This adjustment positions the feed wheel on its shaft so that the first
component is centered in front of the pushers when the feed wheel is
indexed.
If the feed wheel is not adjusted properly, the component will not be
centered.  If it is offset too far, the tabs on the upper pusher could hit the
leads when the component is loaded into the carrier clip. This may cause the
leads to back up or break the carrier clip.
There is also a danger that the cutters will cut through the leads to the
component instead of through the center of the holes in the cardboard strip.
This would cause excessive wear on the cutters.
Prerequisites:
Forward Stroke Adjustment
Return Stroke Stop Adjustment
Anti Back Up Dog Adjustment
Machine is powered up
Special Tools:
Pitch Wheel Tool     
To adjust the feed wheel, perform the following procedure.
1.If necessary, load components into the feeder and index the feed wheel
until the first component is in front of the driver.
2.Palm the machine down and manually push the main driver forward
until the component carrying cardboard strip stops the cutter.
3.Check to see if the leads are centered in the notches of the upper
pusher.
4.If the leads are not centered in the notches, loosen the two socket head
cap screws which hold the clamp plate to the feed wheel as shown in
the illustration.

6.While holding the feed wheel in place with the pitch wheel tool,
alternately tighten the cap screws.

End of procedure

Adjustment of the forward stroke will ensure that the sequencer chain clip
can secure the component from the feeder without being damaged.
This adjustment should be performed on a workbench with an outside air
supply of 80 psi available.
To adjust the forward stroke, use the following procedure.

1.Power down the machine and perform Lockout/Tagout according to
local procedures.

2.Remove the feeder from the machine and place on a suitable work surface.

3.Apply air pressure to the feeder and measure the distance between the front of the machined housing and the front of the dispenser driver.

4.If the dimension is .656 inch (16,66 mm) as shown in the illustration, no adjustment is required. If not, continue with step 5.

5.Retract the driver. Loosen the hex jam nut on the shaft of the pneumatic cylinder and thread the shaft into or out of the driver block as necessary.

6.Check the dimension and repeat step 4 until the proper dimension is achieved.

7.Tighten the hex jam nut.
