Commissioning
Before plugging in, check to see that the
rated mains voltage and mains frequency,
as stated on the rating label, match with your
power supply.
Always install an RCD with a maximum trip
current of 30 mA upstream.
BE 650, SBE 650, SBE 650 Impuls:
Make sure the chuck clamps securely:
After drilling for the first time (clockwise), firmly
tighten the safety screw inside the chuck using
a screwdriver. Caution: left-handed thread!
(see Section 7.9)
7.5
Selecting the Direction of Rotation
(BE 650, SBE 650, SBE 650 Impuls)
Do not activate the direction switch (6)
unless the motor has completely stopped.
Select direction of rotation:
R =
Clockwise
L
=
Anticlockwise
Screw the chuck firmly to the spindle and
tighten the safety screw inside the chuck
using a screwdriver. (Caution: left-handed
thread!)
Otherwise it may come loose during
anticlockwise operation (e.g. when
screwdriving).

Open the clamping ring by turning the additional
handle (5) anticlockwise. Push the additional
handle onto the collar of the machine. Insert the
depth stop (4). Securely tighten the additional
handle at the angle required for the application.

Tool Change With
Futuro Plus Keyless Chuck (3)
Quick-action keyless chuck with metal sleeve:
See illustrations on page 2.
Insert the tool. Hold the retaining ring (a) firmly and
turn the collet (b) towards "GRIP, ZU" with the other
hand until the mechanical resistance which can be
felt is overcome.
Caution! The tool is not yet clamped! Keep
turning the sleeve (it must "click" when turning)
until it cannot be turned any further - only now is the
tool securely clamped.
With a soft tool shank, retightening may be required
after a short drilling period.
Open the chuck:
Hold the retaining ring (a) firmly and turn the collet
(b) towards "AUF, RELEASE" with the other hand.
