. ATTACHMENTS, OPTIONS HANDLING AUTOMATIC SPIN REGULATOR (ASR) TROUBLESHOOTING 6 - 16 WHEN A PROBLEM OCCURS IN THE SYSTEM This system is equipped with a self-diagnostic and displays an code on the character display of machine monitor. If any action code is displayed , move the machine to a safe place, a nd stop the machine. In addition c heck the code. For details, see"ACTION CODE (PAGE 3-155)". Please contact your Komatsu distributor for repair .
