Schacht LADYBUG - REPLACING A POLY DRIVE BAND

– 8 –
cord slips and won’t wind up, you can
make a double knot about 1" from the end
of the knot. Do not cut the cord.
Now you can start spinning. To increase
the take-up of your yarn onto the bobbin,
adjust the Scotch tension peg to stretch
the spring. To decrease the take-up, adjust
the peg to relax the spring.
The poly drive band has a memory and
can be used with any whorl. Occasionally,
you will need to tension the drive band,
especially when you move from a slower
(larger) whorl to a faster (smaller) whorl.
If you nd that the drive band is slipping,
use the tensioner to add tension: pull up
the tensioner handle and slip the drive
band into the pulley (Figure 7).
REPLACING A POLY DRIVE BAND
17. Remove the yer: Place the poly or
cotton drive band on top of the rear leg, as
shown in Figure 6A on page 7.
18. Loosen the front maiden knob just
enough to allow the front maiden to move.
Slide the front maiden and the yer as far
forward as possible on the mother-of-all
(MOA).
19. Remove the yer orice from the
front bearing. Remove the yer shaft from
the rear bearing. If necessary, remove
the Scotch tension brake band from the
bobbin.
20. Using a #2 Phillips screwdriver,
remove the two screws connecting the
upper and lower front legs (Figure 8A).
21. Separate the upper and lower front
legs widely enough to t the poly drive
band through the gap (Figure 8B). If
necessary, pull the old drive band through
this gap and remove it from the wheel.
Push the new drive band through the gap.
22. Push the upper and lower front legs
back together, checking that the holes
align. Replace the screws completely in
the front leg.
23. Slip the drive band around the drive
wheel and over the whorl.
