As a precaution, replace the air conditioning filter, add freon and washed excavator.

As a result, excavator Hitachi ZAXIS 250LCN become more productive and efficient. Lower fuel consumption, reduced duty cycle, vibration decreased. Due to repair of systems of decrease in toxicity excavator again meet with Stage IIIB.

The excavator was brought back to the granite quarry.
