Maintenance-Every 5000 Hours; Drain And Refill Hydraulic Tank Oil - Worldwide Construction And Forestry Division 380GLC Operator's Manual

Drain and Refill Hydraulic Tank Oil

NOTE: Change original factory fill hydraulic oil after first
5000 hours. Change every 5000 hours thereafter
if using Super EX 46HN, if using alternative oils
see Hydraulic Oil. (Section 3-1.)
NOTE: Perform this service at the 5000 hour interval when
operating in normal conditions. When operating with
an attachment, drain and refill as necessary.
CAUTION: Avoid personal injury from high
pressure fluid. High pressure release of oil
from pressurized system can cause serious
burns or penetrating injury. Relieve pressure
by pushing pressure release button (5).
IMPORTANT: Prevent damage to hydraulic
system components. DO NOT run engine
without oil in the tank.
Avoid mixing different brands or types of
oils. Oil manufacturers engineer their oils to
meet certain specifications and performance
requirements. Mixing different oil types can
degrade lubricant and machine performance.
This excavator is factory filled with Super EX
46HN extended life zinc-free hydraulic oil. Avoid
servicing this excavator with products that do
not meet this specification. If oils have been
mixed or if alternate service oils are desired,
the complete hydraulic system needs to be
totally flushed by an authorized dealer.
