Lubrication of the Hook
Apply one drop of oil to the raceway of the bobbin case support two to three times per day. This
application is based upon sewing for 8 hours of machine time. If the machine is used less, lubricate
the hook less frequently. After the lubrication of the hook, it is recommended that one momentarily
sew on scrap material before resuming the sewing of the quilt. Failure to do so may result in oil stains
on the quilt piece.

The following observations, accompanied by necessary adjustments, will ensure trouble-free thread
passage. Failure at any of these points will significantly affect thread tension.
