11.26 AUXILIARY DRIVE BRAKE
The machine is equipped with an auxiliary drive brake,
which brakes the wheels in situations, when the pressure
in the hydraulic circuit drops (engine shut down, air in the
hydraulic circuit, result of using the “Emergency stop”
buttons). The auxiliary drive brake works on the principle
of a band brake, where the braking band brakes the pulley
of the hydraulic motor and consequently also the wheels.
The brake is controlled by a brake cylinder, which is
connected to the filling circuit of the hydraulic pump. The
braking effect will take place when the pressure in the
hydraulic system drops. When the pressure in
hydraulic system increases, the brake will be disengaged.

The brake includes a system, which allows the brake to be
manually disengaged. If used together with the hydraulic
by-pass, the machine can be moved without using its own
drive (pushed, towed away). This system of moving may
be used only when the hydraulic drive is not functional and
the machine cannot use its own drive.
-
For manual manipulation with the machine secure the
brake lever by the Secure pin in position 1 (see
figure)
- For normal operation if it absolutely necessary that the
hydraulic by-pass bolt on the hydraulic pump is
tightened and the Secure pin of the auxiliary brake
released
– position 2 (see figure)
Before operation, make sure that the
hydraulic pump by-pass bolt is tightened
and the Secure pin of the auxiliary drive
brake released (position 2)
Incorrect release of the auxiliary drive
brake Secure pin may lead to undesirable
behaviour of the machine on slopes, the
machine may uncontrollable drive down
the slope
Daily check the brake lining. If the lining
gets thinner than 1 mm, replace it
immediately. Have the brake adjusted by
an authorized service/dealer (every 200
operating hours).
The auxiliary drive brake is designed only
to brake the wheels during the drop of
pressure in the hydraulic circuit and may
not be used for securing the machine and
parking on slopes
