9-3 Knife Removal & Adjustment
NOTE: The rotor and bed knives are subjected to severe work and it
is recommended they be inspected periodically for
sharpness. The sharper the knives are kept, the better the
machine will operate and the better the quality of granulate
it will produce. Waiting until the knives have been
severely rounded, chipped, or otherwise damaged will
result in heavy shock loading during operation causing a
subsequent reduction in knife life. For re-sharpening
diagrams, refer to Figure 4.
1. Shut OFF and lockout all power including the main
disconnect switch.
Before undertaking any machine repairs or maintenance, always make certain that
the machine disconnect switch is turned to the OFF position or that the control
enclosure is disconnected from the main power source. When extensive work is
anticipated, either place a sign indicating that the main disconnect switch is to remain
off on the switch or lock the switch to prevent accidental activation by someone
unaware of work in progress.
2. Follow instructions in Section 4 on opening the cutting
chamber.
3. Loosen the fasteners holding the bed knives, shims, and
clamps, working from the knife edges inward to the
center. NOTE the relative position of each part before
they are removed.
4. As the last screw is backed out, the knife clamp, knife
and shim will require some support to prevent them
from moving.
