BobbinTension

e bobbin tension is the foundation tension

for the entire machine. Always set the bobbin

tension rst.

To test that bobbin tension is correct, hold the

bobbin case in the palm of your hand with the

open end facing up – wrap the thread around the

index nger of the opposite hand and while pulling

up on the thread move the nger side to side

(not up and down which is not consistent), the

bobbin case should li up on its side, but not li

out of your hand. If it will not li up onto its side,

it is too loose and if it lis out of your hand it is too

tight.

e small screw in the center of the tension spring

is where the adjustment is made (Figure 13).

Turn clockwise to tighten and counterclockwise to

loosen the bobbin case tension.

NOTE: Check the bobbin tension each time a new

bobbin is inserted.

Note: It is not suggested

that the lever on the

bobbin case be used

for this installation.

e latch lever should be

used only for removal of

the bobbin case.
