WARNING
DO NOT use the vehicle’s engine
compression brake or exhaust brake in
any situation that requires an immedi-
ate stop and/or in situations of poor
traction (such as wet, icy, or snow cov-
ered roads). Trying to use the engine
compression brake or exhaust brake
instead of the service brakes may
cause a loss of vehicle control, which
may result in an accident involving
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 braking
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 compression brake or exhaust
brake. If traction is maintained using the
braking power of the engine alone and
more braking power is required, switch the
two-position selector switch to the “LOW”
position and activate the engine
compression brake or exhaust brake by
switching the “ON/OFF” switch to the “ON”
position. If the vehicle’s drive wheels begin
to skid or there is a fishtailing motion,
switch the “ON/OFF” switch to the “OFF”
position. If traction is maintained when the
engine compression brake or exhaust
brake is activated and more braking power
is required, move the two-position selector
switch to the “HI” position. Again, if the
vehicle has lost traction or if there is a
fishtailing motion, switch the “ON/OFF”
switch to the “OFF” position. DO NOT
attempt to use the engine compression
brake or exhaust brake in the “HI” position.
