ADDITIONAL MANUAL CONTROLS
HEAD RETRACT LIMIT OVERRIDE:
This button overrides the head retract limit switch to allow the head to retract further in order
to allow easier blade removal. Depressing this button will also permit the head to be advanced
without starting the blade.
HEAD SWING LEFT:
Depressing this button fully will cause the head to swing quickly to the left until the button is re-
leased or the head reaches the swing limit. Depressing this button partially will cause the head
to swing slowly to the left allowing for ne adjustment. The head will only swing when the upper
guide arm is fully up and the head is fully retracted.
HEAD SWING RIGHT:
Depressing this button fully will cause the head to swing quickly to the right until the button is
released or the head reaches the swing limit. Depressing this button partially will cause the
head to swing slowly to the right allowing for ne adjustment. The head will only swing when the
upper guide arm is fully up and the head is fully retracted.
GUIDE ARM:
This switch controls the vertical position of the upper guide arm. Guide arm position is very
important when cutting as well as aecting the blade life. Placing the upper guide arm as close
to the work as possible improves cut accuracy, blade life, and safety (because less blade is left
exposed above the work piece). The guide arm must be fully raised before the head can be
swung.
BLADE TENSION:
The Blade Tension switch is located on the side of the electrical enclosure, and its used when
adjusting or changing the blade which is detailed in Section 3 of this manual. During cutting the
Blade Tension switch must be in the “+ RUN” position.
BLADE CHANGE KEYLOCK
This lock is provided for the safety of the operator during the blade changing procedure When
the lock is in the “ON” position, the hydraulics may be started with the side covers and the drive
box door open, and the only functions that are active are HEAD, GUIDE ARM and BLADE
TENSION controls. When the blade has been changed, the lock must be switched to the “OFF”
position in order to operate the machine.
