DAMAGE CLAIM PROCEDURES VISIBLE DAMAGE AT THE TIME OF DELIVERY: Note damage on carrier’s delivery receipt. Accept the shipment. It can be returned later if repairs are not possible in the field. Request a “damage inspection” from the delivery carrier: The carrier will send his own people or contract an independent agency to make the inspection. The inspector will request a signature on the report and leave a copy. The carrier “damage inspection” report is not final. If additional damage is found when repairs are started, contact the carrier for another inspection; or at least give them the details of the damage. Do not move the equipment from the receiving area and keep all shipping materials until carrier “damage inspection” report is complete. If possible, take photographs of the damage and keep them for your files. Photos could possibly prove a claim at a later time.

SAW BAND PREPARATION (Continued..) Maneuver the saw band into the column guard. Then: (a) Carefully position the saw band around the drive and idler bandwheels with the saw band's back edge resting against each bandwheel's rear flange; (b) Move the Band Tenson selector switch to "tension" to apply just enough tension to hold the saw band in position, then move the selector to the center position to "hold". Slip the saw band between the saw guide inserts by twisting it 90° using the supplied saw band twist tool so the blade teeth are facing the front of the machine and pointing downward. Then: (a) Turn the adjustment screw two (2) full turns clockwse to provide correct pressure against the saw band; (b) Remove the protective Saw Cap from the saw Saw Guide Insert Components.

BANDWHEELS Occasionally check each bandwheel’s back-up flange and wheel tread for wear. Saw bands will not track properly if the taper is worn from the wheel tread. Replace the entire bandwheel if the rim becomes badly worn. Remove the bandwheels every six (6) months to clean them and surrounding areas. At the same time, clean the drive wheel ring gear and pinionbefore appling lubricant. Typical Bandwheel Flange and Tread. On older machines, both bandwheels may have replaceable front flanges to help keep the saw band correctly positioned.
