2. If the hydraulic motor rotates in reverse, immediately
turn the disconnect switch to OFF and remove power
at the source of electrical supply. Interchange any
two (2) of the three (3) phase electrical supply leads
at the disconnect switch. If any of the three (3)
phase motors runs in reverse (as may occur when
a motor has been replaced), corrective action is to
interchange any two (2) motor leads.
3. If the hydraulic or band drive motor overloads open,
the machine will shut down.
Hydraulic Start-Up
1. All hydraulic and coolant system uid connections
were leak-tested at the factory. They should be
rechecked as start-up proceeds.
Refer to the "Operation" section under "Ma-
chine Controls" on how to operate and select
the keys for the following procedures.
2. Turn on the electrical supply and turn the machine
disconnect switch to ON. The "Start-Up" screen ap-
pears. Press the NextScreen function key to scroll
to the next screen which will shows the HYDRAULIC
PUMP control.
3. Press the "1" key on the numeric keypad to start
the hydraulic system. Then: (a) Press the Next
Screen function key and scroll until the SAW HEAD
control screen appears; (b) Press the "1" key on
the numeric keypad to raise the saw head; (c) If the
hydraulic motor rotates correctly, the saw head will
now raise from the 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 rota-
tion 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 switch;
(c) Restore power and perform Step 3 again.
6. As soon as hydraulic motor rotation is correct, jog
the HYDRAULIC PUMP "1" (start) and "3" (stop)
keys several times to make sure the hydraulic and
coolant pumps are primed. Then allow the machine
to run for several minutes to remove entrapped
air.

bands. DO NOT attempt to remove the saw
band cap while the band drive motor is run-
ning.
1. To remove the protective Saw Cap from the shipped-
in-place saw band, turn the hydraulic system on,
if not already running. Then: (a) Press the Next
Screen function key and scroll until the SAW HEAD
control screen appears; (b) Press the "1" key on the
numeric keypad to raise the saw head and raise to
its maximum height; (c) If the saw head does NOT
raise, press the NextScreen function key and scroll
until the CYCLE MODE control screen appears; (d)
Press the "1" key on the numeric keypad to put the
machine in "manual" mode; (e) Press the Previous
Screen function key to " go "back" to the SAW HEAD
control screen and now raise the saw head.
2. Open both bandwheel doors and nd the ends of
the Saw Cap. Pull the cap off of the saw band. If
the cap is pinched onto the bandwheel, relax the
band tension by turning the band tension handwheel
counterclockwise. The cap now should come
off.
After removal, check to be sure that the saw
band rides properly on the bandwheels (the
back of the saw band must be up against the
wheelange).
3. After removal of the Saw Cap, turning the band
tension handwheel clockwise to apply the correct
band tension (see the "Operation" section for pro-
cedure).
The band drive motor will not start unless: (a)
Both bandwheel doors are closed; (b) The saw
band has been tensioned; (c) Hydraulics are
running.
