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