require that special considerations be given to engine starting.
The following chart suggests these options: -
Note: At temperatures below 0°C [32°F], operate the engine at
moderate speeds for 5 minutes before full loads are applied.
To activate the block heater, install the heater cord into a 110
volt AC. (6.5 Amp.) outlet.
A
Engine Warm-Up
Avoid full throttle operation when the engine Is cold. When
starting a cold engine, bring the engine up to operating speed
slowly to allow the oil pressure to stabilize as the engine warms
up.
If temperatures are below 0°C [32°F], operate the engine at
moderate speeds for 5 minutes before full toads are applied.
Hand Throttle
To operate the engine at a moderate speed, the manual
transmission trucks have been equipped with a hand throttle.
With the engine running, depress the throttle foot pedal to
approximately 1 /4 throttle. Turn the hand throttle handle
counter clockwise to unlock.
Siowly pull the handle out until you feel resistance. Hold the
handle while lifting your foot from the throttle pedal. If the
engine speed stays constant, turn the handle clockwise to lock
the throttle at this warm-up speed.
Caution: Do not operate the truck with the hand throttle
activated.
