ve the hexagonal nut Item 24with the second single-head wrench
and remove the blade or the beater.
Before assembling a new or another pulverization tool, make cer-
tain that all parts are clean. It does not matter which direction bea-
ters and blades are installed in. Due to their double-sided operati-
on, the two pulverization tools have a service life that is twice as
long. If one side is dull or worn, you can use the other side by tur-
ning the beather or blade around.
After you have set the pulverization tool in place, tighten the hexa-
gonal nut to finger thightness. To do this, use the tools as shown
in Figure 3.

Malfunctions and eliminating malfunctions

Malfunction display:
The malfunction display lights up if the grinding container has not
been screwed in to the stop and the On/Off switch has been pres-
sed.
The malfunction display also lights up if the motor circuit breaker
has been triggered and the On/Off switch is pressed. The malfunc-
tion display alone does not indicate which of the two possible errors
has occurred. As a rule, if the motor circuit breaker has been enga-
ged, an elevated temperature has been detected on the mill hou-
sing.
Temperature and over-current protection
The A11basic mill is protected from overload and/or overheating by
a combined temperature and overcurrent switch..
The motor circuit breaker turns itself back off automatically when
the temperature of the mill is again in an acceptable range and the
On/Off key has not been pressed. This may be after only a few
seconds in the caseof a short-term overload. If the mill has heated
up a great deal after an extended period of operation, it may take
up to 30 minutes to cool off.

You should not press the On/Off key repeatedly during the cooling
off phase, since the motor circuit breaker is equipped with an auto-
hold function that prevents the mill from starting up again it if
On/Off key is pressed repeatedly. To determine whether the mill is
ready to start up again, you should press the On/Off switch at inter-
vals of from 5 to 10 minutes. If the malfunction display lights up
again while the grinding container is screwed on, the temperature
is still too hot (maximum cooling-off time: 30 minutes at an ambient
temperature of about 25°C).
Eliminating malfunctions:
The mill does not start up:
Causes:
- Power cord is not plugged into the socket correctly
- You did not push the On/Off switch down far enough
- The grinding container is not screwed in up to the stop (when
you press the On/Off key the malfunction display lights up)
- The mill has been heated up by the previous grinding procedure
(the malfunction display lights up when you pres the On/Off key)
- After disassembling the middle section (for example to clean it)
the switch block is not completely engaged
Remedy:
- If necessary, check the power supply and the power cord
- Push the On/Off switch down until you hear an audible „click"
If the malfunction display lights up when you push the On/Off
switch:
- Screw the grinding container up to the stop (a soft „Click" is
audible) and if necessary remove any dirt from the threading
- Check to make sure the switch block is engaged in place
- If the mill has overheated, wait a few minutes for it to cool down
