a As the crusher is operated, the teeth become
worn, so the value displayed on clearance dis-
play monitor (A) gradually becomes different
from the actual clearance. When this happens,
it is possible to compensate for the value by
keeping crusher clearance decrease switch (4)
pressed to bring the teeth into contact with the
fixed jaw plate.
1. Keep crusher clearance decrease switch (4)
pressed to bring the movable teeth and fixed
jaw plate into contact.
When the value (A) shows no more change,
the movable teeth and fixed jaw plate are in
contact.
2. After bringing the movable teeth and fixed jaw
plate into contact, keep crusher clearance
decrease switch (4) pressed for approx. 10
seconds.
3. The buzzer sounds and the compensation is
completed.
When this happens, the value on crusher
actual clearance monitor (A) changes to 0.
a Depending on the wear of the teeth, the
v a l u e a f t e r c o m p e n s a t i o n m a y n o t
become exactly 0, but this does not indi-
cate any abnormality.
4. Press crusher clearance increase switch (5) and
adjust so that the value on crusher actual clear-
ance monitor (A) becomes the target value.
