Wire Threading Procedure
Wire Spool Installation
Release latches, and open right side door of cabinet (Reference Cobramatic ®
Pro Series Assembly drawing).
Remove spool retainer nut from spindle hub (Reference Cobramatic
®
Pro
Series Spindle Brake Assembly drawing).
Raise wire retainer bar to latched position (Reference Cobramatic ® Pro
Series Assembly drawing).
Install wire spool onto spindle so that wire feeds from bottom of spool
towards slave motor. Make sure that the hole in the wire spool aligns with
pin on spindle. The white dot on the end of the spindle will aid in this align-
ment.
Replace the spool retainer nut.
Lower the wire retainer bar onto the spool.
