Loosen the set screw under the top tension assembly

a couple turns as it fi xed into an undercut into the top

tension base. (Screw A,

Figure 1.4

on previous page.)

Note that the set screw is on about a 30° angle to the

machine front cover. Loosen the slotted set screw at

the rear of the top tension base and rotate the split bolt

until the spring returns to the end of the slotted groove

when pushed and released. Re-tighten the set screw

fi rmly.

If the take-up spring needs replacing, remove the ten-

sion parts and split bolt and carefully work the spring

around until it can be removed. Replace with a new

take-up spring (Part #QM10197). Make sure the split

bolt is inserted all the way into the base and retighten

the slotted screw. Adjust the take-up spring tension so

that it barely returns to the end of its slot when pressed

to the side and released.

Figure 1.8

shows this position.

NOTE: Too much spring tension will affect the stitch

quality.

Reinstall the top tension parts on the split bolt and then

the assembly into the machine front cover and tighten

the set screw.

Radial postion: When the top tension assembly is prop-

erly installed into the machine front cover, the straight

part of the take-up spring (before the loop) will be

straight up at 12 o’clock (or a little bit towards

11 o’clock). (

Figure 1.4, Position B on previous page.

)

Check that the top tension knob is not too loose

on the

split bolt and that it has some resistance so that it will

not vibrate loose while sewing.

If a correction is necessary:

To correct: remove the knob, detent washer and cone

spring, adjust the split bolt by spreading with a fl at

screwdriver until the knob has adequate resistance to

keep its setting.

Caution:

The split bolt is hardened and if adjusted too

much it may break. The top tension assembly will

then needs to be replaced. (Top Tension Assembly Part

#QM10198)
