. EXPLANATION OF COMPONENTS
QUICK COUPLER OPERATION PILOT LAMP (If equipped) This lamp (2) lights up and the buzzer sounds intermittently when the quick coupler is released. At the same time, "PIN DISCONNECT" is displayed on the bottom line of the character display. When releasing the quick coupler, press the quick coupler attachment switch to apply the lock, then operate the work equipment attachment lever. If this lamp is lighted up at any time except when the quick coupler is being released, it means that there is a problem in the quick coupler solenoid actuation circuit. Move the machine immediately to a safe place, stop the engine, then carry out inspection.
PARKING BRAKE REMINDER CAUTION LAMP If the engine is stopped and the parking brake is not applied, this parking brake reminder caution lamp (3) lights up together with the central warning lamp, and the alarm buzzer sounds intermittently to warn the operator. At the same time, "APPLY PKG BRAKE" is displayed on the bottom line of the character display, so pull the parking brake lever fully to apply the parking brake. When the parking brake is applied, the lamp goes out and the buzzer stops.
HST OIL TEMPERATURE CAUTION LAMP This lamp (4) lights up to warn the operator that the HST oil temperature has risen. During checks before starting (when the starting switch is turned to the ON position but the engine is not started), this monitor does not light up. During operation (engine running) When the HST oil temperature goes up, the HST oil temperature caution lamp and central warning lamp light up, and the alarm buzzer sounds intermittently. At the same time, "E02" is displayed on the character display and "HST OVERHEAT" is displayed on the bottom line, so stop the machine and run the engine at a mid-range speed under no load until the lamp goes out.
