The button for temporary deactivation of brakes of the trailer or semi-trailer
The temporary trailer or semi-trailer brake deactivation button (1) is located on the dashboard panel.
Prior to using the button for temporary deactivation of brakes of the trailer or semi-trailer, it is
always necessary to provide sufficient space in front of the tractor and behind the connected trailer
or semi-trailer where no obstacles or persons will be present for the case that the effect of the
parking braking will not be sufficient and the combination of vehicles moves.
Only the air brakes are deactivated by the button for temporary deactivation of brakes of the
trailer or semi-trailer.
The button for temporary deactivation of brakes of the
trailer or semi-trailer can be used by the operator of the
tractor with the connected trailer or semi-trailer to make
sure that the effect of the parking braking system of the
tractor with the connected trailer or semi-trailer when the
tractor is braked with the hand brake is sufficient.
If there is a tractor with the connected trailer or semi-trailer
which is braked with the hand brake and the key in the
switch box is in the position (I), and we press the button
for temporary deactivation of brakes of the trailer or semi-
trailer, the trailer or semi-trailer is deactivated for the time
when the button is pressed (the trailer or semi-trailer does
not brake). When the button for temporary deactivation of
brakes of the trailer or semi-trailer is released, the brakes
of the trailer or semi-trailer are activated (the trailer or
semi-trailer brakes).
