etc.
3. Start the hydraulics. Then raise the saw head. If
the hydraulic motor rotates correctly, the saw head
will now raise from the full down position.
4. If the saw head does not raise, it means that the
hydraulic motor’s rotation is reversed (this can
be veried by observing motor rotation). Motor
rotation must be according to the arrow on the
pump body. Hydraulic system operation cannot
be maintained if the saw head is not raised.
5. If hydraulic pump motor rotation is reversed: (a) Turn
the disconnect switch to "OFF" and remove power
at the source of electrical supply; (b) Interchange
two (2) of the L1, L2, or L3 leads to the disconnect

band from around the drive bandwheel; (c) Work the
saw band's upper strand through the upper blade
guard above the saw guide arms; (d) Move the saw
band down and under both saw guide arms.
Immediately store or dispose of the old or
broken saw band. If possible, recoil the saw
band into the original holder before scrapping
it.
Saw Band Installation
Always use extreme care when handling saw
bands. Wear gloves.
1. Remove the old or broken saw band as described in
the previous section. Clean metal chips and other
foreign materials and debris from around the saw
guides and both bandwheels.
2. Form the saw band into one large loop. Then:
(a) Slip the saw band under the saw guide arms
and into approximate position for placement; (b)
Work the saw band into the upper blade guard. (c)
With the saw band's teeth facing towards you, slip
the looped saw band around the drive and idler
bandwheels.
3. Twist the saw band 90° so that its teeth between the
saw guide arms point down and to the right. Then:
(a) Insert the saw band into the saw guide inserts
and pull up against the back-up bearing; (b) Check
the saw band's position around the bandwheels (its
back edge must rest against each bandwheel's rear
ange).
4. Apply correct band tension by turning the band
tension handwheel clockwise. Then: (a) Remove
the new saw band's protective cap; (b) Turn the saw
guide insert adjustment screws clockwise until tight
(do not over tighten); (c) Turn each adjustment
screw back counterclockwise a 1/4 turn.(d)
Reposition or mount the band brush and reinstall
both blade guards; (e) Close both bandwheel
doors.
Band Tension Handwheel
1. Band tension is applied by turning the handle which
protrudes from the saw head's right side. Turn the
handwheel clockwise to "increase" band tension;
counterclockwise to "decrease" it.

Turn Handle to Set Band Tension.
2. Correct band tension for the machine's standard 1-
1/4 inch (31.7 mm) wide by 0.042-inch (1.067 mm)
gage saw band is 4.0 units or 30,000 psi (2115 kg/
cm²) measured by a DoALL Tensigage. This tension
setting is established when the factory preset stop
bolt contacts the large washer. An escutcheon near
the band tension handwheel describes the washer
to stop bolt relationship in a setting of 30,000 psi
(2115 kg/cm²).
DO NOT start the band drive motor unless the
saw band has been properly tensioned.
3. Important factors which inuence band tension
settings are the size of stock to be cut and desired
band life. General rules-of-thumb are: (a) Lower
tensions will increase saw band life; (b) Greater
tension is required as spacing is increased between
the saw guide arms; (c) Higher band speeds require
greater tension.
SAW GUIDE ARM ADJUSTMENT
1. From the rear of the machine, the right saw guide
arm is xed. The left saw guide arm can be adjusted
as follows to accommodate varying stock widths: (a)
Loosen the left saw guide insert adjustment screw
by turning counterclockwise;(b) Loosen the left
arm's locking knob by turning it counterclockwise;
(c) Move the arm along the slide bar until it is as
close as possible to the stock without making
contact with the stock when the head is raised or
lowered; (d) Turn the locking knob clockwise to
tighten; (e) Tighten the insert adjustment screw as
previously instructed.
DO NOT move the left saw guide arm while
the saw band is running.
2. The best cutting results are generally obtained
when the saw guide arms are positioned as close
as possible to the stock.
WORK HEIGHT ADJUSTMENT
1. The work height mechanism works in conjunction
with the head clear proximity switch (1 PRS) to
assure that the saw head has raised sufciently
above the stock so manual stock positioning can
be accomplished safely.
Work Height Adjustment.
2. To adjust, lower the saw head all the way. Then:
(a) Loosen the lock knob; (b) Rotate the adjustment
ag to the desired work height indicated with the
pointer; (c) Tighten the lock knob.
3. There is a convenient metric equivalent chart for
converting the work height to millimeters.
SAW HEAD POSITIONING FOR ANGLE CUTS
1. To position the saw head for angle cutting from 0° to
60°: (a) Loosen the head swivel clamping handle,
located below the pivot weldment, by turning it
counterclockwise; (b) Pivot the saw head to the
desired angle as indicated by the pointer located
below the handle; (c) Turn the handle clockwise
to "LOCK" the saw head in place.
The capacities of the machine are reduced
when angle cutting.
2. The 0° and 60° angle positions have been preset
at the factory. If adjustment becomes necessary, it
can be made with the screws and jam nuts located
on the front of the pivot weldment.
