Warnings and Cautions
A plate on the side of the hydraulic tank furnishes
instructions for filling the hydraulic tank.
Keep the system open to the atmosphere only as long
as absolutely necessary to lessen chances of system
contamination. Service the tank with clean Type C-4
hydraulic oil. All oil being put into the hydraulic tank
should be filtered through 3 micron filters.
A CAUTION decal is attached below the hydraulic tank
oil level sight gauge. Check level with body down,
engine stopped, and key switch ''Off'' (to assure pres-
sure has been relieved from system) before removing
fillercap.
Add oil per filling instructions, if oil level is below top of
sight glass.
A warning plate is attached to the frame above the
hydraulic system (APU) quick disconnect fittings to
alert technicians that high pressure hydraulic oil is
present during operation. Care must be taken when it
is necessary to open the hydraulic system. There is
always a chance of residual pressure being present.
Open fittings slowly to allow any pressure to bleed off
before removing any connections.
Any operating fluid, such as hydraulic oil, escaping
under pressure can have sufficient force to enter a
person's body by penetrating the skin. Serious
injury and possibly death may result if proper medi-
cal treatment by a physician familiar with this injury
is not received immediately.
