handle (2) counter-clockwise. Push the additional
handle onto the collar of the machine. Slide the
additional handle far enough forward so that it can
be turned. At the desired angle, pull it back and
tighten firmly.

7.1 Setting direction of rotation,
transport lock (switch-on lock)
Do not activate the rotation selector switch (7)
unless the motor has completely stopped.
See page 2.
R = Clockwise setting
L = Counter-clockwise setting
0 = Central position: transport lock setting
(switch-on lock)
The drill chuck must be firmly screwed onto
the spindle and the safety screw inside the drill
chuck (if applicable / model-specific) must be firmly
tightened with a screwdriver. (Caution, left-handed
thread !) If rotated counterclockwise (e.g. when
screwing) it could otherwise become loose.
7.2 Selecting a gear
Select the desired gear by turning the
thumbwheel (1).
Change speed only when the machine
is in the process of running down
(briefly switch it on and off).
1st gear (low speed, high torque)
e.g. for screwdriving, drilling
2nd gear (high speed) e.g. for drilling
7.3 Preselect speed
Use the setting wheel (5) to preselect the maximum
speed. See page 4 for recommended drilling
speeds.
7.4 Switching on/off, changing speed
Switching on, speed: press the trigger (9).
The speed can be changed by pressing in the
trigger.
The electronic soft start means that the machine
accelerates continuously until the preselected
speed is reached.
Release the trigger to switch off.
Continuous activation: While pressing on the
trigger (9), press in the locking button (8) and
then release the trigger. To switch off, press and
release the trigger (9) again.
In continuous operation, the machine
continues running if it is forced out of your
hands. Therefore, always hold the machine with
10
both hands using the handles provided, stand in
a safe position and concentrate.
7.5 Tool change with Plus (4) chuck
See illustrations A, page 2.
Opening the drill chuck:
Using one hand, hold the retaining ring securely
(depending on equipment, not necessary for
BE 1300 Quick) and, using the other hand, turn the
sleeve in the direction of the arrow -1.
The ratchet sound which can possibly be heard
after opening the drill chuck is functional and is
switched off by a reverse rotation of the sleeve.
BE 751, BE 1100: If the chuck is very securely tight-
ened: Unplug. Hold the chuck using an open-end
spanner at the flats on its head, and turn the sleeve
vigorously in the direction of the arrow -1.
Clamping the tool
- Insert the tool -2- as far as possible.
- Using one hand, hold the retainer ring securely
(depending on equipment; not required for
BE 1300 Quick).
- Turn sleeve in direction -3- until the noticeable
mechanical resistance has been overcome. - Caution! The tool is not yet fully tightened!
Keep turning the sleeve (it must "click" when
turning) until it cannot be turned any further - only
now is the tool safely clamped.
With a soft tool shank, retightening may be required
after a short period of operation.
7.6 Tool change with a geared chuck (3)
See illustrations B on page 2.
Opening the drill chuck: Open the geared chuck
with chuck key -1.
Clamping the tool: Insert tool -2- as far as possible
and, using the chuck key, evenly secure in all 3
bores -3.
