The shaft of the grinding container and the pulverization
tools may not be hot. If necessary, allow the mill to cool off.
- Fill the grinding container with a sufficient amount of pre-reduced grinding
material.
- Do not exceed the maximum filling hight in any case.
- In the case of hard or tough grinding material, reduce the maximum filling
height by 50%.
- If you do not release the On/Off - switch and the motor is locked, the motor
circuit breaker or the circuit breaker (at 100-115V) will be tripped.
- Before continuing with operation allow the mill to cool off or reset the circuit
breaker.
The drive suddenly cuts out during the grinding procedure:
Causes:
- Overheating of the drive (malfunction display lights up when the On/Off - switch
is pressed, parts of the housing are warm).
- The grinding container has rotated itself loose and has triggered the circuit
breaker (malfunction display lights up when you push the On/Off - switch).
- The power supply has been interrupted.
Remedy:
- If the mill has overheated, wait a few minutes.
- Screw in the grinding container up to the stop.
- Check the power supply.
The lifting motion is blocked:
Causes:
- The middle section is dirty.
Remedy:
- Clean the middle section (see the section entitled „Maintenance and cleaning“).
If this occurs quite often, you should check the seal (item 20), (if necessary, replace
the seal as described in the section „Maintenance and cleaning“).
WARNING
Maintenance and cleaning
Cleaning:
Unplug the power cord before all cleaning tasks!
Dirty parts in the pulverization area can be cleaned with a cleaning brush. If there is a
heavy accumulation of dirt, the grinding container can be cleaned in a dish-washer.
If grinding dust is found in the middle section (the area where pressure spring is
located) it can be blown out through the opening with compressed air.
If there is a heavy accumulation of dirt on the guard ring and the middle section can
be disassembled as follows (see figure 4).
First, the pulverization tool must be disassembled. (See “Exchanging and replacing
the grinding tools“). Then the mill should be placed on the guard ring (item 8) and the
two guide screws (item 22) should be opened with a hexagonal socket head wrench.
Note:
The mill must be held in place by the drive section during the opening
process, since the middle section and the drive section are under spring tension as a
result of the pressure spring. When both screws have been opened, the drive section
can be pulled away from the middle section. The switch block (item 15) remains on
the drive section.
The middle section and if necessary the pressure spring can be cleaned in a
dishwasher.
The drive section should simply be wiped clean with a moist cloth. Never clean in
water or in a dishwasher.
Use only cleaning agents which have been approved by
IKA
to clean the device: Water
containing surfactant / isopropyl alcohol.
- Wear protective gloves while cleaning the devices.
- Electrical devices may not be placed in the cleansing agent for the purpose of
cleaning.
- Do not allow moisture to get into the device when cleaning.
- If a different cleaning or decontamination method than the method defined
by
IKA
is planned, the user must ascertain with
IKA
that this method does not
damage the device.
