Replacing the Drill Chuck
Before any work on the machine itself, pull the
mains plug.
Removing the Drill Chuck (see figure I)
Disassemble the auxiliary handle and set the gear
selector 11 to the centre position between the 1st and
2nd gear.
Insert a steel pin with a diameter of Ø 4 mm and
approx. 50 mm of length into the drill hole on the spin-
dle neck in order to lock the drill spindle.
Clamp the short end of an Allen key 27 into the keyless
chuck 1.
Place the machine on a stable surface (e.g. a work-
bench). Hold the machine firmly and loosen the keyless
chuck 1 by turning the Allen key 27 in anticlockwise
direction. Loosen a tight-seated keyless chuck by giv-
ing the long end of the Allen key 27 a light blow.
Remove the Allen key from the keyless chuck and com-
pletely unscrew the keyless chuck.
Mounting the Drill Chuck (see figure J)
The keyless chuck is mounted in reverse order.
Remove the steel pin from the drill hole on the
spindle neck after mounting is completed.
The drill chuck must be tightened with a
tightening torque of approx. 50–55 Nm.
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.
Stand by Indicator (PSB 1000-2 RCA)
The stand by indicator 5 lights up when the mains plug
is plugged in and mains voltage is available. When the
machine cannot be started even though the stand by
indicator is lit, it must be taken to an authorized after-
sales service agent for Bosch power tools.
Reversing the Rotational Direction (see figure K)
The rotational direction switch 10 is used to reverse the
rotational direction of the machine. However, this is not
possible with the On/Off switch 9 actuated.
Right rotation: Press the rotational direction switch
10 through to the right stop (for drilling and driving
screws).
PSB 1000-2 RCA: The indicator for right-hand rotation
3 lights up.

PSB 700-2 RE/PSB 800-2 RA: The indicator for right-
hand rotation 29 indicates the selected rotational direc-
tion.
Left rotation: Press the rotational direction switch 10
through to the left stop (for loosening and unscrewing
screws and nuts).
PSB 1000-2 RCA: The indicator for left-hand rotation
4 lights up.
PSB 700-2 RE/PSB 800-2 RA: The indicator for left-
hand rotation 30 indicates the selected rotational direc-
tion.
Setting the Operating Mode
Drilling and Screwdriving
Set the selector switch 2 to the "Drilling"
symbol.
Impact Drilling
Set the selector switch 2 to the "Impact drill-
ing" 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 9 and
keep it depressed.
To lock the pressed On/Off switch 9, press the lock-
on button 8.
To switch off the machine, release the On/Off switch
9 or when it is locked with the lock-on button 8, briefly
press the On/Off switch 9 and then release it.
Gear Selection, Mechanical
Actuate the gear selector 11 only when the machine is
at a standstill.
Two speed ranges can be preselected with the gear
selector 11.
1st gear:
Low speed range; for working with large
drilling diameter or for driving screws.
2nd gear:
High speed range; for working with small
drilling diameter.
PSB 1000-2 RCA: Position "S":
Low speed range; for working with high
torque, e.g. when working with core bits
or for driving screws.
If the gear selector 11 cannot be fully engaged, lightly
rotate the drive spindle with the drill bit by twisting the
drill chuck.
