CAUTION
The truck instruction and caution data plates (1), (2), (3), and (4) on the
instrument panel, give the maximum speeds in mph at which the truck may be
safely operated in various transmission gear ratios with the transfer (8) in either
HIGH or LOW range (3). Do not exceed these specified speeds. Shift the
transmission to the next higher gear when the truck speed approaches the
maximum road speed of the gear being used.
Do not allow engine speed in any gear to exceed 2,800 rpm for gasoline; 2,600 rpm
for multifuel; and 2,100 for diesel, as shown by red arrow on tachometer (5).
Multifuel and diesel trucks must be operated within the following rpm limits:
rpm at which engine should be operated under load
A= Lowest
C= Recommended rpm range for cruising
D= Highest operating rpm when under load in any gear .
e. Place transmission gearshift lever (6) in
1 (first) or R (reverse) position (depending
on desired direction of travel).
CAUTION
When making hard right or hard left turns (against the turning stops), avoid
maintaining these positions for longer than 5 seconds to prevent excessive heat
buildup in the hydraulic steering system.
NOTE
It is mandatory to use first (low) gear to place the truck in forward motion under
all conditions.
