Bosch PSB 600 RE Bedienungsanleitung Seite 12

Two-step switch (PSB 650-2)
Two speed ranges can be preselected with the
On/Off switch 5. The machine switches from the
first to the second speed step after a noticeable
pressure point has been exceeded:
Rotational speed step I:
Rotational speed step II:
The On/Off switch can be locked in either of the
speed steps with the lock-on button 4.
Reversing the Rotational Direction
(PSB 600 RE/PSB 640 RE/
PSB 650 RE/PSB 700 RE)
Operate the rotational direction switch 7 only
at a standstill.
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 5 actuated.

Press the rotational direction switch through to
the left stop (for drilling, impact drilling, driving
screws, etc.).
Left Rotation (see figure
Press the rotational direction switch through to
the right stop (for loosening and unscrewing
screws and nuts).

Replacing the Drill Chuck
Clamp the short end of an Allen key in the chuck.
Loosening the Drill Chuck
(see figure )
E
Place the machine on a firm surface (e. g. work-
bench). Lock the drill spindle with the spindle
locking button 2, hold the machine firmly and
loosen the chuck by turning to the left in the same
way as for a screw ( ). Loosen a tightly sitting
chuck by giving the long shaft of the Allen key 14
a sharp knock.
Tightening the Drill Chuck
(see figure )
F
The drill chuck is mounted in reverse order ( ).
The chuck must be tightened with a torque of
approx. 30 – 35 Nm.
Vibration Damping
(see figure
G
(PSB 650 RE/PSB 700 RE)
The vibration damper 15 reduces occuring vibra-
tions.
For changing, insert the screwdriver 16 into the
special groove designed for this purpose on the
lower part of the gripping surface. Carefully lever
off.
Tips
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 for ap-
prox. 3 minutes at maximum speed with no load.
For drilling in tiles, set the selector switch 3 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.
