Operating Instructions Operating the Transmission
Model 330 PB1318 3/01
– 65 –
1. Put the transmission in Neutral.
2. Release the clutch pedal and let the transmission oper-
ate in Neutral for three to five minutes prior to shifting into
either a forward or reverse range.
Putting the Vehicle in Motion
After making sure the vehicle’s oil and air pressure are cor-
rect and all other parts and systems are in proper working
condition:
1. If your truck is equipped with a hand throttle, disengage
the hand throttle before driving the vehicle.
2. Fully depress the clutch pedal until the clutch brake
makes contact (see
page 66
). The contact will occur at
about 1 inch or less from the floorboard.
• The total stroke of the clutch pedal is about 10
inches. The first 1½ inches is free travel. After the
free travel comes the release stroke, which is the
part that fully releases the clutch. The last inch
engages the clutch brake.
• Always start out in a low gear. Starting in a higher
gear, even with a light load, will cause a very jumpy
start and excessive wear.
CAUTION: Always use first gear or a low speed
range to start the vehicle in motion. The use of a
higher gear or speed range forces undue strain
on the engine, clutch, other transmission com-
ponents, and may cause damage.
3. Evaluate the road surface conditions and terrain your
vehicle is on. Select a gear low enough to let your vehicle
start forward with the throttle at idle.
4. Push the parking brake valve handle (Yellow) against the
dash panel to release the brakes.
5. Release the clutch pedal, then gradually accelerate to
permit smooth starting,
6. Do not allow your vehicle to roll (even a little) in the oppo-
site direction during clutch engagement. If you need to
start up on an incline, apply your service brakes before
you release the parking brake. Then release your service
brakes as you engage the clutch and apply throttle.
