A three-speed fan switch controls the flow of air to any
selected air vents.
The center air panel vents, located on each side of the
heater control panel, allow unheated forced air to be
directed vertically and horizontally and can be opened
or closed independently by means of a built-in damper.
See Fig. 3.23.
The side panel vents allow heated forced air to be di-
rected vertically and horizontally.
The roof vent (see Fig. 3.24) can be adjusted to five
different positions but is not removable. To adjust, hold
the lateral bars and incline the ventilator forward, back-
ward, or to either side. To open completely, push the
ventilator upward.
The foot-level vents, located on each side of the front
cab wall under the instrument panel, are opened or
closed by moving the actuator lever on the vent. See
Fig. 3.25.
