Needle Height - Husqvarna 1200 Service Manual

10 The needle height
Requirements
Set the machine for zig-zag, right-hand position,
Setting 6 mm stitch width.
Move the needle upward by pulling the short cog
position belt in toward the machine and at the same
time holding the hook downward, backward.
When the tip of the hook reaches the centre line of
the needle, the underneath of the tip should be in line
with the top edge of the needle eye.
Comment I
The gap between the tip of the hook and the needle eye
is influenced by the timing of the hook in relation to the
needle. Therefore check the timing according to the
previous page before making any adjustment.
Comment II
The gap between the tip of the hook and the needle
eye, with the needle at the centre position (1.5mm)
is the starting measurement but as this is difficult to
estimate, use the corresponding measurement with
the needle at the right-hand position instead.
Adjustment
Set the machine for zig-zag, right-hand position, 6mm.
Move the needle upward by pulling the short cog belt
in toward the machine until the tip of the hook reaches
the centre line of the needle.
Push the hook downward and hold it, so that the catch
of the hook rests against the left side of the slot in
the driver.Loosen the screw (A).
Move the needle bar in such a way until the underneath
of the tip of the hook is in line with the top edge of
the needle eye.
Tighten the screw (A).
NOTE!
Check that the needle eye is at right angles to the hook
by fitting a twin needle and observing the needle
positions in the needle hole of the stitch plate.
