Certain dusts, such as oak or beech dust, are
considered as carcinogenic, especially in con-
nection with wood-treatment additives (chro-
mate, wood preservative). Materials contain-
ing asbestos may only be worked by
specialists.
– Use dust extraction whenever possible.
– Provide for good ventilation of the working
place.
– It is recommended to wear a P2 filter-class
respirator.
Observe the relevant regulations in your coun-
try for the materials to be worked.
Operation

Starting Operation

Observe correct mains voltage! The voltage
of the power source must agree with the
voltage specified on the nameplate of the
machine. Power tools marked with 230 V can
also be operated with 220 V.
Reversing the Rotational Direction
(see figures E–F)
The rotational direction switch 7 is used to re-
verse the rotational direction of the machine.
However, this is not possible with the On/Off
switch 6 actuated.
Right Rotation: For drilling and driving in screws,
push the rotational direction switch 7 left to the
stop.
Left Rotation: For loosening and unscrewing
screws and nuts, press the rotational direction
switch 7 through to the right stop.
Setting the Operating Mode
Drilling and Screwdriving
Set the selector switch 2 to the "Drill-
ing" symbol.
Impact Drilling
Set the selector switch 2 to the "Impact
drilling" symbol.
The selector switch 2 engages noticeably and
can also be actuated with the machine running.

Switching On and Off
To start the machine, press the On/Off switch 6
and keep it depressed.
To lock the pressed On/Off switch 6, press the
lock-on button 5.
To switch off the machine, release the On/Off
switch 6 or when it is locked with the lock-on but-
ton 5, briefly press the On/Off switch 6 and then
release it.
Adjusting the Speed/Impact Frequency
The speed/impact rate of the switched on power
tool can be variably adjusted, depending on how
far the On/Off switch 6 is pressed.
Light pressure on the On/Off switch 6 results in
low speed/impact rate. Further pressure on the
switch increases the speed/impact rate.
Preselecting the Speed/Impact Frequency
(see figure G) (PSB 700 RE/PSB 700 RES)
With the thumbwheel for speed preselection 15,
the required speed/impact frequency can be
preselected even during operation.
The required speed/impact frequency depends
on the material and the working conditions, and
can be determined through practical testing.
Electronic Torque Limitation/Speed Preselec-
tion (Torque Control) (PSB 1000 RPE)
Drilling with speed preselection: Set
the selector switch 4 to the "Drilling"
symbol. The required speed can be
selected with the thumbwheel 3; it
can also be adjusted during opera-
tion.
Screwdriving with torque limitation:
Set the selector switch 4 to the
"Screwdriving" symbol. The effective
torque at the drill spindle can be var-
iable adjusted with the thumbwheel
3 during operation:
I=low torque, III=high torque.
The maximum speed is automatically adapted to
the adjusted torque.
