OIL PLACES AS INDICATED BELOW
TO CHANGE THE LENGTH OF STITCH
The regulator is located at the right end of machine on the front side of arm,
TO SHORTEN stitch move the lever down. TO LENGTHEN stitch move lever up
No. 1 indicates the shortest, and No. 7 the longest stitch.
TO REGULATE THE TENSION
To loosen the tension, turn the thumbscre'W on the dial to the
left which will move the pointer toward figure 1. To tighten it, turn
to the right, moving the pointer toward No. 8. By this means the
same tension can always be duplicated, thus obviating the necessity
of experimental trials, as is the case with other machines. If a tight
tension is desired, both upper and under threads must necessarily be
tight. If the upper thread is tight and the lower thread loose, tiie
upper thread will be drawn to the top thus If the low­
er thread is too tight, it will be drawn straight on the bottom of goods,
thus;
' When you desire the goods to look alike on
both sides, and be elastic, balance the tension thus;
THE TENSION RELEASER
The tension releaser is operated by the presser-bar lifter. By
means of it, all tension is taken off the upper thread when the
presser-foot is raised, and the work can be taken out without pulling
the thread down by hand.
PARTICULAR NOTICE—The tenshn cannot is regulated when the lifter is up
because the Releaser is operated by the presser-bar lifter,
