drum). In the case you are replacing the wire
spool, extract it.
• Remove the plastic protection from the spool.
Place it on the spool holder. Tighten the lock
nut turning it.
The unit can also accept 100 mm dia-
meter wire spools. For the mounting
follow these instructions:
• Remove the wire spool from the spool holder.
• Loosen the nut, mount the new spool and the
