Bolt Inspection - Vermeer BC1200XL Operator's Manual

Bolt Inspection

WARNING: Incorrect maintenance and torquing of the knife-mounting bolts can cause the knives to become detached
from the cutter drum. Death or serious injury is possible if the failed knives are ejected from the machine and strike
someone. Extensive and costly damage to the cutter drum and machine will probably occur if the knives become
detached.
WARNING: Knife-mounting bolts must be replaced each time knives are sharpened or replaced. Bolts may be reused
ONLY ONCE when rotating knife to its second cutting edge. Failure to replace bolts can cause knife/drum separation
resulting in death or serious injury, and machine damage.
WARNING: Overtightened bolts can cause knife distortion, allowing wood to pack under the knife. Distorted knives
can crack and fail resulting in death or serious injury, and machine damage. Use a straightedge and check all knives
for distortion; discard any that are distorted.
IMPORTANT: When installing a new or sharpened set of knives, discard the existing mounting bolts
and use new Vermeer-approved bolts. Repeated reuse of the bolts will decrease their clamping
capacity each time the bolts are torqued. Inadequate clamping of the knives will cause the knives to
loosen and fail.
Bolts —Inspect bolts (1) for damaged threads, corrosion, and distortion. If any are found, discard
the bolt and install a new one.
