will be initiated for the current cycle only.

ballast by alternately squeezing in and out for very short periods of time.
d. If the switch is held while the workheads are squeezing in, the Squeeze Sustain
feature will be initiated for the current cycle only.

squeeze in by the long timer. This feature is used where additional squeeze in
time is desired, such as in fouled ballast.

the workheads before initiating the Tamping Cycle to clear tightly spaced or
slightly skewed ties.
