Loosening the Drill Chuck
(see figure )
G
Place the machine on a stable surface (e. g.
workbench). Hold the machine firmly and loosen
the chuck by turning to the left, as when unscrew-
ing a screw ( ). Loosen a tight chuck by giving
the long end of the Allen key 16 a sharp blow.
Tightening the Drill Chuck
(see figure )
H
The drill chuck is mounted in reverse order ( ).
The chuck must be tightened with a torque of
approx. 35 – 40 Nm.
Tips
Speed as well as torque setting depend on the
material and can be determined by practical test-
ing. Always start with the lowest setting.
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 2 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.
