Maintenance And Cleaning - IKA A 11 basic Mode D'emploi

Remedy (locking):
- Release the On/Off - switch and remove the grinding container.
If fragments of the grinding material have become stuck bet-
ween the grinding tool and the guard ring, do not remove them
until after you have disconnected the power cord.
Caution: 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 maxi-
mum filling height by 50%.
- If you do not release the On/Off - switch and the motor is locked,
the motor circuit breaker will be tripped. Before continuing with
operation allow the mill to cool off.
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 (malfunktion 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").

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 contai-
ner can be cleaned in a dishwasher. If grinding dust is found in the
middle section (the area where presure 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 the pulverization tools"). Then the mill should be pla-
ced on the guard ring (item 8) and the two guide screws (item 22)
should be opened with a hexagonal socket head wrench.
Caution: The mill must be held in place by the drive section during
the opening process, since the middle section and the drive sec-
tion are under spring tension as a result of the pressure spring.
When both screws have been openend, 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.
