Set your trailer brakes and inspect the slack adjusters. If they are
not adjusted properly, repeat the procedure and inspect again. If still not
adjusted properly, call Fleet Services and follow their instructions.
Trailer Brake Adjustment

Never tamper with or use a wrench on the slack adjuster!
After your initial vehicle inspection, get in your truck and with the
parking brake set, start the engine. Let the air pressure build up until the
governor cuts off. Release the trailer brake, charging the system with air
pressure. At this time, apply 60 to 70 pounds of application pressure to
the trailer brakes five or six times (not rapidly) or until the governor kicks
back into operation.
Set your tractor brakes and inspect your trailer slack adjusters again.
If they are not adjusted properly, repeat the procedure again and inspect
again. If they are still not adjusted properly, call Fleet Services and follow
their instructions.
Driving the Autoshift

Proper Start-Up:
1. Make sure the shifter is in neutral “N” and the parking brake is
set.
2. Depress the clutch pedal and turn the ignition key to “On.” Wait
for the service light on the shifter to go out and for a solid “N” to
appear on the gear display.
3. Start the engine and let out the clutch pedal to register proper
input speed. If the Auto Shift does not see input speed, it will not
shift into initial starting gear.
4. Wait for air pressure to build to 90 psi.

Selecting a Starting Gear:
1. Select “D”, “H” or “L”.
2. Depress the clutch pedal. A solid number on the gear display
indicates that the gear is fully engaged. If flashing down arrows
appear on the gear display, this indicates that the input shaft has
not slowed down enough to get into gear. Continue to depress the
clutch pedal until the down arrows are off. If the down arrows
are off and the gear number continues to flash slowly, let up on
the clutch pedal to fully engage the gear.
