REMOVAL
WARNING
· Whenever the air compressor safety valve is
removed and installed for any reason, a
stationary locomotive airbrake test (para 2-9)
must be performed to check that the air
compressor safety 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
air compressor safety valve. Residual air
may escape and cause injury to personnel.
