depressing the “-” button after first
selecting the timer function. The
time could then be adjusted down
from 30 minutes by depressing the
“-” button.
Using the Rotary Switch
Once the attachment is in place, the
speed of its moving components can
be controlled through the use of the
rotary switch at the front of the power
unit. See figure 2a. The rotary switch
has six positions:
a. “M,” a momentary “pulse” position
that provides full speed and power
for the time it is held in position.
b. “O/Off,” the Off position.
c. Four speeds labeled 1, 2, 3 and 4.
Speed 1 is the lowest speed. The
speed increases with each
succeeding step up to the highest
speed, speed 4. The selected
speed is also indicated by the bar
at the top of the digital display, see
figure 2c, 1. The bar is broken into
four separate segments. For Speed
1 a single segment is illuminated,
for Speed 2 two segments are
illuminated. This continues until
Speed 4 when all four segments at
the top of the display are
illuminated.
Timer with Rotary Switch
If the timer function had been turned
on prior to switching the power unit on
and setting the speed with the rotary
switch, the power unit will run for the
time selected and then turn itself off.
The digital display will show “00:00”
and the colon between the minutes and
seconds, as well as the four speed
segments, will flash. The rotary switch
should then be turned to the Off
position, “O/Off.” The timer will
automatically turn itself off.
Interrupting or Pausing Timer
The timer function may be interrupted
or paused at anytime by turning the
rotary switch to the Off position, “O/
Off.” The operating time will stop at
the current time. To restart simply turn
the rotary switch back on to the
desired speed. The appliance will then
continue to operate for the remaining
time or until again interrupted.
Stopping Timer Function
The timer function can be turned off at
any time by depressing the “time off”
button, see figure 2b. If the rotary
switch is On, the power unit will
continue to run at the selected speed
until turned off manually.
Electronic Safety Control
The Bosch Concept 7400 Kitchen
Machine incorporates an electronic
safety control to protect the motor. If
the safety becomes activated, the
power unit will shutoff and an error
code will be displayed, see figure 2c,
3. See TROUBLESHOOTING at the
back of this manual if the electronic
safety control should become
activated.
6. Turn power unit off.
When your work with the attachment
is completed or the capacity of the
batch-feed attachment has been
reached, turn the power unit to the Off
position, “O/Off.” If you are using the
timer function, turning the rotary
switch to Off will stop the timer at the
amount of time remaining.
7. Remove the attachment.
Remove the attachment from the
power unit, per instructions for the
specific attachment being used.
