4.
The back edge of the saw band should just touch
the back-up flange of the saw guide rollers, or the
back-up bearings on insert type saw guides.
5.
Close both bandwheel doors.
SAW BAND PREPARATION
Information about any DoALL saw bands
and their applications can be obtained from
a DoALL sales representative.
Saw Band Selection
1.
The standard machine is equipped with a friction
saw band that is 234 inches (5343.6 mm) long. It
will accept saw band widths from 1/16 to one (1)
inch (1.6 to 25.4 mm). Extra work height machines
requires longer saw bands.
2.
Optional saw guides that can be used:
•
One (1) set of double row, heavy duty ball bearing
saw guide with rollers for one (1) inch (25.4 mm)
wide saw band. Rollers for saw bands 1/4 to 3/4
inch (6.3 to 19.0 mm) are also available.
•
One (1) set of insert-type precision saw guide blocks
with inserts for saw bands from 1/16 to 1/4 inch (1.6
to 6.3 mm) wide.
Roller-Type Saw Guide Adjustment-Type III
These instructions apply to both the upper
and lower roller-type saw guide blocks.
1.
Select the saw guide blocks and rollers marked
for the width of the saw band to be used. Then:
(a)
Place one (1) side roller and one (1) back-up
roller in the upper saw guide block;
(b)
Switch the
rollers around for the lower saw guide block;
(c)
Install the special adaptors onto the post and table
cradle;
(d)
Then install the saw guide blocks on the
adaptors.
2.
After the saw guides are in place, the saw band
should be in place and tensioned. See later in
this section on installation and tensioning the saw
band.
3.
Loosen the clamp screws and bring the rollers up to
the saw band, then tighten the screws. The rollers
should be free enough to turn without moving the
saw band.
BAND SPEED CONTROL
1.
Speed range can be infinitely varied with the
Band
Speed
control. The speed is shown on an display
located above the control.
2.
Band speed is changed by turning the
Band Speed
control to the desired speed as indicated on the
band speed display.
4.
During machine operation, keep the following band
speed precautions in mind:
Adjust the band speed only while the machine
is running.
Always turn the band speed control to “slow”
before stopping the machine.
Always allow the saw band to stop completely
before opening any bandwheel doors.
SAW BAND TENSION HANDWHEEL
1.
Saw band tension is adjusted by turning the
handwheel located below the machine’s sawing
head.
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.
Optional hydraulic band tension is factory set.
DO NOT adjust the handwheel if supplied!
SAW BAND TRACKING LEVER
1.
The upper bandwheel can be tilted a maximum of
five (5) inches (127.0 mm) forward and backward to
help obtain correct saw band tracking. This is done
by the use of the bandwheel tilting lever located
behind the band tension handwheel. A saw band is
tracking properly when the saw band center follows
the center of both crowned bandwheel tires.
2.
The following tracking procedures are to be
performed with the band drive motor "OFF":
(a)
Open both bandwheel doors;
(b)
Manually turn
the bandwheels to observe how the saw band is
tracking.
3.
Move the bandwheel tilting lever to adjust the
position of the bandwheel; to the left to track the
saw band “IN”; to the right to track the saw band
“OUT”.
