MAKE SURE THE MACHINE HAS BEEN TURNED OFF AND UNPLUGGED FROM THE POWER SOURCE BEFORE PERFORM-
ING ANY MAINTENANCE OR ADJUSTMENTS.
HELICAL CUTTER HEAD INSERT REVERSAL / REPLACEMENT (MODEL 30-360HC ONLY)
To be sure that the inserts are in good condition, simply make a visual inspection by manually turning the cutter
head.
There are 58 reversible carbide inserts (knives) B installed in the helical cutter head A (#360H) at the factory. With
use and normal wear over time, it will eventually become necessary to reverse and/or replace the inserts.
To maintain even insert wear always reverse or replace all 58 inserts each time knife replacement is required. When
needed, replacement inserts B can be ordered through your local General International distributor under part
#30-443 (sold by sets of ten).
