104 72 30-26 Husqvarna service manual 23
SETTING INSTRUCTIONS
The best and fastest results are obtained if you make the settings in the
following order when servicing.
1 The hook gear
Tangential play
Requirements
Lock the handwheel and turn the driver forward
and back again.
The gear must not be completely tight but the play
should be as small as possible.
Adjustment
Remove the stitch plate. Loosen the stop screw (A)
and turn the shaft (B) until the required
play is obtained.
Comment I
The shaft is journalled eccentrically and must always
be set so that the screwdriver slot is to
the left of the centre of the hole (see illustration).
The same play in the hook gear can be obtained by
turning the shaft a half turn but the hook will then
lie eccentrically in relation to the hook cover.
The shaft is also shiftable.
Check therefore that the gap between the hook
cover and the driver has not been altered (P.24).
Comment II
Too little play results in slow running and increased wear.
Too big play results in noise and risks missing stitches.
Thereafter adjust:
Gap between the hook cover and the driver, (P.24).
Timing of the hook in relation to the needle, (P.30).
Gap between hook and the needle, (P.28).
Setting the stitch plate in relation to the needle, (P.29).
