NOTE
If it becomes necessary to switch off a truck
with a faulty parking brake, always secure the
truck to prevent it from rolling.
A possible cause of the malfunction is that
the parking brake cannot determine whether
the truck is stationary or still in motion. The
following section describes how to actuate the
parking brake when it is faulty:
Actuating a faulty parking brake when the
truck is stationary
There are two ways to apply the parking
brake:
–
Press and hold the push button (1) for at
least five seconds and then release the
push button.
or
–
Press the push button (1) several times in
succession so that the push button is actu-
ated for a total of five seconds.
The parking brake is applied with an audi-
ble sound. After the push button is released,
the parking brake should not make any fur-
ther sounds; if a sound is heard, this means
the push button was pressed for less than
five seconds. In this case, press the push but-
ton again to apply the parking brake again.
Repeat this process as necessary until the
parking brake applies and the symbol ap-
pears.
