To ensure that components with small lead diameters will be accurately sensed while maintaining the ability to detect missing components, the overlap of the refire housing to the component support must be set.
Prerequisites:

Machine main power is on, machine is palmed down. To adjust the feeder refire assembly, perform the following procedure.

1.Loosen the refire housing screws. Adjust the refire housing until the refire contact is flush to within .010 inch (0,25mm) overlap with the edge of the component support section of the cutter holder. Refer to the illustration.

2.Loosen the screws and alternately adjust the position of the feeder cover and the refire housing until the results described in step 1 are achieved. Ensure that all screws are tight when the setup is completed.

End of procedure.

This adjustment positions the feeder on the sequencer module so the pusher aligns with the carrier clip.
When properly aligned, the component's leads contact the clamps on the carrier clip forcing them open at the same time.  This action puts equal force on both leads and prevents the component from twisting as it is being loaded
into the carrier clip.
If the feeder is not correctly aligned to the carrier clip, the clip fails to center to the pusher when it extends.
Prerequisite Adjustments:
Carrier Clip Alignment to the Cutter Station
Carrier Clip Alignment To Component Transfer Upper Guide
Feeder Preliminary Forward Stroke Adjustment
Machine is powered on and the interlock bypass key switch is turned to the ON position
Special Tools:
Feeler Gauge Setup Tool
To align the feeder to the carrier clip, perform the following procedure.

1.Remove the component carrying cardboard strip from around the feed
wheel.
2.Using IM Diagnostics, zero the chain.
3.Using the Manual Diagnostics window, turn off the main air dump
valve.
4.Manually push the main driver forward as far as it will go.

5.Insert the .030 inch (0.76mm) feeler gauge setup tool where illustrated and check the clearance.
When properly aligned, the feeler gauge is touching both surfaces and
the carrier clip is displaced as far as it will go to the left.
If adjustment is necessary, loosen the socket head cap screw, which holds the feeder on the sequencer, and push the dispenser to the left until the correct alignment is obtained.

6.After making the adjustment, retighten the socket head cap screw and withdraw the feeler gauge setup tool.
7.Using the Manual Diagnostics window, turn the main air dump back on.
8.Ensure that the main driver retracts and is clear of the chain clip.
9.Verify that the carrier clips, after being displaced to the left by the pusher, return fully to the right after the pusher retracts.
10.After completing the alignment of all feeders, zero the chain again.
11.Refer to step 5 and verify that the alignment of the feeders is correct.  If needed, repeat the entire procedure again to obtain the proper adjustment.

End of procedure

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.
