CONTROLS
CARBURETOR CHOKE
The choke is used to enrich the fuel mixture by
restricting the air flow to the carburetor. The distance the
choke control is pulled out regulates the fuel-air mixture and
increases the engine speed to a fast idle to prevent stalling
during the engine warm-up period. Push the choke in when
the engine is warmed up.
CARBURETOR THROTTLE
The throttle control may be used to open the throttle
slightly when starting the engine or to set the throttle at any
position to maintain a constant engine speed.

Push the lighter knob in all the way. The lighter will
automatically return to the normal position when hot.

FUEL GAUGE SWITCH
(Vehicles Equipped with Auxiliary Fuel Tanks)
The fuel gauge switch should be positioned
to indicate the tank (left, right or forward rear) from which fuel
is being used. The fuel gauge will only indicate the level of
the fuel in the tank being used.
FUEL PRIMER SWITCH (DIESEL ENGINE)
This truck is equipped with an electric in-tank
mounted fuel pump. In addition, an electric fuel system
primer switch is located on the instrument panel.
HEADLIGHT BEAM SELECTOR
The beam selector permits the driver to lower the
headlight beam when approaching or passing vehicles, and to
raise the headlight beam for open highway use or whenever
necessary. A light located in the instrument cluster glows
when the headlights are on "upper" beam. See gauges and
instruments for location of indicator light.
HEATER-AIR CONDITIONER
IMPORTANT
The air conditioning system incorporates a
low pressure switch which disengages the
compressor clutch if evaporator outlet falls
below a certain level. To restart the air
conditioning system after an automatic shut-
down has occurred, the operator must do one
of the following:
1.
Place "A/C" lever in "OFF" position
and then back "ON".
2.
Place blower switch in "OFF" position
and then back "ON".
If
system
continues
to
shut
down
automatically, it will be necessary to have the
system checked for the cause of low pressure.
