ENGINE OPERATION - Operating Instructions 1 Shift to a Lower Gear on Grade The operation of any vehicle is difficult to predict on slick roads. The first 10 to 15 minutes of rainfall are the most dangerous, as road dirt and oil mixed with rain create a very slippery surface. WARNING Do not drive with frequent or continu- ous use of the service brakes. This can overheat the brakes and result in excessive lining wear, increased stop- ping distances, possibly an accident and may lead to personal injury. Be- fore descending a steep grade, shift to a lower gear, keep the vehicle speed low, and avoid continuous application to the brakes.
Failure to comply may result in death, personal injury, equip- ment or property damage. WARNING Do not use any of the vehicle’s retard- ers in any situation that requires an im- mediate stop and/or in situations of poor traction (such as wet, icy or snow covered roads). Trying to use the re- tarder instead of the service brakes may cause a loss of vehicle control, which may result in an accident involv- ing death or personal injury. If frequent use of the vehicle service brakes is required, it is recommended that a slower control speed be used by selecting a lower transmission gear.
NOTE Tips for Operation on Slick Roads When driving on slick roads, start with the “ON/OFF” switch in the “OFF” position and the two-position selector switch in the “LOW” position. If your tractor is equipped with a twin-screw rear axle, position the power divider switch in the “unlocked” position. Remove your foot from the accelerator pedal to make sure the vehicle will maintain traction with the retarding power of the engine alone. If the vehicle drive wheels begin to skid or if there is a fishtailing motion, DO NOT activate the engine brakes. If traction is maintained The longer or steeper the hill, the more important it is to use your engine brakes.
Make maximum use of your engine brakes by gearing down and letting the engine brakes do the work. WARNING To reduce the possibility of personal injury or property damage, always al- low for extra distance between your vehicle and other objects when using the service brakes or engine brakes on slick roads. 26 Y53-1166-1G1 (08/2018) 304050 1 3 5 20 60 10 70 2 4 R 0 MPH 80 2 1 0 0 OK RPM 304050 1 3 5 20 60 10 70 0 MPH 80 2 4 R 2 1 0 0 OK RPM
