ENGINE OPERATION - Operating Instructions 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 using the retarding power of the engine alone and more braking power is required, switch the two-position selector switch to the “LOW” position and activate the engine brakes by switching the “ON/OFF” switch to the “ON” position. If the vehicle’s drive wheels begin to skid or there is a fishtailing motion, switch the “ON/OFF” switch to the “OFF” position. If traction is maintained when the engine brakes are activated and more braking power is required, move the two-position selector switch to the “HI” position. Again, if the vehicle has lost traction or if there is a fishtailing motion, switch the “ON/OFF” switch to the “OFF” position.
DO NOT attempt to use the engine brakes in the “HI” position. 1 NOTE 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. 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 use any of the vehicle’s re- tarders in any situation that requires an immediate stop and/or in situations of poor traction (such as wet, icy or snow covered roads). Trying to use the retarder instead of the service brakes may cause a loss of vehicle control, which may result in an acci- dent involving 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.
