It is important to keep the cable (fig. 28) properly adjusted; when disengaged, the lever must be free and in the
zero position. To engage the brake, move the lever (n°7 fig. 1) to the "P" position. When the parking brake is
engaged (fig. 2P) and the PTO is disengaged, it is possible to temporarily leave the steering seat without that
the engine turns off.
THE MACHINE DOES NOT REMAIN IN NEUTRAL
Adjust the flow of oil in the hydraulic motor using the register (fig. 29). This must be done with the motor cold.
