Sieves – Basic setting
(electric sieve adjustment – from serial no. ...)
If the rods have been adjusted, the basic setting of the
sieves has changed and must be reset.
This is done as follows:
1. Remove ball head (T) from sieve adjusting lever.
2. Using the rotary switch and +/– keys, move the
sieve adjusting linkage to the “0” position.
3. Fully close the sieve openings.
4. Slacken off the lock nut (K).
5. Adjust ball head (T) so that it may be put in place
without stress. Bolt down ball head and tighten
lock nut (K).
6. Check if the frogmouth sieves have identical
positions.
Open sieves, e.g. to position “15”.
Openings of the left-hand frogmouth sieve must
be identical with the openings of the right-hand
frogmouth sieve.
To check the frogmouth sieve openings use a
gauge (CLAAS special tool, part no. 181 625.0) if
necessary.
With this gauge the lower sieves can be checked
too. But the upper sieves must then be in the fully
open position.
If necessary, set the frogmouth sieves by
adjusting the rods. Make sure sieve openings are
not set too narrow.
To adjust the finishing sieves for identical
openings, one of the upper sieves has to be
removed.

Removing the upper sieves
(up to serial no. ...)
Remove connecting linkage (G). For this unscrew the
ball head joints on the adjusting levers of the sieves.
