Switch Panel
Clutch Cutout: When activated, it allows greater
engine acceleration and power to the hydraulics system
without power to the drive axles while the service
brake pedal is depressed.
In the “off” position, the clutch mecha-
nism of the transmission remains
engaged when applying the brakes.
In the “on” position, the clutch mecha-
nism is disengaged while applying the
brakes.
Normal brake force will hold the machine in position
while accelerating the engine to power hydraulic con-
trol functions during load placement.

switches for the following accessories used with
the cab enclosure option.

turns on or off either heating

tor’s station.
