DASHBOARD and CONTROL PANEL CONTROLS
Several controls are mounted in the Chassis Cab as well as at the Side Control Panel. These
controls allow the operator to engage and disengage the water pump, exhauster, hydraulic system,
and a vacuum breaker. The water pump, exhauster, hydraulic system, and vacuum breaker are
engaged and disengaged by
Electro-Pneumatic Solenoid Valves
. These solenoids are operated by
electric toggle switches. Because each manufacturer will have a different cab layout, even among
models of the same manufacturer, locations of controls & switches will vary from unit to unit.
