LOADING SPOOLS OF WIRE

•Keep hands, hair, clothing and tools away from rotating equipment.

•Do not wear gloves when threading wire or changing wire spool.

•Only qualified personnel should install, use or service this equipment.

------------------------------------------------------------------------

Loading 10 to 15 lb. (4.5 – 6.8kg) Spools.

A K468 spindle adapter is required for loading 2" (51mm) wide spools on 2" (51mm) spindles. Use a K468 spindle adapter for loading 2-1/2" (64mm) wide spools.

1.Squeeze the release bar on the retaining collar and remove it from the spindle.

2.Place the spindle adapter on the spindle, aligning the spindle brake pin with the hole in the adapter.

3.Place the spool on the spindle and align the adapter brake tab with one of the holes in the back side of the spool. An indicator mark on the end of the spindle shows the orientation of the brake tab. Be certain the wire feeds off of the spool in the proper direction.

4.Re-install the retaining collar. Make sure that the release bar snaps out and that the retaining collar fully engages the groove on the spindle.
