ABOUT YOUR KITCHEN MACHINE
Congratulations on having selected one of
the Bosch Compact Series Kitchen
Machines. A series of kitchen machines that
we and—thankfully—cooking professionals
the world over, feel are the best compact
household-type kitchen machines available.
As you read through these instructions,
please pay particular attention to the
IMPORTANT SAFEGUARDS. Specific
safeguards for the attachments, as well as
warnings and cautions, are provided in each
section describing the operation of that
particular attachment.
Bosch Compact Series Kitchen Machine
The Bosch Compact Series Kitchen
Machine is available in 4 models:
• The MUM 4405 UC
comprised of the 400-watt power unit
with integral cord storage, four-quart
capacity mixing bowl, with anti-splash

whisks and dough hook and high speed
drive cover.
• The MUM 4420 UC
comprised of the 400-watt power unit
with integral cord storage, four-quart
capacity mixing bowl with anti-splash
cover (MUZ4KR3), beating, stirring

Unpacking
Carefully remove the power unit from its
packaging and place it on the counter so it
is ready to use. As you remove the
accessories from the carton, check them
against Figure 1 to ensure that all the
standard parts are present.
Electrical Specifications
Check to make sure that the voltage on
which your kitchen machine is to operate
is the same as specified on the rating plate.
Standard North American models have an
electrical power rating of 400- or 450-watt
maximum power rating with the accessory
attachment that draws the most power
(some accessory attachments may draw
less power).
Before Using for the First Time
Before using any of the attachments for the
first time it is recommended they be washed,
rinsed well and dried. Of the attachments
supplied, with the systems in this manual,
all parts, except the blender’s blade/base
assembly, are dishwasher safe:
• The MUM 4620 UC
comprised of the 450-watt power unit
with integral, internal, cord storage, fourquart capacity mixing bowl, with antisplash cover (MUZ4KR3), beating,
stirring whisks and dough hook, blender
(MUZ4MX2), high-speed drive cover and
accessory holder.
> The blender’s blade/base assembly
should be washed under running water
and dried.
Note: It is recommended that the blender’s
blade/base assembly never be left to
stand in water or soap solution to prevent
the bearing lubricant from being washed out.

Getting to Know Your Bosch Kitchen
Machine
The Bosch Compact Series Kitchen
Machines are comprised of various
attachments, depending on the system
purchased (see above). In addition to the
attachments listed on the previous pages
that are available with the standard systems,
Bosch offers many special accessories.
Special Accessories
To allow you to get the most service from
your Bosch Compact Series Kitchen
Machine, Bosch engineers have designed
a line of special accessories to expand the
usefulness of your machine. In addition to
the attachments that come with the various
Compact Series Kitchen Machines, there
are optional accessories that can be ordered
separately. These accessories include a
food and meat grinder, grain mills, citrus
juicer and ice cream maker, plus additional
attachments that can be used with the meat
grinder: fancy cookie attachment, fruit pulper
and grater attachment. See SPECIAL
ACCESSORIES at the back of this
booklet, page 23. Or, to view all currently
available accessories, visit our Web site at
www.boschsmallappliances.com
Work on expanding the usefulness of the
Bosch Compact Series Kitchen Machine
is a continuing process. If there is some
type of accessory in which you are
interested in that you cannot find at the back
of the book or on our Web site, please either

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
convenient cord storage located on the back
of the power unit, where the cord may be
wound around the holder, see 2d.
The MUM 4620 and the MUM 4635 have
internal cord storage. To store the cord or
reduce the length of the cord with these
two units, simply pull on the cord and let
the cord be retracted into the base of the
machine, see figure 2.
Four rubber feet
Four rubber feet will provide the stability,
while also serving to isolate the power unit
from the hard surface to minimize noise and
vibration.
Figure 2.

Getting Started
The operation of your Bosch Compact
Series Kitchen Machine is summarized
below.
Specific instructions for using each of the
attachments, provided with the kitchen
machine systems covered by this manual,
follow the summarized instructions. Please
read the specific instructions thoroughly
before using that attachment, paying
particular attention to the IMPORTANT
SAFEGUARDS and WARNINGS provided.
1. Place power unit on suitable work
surface.
Before using the machine with any of
the attachments, the power unit should
be placed on a suitable work surface.
The surface should be sturdy, smooth
and clean; make sure that there is no
flour or oil on the surface. A clean
smooth surface will provide the best
footing and will limit slipping and/or
“walking.”
3. Remove drive cover.
Remove drive cover from drive to be
used, if necessary, see figure 2c.
4. Select attachment to be used.
Select attachment you wish to use.
Reposition the ergonomic multifunction
arm, if necessary (see figure 4a & 4b),
and place attachment on power unit.
The Bosch Compact Series Kitchen
Machine uses its attachments in 6
modes. The various modes used (the
drive and position of the arm) are
shown in table 1.
2. Plug power unit into power supply.
Pull the electrical cord or unwind the
electrical cord to appropriate length.
Make sure power unit is turned to Off
“O/Off” and plug it into a convenient
nearby receptacle. Turn rotary knob
to park “P” position to make sure the
drives are in proper position to rotate
arm and/or install attachment. If motor
does not reposition drives when turned
to “P” position, the drives were already
in position for arm to be rotated.
WARNING
1. Do not twist or attempt to push in the
electrical cord. If the cord becomes
jammed, pull out the cord to its full
length and then allow it to slowly
retract.
2. If the power should be interrupted, the
power unit will remain on and will restart
when power is restored.
