Adjusting of bowl clamping and centering:
In the rear part of the bowl arms (J) a shaft with an eccentric stud (K) has been mounted, on which the ball bearing is
mounted. By turning the eccentric stud, the bowl arms can be opened and closed so that the clamping and the center-
ing of the bowl can be adjusted. It has to be observed that the shaft is mounted in the bowl arm with a thread so that
when the eccentric stud is turned, the whole shaft is turned out and in into the bowl arms. When exchanging the whole
shaft, the right starting point for the adjustment must be found first. The ball bearing (L) must be in the middle of the
guide plate (M) so that the width of the entire ball bearing is fitting tightly against the guide plate, and at the same time
it has to be observed that the eccentric stud cannot hit the back plate when the adjustment has been finished.
In order to counteract that the eccentric shaft turns loose by itself when the mixer is working, the eccentric shaft must
be self-tightening. In order to obtain this effect, the below drawings must be followed, on which the adjusting area for
the left and the right bowl arm, resp. is shown.
First find the bowl centering, e.g. by mounting bowl and beater in the mixer, and turn the beater round with your hand,
and measure the distance from the beater to the edge of the bowl.
• When adjusting the clamping and centering of the bowl,
the bowl arms must be raised into working position. When
exchanging the shaft with eccentric stud (K) the bowl arms
must be lowered.
• First open the lock plate (N).
• Loosen the shaft counter nut (P), use span 46.
• Screw an M8 bolt with counter nut (R) into both the ec-
centric studs (K), and tighten the counter nuts. If the shaft
with the eccentric stud has stuck in the bowl arm, it can be
loosened with a key with the span 36.
• By turning the eccentric studs the clamping and the center-
ing of the bowl can be adjusted.
• Remember to use the right adjusting area for right and left
bowl arm. The drawings show the adjusting area for
• When the adjustment is correct, tighten the shaft counter
nuts (P). Hold the bolt (R) while the shaft counter nut is
tightened.
• Knock the lock plate (N) in position.
• Remove bolt and counter nut
