Completely drain the receiver/separator system including the piping
and oil cooler by removing the drain plug(s) and collecting the used oil
in a suitable container.
Replace the drain plug(s) ensuring that each one is secure.
RUNNING GEAR WHEEL BEARINGS
Wheel bearings should be packed with grease every 6 months. The
type of grease used should conform to specification MIL-G-10924.
NOTE: If the oil is drained immediately after the machine has been
running, then most of the sediment will be in suspension and will
therefore drain more readily.
CAUTION: Some oil mixtures are incompatible and result in the
formation of varnishes, shellacs or lacquers which may be insoluble.
NOTE: Always specify PRO-TEC oil for use at all ambient
temperatures above -23°C.
