the unlocking

buttons 10 and pull out the battery downwards.

Do not exert any force. (see figure A)

The battery is equipped with a NTC temperature

control which allows charging only within a tem-

perature range of between 0 °C and 45 °C. A

long battery service life is achieved in this man-

ner.

A significantly reduced working period after

charging indicates that the battery is used and

must be replaced.

Observe the notes for disposal.

Auxiliary Hooks for Locking of Battery

(see figure A)

Due to wear of the battery locking hooks or in-

complete inserting of the battery 11 into the

battery port, the battery can engage in the aux-

iliary hooks 14. Should the auxiliary hooks 14 on

the power tool or on the battery be damaged,

then neither the power tool nor the battery may

continue to be used, but are to be sent in to an

authorised after-sales service centre for Bosch

power tools.

Auxiliary Handle

f Operate your machine only with the auxilia-

ry handle 12.

The auxiliary handle 12 can be set to any posi-

tion for a secure and low-fatigue working pos-

ture.

Turn the bottom part of the auxiliary handle 12

in counterclockwise direction and swivel the

auxiliary handle 12 to the desired position. Then

retighten the bottom part of the auxiliary handle

12 by turning in clockwise direction.

The clamping band 5 of the auxiliary handle

must be seated in the corresponding groove.

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

6 and insert the depth stop into the auxiliary

handle 12.

Insert the SDS-plus drilling tool to the stop into

the SDS-plus tool holder 1. Otherwise, the mov-

ability of the SDS-plus drilling tool can lead to

incorrect adjustment of the drilling depth.

Pull out the depth stop until the distance be-

tween the tip of the drill bit and the tip of the

depth stop correspond with the desired drilling

depth X.

The knurled surface of the depth stop 13 must

face upward.

Selecting the Tool Holder

For hammer drilling, SDS-plus drilling tools that

can be inserted into the SDS-plus tool holder 1

are required.

For drilling without impact in wood, metal, ce-

ramic and plastic, use non-SDS-plus drilling

tools (e. g. drill bits with cylindrical shank). A

keyless or a key type drill chuck is required for

such drilling tools.

Note: Do not use drilling tools without SDS-plus

for hammer drilling! Drilling tools without SDS-

plus as well as the tool holder are damaged

when used for hammer drilling.

GBH 24 VF: The SDS-plus tool holder 1 can eas-

ily be exchanged against the keyless replace-

ment chuck 18 provided.
