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
f
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.
