Electronic Torque Limitation/
Speed Preselection
(Power Control – PSB 750-2 RPE)
Set the selector switch 2 to the "Drilling and
Screwing" symbol.
Drilling with speed preselection
Set the selector switch 4 to the "Drill-
ing" symbol. The required speed can
be pre-selected with the thumb-
wheel 3 (also during running).
Screwdriving with torque limitation
Set the selector switch 4 to the
"Screwdriving" symbol. The effective
torque at the drill spindle can be var-
iably adjusted (0.5–5.5 Nm) with the
thumbwheel 3:
I = low torque
III = high torque
(e. g. screw 6 x 40)
The maximum speed is automatically adapted to
the adjusted torque.
If the pre-selected torque is reached during
screwdriving, the machine switches off and
stops. If the load on the machine is then removed
with the On/Off switch 6 still pressed, the contin-
ued run is at very low speed for safety reasons.
Briefly releasing the On/Off switch 6 automati-
cally restores the previous operating condition,
so that the next screw will be driven in with the
same torque.
Screwdriving without torque limitation
When the dial control 3 is turned all
the way to the right, the torque limita-
tion is not effective. This setting is re-
quired, e. g. when the power in posi-
tion III is not sufficient (max. torque
7.5 Nm).
Caution: The machine does not
switch off.

Replacing the Drill Chuck
The chuck may be changed only in the first
gear.
Clamp the short end of an Allen key in the chuck.
Loosening the Drill Chuck
(see figure
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 18 a sharp blow.
Tightening the Drill Chuck
(see figure
The drill chuck is mounted in reverse order ( ).
The chuck must be tightened with a
torque of approx. 30–35 Nm.
Vibration Damping
(PSB 750-2 RE/PSB 750-2 RPE –
see figure
The vibration damper 19 reduces occuring vibra-
tions.
For changing, insert the screwdriver 20 into the
special groove designed for this purpose on the
lower part of the gripping surface. Carefully lever
off.
Tips
Apply the power tool to the screw /nut only
when it is switched off.
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 it 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.
