Adjustment of bowl fixing:
The bowl arms must be raised to normal working posi-
tion. Loosen the counter nuts (1) (fig. 6) and remove the
cotter pins (2) . Turn the bolts (3) until correct fixing of the
bowl is achieved. By turning the bolts out of the extension
tube the fixing is increased. Start by turning one of the
bolts half a revolution.
The adjusting diameter shall be measured inside be-
tween the bowl arms:

Adjustment of bowl centering:
Loosen the counter nuts
(1) (fig. 6)
and remove the cotter
pins
(2)
. Turn the bolts
(3)
until the bowl is in the centre of
the mixer. In order not to alter the fixing of the bowl, one of
the bolts must be turned
out
of the extension tube and the
other
into
the extension tube. Use the flat beater to check
that the bowl is correctly centred and turn the planetary
head with your hand before the voltage is connected.

Adjustment of bowl height:
The upper and lower position of the bowl is determined
by micro switch (1) and (2), (fig. 6a).
The two mechanical stops consisting of the bolts (3) and
(4) are adjusted so that they will be hit approx. 1 mm after
the micro switch, in case the micro switch should fail. The
upper position of the bowl arms is adjusted by bending the
spring arm on the micro switch (1) forwards or backwards ,
It is of utmost importance that the stop screw (3) is re-
adjusted afterwards. In the same way the lower position
is adjusted by altering the micro switch (2). It is important
that the micro switch is not altered so much that the bowl
arms can not hit it.
Thereafter the mechanical stop (4) is adjusted.
