Override/Fault Reset Switch
Switch (3, Figure 5-
4) is spring-loaded
to the OFF position.
When pushed in
and held, this
switch may be used
for several functions.
1. This switch permits the operator to override the
body-up limit switch and move the truck forward
when the directional control lever is in FOR-
WARD, the dump body is raised, and the
brakes are released.
Use of the override switch for this purpose is
intended for emergency situations only!
2. The push button deactivates the retard pedal
function when speed of truck is below 4.8 kph (3
mph).
3. The override switch is also used to reset an
electric system fault when indicated by a red
warning light. Refer to Overhead Status/Warn-
ing Indicators in this section.
Engine Stop Switch
Switch (4, Figure 5-4) is used to stop the
engine. Pull the switch up to stop the
engine. Push the switch back down to
enable engine operation.
Use this switch to stop the engine if the key switch
should fail to operate, or to stop the engine without
turning off the 24 VDC electrical circuits.
A ground level engine stop switch is also located at
the right front corner of the truck.

hoist cylinders begin to extend and then let the
engine go to low idle as the last stage reaches
half-extension.

full extension.
5. After material being dumped clears the body,
lower the body to frame.
Refer to Operating Instructions - Dumping, for more
complete details concerning this control
