Inserting The Battery; Electric Brake - Bosch PSB 12 VE-2 Operating Instructions Manual

Changing the Tool
Open the drill chuck 3 by turning until the tool can
be inserted. Insert the tool.
Firmly tighten the sleeve of the keyless chuck 3
by hand until the locking action ("click") is no
longer heard. This automatically locks the chuck.
Rotate the sleeve in the reverse direction to re-
move the tool.
Screwdriving (see figure
Directly clamp the screwdriver bit 7 into the drill
chuck or use the additional universal bit holder 12
when operating with hex shank bits 11.
Starting Operation

Inserting the Battery

Set the rotational direction switch 8 to the centre
position = lock-off and allow the charged bat-
tery 5 to engage into the handle.
Switching On and Off
To start the machine, press the On/Off switch 9
and keep it depressed.
The machine runs with variable
speed between 0 and maximum,
depending on the pressure applied
to the On/Off switch 9. Light pres-
sure results in a low rotational
speed thus allowing smooth, con-
trolled starts. Do not strain the ma-
chine so heavily that it comes to a
standstill.
To switch off the machine, release the On/Off
switch 9.

Electric Brake

When releasing the On/Off switch 9 the speed of
the drill chuck is reduced to a stop, thus prevent-
ing the run-on of the tool.
For screwdriving applications, wait until the screw
is flush with the material and then release the On/
Off switch 9. The screw head does not penetrate
into the material then.

the On/Off switch 9.

Fully Automatic Spindle Locking
(Auto-Lock)
The drill spindle is locked when the On /Off
switch 9 is not pressed.
This makes quick and easy changing of the tool
in the drill chuck possible.
The locked drill chuck enables retightening of
projecting screws by using the switched-off ma-
chine as a screwdriver.

Turn the rotational direction switch through to the
left stop (normal operation: drilling, screwdriving,
etc.).
Left Rotation (
Press the rotational direction switch through to
the right stop (for loosening and unscrewing
screws and nuts).
