About the Hopper
See the figure below for identification of Hopper assemblies.
Important:
Do not put Magnetized Screws in Hopper. Magnetized
screws can cause sluggish response to screws getting
stuck. Hopper plates could get magnetized and will have
to be demagnetized with a degausser.
Important:
Do not adjust any of the Hopper air cylinders. They are adjusted at the
factory. Any adjustment may cause timing issues with the operation of
the Eight Shooter. If you think problems are being caused by the cylin-
ders, please contact the KVAL Service Department for direction.
Important:
Do not mix screw types in the Hopper. Different sizes, pitches can cause
uneven application of the hinge.
