12 EXCAVATOR OPERATION EXCAVATOR OPERATION CONTROL OBSERVATIONS DURING OPERATION Battery Charge If the battery is not charged by the generator, the alarm lamp will light up. Should this occur during operation, check the electrical system or contact your KUBOTA dealer. (see "TROUBLESHOOTING") B Stop the Engine immediately if: A Sudden increase or decrease in engine revolution occurs. A Sudden abnormal noises occur. A Exhaust gases turn suddenly very dark. RUNNING-IN OF THE NEW EXCAVATOR The operation and care of the new excavator influences its life span. Your new excavator has been carefully checked and tested before leaving the factory.
In spite of this, all movable components must run-in during the first 50 work hours. Do not work with full revolution and full loads during this period. It is most important to run-in your excavator properly in order to achieve its full performance and longevity. During the running-in, the following points should be adhered to in all cases. Make following control observations during operation to be sure that everything functions normally. B Alarm Lamps Should an alarm lamp light up during operation, stop the engine immediately and as described below, check for the cause. Do not use the excavator when an alarm lamp is lit up.
Explanation of alarm lamp is described as "Malfunction Indicator (Quick Diagnosis)" under "STARTING THE ENGINE" in "OPERATION OF THE ENGINE". B Do not Work with Full Revolutions or Full Loads during the First 50 Working Hours. A Let the engine warm up sufficiently in the cold season. A Do not let the engine rev-up more than necessary. B Oil Change in the Run-in Stage. The lubrication oil plays a specially important role during the run-in phase of the excavator. The numerous movable parts are not yet run-in, so that many fine metal particles can develop and cause damage or shorten the lifetime of many components.
Pay attention to the oil- change intervals and execute them sooner rather than later as necessary. See the subject "Care and Maintenance" for more details on the oil-change intervals. Engine Oil Pressure When the engine oil pressure sinks below the prescribed level, the alarm lamp will light up. Should this occur during operation and not go out even if the engine revolution is increased by 1000 rpm, check the engine oil level. (see "Check Engine Oil Level" under "DAILY CHECKS" in "MAINTENANCE").
