(1) Turning on the digital display switch shows 0û for both miter and bevel angle, regardless of main unit angle.
(2) Align the main unit angle with the tilt angle (0û) and miter angle (0û) and hold down their reset buttons for at
least 0.2 second.
(3) Turning on the laser marker switch while the digital display switch is on, lights up the laser marker. (On the
Model C 12FCH, only the laser marker switch.)
CAUTION: When operating the digital panel, have the motor head section at the top limit position
and the blade stopped.
NOTE: Instruct the customers to align the main unit to the miter angle 0û and the bevel angle 0û and hold
down their reset buttons for at least 0.2 second before starting to cut. If customers press the
digital display switch to ON without aligning the main unit to 0û, then the figures appearing on
the digital display and the main unit angle will not match.
The laser marker will not light up if the digital display switch is turned off. (only Model C 12LCH)
Do not use the main unit near equipment that generates electrical noise such as generators.
Electrical noise might cause faulty readings or operation on the digital display.
If there is a malfunction on digital display because of power supply noise, turn the digital display
switch OFF and perform the procedures (1) and (2) in 8-5 to reset it.
The digital display may show a deviated value if the flush surfaces for the bevel angle
adjustment bolt are worn (plates (A) and (B) in Fig. 15-2). Instruct the customers to adjust the
angle according to section 9-1 in this case.
