Disconnecting the brake lines
After disconnecting the brake hose with the
red coupling button, braking is initiated =
automatic braking. Manoeuvring is then no
longer possible.
Brake cylinder
If the operating pressure of the compres-
sed air brake falls below 3.0 bar, the spring
of the brake cylinder will lock the braking
system. In doing so, the brake rod (8) mo-
ves out and applies the braking system via
the brake lever (9). If the brake lever (9) is
swivelled more than 40 mm, the braking
system must be readjusted.
Rapid emergency brake
If the brake lines are interrupted when the
implement is disconnected from the tractor,
emergency braking is automatically enga-
ged, using the operating pressure of the
compressed air reservoir.
