1.1. Mechanical Release of the Parking Brake

Mechanical Release of the Parking Brake

------ WARNING! ------

Personal injury or death could result when towing a disabled machine incorrectly.

Block the machine to prevent movement before releasing the brakes. The machine can roll free if it is not blocked.

------WARNING!--------

After a failure of the air compressing system, the parking brake can be released mechanically. Loosen counter nut (2, Fig. 690) and turn adjusting screw (3, Fig. 690) in until the brake is released. The machine can now be towed.


NOTICE

Engage parking brake immediately after towing.


If the machine must be towed, shift the drive transmission in the undercarriage manually from low gear or high gear to neutral (detent position on shift cylinder). For high gear position the cylinder is completely out; for low gear, completely in.

With the engine running move the speed selector (4, Fig. 621) into neutral position. Lift the shift lock above selector for shift change if necessary.

With the engine stopped the shift cylinder on the transmission can be moved by hand regardless of the position of the speed selector (4, Fig. 621).

To do so loosen four hex head bolts, remove the cover and insert a bolt into the shifting rod (Fig. 787).


NOTICE

Towing the machine without shifting the drive transmission to NEUTRAL will damage the hydraulic drive motor.


If machine should be towed with engine running make sure that the speed selector (4, Fig. 621) is moved into neutral before the engine is started. If not, the selected shift range is hydraulically operated.
