Precautions Concerning Electronic Control - Hitachi C 10FSB Technical Data And Service Manual

Position crown molding with its WALL CONTACT EDGE against the guide fence and its CEILING CONTACT
EDGE against the crown molding stoppers as shown in Fig. 49-2. Adjust the crown molding stoppers
according to the size of the crown molding. Tighten the 6-mm wing bolt to secure the crown molding stoppers.
Refer to Table 11 below for the miter angle.
For inside corner
For outside corner
Use sub fence (A) (optional accessory) to secure the crown molding more firmly.
(Refer to the Instruction Manual "Confirmation for use of sub fence (A)".)

8-8. Precautions Concerning Electronic Control

Operating the Models C 10FSH and C 10FSB near an electric welding machine may cause fluctuations in the
rotation speed. The control circuit in the Models C 10FSH and C 10FSB contains a magnetic sensor (a flux
change detecting element) and a triac (control element of power supply voltage waveforms). Accordingly,
customers should be advised not to operate the Models C 10FSH and C 10FSB in the immediate vicinity of other
machines that generate extremely strong magnetic fields or excessive electrical noise.
Operate the machine with correct voltage supply. Large voltage drops caused by an unstable power supply may
cause the overload protection circuit to function, or lower the 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:
1 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.
2 Direct current (DC) cannot be used.
[Reason] The controllers will only function with alternating current (AC).
