TM 9-2350-247-20-1 THEORY OF OPERATION — Continued 0003 00 PIVOT STEERING AND BRAKES (M548A1) Pivot steering brakes are disk brakes and work like the differential brakes, but quicker. Only use disk brakes in the water or when stopped. Speeds above 10 mph (16 km/h) damage disk brakes. AUXILIARY AUTOMOTIVE SYSTEM The auxiliary automotive system includes driver controls, vehicle compartment heater, bilge pump, and fire suppression system. The driver controls regulate the engine, transmission, steering, and braking systems of the carrier. The fuel shutoff control is used to stop the supply of fuel to the injectors. To start the engine, the driver must push in the fuel shutoff control. The throttle linkages are used to control the engine speed. The gear selector allows the driver to choose the proper gear for the carrier. The steering and braking levers control separate right and left steering brakes in the control differential on M548A1. By pulling the levers, you can slow or stop either track for steering, or both tracks at once for stopping. A lock button at the top of each lever lets you set and lock the brakes for parking. On M548A3, the steering wheel controls steering and pivoting turns. On the M548A3, when the brake pedal and parking brake are applied at the same time they will hold the carrier. 0003 00-14 Change 1
