Mounting of the planetary head should be done in reverse order.

When the lower fork (15) and the spring (34) are mounted, the speed

selector lever (8) is turned counter clockwise, so that it points horizontally

backwards, at the same time as the lower fork is pressed gently down.

When the speed selector lever (8) is now turned clockwise, it will catch

the toothed rack (35) and pull down the lower fork. Screw on the

nuts (11) and (12).

Be aware that the pin (39) on the lower part (32) of the pulley set is to be

placed as shown in the above mentioned drawing.

When everything has been mounted, the speed has to be adjusted.

Drawing A.

See drawing A.

ADJUSTMENT OF SPEED:

a) Control and if necessary adjust the distance (B) = 318 +/- 3 mm, by loosening the 4 bolts (16) and move the motor

backwards and forwards. The tolerance of the distance (B) can be used in cases when there are problems in ad-

justing the speed correctly, as the distance (B) is dependent on the tolerance of the special V-belt.

b) The counter nut (11) and the adjusting nut (12) are loosened.

c) Start the mixer and adjust the lowest speed so that the special V-belt (7) is approx. 1-2 mm (C) from the pulley

edge.

d) Stop the mixer and tighten loosely the adjusting nut (12), and thereafter the counter nut (11).

e) The counter nut (13) and the adjusting screw (14) are loosened.

f) Start the mixer and adjust the highest speed so that the special V-belt (7) is approx. 1-2 mm (C) from the pulley

edge of the motor pulley set (9).

g) Stop the mixer and tighten loosely the adjusting screw (14), and thereafter the counter nut (13).

h) Start the mixer and control the measure (C) on both pulley sets at high and low speed, resp.

i) Be aware that the pin (39) on the lower part (32) of the pulley set is to be placed as shown on the drawing opposite.

Tolerances in the transmission can cause that the special V-belt (7) is hitting the pins of

the pulley sets when the speed has been adjusted. In these cases the distance (B) is to

be reduced and the speed to be adjusted again.
