On wet pavement, gravel, and snow covered roads, the ABS may increase braking distances due to the system
responding to prevent wheel lockup. On very slippery surfaces such as sheet ice, braking distance may further
increase. Reduce vehicle speeds on all slippery surfaces, anticipate slowing or stopping ahead of time, and
avoid full-braking emergency stops. Failure to comply may result in damage to equipment or possible injury
or death to personnel. Seek medical attention in the event of an injury.
Stopping distances may increase on wet pavement, gravel, and snow covered roads due to the ABS
responding to prevent wheel lockup. On very slippery surfaces such as sheet ice, braking distance may further
increase. Reduce vehicle speeds on all slippery surfaces, anticipate slowing or stopping ahead of time, and
avoid fpanic stops. Failure to comply may result in damage to equipment and possible injury or death to
personnel. Seek medical attention in the event of an injury.
Pumping the service brake with ABS may lengthen the stopping distance which may lengthen the stopping
distance which could lead to a collision. Keep foot firmly planted on brake pedal when stopping, rather than
manually pumping the brakes.Failure to comply may result in damage to equipment and possible injury or
death to personnel. Seek medical attention in the event of an injury.
Do not use engine retarder on slippery road surfaces. Using engine retarder on wet, icy, or snow-covered
roads may result in loss of vehicle control. Failure to comply may result in damage to equipment or possible
injury or death to personnel. Seek medical attention in the event of an injury.
Never down-shift to a gear range lower than the tractor road speed on slippery pavement; the force of a
sudden increase in engine rpm through the transmission may cause the drive wheels to lose traction and result
in a loss of control of tractor and jackknifing of trailer. Failure to comply may result in damage to equipment
or possible injury or death to personnel. Seek medical attention in the event of an injury.
Ensure wheel chocks are placed in front of tires opposite the end of tractor to be raised and parking brake is
