621G Wheel Tractor-Scraper Caterpillar


Parking Brake

Usage:

621G ALP

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

Personal injury could result from the sudden stop of the machine.

If the brake system air pressure drops below normal operating pressure, an action alarm will sound and the brake alert indicators on the operator's panel will flash. The action light will start flashing. If the air pressure continues to drop further, the parking brake will engage automatically. Be prepared for a sudden stop.

Correct the reason for the loss of air pressure. Do not move the machine without normal brake air pressure.



NOTICE

Moving the machine with the parking brake engaged can cause excessive wear or damage to the brake. If necessary, have the brake repaired before operating the machine.
