Outlet clearance adjusting method
When the machine is used continuously, wear of
the addendum will cause the crusher outlet clear-
ance to become larger, and the size of the particle
will become coarser. If the crushed particles are
remarkably worse than when the clearance was
last adjusted, adjust the clearance as follows.
The crusher outlet clearance is adjusted by extend-
ing or retracting the lock cylinder.
On this machine, there are three types of clearance
adjustment function.
A (Automatic):
T h e c l e a r a n c e i s a u t o m a t i c a l l y
adjusted according to the set value
input on the clearance set monitor.
S (Semi-automatic):
T h e c l e a r a n c e i s a u t o m a t i c a l l y
adjusted by inputting the desired value
for change on the clearance set moni-
tor. (If the input value is (+), the clear-
ance becomes larger; if the input value
is (–), the clearance becomes smaller.)
M (Manual): It is possible to adjust the clearance
manually by using the panel switch.
k
Start the engine. For adjusting the outlet
clearance, set the travel lever lock to the
LOCK position without fail.
k
Be sure to attach a warning tag to the start-
ing switch in the control box.

ing operation to bring the position of the flywheel to
the center of the adjustment range on the right to
position it before adjusting the outlet clearance.

Before starting operations, check that there
is no one inside the crusher or in the sur-
rounding area.
k
When the machine is shipped from the fac-
tory, the clearance is set to 50 mm (O. S. S.),
so adjust the discharge clearance to the
desired size or size suitable for the material
being crushed.
k
O. S. S. means the condition when the
c r u s h e r d i s c h a r g e c l e a ra n c e i s f u l l y
opened.
k
Always be sure to check that the crusher
chamber is empty and that there is no mud,
sand, or soil stuck to the teeth.
