SERIES 50 OPERATOR'S GUIDE
Driving on Wet or Slippery
Pavement
Do not attempt to use the engine brake
system on wet or slippery roads until
you have some experience with it on
dry pavement.
To avoid injury from loss of
vehicle control, do not activate
the Engine Brake system under
the following conditions:
On wet or slippery pavement,
unless the vehicle is equipped
with ABS (anti-lock braking
system) and you have had
prior experience driving
under these conditions.
When driving without a trailer
(bobtailing) or pulling and
empty trailer.
If the tractor drive wheels
begin to lock or there is
fishtail motion after the
Engine Brake is activated.
Deactivate the brake system
immediately, if this occurs.
Failure to observe these
precautions may result in
loss of vehicle control and/or
personal injury.
NOTE:
On single trailers or combinations,
a light air application of the trailer
brakes may be desirable to help
keep the trailer stretched out. Follow
the manufacturer's recommended
operating procedure when using your
trailer brakes.
On wet or slippery pavement, start
with the master switch in the OFF
position and use the gear you would
normally use under these conditions.
If the vehicle is maintaining traction,
place the selective braking switch in
the LOW position and turn ON the
engine brake system. If the drive
wheels are maintaining traction and
you desire greater slowing power,
move the braking switch to the next
highest position.
However, if the tractor drive wheels
begin to lock or there is a fishtail
motion, turn the engine brake system
OFF immediately and do not activate
it until road conditions improve.
Check your progressive braking
switch often for proper position, since
road conditions can change quickly.
Never skip a step when operating the
progressive braking system. Always
go from OFF to LOWand then to a
higher position
