Operation
Push the rocker switch up to turn
the exhaust brake on. The switch
will illuminate in the ON position.
Push the switch down to turn the
brake off.
Starting engine
Before starting the engine, make sure that the exhaust brake switch is in
the OFF position. Do not turn the exhaust brake on until the engine has
reached normal operating temperatures.
Driving downhill
While approaching a steep grade, make sure that the exhaust brake
switch is in the ON position. The exhaust brake actuates as soon as you
remove your foot from the accelerator pedal. While going down the
grade, use a low enough gear to descend safely with a minimum
application of the service brakes. As a general guideline, use the same
gear as you would to ascend the hill.
Before descending a hill or steep grade always select the proper gear. If
the transmission is taken out of gear while descending it is possible that
you will not be able to select another gear because of maximum RPM
being governed.
Make sure the engine speed does not exceed the maximum allowable
engine RPM. Exceeding the maximum allowable engine RPM will result
in damage to the engine. Apply the service brakes to reduce the engine
RPM or make a slower descent by using a lower gear.
The exhaust brake is not recommended for use on slippery or
low traction road surfaces. Under these conditions a loss of
vehicle control could possibly occur.

When split shifting, the axle shift control must stay UP in the
HIGH range until after any transmission lever movement.
A 2±speed axle should NEVER be shifted on a downgrade.
To downshift the axle from HIGH to LOW range, either the ring gear has
to speed up by one-third, or the wheels have to slow down by one-third
to allow for synchronization. When you are on a down grade, the wheels
will not slow down, but will tend to speed up. As a result, the ring gear
must be accelerated to synchronize speeds. You are however limited in
doing so by your engine governed speed, and may not be able to reach
synchronization to allow the shift to take place. If the shift is not
completed , the axle will be in neither HIGH nor LOW range and all
driveline retardation will be lost.
Ratio extender use
Low End
A 2±speed axle can be used as a ratio-extender when split shifting is not
necessary. For low end use, just shift the axle into the LOW to start out,
and shift to HIGH when the extra torque is no longer needed.

High End
To use the 2±speed axle as a high end ratio-extender, stay in the LOW
range for normal upshifts and only shift the axle to HIGH on the freeway
for greater road speed.

DRIVING THROUGH WATER
Do not drive quickly through standing water, especially if the depth is
unknown. Traction or brake capability may be limited and if the ignition
system gets wet, your engine may stall. Water may also enter your
engine's air intake and severely damage your engine.
If driving through deep or standing water is unavoidable, proceed very
slowly. Never drive through water that is higher than the bottom of the
