3.11

Working brake is activated from the tractor driver's seat by pressing on the brake pedal in the

tractor. The control valve activates the sand spreader brakes when the brake pedal is

pressed in the tractor. Furthermore, in case of an inadvertent disconnection of the conduit

between the sand spreader and the tractor, the control valve will automatically activate sand

spreader's brakes.

Valve used in the system is equipped with a circuit causing the brakes to be applied when

sand spreader is disconnected from the tractor. When compressed air conduit is connected

to the tractor, the device automatically applying the brakes now changes its position to allow

normal brake operation.

Three-step brake force regulator in pneumatic system adjusts braking force depending on the

regulator's setting. Switching to a suitable working mode is done manually by sand spreader

operator using the regulator lever prior to moving off. The regulator has 3 working positions:

"no load", "half load", "full load".
