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 resharpening
diagrams, refer to Figure 4.
1. Shut OFF and lockout all power including the main
disconnect switch.
