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

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 locatet) 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
(Siehe Bild 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.
PLEASE NOTE: The mill must be held in place by the drive sec-
tion 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 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 dishwater The drive section should simply be wiped
clean with a moist cloth. In no case should it be cleaned in water
or in dishwasher.
Assembly:
The pressure spring should be inserted into the middle section so
that it is held into the guide groove. The guide screws should be
screwed in until just after they no longer protrude into the internal
diameter of the middle section.
Now the drivesection should be set in place so that at first the
spring is held in the guide groove and the switch block snaps into
the matching opening in the middle section.

For the switch block to engage completely in place, the drive sec-
tion must be pushedinto the middle section up to the lower stop.
While the drive sections is inserted about half way into the midd-
le section, the guide screws should be tightened.
PLEAS NOTE: The switch block must engage flush in the middle
section in the assembled state. This should always be checked
and if necessary corrected.
Finally the desired pulverization tool is assembled.
Maintenance:
If beaters or blades wear out over the course of time, espicially as
a result of constant grinding of very hard materials, so that rapid
grinding with the appropriate quality is no longer possible, you
need to replace the worn-out parts. Blades can be resharpened
with standard commercially available sharpeners.
PLEASE NOTE: If blades are sharpened with a grinding machine
(wet grinding only is permissible). you should make certain that
the same amount of material is removed on all sides. Otherwise
the blades will become unbalanced.
If more grinding dust settles into the middle section over de cour-
se of time, the seal Item 20 must be replaced.
To do this, you must follow this procedure: (Figure 4)
• Disassemble the middle section as described under „Cleaning.
• Loosen the three nuts Item 13 with a socket wrench.
• Take out the guard ring Item 8 and remove the seal from the
plastic section.
NOTE: Before installing the new seal, make certain that the seal
seat is clean and free of dust. To perform the assembly, place the
middle section on its head.
• Insert the seal. Make certain as you do this that you install it in
the correct direction.
• Now set the o-ring Item 19 in place. Always use a new o-ring.
• Then place the o-ring Item 9 in place, set the guard ring in place
and screw it until it is tight.
