REF functions (temporary referencing the blade location)
REF1 and REF2 functions, as mentioned ealier in this section, are typically used when
sawing a log down to a cant, i.e., until all four sides of the log are flat.
With a new log loaded and clamped in position on the sawmill bed, press the white
HEAD/BED button to activate HEAD mode. The yellow HEAD
light will come on.
The joysticks can now be used to control all saw head functions.
Then push the white MANUAL button to turn Manual mode on (manual saw head control).
The button will illuminate.
Using the left joystick, position the saw head at the height where you want to make the
first cut on the first side of the log.
Instead of the MANUAL button, you can press REF1 or REF2 button (
REF LOCK
disabled
) to position the blade for the first cut on a given side of the log.
NOTE: Do not use the MANUAL button after making cuts on the first two sides
of the log; this will clear all stored references.
After the blade has been positioned for
the first cut, press REF1 button (if it has
not been done ealier),
REF LOCK
button and REF1 button again.
The REF1 button will start flashing
(NEXT CUT ON)
. Once the REF LOCK
button is pressed, the current blade
position is stored in the computer
memory. The computer will reference
this position when raising or lowering the
saw head for the next cut.
Press the START/STOP button to turn the blade motor on. Then make the first cut.
To do this, pull the right joystick toward you. While making the cut, adjust the blade speed
by turning the feed rate dial located at the left of the control box.
As soon as the blade exits the log and the board return fingers drop down at the end
of the log, press the top button on the left joystick (BUMP UP button). This will raise the
saw head to a height allowing to drag the board/slab off when the head is being returned.
If you want the saw head to be raised higher, press the top-left joystick button two or more
times. The BUMP UP height (a distance by which the saw head can be automatically
raised after each cut) can be adjusted in the Settings menu (initial programming mode)
(
NOTE:
If the slab is too small to drag back, pull the left joystick toward you to raise the
