Cutter Wheel Inspection:
• The steel cutter wheels can be used as long as the teeth can be clearly seen on each cutter wheel and the cutter
wheel edge must be clearly above the drum fl ange edge when pushed towards the drum center. Replace worn
out cutter wheels as a complete set.
• When changing cutters, check drum assembly for cracks or other damage. Replace bent or worn cutter shafts or
cracked drum assemblies. A maximum of 30% wear on shafts before they must be replaced. Excessive vibration
caused by an out of balance cutter head will cause premature failure of the bearings and fatigue cracks in weld
joints and frames. Do not use damaged or unsafe equipment; repair or replace all damaged parts before pro-
ceeding with operations.
