9. Move the clamping lever upwards.
Make sure that the teeth of the toothed belt interlock
with the teeth of the belt clamping device!
10. Then attach the knurled knobs to the holders of the sieve cover!
11. By turning the knurled knobs to the right, tighten the sieve stack
evenly until the toothed belts are tightly clamped!
If the two toothed belts are not evenly clamped, it is
possible that the sieving stock will not be distributed
evenly across the sieve surface.
12. Loosen the sieve tensioning system after sieving:
Unscrew both knurled knobs by turning them to the left in parallel
until the knurled knobs can be removed from the holders on the
sieve cover. Remove the knurled knobs with tension belt fitting
from the clamping lid and place them beside the machine. Take
down the sieve set completely and weigh it.
6.1.2 Multiple sieving
Due to the special shape of the intermediate sieve pan, two or three
sievings (two or three sieve sets on top of each other) can be carried out
in a single step.
Setup example:
Sieve pan with 2 sieves and sample, intermediate sieve pan with 2 sieves
and sample on top of that, the intermediate sieve pan with 2 sieves and
sample material on top of that again.
