3.11 Installing Wire Spool
As delivered from the factory, the unit is set for a 33/44 lb. or 12" (300mm) spool.
Installation of wire spool
1. Remove Wire Spool Hub Nut by turning counter clock wise (to the left).
2. Remove the spring from the hub.
3. Place Wire Spool onto the hub, loading it so that the wire will feed off the bottom of the spool as the spool
rotates counter clockwise. Make sure to align the spool alignment pin on the hub with the mating hole in the
wire spool.
4. If using a 10 lb. wire spool place the spring on the exposed hub. Do not use the spring for larger wire spools
that cover the entire hub.
5. Replace the Wire Spool Hub Nut by turning clock wise (to the right).
NOTE
The Hub tension has been pre-adjusted at the factory. However if adjustment is required, refer to section
3.12 and Figure 3-12.
CAUTION
Use care in handling the spooled wire as it will tend to “unravel” when loosened from the spool. Grasp the
end of the wire firmly and don’t let go of it.
