GENERAL ADJUSTMENTS - FOREWORD
All the necessary adjustments for correct bar feeder operation are included. They may become
necessary for maintenance, troubleshooting or component replacement.
5.2.1 Feeding chain - Adjustment
For the movement chain of the bar pusher, tension
screws A on the rear plate of bar feeder is provided.
After some bar feeder operating hours, the chain
tension has to be checked.
• If bush B of chain tension is still fastened to the
rear plate, then no chain extension took place.
• On the contrary, if bush B moved away by 1- 2
mm from rear plate, then a chain extension took
place, which is dangerous for correct operation of
bar feeder. Screw A must then be tightened until
bush B is fastened to the rear plate.
5.2.2 Air adjusting unit - Adjustment
After unscrewing the glass protection, the
pressure switch can be properly adjusted by
turning the relevant adjusting screw (G). Proper
setting is 4.5 bars (0.45 MPa).
WARNING - CAUTION:
Do not further turn anticlockwise when
the green pointer is on 0. This may
cause damage to the pressure switch.
INFORMATION:
Lubricator D is fitted only when the
headstock synchronization device is
assembled.
