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.
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.

If frequent use of the vehicle service

a slower control speed be used by
selecting a lower transmission gear.
Tips for Operation on Slick Roads
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.
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 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.
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
