DD15 Operator Guide – Driving On Flat, Dry Pavement

Driving On Flat, Dry Pavement

Use the following guidelines when driving on flat, dry pavement: ‪

1. If driving on flat, dry, open stretches with a light load and greater slowing power is not required, place the progressive braking switch in the LOW position.
2. If you find you are still using the service brakes, move the switch to a higher position until you do not need to use the service brakes to slow the vehicle down.
3. If you are carrying a heavier load and road traction is good, move the progressive braking switch to the HIGH position.
4. Check your progressive braking switch often for proper position, since road conditions can change quickly. Never skip a step when operating the progressive braking switch.
   Always go from OFF to LOW, and then to a higher position.
