OPERATING INSTRUCTIONS
Tips for Operation on Slick
Roads
WARNING!
To reduce the possibility of per-
sonal injury or property damage,
always allow 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 operate the engine brake
when driving/operating your ve-
hicle bobtail or with a loaded or
unloaded trailer on road surfaces
with poor traction (wet, icy, or snow
covered roads) or in heavy traffic.
Braking caused by the normal op-
eration of the engine brake could
cause you to lose control of the ve-
hicle resulting in an injury accident.
Failure to comply may result in
death, personal injury, equipment
or property damage.
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.
