More Driving Tips and Techniques Introduction MORE DRIVING TIPS AND TECHNIQUES This section covers additional driving tips and techniques on how to drive your Model 330 more efficiently. For further information on driving techniques, read the American Trucking Association’s (ATA) Truck Driver’s Handbook. It will give you more tips on starting, shifting, and driving your Model 330 Series vehicle. Coasting • Do not coast with the transmission in Neutral or with the clutch pedal depressed. Operating Instructions WARNING! Do not coast with the transmission in Neutral or with the clutch pedal depressed—it is a dangerous practice. Without the use of the retarding power of the drivetrain, your vehicle can reach dangerous speeds. At very high speeds you may not be able to put the transmission in any gear. At high speeds you could seriously damage your vehicle or cause an accident when you put the transmission in gear. The engine speed could exceed the maximum governed speed and cause a serious accident due to mechanical failures. Besides being illegal and dangerous, coasting is also expensive. It causes premature failure or damage to the clutch and transmission and overloads the brake system. Coasting with the transmission in Neutral also prevents proper transmission component lubrication. During coasting the transmission is driven by the rear wheels, and the countershaft gear (which lubricates the transmission components by oil splash) will only be turning at idle speed. Descending a Grade WARNING! Do not hold the brake pedal down too long or too often while going down a steep or long grade. This could cause the brakes to overheat and reduce their effectiveness. As a result, the vehicle will not slow down at the usual rate. To reduce the risk of personal injury and/or an accident, before going down a steep or long grade, reduce speed and shift the trans- – 96 – PB1318 3/01 Model 330

Operating Instructions mission into a lower gear to help control your vehicle speed. Failure to follow procedures for proper downhill operation could result in loss of vehicle control. Economical Driving Medium–duty truck engines are smaller than those in heavy– duty, Class–8 vehicles; therefore, your ability (as the driver) to affect fuel economy is limited. The following section includes recommendations for best engine performance and economy: Engine Overspeed — rpm • Operate the engine within the optimum engine rpm range and do not allow the rpm's to exceed the maximum governed speed. See Engine rpm chart. See your Engine Operation and Maintenance manual for information regarding engine rpm. • When the engine is used as a brake to control vehicle speed (e.g., while driving down a grade), do not allow the engine rpm to exceed maximum governed speed. • Under normal load and road conditions operate the engine in the lower end of the range.
