2.2.4 Disengaging the brake when towing

WARNING

On a slope, chock the drums and prepare for towing before disengaging the brake.

For towing the machine when the engine is disabled or when troubles have developed in the
hydraulic system for propulsion, disengage the brake as instructed below:

1) Turn the valve knob clockwise until it stops.
2) Pull up the pump knob and push it. Push it about eight

times, and the parking brake will be released.

3) After traction, be sure to turn the valve knob

counterclockwise until it stops.

WARNING

• Do not try to release the brake immediately after

a hot engine has been stopped. Let the oil cool
down.

• For the brake disengagement, wear hard hat and

safety goggles.
