CONTROLS
Before starting to work, all operators should familiarize them -
selves with the location and function of the controls.
Hydraulic Hitch Jack Ball Valve
The hydraulic hitch jack ball valve prevents accidental flow
of hydraulic fluid into the hitch jack causing it to extend while
in operation thereby causing damage to the hitch jack and
the machine. The hydraulic hitch jack ball valve also keeps
pressure from dropping in the hitch jack cylinder to avoid the
hitch from settling.
IMPORTANT
Close the hydraulic hitch jack ball valve to prevent
accidental operation of this circuit. Ensure ball valve handle
is in closed position when not in use.
• Failure to close the ball valve during operation may cause
the hitch jack to extend causing damage to the hitch jack
and machine by accidental activation of the hitch jack SCV.
• Failure to close the ball valve during storage will cause
the machine to slowly settle causing the hitch to lower to
the ground.
