TM 9-2320-280-10 WARNING Do not rely on service brakes after fording until the brakes dry out. Keep applying brakes until uneven braking ceases. Failure to do this may cause damage to vehicle, and injury or death to personnel. (6) Place transfer case shift lever in desired range.

Hydrostatic lock most frequently occurs during or just after fording. Water is forced into the air intake system, drawn into the engine, and effectively "locks-up" the engine. • Notify unit maintenance if you suspect hydrostatic lock, and they will further test the engine. d.
