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.
Spare parts order:
When ordering spare parts, please give:
- Machine type
- Serial number, see type plate.
- Item and designation of the spare parts, see www.ika.com.
Repair:
Please send in device for repair only after it has been cleaned and is
free from any materials which may constitute a health hazard.
For repair, please request the “Decontamination Clearance Certificate” from
IKA, or download printout of it from the IKA website www.ika.com.
If you require servicing, return the device in its original packaging. Storage pack-
aging is not sucient. Please also use suitable transport packaging.
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 drive section 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 section must be
pushed into the middle section up to the lower stop. While the drive sections
is inserted about half way into the middle section, the guide screws should be
tightened.
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, 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.
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 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.
