You must use the tailgate lock cylinder (described previously) to unlock the tailgate in order to raise the tailgate or to fully
close (lock) the tailgate.
DANGER
Keep all parts of your body out from underneath the unit’s body and away from the cylinders when raising or lowering the
body. Serious injury or death will occur if the unit’s body suddenly lowers and traps a part of your body.
DANGER
Do not raise a body that has refuse while you do maintenance or service procedures. Refuse in the body can make the
unit unstable. Always unload refuse from the body before you raise it for maintenance or service procedures. Always use
the body props when you raise the body for maintenance or service procedures.
WARNING
Raising the body with the tailgate closed can damage the underride bumper. The underride bumper can hit the ground
when the tailgate is not fully raised before you raise the body. Serious injury or death may occur and also cause damage
to the unit.
Service Hoist Cylinders – When equipped, use the Service Hoist function to RAISE the body to perform service or
maintenance on the unit. When you do service or maintenance with the body raised, ALWAYS use the body props. After
completion of the service or maintenance procedures, always LOWER the body until it rests on the chassis. For
instructions, see Propping the Body of a Service Hoist Unit .
– The Cortex Controller monitors critical components and controls operation of the various functions.
When the Cortex Controller detects a fault or unsafe condition, it alerts the operator with an indicator light and/or a buzzer
alarm. During certain conditions, the Cortex Controller will not allow operation of all functions.
Hydraulic Oil Tank - The tank is the reservoir for the hydraulic oil which operates all hydraulic cylinders described above.
