THREAD JAMMING
The Master Tool Cub, as all sewing machines, must be threaded properly and used with the
correct needle and thread combination. Because of its unique design, the Master Tool Cub
reacts a little differently to improper threading.
The thread may catch on the hook and the machine will jam.
Do not attempt to free the
thread by cranking over the machine.
The spring-loaded shuttle hook must be freed first:
1) Cut and clean out the misplaced thread. The hook
(A)
should then snap back into place.
2) If the above fails, loosen the two race cover screws
(B)
until the hook
(A)
has snapped
back. Do not remove the race cover
(C)
. After the hook
(A)
is back in place, retighten the
race cover
(C)
.

Important Note:
Never operate the machine with the presser foot raised.
