The MUM 4750 UC has a 450Ćwatt motor.
The MUM 4750 UC power units has the following feaĆ
tures:
SixĆposition rotary switch is located at the side of the
multifunction arm of the power unit:
4 speeds plus a momentary pulse position M" and
a stop position O/Off", see figure 2a.
- A highĆspeed drive used for blender and other atĆ
tachments requiring highĆshaft speed
- A midĆspeed drive used for continuous shredder
attachment and other attachments requiring midĆ
range shaft speeds
and
- A high torque drive used for whisks, dough hook
and meat grinder attachment and other attachĆ
ments requiring more torque.
Each of these drives is controlled by the 4Ćspeed elecĆ
tronic control providing 12 distinct shaft speeds optiĆ
mizing the motor speed for different loads encounĆ
tered by different attachments.
Four locking positions place attachments in the most
ergonomic position for their use, see figure 2b.
"M" is a momentary pulse function that provides full
speed and power for the time it is held in this position.
The power unit has indicator lights which indicate
standby (a) and switching positions (b) while the drive
is running.
The standby indicator lights up red when the unit is
supplied with power. If the rotary switch is rotated to
one of the speed settings, the corresponding indicator
light illuminates.
The indicator lights flash following a power interruption
or if the unit is overloaded. See TROUBLESHOOTING

Two covers are provided to cover highĆspeed and
