Hardesty Power Top De-reeler

Operating Principle
The rotating of disk which shrouds the spool serves two purposes.  One is to provide a clean smoothly radiused edge on the spool end and second to provide an assist when needed to un-spool the wire.  This disk can be selected to rotate in a clockwise or counterclockwise direction.  In normal use the disk will be selected to rotate in the same direction as the wire un-spools from the reel, but when dereeling very find wire you may get better results by selecting a rotation opposite that of the wire un-spool direction.

This will help keep the wire from looping and causing kinks to develop in wire.  By rotating opposite the normal un-spool direction a slight drag is developed and the wire holds to the spool form better.  The reason we can rotate opposite un-spool direction with find wire is because the high speed rotation of the disk generates an air flow over the disk edge.  By using the "Hardesty Power Top De-reeler" dereeling force will remain very constant throughout the complete un-spooling.  This wire can be de-reeled without the use of a "Whisker Disk" or other special devices.
 

Using the "Hardesty Power Top De-Reeler"
1. Loosen locking lever on over arm.

         

 
2. Swing over arm out of way and Remove clear plastic bubble.

          

 
3.

 

 Place wire spool on caster base (center over center location).

    

 
4.

 

 Using handle, lift power top from storage tube (make sure bearing block is in contact with stop collar).

    

 
5.

 

 Align power top shaft over center hole of spool and lower shaft slowly, allow bearing block to center assembly and continue to lower until seated, now apply enough downward pressure to seat disk so outer edges of spool top are covered by disk.

         

 
6. Thread wire from spool through eyelet from inside plastic bubble.
7.
 		 Place plastic bubble over wire spool and center around spool.  (pull some wire to make sure wire is free of obstruction).
 
8.

 

 Swing over arm over bubble until eyelet aligns with eyelet on plastic bubble.  Lightly tighten locking lever.

    

 
9.
 		 Thread wire through eyelets and through felt oiler pad.
10.


 

 Connect air supply to proper rotation.

Troubleshooting

Problem
1.  Disk fails to start when connected to air. 
Note: This may be a common occurrence when new due to very low air volume metered to the air motor.

Procedure
1.  Check air supply.
2.  Make sure power disk is seated properly.  Check alignment reinstall.
3.  Make sure spool is setting squarely on foam.
4.  Agitate caster base clockwise and counterclockwise to help start disk.
 
Problem
2. Fine wire develops kinks in feed length.

Procedure
1.  This is common when un-spooling fine wire with disk turning in wrong direction and causes wire to hang up and break.  Try running disk in direction opposite to un-spool direction.

Important Notes
CAUTION:  Never De-reel wire over a non-rotating power disk.  Wire may damage disk edges.

1.  Always use center ring when handling your power disk.  Removing and installing by the disk edges could permanently damage the power disk.

2.  Always store the power disk in its storage tube.  Never leave your power disk on the floor.  Damage to the power disk edges will adversely affect the performance of the unit and may require replacement.

3.  DO NOT over oil the air supply.  Excessive oil will stall the motor.  The air is metered via an orifice to a very low volume.  Excessive oil must be cleared from motor before proper performance will resume.
