Precautions Concerning Electronic Condition - Hitachi C 12LSH Technical Data And Service Manual

NOTE: Instruct the customers to align the main unit to the miter angle 0˚ and the bevel angle 0˚ 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 0˚, 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 12LSH)
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 8-8 to reset it.
The digital display may show a deviated value if the flush surfaces for the bevel angle adjustment
bolt are worn.
Instruct the customers to adjust the angle according to section 9-1 in this case.
CAUTION: If the figure shown on the miter angle digital display is different from the positive stop angle
(for example, 45.0˚
slightly from its correct position.
If this happens, do as follows.
(1) Move the turn table left and right with the side handle loosened, and set the turn table to
the correct position.
(2) If the figures on the display and positive stop still do not match, then return the turn
table to the 0˚ position. Next move the turn table left and right with the side handle
loosened as shown in Fig. 50-b. After setting it to the correct position 0˚, press the reset
button again.

8-8. Precautions Concerning Electronic Condition

Operate the machine with correct voltage supply. Large voltage drops caused by an unstable power supply may
cause the lower output of the motor and affect efficient cutting. Advise the customer to check the power supply
before operating the machine. In addition, the customer should be advised to pay particular attention to the
following points:
If an extension cord is used, it should be kept as short as possible and within the requirements listed in the
Instruction Manual "USE PROPER EXTENSION CORD".
[Reason] An excessively long extension cord causes voltage drop.
45.5˚, 31.6˚ 32.0˚) then the positive stop has probably deviated
