Replacing the Drill Chuck
(0 603 387 5.. – see figures
Clamp the short end of an Allen key in the chuck.
Place the machine on a firm surface (e. g. work-
bench). Lock the drill spindle with the spindle
locking button 2, hold the machine firmly and
loosen the chuck by turning to the left in the same
way as for a screw ( ). Loosen a tightly sitting
chuck by giving the long shaft of the Allen key 16
a sharp knock.
The drill chuck is mounted in reverse order ( ).
The chuck must be tightened with a
torque of approx. 25 – 30 Nm.

For machines without a drill spindle locking facil-
ity, the chuck must be changed by an authorised
after-sales service shop for Bosch power tools.
The chuck must be tightened with a
torque of approx. 30 – 35 Nm.
Tips
The required speed is dependent on the material
and can be determined by practical testing.
After longer periods of working at low speed, al-
low the machine to cool down by running for ap-
prox. 3 minutes at maximum speed with no load.
For drilling in tiles, set the selector switch 3 to the
symbol "Drilling and Screwdriving". Do not switch
over to the symbol "Impact Drilling" or work with
impact until after drilling through the tile.
Carbide tipped drill bits are required for jobs
when working in concrete, masonry and brick
wall.
Maintenance and Cleaning
Before any work on the machine itself, pull
the mains plug.
For safe and proper working, always keep
the machine and the ventilation slots clean.
If the machine should fail despite the care taken
in manufacturing and testing procedures, repair
should be carried out by an after-sales service
centre for Bosch power tools.
In all correspondence and spare parts orders,
please always include the 10-digit order number
given on the nameplate of the machine.
