NOTE
Samples of hydraulic oil should be drawn
from the reservoir and tested annually.
These samples should be taken when the
oil is warmed through normal operation
of the system. The sample should be
analyzed by a qualied lubrication
specialist to determine if it is suitable for
continued use. Oil change intervals will
depend on the care used in keeping the
oil clean, and the operating conditions.
Dirt and/or moisture contamination will
dictate that the oil should be changed
more often. Under normal use and
operating conditions, the hydraulic oil
should be changed every two years.
