Assembly
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 cycles.
To remove the battery 6 press the unlocking but-
tons 7 and pull out the battery downwards. Do
not exert any force.
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 manner.
A significantly reduced working period after
charging indicates that the battery is used and
must be replaced.
Observe the notes for disposal.
Changing the Tool (see figure A)
Before any work on the machine (e. g., main-
tenance, tool change, etc.) as well as during
transport and storage, set the rotational di-
rection switch to the centre position. Unin-
tentional actuation of the On/Off switch can
lead to injuries.
Hold the rear sleeve 3 of the keyless chuck 1 tight
and turn the front sleeve 2 in rotation direction
, until the tool can be inserted. Insert the tool.
Hold the rear sleeve 3 of the keyless chuck 1 tight
and firmly turn the front sleeve 2 in rotation di-
rection by hand.
The locking is released again to remove the tool
when the front sleeve 2 is turned in the opposite
direction.
Replacing the Drill Chuck
Before any work on the machine (e. g., main-
tenance, tool change, etc.) as well as during
transport and storage, set the rotational di-
rection switch to the centre position. Unin-
tentional actuation of the On/Off switch can
lead to injuries.
Bosch Power Tools
Removing the Securing Screw (see figure B)
The keyless chuck 1 is secured with a securing
screw 12 against unintentional loosening from
the drill spindle. Completely open the keyless
chuck 1 and unscrew the securing screw 12 in ro-
tation direction . Please note that the securing
screw has a left-hand thread.
Removing the Drill Chuck (see figure C)
Clamp the short end of an Allen key 13 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 Allen key 13 in
rotation direction . Loosen a tight-seated key-
less chuck by giving the long end of the Allen key
13 a light blow. Remove the Allen key from the
keyless chuck and completely unscrew the key-
less chuck.
Mounting the Drill Chuck (see figure D)
The keyless chuck is mounted in reverse order.
Note: After mounting the keyless chuck, screw
the securing screw 12 in again.
The drill chuck must be tightened with a
tightening torque of approx. 35–40 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. Touch-
ing or breathing-in the dusts can cause aller-
gic reactions and/or lead to respiratory infec-
tions of the user or bystanders.
Certain dusts, such as oak or beech dust, are
considered as carcinogenic, especially in con-
nection with wood-treatment additives (chro-
mate, wood preservative). Materials contain-
ing asbestos may only be worked by
specialists.
– Use dust extraction whenever possible.
– Provide for good ventilation of the working
place.
– It is recommended to wear a P2 filter-class
respirator.
Observe the relevant regulations in your coun-
try for the materials to be worked.
