BAND FILING (Continued....)
Filing Operation
1. Place the transmission gear shift lever in "low" range
before starting the saw band drive motor.
2. Keep these operating points in mind: (a) Keep
the les clean; (b) DO NOT le when the teeth
are loaded; (c) Filing can be performed without
coolant application if the layout lines will be easier
to follow.
3. Clean the le band with a le card and coil it into
no more than three (3) loops before placing it in
storage.
BAND POLISHING
Band polishing option is used on bandwheels
with crowned rubber tires only.

Polishing Guide Set-Up.
2. Lower the post to approximately four (4) inches
(100 mm) above the table. Then: (a) Mount and
track the polishing band in the same manner as le
bands; (b) Tension the polishing band in the same
manner as for a 1/16 inch (1.5 mm) wide carbon
saw band; (c) Install the special table center plate
(larger slot than the standard one).
3. Occasionally rub graphite powder into the polishing
fabric to lubricate and increase band life. Use the
air nozzle to blow away dust while polishing.
DO NOT use coolant with the band polishing
option.
LASER LINE GENERATOR OPTION
To avoid eye damage, DO NOT stare into the
laser beam.
1. A laser devise is used to emit a line on the material
to be cut. This line shows the approximate spot
where the cut will take place.
2. The devise is controlled by a selector switch with
"ON" and "OFF" settings and is located on or near
the control panel. Turn the laser "OFF" when not
in use.
3. The laser is adjustable to position the laser beam
where desirable.
4. When the laser is turned on, a warm-up period of
3 to 5 seconds take place before a line appears. If
the line is difcult to see, darken the work area to
enhance the line.
5. Remove the protective shipping cap from the laser
devise before operation. Replace the protective
cap when not in use.
