DAMAGE CLAIM PROCEDURES
VISIBLE DAMAGE AT THE TIME OF DELIVERY:
1. Note damage on carrier’s delivery receipt. Accept the shipment. It can be returned later if repairs
are not possible in the eld.
2. Request a “damage inspection” from the delivery carrier:
a. The carrier will send his own people or contract an independent agency to make the
inspection.
b. The inspector will request a signature on the report and leave a copy.
c. The carrier “damage inspection” report is not nal. 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.
3. Do not move the equipment from the receiving area and keep all shipping materials until carrier
“damage inspection” report is complete.
4. If possible, take photographs of the damage and keep them for your les. Photos could possibly
prove a claim at a later time.
5. Keep a record of all expenses and be sure they are documented.
6. Repair damage in the eld whenever possible. Carriers encourage this to keep expenses down.
7. You have nine (9) months to le a claim.

OPERATION
SAFETY PRECAUTIONS
Warning Label - READ and UNDERSTAND.
FRICTION SAWING
1. The design of this machine makes it ideal for
friction sawing. In friction sawing, momentary
contact between the material being cut and the
fast moving saw band produces enough friction to
heat the material to its softening point. As soon
as it becomes soft, it is cut away by the saw band
teeth. This method cuts many times faster than
conventional methods and cuts many materials that
can not be machined any other way.
2. Keep these important points in mind while friction
sawing:
Roller saw guides are required for friction
sawing.
Attach the spark shield to the post is necessary
for friction sawing. Coolant is not used.

Saw Band Tension Adjustment
1. Saw band tension is adjusted by turning the
handwheel located below the machine’s sawing
head.
Optional hydraulic band tension is factory set.
DO NOT adjust the handwheel if supplied!
2. A scale showing the recommended tension for
various saw band widths is located to the right of the
tension adjustment handwheel near the post. Scale
numbers represent the recommended tensions for
common saw band gages and pitches.
