WARNING SUMMARY - CONTINUED
WARNING DESCRIPTIONS - CONTINUED
Never allow vehicle to coast in neutral (N) position. Engine braking action is not
available when transmission is out of gear, and damage to equipment and possible
injury or death to personnel may result. Seek medical attention in the event of an
injury.
Center of gravity is higher on vehicles equipped with Crew Protection Kit. Always use
slower speeds when driving vehicle. DO NOT operate vehicle on steep hills or inclines.
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.
Visibility is reduced on vehicles equipped with Crew Protection Kit. Always use a
ground guide when maneuvering vehicle near obstacles. 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.
Vehicles equipped with Crew Protection Kit have different door handles and latching
hardware. Exercise caution when opening and closing armor doors to not allow
clothing or equipment to catch on door hardware. Failure to comply may result in
injury to personnel. Seek medical attention in the event of an injury.
DO NOT park vehicles equipped with Crew Protection Kit on a hill or incline. The
parking brake may have insufficient braking capacity to hold vehicle due to increased
vehicle weight. 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 and injury or death to personnel. Seek medical attention
in the event of an injury.
Failure to comply to downhill driving procedures may cause loss of vehicle control and
result in injury or death to personnel. Seek medical attention in the event of an injury.
Excessive use of the service brake to control downhill speed will result in loss of
braking power due to heat build up. Failure to comply may result in severe injury or
death to personnel. Seek medical attention in the event of an injury.
The engine brake loses its effectiveness to control speed of tractor when tractor is
pushed by additional weight of trailer on downhill grades. Failure to downshift
transmission to lower gear range and use service brakes to keep tractor and engine
speeds under control may result in damage to equipment and possible injury or death to
personnel. Seek medical attention in the event of an injury.
Never downshift to a gear range lower than the tractor road speed on slippery
pavement. Sudden increase in engine rpm may cause drive wheels to lose traction with
pavement and result in loss of control of tractor or jackknifing of trailer. Failure to
comply may result in damage to equipment and injury or death to personnel. Seek
medical attention in the event of an injury.
Do not use the pusher axle as a step when in the raised position. When pusher axle
wheels are off the ground, it freewheels. Failure to comply may result in injury to
personnel. Seek medical attention in the event of an injury.
