Required:
1 - Bobbin drive pulley
1 - Flyer drive pulley
1 - 2mm Allen key
(in the hardware bag)
Start with the bobbin drive pulley, it is the large thin pulley with two black grooves. On the head find the 4mm
hole in the aluminium bearing housing and turn it until it is ‘upward’. Find the threaded hole on the bobbin
drive pulley and make sure the grub screw is removed.

Now slide the bobbin drive pulley carefully onto the head and align the threaded hole DIRECTLY over the hole
in the bearing housing. Good lighting will make this task easier. When aligned, screw the long 10mm grub
screw into the threaded hole with your 2mm allen key and secure the pulley to the head. The screw will go
in easily, if it does not, pause immmediately, remove it and recheck your alignment. Screw it down firmly and
when finished, it will be flush with the top of the threaded hole.
Now you need to put on the flyer drive pulley which is
smaller and thicker with three drive band grooves. Find
the flat ground into the 8mm (~5/16”) flyer shaft and turn
the shaft until the flat is ‘upward’. There is a threaded hole
on the flyer drive pulley too and you now need to locate
this, checking the grub screw is removed.
