Check the hydraulic oil level in the sight glass for the hydraulic tank.
Look for air bubbles in the oil. Look for water in the oil.Note: Air bubbles may be caused by a fitting that is loose or damaged. A loose fitting or a damaged fitting allows air to enter the suction side of the system. This causes the oil to leak.
Add oil to the hydraulic system, if necessary. Refer to the Operation and Maintenance Manual for the recommended oil and for the correct procedure.
Check all lines, all hoses, and all connections for damage and for leaks. Look for fluid on the ground under the machine.Note: If fluid can leak out of a fitting or out of a connection, air can leak into the system.
