• Dispose of the hydraulic oil and filters in
accordance with all applicable environmental
regulations.
Failure to do so could result in damage to the
environment.

• Hydraulic oil deteriorates faster on machines
equipped with a hydraulic breaker than on machines
equipped with a bucket.
1. Prepare the machine for service. See “Maintenance
Safety” on page 2-5.
2. Relieve system pressure. See “Relieve Hydraulic
System Pressure” on page 5-29.

Check all hoses and lines for leaks. Replace damaged or
leaking hoses or lines immediately. Any hydraulic pump
lines or connectors connected to the engine
compartment must be replaced if damaged.
Make sure all hydraulic lines and hoses do not come in
contact with each other or with high-temperature engine
components.
