MB 30 E
The rubber buffers (C) on the stand feet ensure secure
standing on a smooth surface.
You can get either a moveable frame or a bench stand for
the MB 30 E.
Connecting the drive unit
Before putting it into operation, check
the ratings of the power supply
network and of the machine for
correspondence.
The drive unit only provides its
maximum output up to a geographical
altitude of 1,000 m above sea-level.
Only connect the plug to the power
supply after the system is ready for
operation and the tool has been
clamped in.
The mains cable should be laid so that no-one can trip over
it.
Make sure, before connecting the machine and after
completing any work, that the rocker switch is set to 0!
Connecting the Flexible Shaft
The flexible shaft is greased and in an operational
condition.
The flexible shaft must meet the size and strength
requirements. The bend radius must not be less than the
minimum bend radius!
MB 20/2 and MB 20/3
The shaft core can be slid out of the protective tube (2) on
the motor connection side of the flexible shaft (1).
Therefore, this side must be connected first.
The retaining spring knob (3) must engage in the hole in
the motor flange on the drive (4) (see Fig. 3).
To release the flexible shaft, press the retaining spring
knob down by hand and remove the flexible shaft
completely.

Sectional view of threaded connection
Screw a suitable screw (M10) onto the shaft
coupling (1), thereby pulling the shaft coupling out
of the hose bush (7).
To secure the shaft coupling, insert the retention
pin (2) into the hole (3) and release the screw
(M10) again.
Block the drive unit motor spindle (4) with the
retention pin through the borehole (5) in the motor
flange (6).
Using the retention pin (2), turn the shaft coupling
(1) up to the stop on the motor spindle.
Remove the retention pin (2) from the shaft
coupling. Remove the retention pin from the
motor spindle (4).
Insert the hose bush (7) into the motor flange (6)
until the retaining spring (8) locks into the hole (9)
on the motor flange (6).
