Power Unit Features
Motor
The MUM 4405 and MUM 4420 have a 400watt motor while the MUM 4620 and MUM
4635 have a 450-watt motor, the most
powerful motor offered with any compact
household kitchen machine.
All MUM Compact Series power units have
the following features, refer to figure 2:
Electronic speed control
Six-position rotary switch is located at the
side of the multifunction arm of the power
unit: 4 speeds plus a locking park position
“P” and a stop position “O/Off,” see figure
2a.
Three accessory drives
Three drives:
• A high-speed drive used for blender
and other attachments requiring highshaft speed
• A mid-speed drive used for continuous
shredder attachment and other
attachments requiring mid-range shaft
speeds
and
• A high torque drive used for whisks,
dough hook and meat grinder
attachment and other attachments
requiring more torque.
Each of these drives is controlled by the 4speed electronic control providing 12
distinct shaft speeds optimizing the motor
speed for different loads encountered by
different attachments.
Ergonomic multifunction arm
Four locking positions place attachments
in most ergonomic position for their use.
Park position “P”
Six-position rotary switch, located at side
of the multifunction arm of the power unit,
has “P” position used to “park” the drive unit.
The drives must be placed in the park
position prior to changing position of
ergonomic multifunction arm. If drives are
6
not in proper position for rotating the arm
turning the rotary switch to the “P” position
will cause motor to reposition drives. If motor
does not reposition drives when turned to
the “P” position, the drives are already in
position for arm to be rotated.
Motor drive covers
Two covers are provided to cover high -speed
and mid-speed drive when they are not in
use, see figure 2c.
Convenient cord storage
The MUM 4405 and MUM 4420 have

2. The mixture should be removed and the
contents at the bottom of the jar
loosened.
Removing Contents
Before beginning to remove the contents
from the blender, make sure that the power
unit has been turned to off position “O/Off.”
Remove the blender from the power unit by
turning the blender clockwise while lifting.
With the blender removed from the power
unit, the contents of the blender may now
be poured into a suitable container or bowl,
as desired. Replace the cover on the highspeed drive.
Care and Cleaning of Blender
All components of the blender, except the
blade/base assembly, are dishwasher safe.
It is recommended that the blade/base
assembly be cleaned only under flowing
water rather than in the dishwasher. Soap
and detergent will tend to wash out the
bearing lubricant of the blade/base
assembly. Do not use scouring cleaners on
any of the blender parts.
The power unit of the kitchen machine
should be cleaned with a clean, damp cloth
only. Never use coarse or caustic cleaning
products to clean this appliance. Never
immerse the power unit in water.

shredder attachment consists of, figure 9:
Figure 9.
Use of Slicer/Shredder
Before beginning to use this or any other
attachment, make sure that the power unit
is on a smooth, clean, suitable work
surface and switched to Off position,
“O/Off,” and that you have removed the
motor drive cover.
1. Before using the continuous shredder
for the first time, it is recommended that
the cover closure/pusher, cover, discs,
disc holder/slinger and housing be
washed. All components of the
continuous shredder are dishwasher
safe. After washing, rinse well and
dry before using.
WARNING
The blades on the discs are very sharp.
Handle with care.
2. The continuous shredder is used in
mode 2, see table 1. To place the
continuous shredded on the power unit,
the arm must be rotated to the
horizontal position. Depress the release
button, see 4a, and move the arm as
necessary so that the arm is horizontal.
If you have not already done so, remove
the motor drive cover from the midspeed drive, as shown in figure 10.
16
Figure 10.
Assemble the continuous shredder in the
order as shown in figure 9:
1. Insert the disc holder/slinger into
the housing.
2. Select disc to be used and,
making sure that the side desired
is facing upward, place it on disc
holder.
3. Place cover on housing and turn
counterclockwise until cover snaps
into place and arrows are aligned,
see figure 11.
4. The continuous shredder is now
assembled.
5. Place bowl on the power unit.
Depress the release button and
raise arm so that the bowl can be
placed in position, and then lower
the arm to horizontal position.
6. Place continuous shredder on the
mid-speed drive of the power unit,
with the arm in the horizontal
position and turn counterclockwise
until it locks into position.
Placing Slicer/Shredder into Operation
Make sure the power unit is on a smooth,
clean, suitable work surface and switched
to the Off position, “O/Off.” Pull the electrical
cord or unwind the electrical cord to the
necessary length and plug into a convenient
outlet. The continuous shredder is now
ready for use.
Figure 11.
Place items to be sliced, shredded or
grated in feeding funnel and be sure to use
the pusher to feed items into the discs when
in operation.
Learning how to feed food properly into the
feed funnel is the most important factor for
proper slicing and grating:
17
1. For long slices or long shreds, place
food into the feeding funnel lengthwise.
2. For short or circular slices, place food
in the feeding tube on end. For
example, If you wish to have circular
slices of zucchini or carrots:
• cut to length not to extend above the
top of the feeding tube.
• place the cut zucchini or carrots in
the feeding tube on end until the
feeding tube is packed.
To slice a single narrow item, a carrot for
example:
• place the carrot in the feeding funnel
opposite the cutting edge of the disc.
The wall of the feeding funnel will then serve
to hold the piece vertical.
When using the continuous shredder, be
sure to watch the level in the bowl and stop
the slicing, shredding or grating before the
level of the material being sliced, shredded
or grated blocks the discharge tube.
Slicing and shredding tips:
1. Shopping for fruits and vegetables that
will fit into the feeding funnel will simplify
food preparation.
4. Do not overcook potatoes that are to
be sliced. Also it is recommended that
you let them cool first. Potatoes must
be cool and firm to obtain the regular
slices.
If the slicer/shredder does not start (even
after trying the highest speed) the disc has
become blocked by the contents. The
power unit should be:
1. Switched to Off position, “O/Off,” and
unplugged.
2. The continuous shredder should be
removed from the power unit, the cover
removed and the items causing the
blockage removed.
Removing Contents
Before beginning to remove the contents
from the bowl, make sure that the power
unit has been turned to the Off position,
“O/Off.” The continuous shredder may be
removed from the power unit by turning the
shredder clockwise while lifting. With the
continuous shredder removed from the
power unit, depress the release button and
move the arm upward until the bowl can be
removed. The contents of the bowl may now
be poured into a suitable container or bowl,
as desired.
2. Foods that are to be used together may
be sliced together. This can be used to
your advantage. For example, green
onions and celery are often used
together, but feeding the green onions
into the feeding funnel alone is difficult.
Try slicing the green onions at the same
time as the celery by interspersing
them in the feeding funnel with the
celery.
3. Use the slicing disc to shred lettuce.
Care and Cleaning
of Continuous Shredder
All components of the continuous shredder
are dishwasher safe. Do not use scouring
cleaners on any of the continuous shredder
parts.
The power unit of the kitchen machine
should be cleaned with a clean, damp cloth
only. Never use coarse or caustic cleaning
products to clean this appliance. Never
immerse the power unit in water.
