25. Move in front of the radiator, inspect for any debris
that might be stuck in front of the radiator and
remove it. Check for any coolant leaks. Inspect all
headlamps and fog lights.
26. Before climbing ladder to first level, be sure ground
level engine shutdown switch is "ON" (if equipped
with this OPTION).
27. Climb ladder to main deck. Always use grab rails
and ladder when mounting or dismounting from
the truck. Clean ladder and hand rails of any
foreign material, such as ice, snow, oil or mud.
Always mount and dismount ladders facing the
truck. Never attempt to mount or dismount while
the truck is in motion.
28. If it is necessary to remove radiator cap when
checking coolant in radiator, shut down engine (if
running), and relieve coolant pressure SLOWLY
before removing radiator cap.
If engine has been running, allow coolant to cool,
before removing the fill cap or draining radiator.
Serious burns may result if coolant is not allowed
to cool.
29. Inspect battery box cover for looseness or dam-
age.
Check the battery terminals for corrosion.
30. Clean cab windows and mirrors; clean out cab floor
as necessary. Insure steering wheel, controls and
pedals are free of any oil, grease or mud.
31. Stow personal gear in cab so that it does not
interfere with any operation of the truck. Dirt or
trash buildup, specifically in the operator's cab,
should be cleared. Do not carry tools or supplies
in cab of truck or on the deck.
32. Adjust seat and steering wheel so that it is comfort-
able for use. Adjust mirrors, if necessary.
33. Read and understand the "Operator Controls And
Instrument Panel" discussion in this section.
Be familiar with all control locations and con-
trol functions BEFORE operating truck.

ENGINE START-UP SAFETY PRACTICES

Safety rules must be observed upon engine start-up.
1. Insure all personnel are clear of truck before start-
ing engine. Always sound the horn as a warning
before actuating any operational controls.
2. Check and insure Transmission Range Selector is
in "Neutral" before starting.
3. Do not attempt to start engine while cold weather
starting heater (if equipped) is in operation. Dam-
age to coolant heaters will result, due to lack of
circulation.
4. The key switch is a three position (Off, Run, Start)
switch. When switch is rotated one position clock-
wise, it is in the "run" position and all electrical
circuits (except "start") are activated. Rotate key
switch fully clockwise to "start" position (Trans-
mission Range Selector in "Neutral") and hold this
position until engine starts. "Start" position is
spring loaded to return to "run" when key is re-
leased.
Starting fluid is extremely volatile and flammable!
Use with extreme care.
If truck is equipped with optional Engine Starting
Aid for cold weather starting and ambient tem-
o
perature is below 50
to the "start" position and while rotating engine,
move the Engine Starting Aid switch to the "On"
position for three seconds; then release Engine
Starting Aid. If engine does not start, wait at least
fifteen seconds before repeating the procedure.
Do not crank an electric starter for more than 30
seconds. Allow two minutes for cooling before
attempting to start engine again. Severe damage
to starter motor can result from overheating.
5. The truck cannot be push started. Transmission
lube and control systems are inoperative when
engine is not running. See towing decal in Opera-
tor's Cab.
