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.

Fixture options.
Hydraulic Control Panel
1. Band Speed. This keylock adjustment valve allows
the operator to set and maintain innitly variable band
speed between 60 and 300 fpm (18 and 90 m/min.).
Refer to the data plate to the left of the valve for
equivalent band speeds which can be reached with
different valve settings. Turn the knob clockwise
to “increase” the band speed, counterclockwise
to “decrease” it.
• When setting band speed, the operator should try
to obtain a vibration free speed level. Vibration
while cutting generally indicates a need for a lower
speed. If the vibration is severe, retract the saw
head slightly from the stock, then adjust the band
speed and resume cutting.
Typical Hydraulic Panel.
2. Band Feed. This control valve is used to adjust the
saw band's feed force against the workpiece. Feed
force is servo-maintained and innitly adjustable
between 0 and 22 ipm (0 and 558.8 mm/min.). Turn
the knob clockwise to “increase” the band feed,
counterclockwise to “decrease” it. The valve’s
lower locking knob or set screw helps maintain the
setting.
3. Band Feed Gauge. This indicator gauge located
directly above the Band Feed valve registers the
amount of pressure being directed against the
workpiece.
Material Handling Controls
1. Conveyor Speed. This selector switch with "low"
or "1" and "high" or "2" settings regulate the speed
of the conveyor(s).
• When the selector is in the "low" or "1" position,
the conveyor maximum speed is reduced to about
30%.

in conjunction with the Conveyor Speed/Direction
control.
3. Outfeed Conveyor Enable. This selector switch
with "on" and "off" settings allows the operator to turn
the power off or on to the conveyor. This is used
in conjunction with the Conveyor Speed/Direction
control.
4. Conveyor Speed/Direction. This two position
joystick allows the operator to adjust the conveyor
speed and direction of material owing through the
machine.
• The Infeed and/or Outfeed Conveyor Enable
selectors must be "on" for this control to operate.
• Moving the joystick to the right will convey the
material to the rear of the machine; moving the
joystick to the left will convey the material forward
on the system.
• The rate of travel in either direction is controlled by
how far the joystick is moved from center.
5. Workstop. This selector switch with "up", "down'
and "adjust" settings control the position of the
optional workstop.
SAW BAND PREPARATION

2. 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
ange; (b) Move the Band Tension 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".
3. 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 clockwise
to provide correct pressure against the saw band;
(b) Remove the protective Saw Cap from the saw
band; (c) Close the the upper bandwheel door; (d)
Move the Band Tension selector switch to "tension"
to apply full tension to the saw band.
4. Turn the Band selector switch to "run" and operate
at a very low speed to check for proper band tracking
against the each bandwheel rear ange.
Band Tension Adjustment
1. Located on the rear side of the column and accessed
from the left side, band tension is hydraulically
applied and maintained.
DO NOT operate the band drive motor unless
band tension selector is in the "tension"
position.
POST ADJUSTMENT
1. Post and upper saw guide height is regulated by
the Post selector switch on the control panel.
2. Sawing results will generally be more satisfactory if
the post and upper saw guide are kept as close as
possible to the material being cut. Doing so helps
reduce saw band vibration and contributes to more
accurate sawing.
The post can be lowered only when the saw
head is fully retracted.
When the saw head has been tilted, make sure
the post and saw guide will clear the material
and/or the vise jaws.

HEAD REVERSE RATE
1. Located on the left side of the control console, this
valve is used to regulate the reversing speed of
the saw head. Turn the knob counterclockwise
to “increase” the reversing velocity; clockwise to
“decrease” it. The valve’s lower locking knob or set
screw helps maintain the setting.
2. It can also be used to withdraw the saw band from
its kerf during a binding or jamming situation To
do so: (a) Turn the Band selector to "stop" if the
saw band is stalled; (b) Turn the Feed selector to
"auto-off"; (c) Turn the Head Reverse Rate knob
clockwise to the minimum rate and move the Feed
selector to "reverse".
3. Very gradually increase the head reversing rate by
turning the control knob counterclockwise to allow
the carriage to slowly retract and withdraw from its
kerf.
HEAD TILT ADJUSTMENTS
1. The saw head can be tilted up to 45° left or right for
angular sawing and controlled by a selector switch
on the pushbutton panel. Tilt angle is indicated by
the Miter Meter, or on older machines, a protractor
scale and pointer located on the rear right side of
the roller table behind the sawing head.
2. The sawing head must be in the fully retacted
position in order to tilt the head. (a) Turn the
Operation selector to "set-up"; (b) Turn the Feed
selector to "reverse" to fully retract the head; (c)
Turn Tilt selector to "left" or "right" as desired and
then turn to "hold" when desired angle is achieved
as indicated on the Miter Meter, or the protractor
scale and pointer.
When the saw head is tilted, make sure the
post and upper saw guide is positioned to
clear the material and/or vise jaws. Failure
to do so will result in damage to the post.
MITER METER
1. This angle measuring devise is mounted to a bracket
on the left side of the control console. The battery
operated unit has a "power on" thumbwheel or button
and a LCD readout window to display the tilt angle
of the saw head.
2. When tilting the head to the left, the LCD will display
the angle with a minus (-) sign in front of the value.
When tilting to the right, there will be no sign in front
of the value.
Eliminate any electromagnetic radiation from
such things as radio transmitters, walkie-
talkies, etc. which may affect the angle data
shown on the display.
ROLLER TABLE
1. Material is supported on the table by four (4) rollers
on each side of the saw band. Rollers have sprockets
and are chained together for ease of moving material
into cutting position. Material movement is done by
means of a hand crank (hand crank is also used for
chip conveyor) that ts onto a tting on the far right
or far left roller.
Roller Table.
2. Maximum table support weight is 6000 pounds
(2721.6 kg) evenly distributed with no impact.
VISE ADJUSTMENTS
1. The 12.50 inch high (317.5 mm) vise jaws are
mounted on the left side of the saw band and
controlled by a selector switch on the pushbutton
panel.
2. To adjust the movable jaw: (a) Lift up and hold the
locking lever; (b) Slide both the vise jaw and vise
lock toward the workpiece; (c) Locate the pin into
the nearest hole in the vise slide bar by releasing
the locking lever; (d) Turn the Vise selector switch
to "close".
