• Pressure may be generated inside the traveling devices. Slowly loosen the plug to release the internal pressure.
Replace the oil after 500 hours of operation has been reached for the first time.
• Check the drain oil, and if metal chips or powder is found in the oil, contact your KOBELCO authorized dealer.
• Dispose of the drain waste oil properly as industrial waste.
