ly, the activation to be continued until the bowl has reached its top position. When the
bowl is approx. 10 cm from its top position, the tool will start to rotate in low speed. The
rotation of the tool and the bowl will stop automatically when the bowl is in its top posi-
tion.
The red diode in “Start/Stop” field is now alight to show that the mixer is ready.

4.1.2 Starting the mixer
Activate the field “Start/Stop” to start the mixer.
Activate the field “speed up” to increase the speed.
Activate the field “speed down” to reduce the speed.
The speed indicator below the fields “1” to “4” shows the mixing speed of the tool.
4.1.3 Four fixed speeds
For quick choice of speed, use the fields “1” to “4”.
Field “1” corresponds to the lowest speed.
Field “2” corresponds approx. to 30% of maximum speed.
Field “3” corresponds approx. to 60% of maximum speed.
Field “4” corresponds to maximum speed.
If it is possible to change the fixed speeds - see the paragraph “Change of fixed speeds”.
4.1.4 Indication of operation time
Before starting the mixer, an operation time for the mixer can be chosen by adjusting the
time on “time down” and “time up”. If the field is activated for longer time, the speed is
increased/reduced quicker.
Minutes and seconds are shown in the text field between “time down” and “time up”.
4.1.5 Automatic lowering of bowl
When an operation time has been indicated and the mixer has been started, it is possible
by activating the field “bowl down” to lower the bowl automatically when the operation
time has run out. the diode in the field is flashing after the activation.
4.1.6 Inspection of the ingredients during operation
If it is wished to stop the mixer without reducing operation time and speed, the field
“pause” can be activated. the mixer will reduce speed and then stop, the operation time
will also stop.
It is now possible to open the safety guard to check the ingredients.
Close the safety guard and activate the field “Start/Stop”, and the mixer will start and will
increase the speed to the speed chosen before “pause” was activated. The operation time
will continue when the mixer has reached the chosen speed.

4.1.7 Lowering of bowl
When the ingredients in the bowl have been mixed, the mixer is stopped by activating the
field “bowl down”. When the bowl has reached its bottom position, the safety guard can
be opened.
4.1.8 “JOG” function
The mixer is provided with a “JOG” function. Before the bowl reaches its top position,
the tool starts rotating to dig its way into ingredients. For safety reasons the “JOG” func-
tion means that two hands must be used to operate the mixer.
4.1.9 Overload
Do not overload the mixer. Sticky and heavy dough may reduce the capacity of the bowl
by 75%. The capacity is further reduced if the speed of the mixing tool is increased be-
yond the recommended values or if a wrong mixing tool is used. large lumps of fat or
cooled ingredients must be cut into small parts before they are placed in the bowl.
Prolonged overload will make the mixer’s motor protection disconnect the mixer. Leave
the mixer for approx. 3 minutes and restart it again as described under “Procedure in case
of overload”.
4.1.10 Procedure in case of overload
• Push emergency stop
• Open the safety guard
• Empty the bowl
• Close the safety guard and release the emergency stop
4.1.11 Changing of fixed speeds
For the fields “2” and “3” it is possible to change the speed for future mixing jobs. Acti-
vate the field “speed down” or “speed up” to adjust the speed down or up. If required to
store the adjusted speed, activate the field “2” or “3” for a minimum of 5 seconds until the
diode in the speed indicator is flashing.
The adjusted speed has now been stored in the memory.

4.1.12 Inductive sensor
At the back of the right bowl arm is an inductive sensor (Fig.1) which is activated when
the bowl is placedcorrectly in the bowl arms (all the way back in the bowl arms). the mix-
er can only be operated when the sensor is activated.
It is possible to lift the bowl arms even if the bowl is not mounted.
The bowl arms can move a little in case of maximum loading (mixing of dough), this is
intentional from the designer.

4.1.15 Correct use of tools
Whips should not struck against hard objects as e.g. the edge of the bowl. This will make
the life of the tool shorter due to increasing deformity.
For production of mashed potatoes the special wing whip should be used, not the standard
whip.
4.2 After use
4.2.1 Cleaning
The mixer should be cleaned daily or after use.The mixer should be cleaned with a soft
cloth and clean water. Sulphonated soaps should be used with caution as they destroy the
mixers lubricants.
Never use high pressure cleaning for the mixer.
Bowls and tools of aluminium must not be washed with strong alkaline detergents (pH not
bigger than 9.0)
