1.
When operating off-highway, or under adverse
conditions, always use low gear (if so equipped)
when starting to move the vehicle.
When operating on-highway, with no load, or
under ideal conditions, use 1st gear when start-
ing to move the vehicle.
For all conditions, use the highest gear that is
still low enough to start the vehicle moving with
engine idling, and without slipping the clutch ex-
cessively.
2.
Use the clutch brake to stop gear rotation when
shifting into 1st or reverse when the vehicle is
stationary. The clutch brake is actuated by de-
pressing the clutch pedal all the way to the floor.
For normal upshifts and downshifts, only a partial
disengagement of the clutch is necessary to
break engine torque.
3.
Do not make range shifts with the vehicle moving
in reverse gear.
4.
The shift lever should not be moved to the center
or left rail positions at vehicle speeds above 40
mph (65 km/h).
5.
Double-clutch between all upshifts and down-
shifts.
6.
After your shifting ability improves, you may want
to skip some of the ratios. This may be done
only when operating conditions permit, depend-
ing on the load, grade, and road speed.
7.
Avoid hunting for neutral by moving the gear shift
lever from the left rail to right rail. This action can
cause excessive transmission wear.
Upshifting
1.
Position the gear shift lever in neutral. Start the
engine, and bring the air system pressure up to
100 to 120 psi (689 to 827 kPa).
2.
Depress the clutch pedal to the floor. Shift into
1st gear, then engage the clutch, with the engine
at or near idle speed, to start the vehicle moving.
3.
Button-only shift—Preselect the next gear by
sliding the shift button forward. Break torque by
releasing the throttle or by depressing the clutch
pedal. Decrease engine speed to synchronize
the engine speed with the transmission speed.
The shift will complete when the engine rpm has
decreased to the proper speed.
The button-only shift is used for gear changes
from 1st to 2nd, 3rd to 4th, 5th to 6th, 7th to 8th,
and 9th to 10th.
4.
Lever-only shift—Break torque by releasing the
throttle and depressing the clutch pedal. Double-
clutching, move the shift lever to the next desired
gear position. Decrease engine speed to syn-
chronize the engine speed with the transmission
speed. The shift will complete when the engine
rpm has decreased to the proper speed.
The lever-only shift is used to skip a full gear.
