Procedure for troubleshooting
If a phenomenon looking like a trouble occurs in the machine, select a proper troubleshooting No. according
to the following procedure, and then go to the corresponding troubleshooting section.
1.
Procedure for troubleshooting to be taken when action code is displayed on machine monitor:
If an action code is displayed on the machine monitor, display the failure code in the failure code display
mode (for the electrical system and the mechanical system) of the machine monitor (EMMS).
Carry out troubleshooting in [Display of failure code] according to the displayed failure code.
a Each failure code "flashes" when the trouble corresponding to it is detected. Even if a failure code
"lights up" when the starting switch is turned ON, the trouble corresponding to that failure code may
not have been repaired (Some troubles can be detected by simply turning the starting switch ON).
a If a failure code is recorded, be sure to perform the operation for reproducing it to see if the trouble
corresponding to it has been repaired (For the method of reproducing the failure code, see the trou-
bleshooting in [Display of code]).
2.
Procedure for troubleshooting to be taken when failure code is recorded:
If an action code is not displayed on the machine monitor, check for a failure code in the failure code dis-
play mode (for the electrical system and the mechanical system) of the machine monitor (EMMS).
If a failure code is recorded, carry out troubleshooting in [Display of code] according to that failure code.
a Each failure code "flashes" when the trouble corresponding to it is detected. Even if a failure code
"lights up" when the starting switch is turned ON, the trouble corresponding to that failure code may

bleshooting in [Display of code]).
3.
Procedure of troubleshooting to be taken when action code is not displayed and failure code is
not recorded:
If a failure code is not recorded in the machine monitor (EMMS), a trouble that the machine cannot find
out by itself may have occurred in the electrical system or hydraulic and mechanical system.
In this case, check the phenomenon looking like a trouble again and select the same phenomenon from
the table of "Phenomena looking like troubles and troubleshooting Nos.", and then carry out trouble-
shooting related to that phenomenon in the "E-mode", "H-mode", or "S-mode".
