OPERATION 151
MACK POWERLEASH™ ENGINE BRAKE (IF
EQUIPPED)
Note:
If your vehicle is equipped with a Jacob’s engine brake, please refer to the
Jacobs Engine Brake Manual supplied with the vehicle for complete operating
instructions.
Engines may be equipped to be PowerLeash™ upgradeable. These engines
will be equipped with PowerLeash™ camshaft. These engines are identified
on the engine information sticker.
If your vehicle is equipped with the MACK PowerLeash™ Engine Brake, it is
important that you take the time to become familiar with your engine brake
before putting it into operation.
WARNING
Operation of any vehicle on wet or slippery roads requires extreme caution.
Because the engine brake converts the engine to a retarding device, it should
NOT be used on wet or slippery roads if the vehicle has a single driving axle
or if it has tandem driving axles that are lightly loaded. Use of an engine
brake under these conditions can cause the vehicle to skid or a combination
vehicle to jackknife.
Engine Brake Switch
The Engine Brake switch is located on the dashboard. The Engine Brake
switch is a three-position switch located on the instrument panel.
