SERVICE MANUAL –ALPHA SL 65S

P04 Pusher reverse position

The pusher retracting DISTANCE to avoid its tip contacting
with rotating spindle.

Position

Current pusher position measured from home position SQ2.

Pusher Rev. Distance

The DISTANCE that the pusher should RETRACT. Normally
5mm after the bar stock.

Due to there is no rotating adapter between the pusher and the bar stock, the pusher tip must not contact any rotating
component or it will be damaged. Below is the summary for those cases and their solutions :

Situation

Solution

Parameter

The pusher touches the bar stock
rear end.

Keep the pusher away from the rotating bar
stock when feeding is accomplished.

P04

The pusher touches the rotating
spindle because its tip is drooped.

Keep the pusher behind the position where
its tip starts to droop to the rotating spindle.

P02

P04 distance
