Maintenance
Target group: Operating personnel
Fig.20
The AS200 requires no routine maintenance. When used
in accordance with the instructions, no maintenance or
adjustment work will have to be carried out.
We recommend cleaning the mounting bars from time to
time when using the comfort sieve clamping unit. In
addition, the comfort sieve clamping unit will produce
unavoidable clamping grooves in the mounting bars after a
certain period of time; this grooving can interfere with
proper clamping.
Consequently it is necessary to examine the mounting rods
occasionally to ascertain whether such grooving has taken
place in the clamping area and, if indicated, to rotate the
mounting rods through 90°. A 17 mm open-end wrench will
be required for this purpose.

Loosen the lock nuts indicated by KM. Fig. 20

Rotate the mounting bars through 90°

Re-tighten the lock nuts firmly.
If rotating the mounting bars through 90° fails to move an
area free of grooving into the engagement area, then we
recommend replacing the mounting bars.
During wet sieving, we recommend checking the water
hoses for leaks every three months.
