Angles To The Feeding Direction - Husqvarna 6690 Manual

The needle bar frame
The center position of the needle at right

angles to the feeding direction.

Requirements
The needle shall be in the centre of the needle
hole in the stitch plate.
Adjustment
Set the needle at the highest position. Turn on
the main switch five-six times and check that
the needle stops at the same position (Control
of the calibration of the step motor). If this is not
the case, see page 36. If, it stopsat the same
position, turn the handwheel until the needle
eye is at the same level as the stitch plate.
Remove the cassette and unscrew the screw
(4/43), which holds the front panel in place.
Press the front panel forwards and remove it.
Insert the special screwdriver (Adam key)
into the opening for the thread take-up
lever and loosen the set screw (4/7). The
shaft (8/4) which supports the needle bar
frame is eccentric.
Hold the needle bar in the feeding direction
and turn the shaft (8/4) carefully, by means
of a screwdriver. Investigate if the required
needle position can be obtained. If so, fix the
shaft with stop screw (4/7).
Comments
If the shaft (8/4) is shifted axially, this will affect
the needle position in the feeding direction.
If the required needle position cannot be obtained,
fix the shaft at a middle position and adjust the
needle position as follows:
Remove the rear cover. Fit the box spanner
411 1907-01 on the nut (8/30) and loosen the screw
(8/29) in the centre of the nut. Turn the box spanner
until the required needle position is obtained.
Tighten the screw.
