Manual 0-5343 3-17 INSTALLATION/SETUP
3.12 Installing 33/44 lb Spool (12" diameter)
As delivered from the factory, the unit is fitted with a Wire Spool Hub which accepts a Spool of 33/44 lb. or 12"
diameter.
Installation of wire spool, Refer to Figure 3-11.
1. Remove Wire Spool Hub Retaining Clip. Grasp the loop and pull.
2. 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.
3. Replace the Wire Spool Hub Retaining Clip in the set of holes closest to the spool.
NOTE
The Hub tension has been pre-adjusted at the factory. However if adjustment is required, refer to Sec-
tion 3.18
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.
