f. If the truck is on level terrain, release handbrake lever (7) and slowly release clutch
pedal (10) while depressing accelerator pedal (9) far enough to prevent stalling and provide for
Tile clutch must be fully released while the truck is moving. Do not "ride" clutch
g. If the truck is headed upgrade, and forward motion is desired, or if headed downgrade,
and reverse direction is desired, maintain truck position by keeping the parking brake (7)
applied until the truck starts to move.
Shift transmission to tile next highest gear at a load speed just below the maximum
indicated on the instrument data plate (1) for each position. Shifting too soon or
too late causes undue wear on the engine, transmission, and power train.
h. When your truck approaches maximum road speed for first gear, depress the clutch pedal
(10), release the accelerator pedal (9), and move gearshift lever (6) to the appropriate successive
positions as indicated on the instruction data plate (1).
i. When the terrain becomes hilly, soft or rough, and your truck is heavily loaded, a more
efficient gear ratio can be obtained by moving the transfer shift lever (8) from HIGH to LOW.
To accomplish this, reduce the truck speed below the maximum speed for each gear, as
indicated on the instruction data plate (1). depress the clutch pedal (10), shift the transfer shift
lever (8) down to LOW, release the clutch pedal (10), and accelerate to desired speed.
The transfer may be shifted from low to the high range at any speed by depressing the clutch
pedal (10) and moving the transfer shift lever (8) up to the HIGH position. Be sure to
synchronize engine speed with the truck speed before releasing the clutch pedal.
Do not downshift a multifuel engine which is running above 1,800 rpm.
j. When your truck is unable to sustain cruising speeds at higher gear ratios, downshifting
will become necessary. To accomplish this; release the accelerator pedal (9), quickly depress the
clutch pedal (10),allow the transmission gears to slow down, increase the engine speed slightly,
move the gearshift lever (6) to the next lower gear and slowly release the clutch pedal.
Multifuel engines cannot be used to completely brake your truck. To do so will
cause the engine to overspeed. This can result in engine damage.
