3.11 Install Wire into the Feedhead
!
WARNING
ELECTRIC SHOCK CAN KILL! Make certain the machine is unplugged from the power receptacle. Do not
plug machine in until told to do so in these instructions.
Load the Wire Spool
Slide the wire spool onto the hub, loading it so that the wire will feed off the spool as the spool rotates counter-
clockwise.
Make sure that the locating pin on the spool hub lines up with the hole in the spool.
When the spool of wire is in place, replace the spool retaining pin.
NOTE
The hub tension has been pre-adjusted at the factory. However if adjustment is required, simply turn the
spool nut counter-clockwise to reduce tension, and clockwise to increase tension.
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 do not let go of it. Make sure that the end of the wire is free of any burrs and is
straight.
