Changer Extend Timing:
The changer could shift prior to reaching its full back feed position, and possibly miss the intended pickup hole if the extend timing is too early (-160). There will be more movement in the feed bar as it moves farther from the forward point when the changer switches. The normal motion of the press moves the stock forward station about 10:00 and continuing until around 4:00. If this additional feed bar movement peaks at around 12:00, it will further accelerate the stock forward. The stock can be flung ahead of its normal position if this happens before the stock retard pins engage. This will result in the loss of progression.

Changer Retract Timing:
If the retract timing is tool early, the feed bar will appear to stall or come to a stop on its way toward forward feed. This might lead to more wear on the bearings. Advancing the timing (larger values) will cause ****this stalling out effect to blend better**** with the normal stopping that occurs at forward feed.

...could you help me understand this part? does it mean that this effect ceases the stall condition (stall ...out)??
