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 hori-
zontally backward, at the same time as the lower fork is pressed
down gently. When the speed selector lever (8) is 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 drawing above.
When all parts have been mounted, the speed must be adjusted.
Adjustment of speed and belt
a) Adjust the distance (8) 12.6", by loosening the 4 bolts (16) and moving the motor back and forth. The tolerance of the
.....
distance (B) can be used in cases where there are problems in adjusting the speed correctly, as the distance (B) is
.....
dependent on the tolerance of the special V-belt.
b) Loosen the lock nut (11) and the adjusting nut (12).
c) Start the mixer and adjust the lowest speed so that the special V-belt (7) is approximately 1/16 to 1/8" (C) from
.....
the pulley edge.
d) Stop the mixer and tighten the adjusting nut (12) loosely and then the lock nut (11)
e) Loosen the lock nut (13) and the adjusting screw (14).
f) Start the mixer and adjust the highest speed so that the special V-belt (7) is approximately 1/16 to 1/8" (C) from
the pulley edge of the motor pulley set (9).
g) Stop the mixer and tighten the adjusting screw (14) loosely and then the lock nut (13).
h) Start the mixer and control the measure (C) on both pulley sets at high and low speed, respectively.
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 above.
Tolerances in the transmission can cause the special V-belt (7) to hit 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 readjusted.
