OPERATION
To
get the best result from the Extarder compression brake, it
is necessary to observe several simple operating principles.
The Extarder compression brake is activated when the fol-
lowing conditions are satisfied.
1.
The Extarder dash ON/OFF switch is in the on position.
2.
The engine is not being fueled (foot off the throttle pedal).
When the Extarder's dash switch is turned
ON and your foot
is removed from the throttle pedal, the transmission should
be shifted to a lower gear. This allows the Extarder compres-
sion brake to provide the maximum retarding power.
Operation on Wet
or
Icy
Roads
It
is recommended that on wet and slippery or icy roads that
the Extarder not be left in the automatic mode. The
ON/OFF
switch should
be
in the OFF position.
Operation
of
the Extarder compression brake is recommend-
ed only when you have good traction with the road surface.
Operation on wet roads should be undertaken with extreme
care and at the driver's discretion.
