A-1 CHARGING CUTOFF PILOT VALVE
This task covers:
Tool kit SC4940-97-CL-E12
· Whenever the A-1 charging cutoff pilot valve is removed and installed for any reason, a stationary
locomotive airbrake test (para 2-9) must be performed to check that the A-1 charging cutoff pilot
valve functions properly in the brake equipment arrangement. Failure to perform test may result in
injury to personnel.
· Make sure air is drained before removal of the A-1 charging cutoff pilot valve. Residual air may
escape and cause injury to personnel.
When removing or repairing brake valves or components, check air lines and pipes for corrosion,
breaks, splits, or loose connections. Repair of air lines and piping consists of replacing defective
pipes, lines, and connections. Refer to TM 55-2210-224-24P for identification of piping.
