Knife Mount Surface Inspection - Vermeer BC1200XL Operator's Manual

Knife Mount Surface Inspection

When a cutting knife is removed from the drum, the knife-mounting surfaces on the drum
must be cleaned and inspected.
IMPORTANT: Any debris left on the mounting surface can prevent the knife from lying
perfectly flat on its mating surface. Any dirty or damaged threads will affect the bolt
torque, and prevent the knives from being properly clamped. Either of these conditions can
lead to knife failure during operation.
Thoroughly clean and inspect the following:
• Knife Mount Surface — Remove all wood chips and other material from the
mounting pocket area (1).
• Replaceable Thread Bars (2) — Replace when threads become worn, distorted, or
damaged.
