The filling grinding container is screwed in onto the drive up to the stop (you can
hear a soft click just before reaching the stop).
When electrical power has been connected, you can begin with the grinding
procedure. Grasp the hood with one hand, press the on/off - switch with your
thumb (figure 2), and the mill starts. Pressing the drive down softly and slowly in
the axial pressing direction forces the pulverization tool into the grinding material
(pressing on one side only can tilt the drive, which could result in premature wear
and tear on the shaft seal).
When the pulverization tool engages the grinding material, the speed of the
motor decreases. The speed decreasing is audible. If the reduction in speed is
very pronounced, the speed of the drive should be increased to be able to insert
pulverization tool into the grinding material at nominal speed. Depending on the
grinding material, it may be necessary to repeat this procedure several times. If
the speed remains relatively constant while the pulverization tool is being lowered
and raised back up, the grinding procedure is complete.
The grinding time should not exceed 30 seconds. Further grinding will not
improve the pulverization of the grinding material, but heating up will increase
considerably.
The appliance is designed for short-time operation. Maximum on-time 1 minute,
minimum off-time 10 minutes. Increasing the on-time or reducing the off-time
can cause the motor to overheat prematurely, which will in turn cause the
appliance to switch off (see Faults and Troubleshooting). The appliance is fused to
protect it in the case of over-use.
Before the grinding procedure is complete, the drive should be raised completely.
Only then should the On/Off - switch be turned off. The advantage of this method
is that the pulverization tool cleans itself. Do not unscrew the grinding container
until the motor has come to a standstill. Any grinding material that adheres to the
guard ring can be swept off on the guard ring into the grinding container with a
cleaning brush (no wire brushes!).
Always remove any grinding scrap which gets into the interstice before using the
appliance again (see ”Maintenance and Cleaning” section).
The grinding tools, the grinding container and the rotor
shaft may be hot. Observe the safety instructions.
WARNING
Commissioning
Check whether the voltage specified on the type plate matches the mains voltage
available.
If these conditions are met, the device is ready to operate after plugging in the
mains plug.
If these procedures are not followed, safe operation cannot be guaranteed and /
or the equipment may be damaged.
Observe the ambient conditions (temperature, humidity, etc.) listed under
“Technical Data”.
The grinding container in figure 1 can be unscrewed and removed by rotating it
counter-clockwise. The drive section can be put down on the guard ring (item 8).
The grinding container is filled with a suitable material. It is essential at this point
not to fill the container higher than the maximum filling height (up to the lower
edge in the grinding container, see figure 1). Filling the container to a higher
level will result in interfering with the operation, which will overload the mill. The
filling quantity can be reduced down to the “uniform grain size“ (in other words
minimum quantities are also possible).
Note:
Smaller filling quantities (for example only about 50 - 80% of the maximum
filling quantity) can be pulverized more quickly, the final granularity is finer,
the range of granularity is smaller and there is less heating up of the grinding
materials. It is better to reduce a large quantity of grinding materials in two or
three portions. The actual grinding time is only barely longer, but the grinding
results are considerably better.
Bulky grinding material (for example hay, etc.) can also be filled up higher than
the lower edge, but no more than about 20 mm below the upper edge of the
grinding container. The loose grinding material is forced into the grinding zone
when the drive is pushed in.
