PRELIMINARY POINTERS
Proper operation of this vehicle for the first few hundred .
miles will contribute greatly to longer life and add much to its
future performance and economy of operation.
If not properly maintained and wisely operated, your truck
can lose much of its efficiency and performance which it is
capable of supplying.
The following are maintenance hints and driving tips to aid
you in realizing the maximum in efficiency and economy from
your Chevrolet truck:
• It is recommended that the maximum speed be confined to
50 miles per hour for the first 500 miles.
• Use the lowest gear ratio available when starting up with
heavy loads and climbing grades to avoid "over-taxing"
the engine.
• Avoid driving for extended periods at anyone constant
speed, either slow or fast.
• Avoid full throttle starts and severe application of the brakes
in stopping.
• Continuous driving at high speeds should not be done until
the truck has been driven 2000 miles.
• Drive at reasonable lower speeds until engine has warmed up.
• Hill and mountain driving requires more gasoline. A carbu-
retor adjusted for sea level driving becomes extremely
wasteful at 5000 feet or more altitude.
• The engine should be regularly "tuned-up" so that power
robbing conditions, which may develop so graduaHy that
they are not noticed, may be found and corrected. Faulty
spark plugs, for instance, can waste as much as 'one gallon
of gasoline in every ten.
• Use only highest quality fuel. Poor quality gasoline, whether
Regular or Premium, may introduce harmful deposits into
the engine.
• Use a good grade of proper viscosity engine oil. Too heavy
an oil wastes gasoline.
• Have the air cleaner cleaned and reoiled, or replaced ac-
cording- to recommendation. A dirty air cleaner can reduce
mileage by as much as 10 per cent.
• The front wheel and tire assemblies should be balanced
periodically to provide a more comfortable ride and prevent
improper tire wear.
Such care in operating your new truck will assure proper
mating-in of all the running surfaces of the moving parts of the
engine, transmission and rear axle . .

INSTRUMENTS AND CONTROLS
The type, location and operation of instruments and controls
vary on different models and different series trucks. There-
fore, regardless of past experience an owner or driver may
have had, it is advisable to familiarize yourself with the
instruments and controls and their use before driving this
new truck. As several different instrument groups and dash
panel assemblies are used, the paragraph concerning each
item will describe the operation or use of that item and will
not attempt to describe location. The location of all instru-
ments and controls will be shown in various illustrations on
the following pages.
STANDARD INSTRUMENTS
GASOLINE GAUGE
The electrically operated gasoline gauge is wired through
the ignition switch and will only indicate the amount of fuel
in the tank when the ignition switch is turned on. As this
gauge utilizes a "balanced needle" for greater accuracy, the
gauge needle will not necessarily return to the empty position
with the ignition switch off. The needle may stop in the center
of the gauge or go off at either end when the ignition switch is
turned off.
TEMPERATURE GAUGE
The water temperature gauge may register anywhere in the
band between the two marks ("e" and "H") and still indi-
cate normal operating temperatures. Hot weather, long hard
driving, or P'i"olonged idling may cause the needle to be in the
high range of the gauge. However, if the needle moves clear
to the " H" hot end of the gauge, stop the engine until the
cause of overheating is determined. As this gauge utilizes a
"balanced needle" for greater accuracy, the gauge needle will
not necessarily return to the empty position when ignition is
turned off. The needle may stay in the center of the gauge or
go off at either end when the ignition switch is turned off.
NOTE: Do not remove the radiator cap when
engine is excessively hot, do not put water
in an overheated engine, and , do not run en-
gine when indicator is above "H" .

TACHOMETER
USED)

A~ETER OR GENERATOR
TEL-TALE LIGHT
One of these two units will be used in this vehicle. The
lighter trucks use a generator tel-tale light while the heavier
series use the ammeter .
The ammeter indicates the flow of current to and from the
battery, except for the current taken by the starting motor.
The generator tel-tale light indicates generator operation.
Should the ammeter show discharge, or the tel-tale light
remain on when the truck is being driven at medium speed,
trouble is indicated in the charging system and the battery
will soon become discharged. Under most driving conditions
the tel-tale light should remain off or the ammeter should show
some charging rate . The charging rate shown on an ammeter
with a fully charged battery may be so slight that the needle
may appear to remain centered on the gauge and not move
away from the gauge center mark.
NOTE: With the engine idling, and the battery
charged, the ammeter may show slight dis-
charge or the tel-tale light may "flicker" or
remain on.
OIL PRESSURE GAUGE OR INDICATOR
This vehicle will be equipped with one of these two units.
The oil pressure gauge is used in the heavier series trucks
while the oil pressure indicator (warning light) will be used in
the light trucks.
Both of these units indicate whether or not the oil pump is
operating, but do not indicate the amount of oil in the crank-
case . In addition, the oil pressure gauge gives an indication of
oil
pressure in the lubrication system.
A low gauge reading is normal at idling speeds with a warm
engine and light body oil; however, as the engine speed is
increased, the hand on the gauge should register near the
center of the gauge, or the indicator light should go out. In
cold weather (especially with heavy body oil) the hand (only
on vehicles so equipped) may move over to the "60" mark
at comparatively low engine speeds. If so, run the engine just
above idling speed until the hand drops to around the center
of the gauge before driving the vehicle .
NOTE: If gauge does not show any pressure
or indicator light stays on, stop the engine im-
mediately and determine the cause.

Fig. 5~lnstruments and Controls-Flat Face Cowl Models (Typicall
This tel-tale light, and all other tel-tale lights used, will light
while engine is being started. This is done so that bulb opera-
tion can be checked.
SPEEDOMETER
The speedometer hand moves across the dial indicating the
speed of the vehicle in miles-per-hour.
Odollleter
The group of six figures in the speedometer lower center
section indicate the total mileage the truck has been driven.
HEADLIGHT BEAM INDICATOR
A red indicator light is wired into the dimmer switch so
that when the headlights are on upper bearn, the indicator
light will be on .
·8·

OVERSPEED WARNING LIGHT
As standard equipment on several larger series trucks and
optional equipment on certain others, a red light warns of ex-
cessive engine speed on overrun on V8 engines . As a check to
be certain that the bulb works, this light is so wired that it
turns on at the instant the ignition switch is turned on and
goes off after the engine has started .
OPTIONAL INSTRUMENTS
AIR PRESSURE GAUGE
This gauge is used to indicate the air pressure in the full air
brake system or the air over hydraulic system . Do not attempt
to operate the vehicle unless pressure has built up to 60 psi or
more.
Low Pressure Indicator
A warning buzzer, mounted under the dash operates when
air pressure in the brake system falls below 60 psi. When first
starting the vehicle, the warning buzzer will sound until pres-
sure has built up. When the desired pressure has been reached,
the buzzer will shut off. If the buzzer operates under normal
driving , bring the vehicle to a controlled stop and locate and
correct trouble before proceeding.
NOTE: Do not operate vehicle while buzzer is
operating as brakes are not in proper operat-
ing condition.
TACHOMETER
The tachometer (when installed) indicates engine speed in
revolutions per minute. The scale reads 10, 20, 30, etc. By add-
ing two zeroes after . the reading , the indicated engine speed
will become 1000, 2000, 3000, etc .
VACUUM GAUGE
This gauge, when installed, indicates engine vacuum. Proper
int e rpretation of the gauge readings will indicate engin e con-
dition, and in many instances show the way to more economi-
cal operation. .
