Change the Hydraulic Oil
NOTE:
•
Always use the same type and grade of hydraulic oil.
•
Hydraulic oil deteriorates faster on machines equipped with a hydraulic breaker than on machines
equipped with a bucket. See “Hydraulic Breaker Maintenance Interval” on page 5-15 for additional
information.
1. Swing the upper structure 90 degrees clockwise to position the hydraulic oil drain plug between the tracks.
2. Prepare the machine for service. See “Maintenance Safety” on page 2-9.
3. Relieve system pressure. See “Relieve Hydraulic System Pressure” on page 5-37.
4. Remove the left access panel. See “Remove/Install the Left Access Panel” on page 3-25
WARNING!
• Allow the hydraulic system to cool before servicing. Hot oil may cause burns or other
serious injury.
• The hydraulic tank may be under pressure, and hydraulic oil may be present at the filler
cover. Relieve any pressure to avoid injury.
Failure to follow these warnings could result in death or serious injury.
NOTICE!
• If the hydraulic oil is contaminated (discolored or containing debris), find and correct the
cause of the contamination before changing the hydraulic oil.
• Dispose of used hydraulic oil in accordance with all applicable environmental regulations.
Failure to do so could damage the environment.
