2-8. Placing the Truck in Motion.
Allowing the engine to run with the transmission engaged and the transfer in
NEUTRAL may cause transfer bearing failures. Always shift the transmission to
NEUTRAL when the engine is running while the truck is stationary.
On trucks equipped with a transfer power takeoff, the transfer can be operated in
NEUTRAL as long as the power takeoff is engaged. The transfer bearings receive
lubrication from the power takeoff pump. Never disengage the power takeoff when
the transfer is in NEUTRAL, because this will disengage the power takeoff pump
which supplies lubrication for the bearings.
Make sure that the front winch, auxiliary equipment, and tools are locked and
stowed for travel.
Set the vehicle light switches for lighting as required (see lighting chart, page
c. Check to be sure that the front winch
control lever (1) is in neutral and secured
with hinge lock.
d. Depress clutch pedal (3) and shift
transfer shift lever (2) to LOW or HIGH
operating range, depending on the expected
terrain, load and vehicle speed.
The purpose and use of the transmission and transfer must be understood by the
driver before any attempt is made to operate the truck. The truck cannot be moved
until the transfer shift lever (2) is in the HIGH (up) or LOW (down) position.
Transmission gearshift lever positions do not in any way affect the selection of the
transfer range (LOW or HIGH) to be used. The transfer LOW range provides greater
power and lower speed in the five transmission speeds to suit heavy loads or
difficult terrain conditions. The HIGH range provides greater speed at lower power
in the five transmission speeds under normal load and road conditions.
