Never clean in water or in a 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.
Caution: The switch block must engage flush in the middle sec-
tion 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, especially
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.
Caution: 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 the
course of time, the seal (item 20) must be replaced.
To do this, you must follow this procedure (see figure 4):
• Disassemble the middle section as described under „Cleaning
and maintenance"
• 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.
