Unscrew and remove the plastic knob (A),
followed by the spring (B) and collar (C) from the
hub, Fig.8.
Fig 8
Slide the spool (not provided) over the hub,
ensuring that it sits snugly, and replace the
collar, spring and plastic knob, tightening it
sufficiently to allow the spool to rotate smoothly
but with a slight amount of braking friction.
Do not over tighten as this will exert undue
pressure on the wire drive motor and may cause
serious damage.
Threading the Welding Wire (Fig.9)
Loosen the plastic knob (A) by turning it
anticlockwise, (this device maintains pressure on
the wire).
Pull, on the plastic knob, so that the screw rod
hinges out of its slot. This releases the pivoted
pressure roller bracket (C). Raise the bracket
and pull out any wire that has been left in the
wire liner (D), pulling it from the nozzle end of
the hose.

Pull out the end of the wire from the rim of the
spool, taking care NOT to release it. The spool is
wound firmly and should remain this way.
