4. The keyswitch 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.
a. Turn keyswitch to “Run” (not “Start”) position.
b. With Selector Switch in “Neutral”, rotate
keyswitch fully clockwise to “Start” position,
and HOLD this position until engine starts (see
NOTE below). “Start” position is spring-loaded
to return to “Run” when key is released.
c. After engine has started, place REST switch in
“Off” position (de-activate the “REST” mode of
operation).
Refer to discussion of REST SWITCH, in Sec-
tion N, Cab, “Instrument Panel & Indicator
Switches”.
NOTE: This truck is equipped with an engine prelube
system. With this feature, a noticeable time delay may
occur (while engine lube oil passages are being filled
and pressurized) before engine cranking will begin.
Cold Weather Starting
••••
Do not crank an electric starter for more than
30 seconds.
••••
Allow two minutes for cooling before attempt-
ing to start engine again.
Severe damage to starter motor can result
from overheating.
AFTER ENGINE HAS STARTED
1. Become thoroughly familiar with steering and
emergency controls. After engine has started and
low pressure and warning systems are normal,
test the truck steering in extreme right and left
directions. If the steering system is not operating
properly, shut engine down immediately. Deter-
mine the steering system problem and have re-
pairs made before resuming operation.
2. Operate each of the truck’s brake circuits at least
twice prior to operating and moving the truck.
These circuits include individual activation from
the operator’s cab of the service brake, parking
brake, and brake lock. With the engine running
and with the hydraulic circuit fully charged, acti-
vate each circuit individually. If any application or
release of any brake circuit appears sluggish or
improper, or if warning alarms are activated on
application or release, shut the engine down and
notify maintenance personnel. Do not operate
truck until brake circuit in question is fully opera-
tional.
3. Check gauges, warning lights and instruments
before moving the truck to insure proper system
operation and proper instrument functioning.
Give special attention to braking and steering
circuit hydraulic warning lights. If warning lights
come on, shut down the engine immediately and
determine the cause.
4. Insure headlights, worklights and taillights are in
proper working order. Good visibility may prevent
an accident. Check operation of windshield wiper.
5. When truck body is in dump position, do not allow
anyone beneath it unless body-up retaining pin or
cable is in place.
6. Do not use the fire extinguisher for any purpose
other than putting out a fire! If extinguisher is
discharged, report the occurrence so the used
unit can be refilled or replaced.
7. Do not allow unauthorized personnel to ride in the
truck. Do not allow anyone to ride on the ladder
of the truck.
8. Do not leave truck unattended while engine is
running. Shut down engine and apply park brake
before getting out of cab.
