Bosch PSB 12 ve-2 Bedienungsanleitung Seite 12

Setting the Torque
Carry out a practical test to determine with which
of the 5 settings of the torque setting ring 2 the
screws are driven flush into the material.
Low setting, e. g., small screws, soft
1
materials.
High setting, e. g., large screws, hard
5
materials.
With the correct setting, the clutch disengages as
soon as the screw is driven flush into the material
or the set torque is reached. Select a higher set-
ting when driving out screws, or set to the "Drill-
ing" symbol.
Drilling and Impact Drilling
Drilling
Set the torque setting ring 2 to the "Drill-
ing" symbol.
Impact Drilling

"Hammer Drilling" symbol.
Replacing the Drill Chuck
Before any work on the machine itself, re-
move the battery.
The locking screw 14 secures the drill chuck
against loosening from the drill spindle. Fully
open the drill chuck and completely unscrew the
locking screw 14 by turning in clockwise direction
(see figure E ).
Loosening the Drill Chuck

C
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 13 a sharp blow.

Tips
Use only screwdriver bits that fit properly in the
head of the screw.
When driving in larger and/or longer screws in
hard material, it is advisable to drill a pilot hole
first.
For drilling in metal, use only perfectly sharp-
ened HSS drills. The appropriate quality is
guaranteed by the Bosch accessories pro-
gram.
Maintenance and Cleaning
Before any work on the machine itself, re-
move the battery.
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.
Environmental Protection
Recycle raw materials instead of disposing as
waste
The machine, accessories and packaging should
be sorted for environmental-friendly recycling.
These instructions are printed on recycled paper
manufactured without chlorine.
The plastic components are labelled for catego-
rized recycling.
