Page 2-22 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 fil-
ters.
A CAUTION decal is attached below the hydraulic
tank oil level sight gauge. Check level with body
down, engine stopped, and key switch "Off". 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, escap-
ing 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 medical treatment by a physician familiar
with this injury is not received immediately.
A warning plate is located above the hydraulic sys-
tem (APU) quick disconnect fittings in front of the
hydraulic tank which provides instructions to the
operator or technician for towing a disabled truck.
This plate specifies the requirements for an auxiliary
source of supply for hydraulic oil and the proper
hookup.
TEST BOTH STEERING AND BRAKE SYSTEM
OPERATION BEFORE TOWING.
