A decal plate is located on the frame near the left
hoist cylinder which provides the operator or techni-
cian with the hook-up procedure for dumping a
loaded, disabled truck, by using a functional truck for
hydraulic power.
Refer to the Service manual for additional instruc-
tions for using this procedure.
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.
