E - STANDARD MACHINE ADJUSTMENT
6. FEEDING
1. Tilt the sewing head on the rest pin.
2. Bevel Gear Adjustment.
Manually turn the hand wheel in the sewing direction to be sure the
drive disk switch spring
13
in the main cam disengages with any dog
of the drive disk worm gear hub
14
. To be in the first row of stitches
the dog of the drive disk wormgear hub
14
need to be completely
under the drive disk switch spring blade
13
, not before-as the picture
indication.
3. Remove the bevel gear cover and loosen the screws
1
and
2
on
the horizontal bevel gears and screw on the stop
3
.
4. Loosen two adjusting screws
4
in the right collar
5
. Adjust the
dimension 11mm from the end of the feed shaft
6
to the collar
7
by
pressing the feed shaft
6
against the right collar
5
. Tighten the
adjusting screws
4
in the right collar
5
. The tension of the left collar
on the shaft is set.
5. Engage the bevel gear
10
with the vertical gear
9
and tight on the
shaft flat one of the two set screw
1
. This is a preliminary adjustment,
no need to tight completely.
CAUTION:
do not run the machine with the gear
10
in this position.
6. Engage the left bevel gear
8
with the vertical bevel gear
9
and
check the teeth of the gear
8
and
10
are perfectly aligned. Use a
marking line on the shaft as a reference to obtain the gears are
aligned. If the teeth are not aligned turn the gear
8
, this operation
turns the gear
9
and consequently the gear
10
turns in opposite
direction with the shaft. Check again the marking and make this
operation again if necessary, turning in one direction or opposite, till
the teeth are perfectly aligned. Lock in this position both set screws
2
.
7. Move the stop
3
against the gear, push the stop rotating it in
counter clockwise direction (view from the front of the machine) and
tighten the set screw on the stop
3
.
8. Loosen the set screw
1
on the shaft flat, and slide the right gear
10
far away toward the back of the machine and tighten one screw
1
partially.
9. Manually turn the hand wheel in the sewing direction until the feed
shifter lever moves to its full left position and the main cam reaches
its second rest position (drive disk switch spring in the main cam
13
engages with the dog of the drive disk worm gear hub
14
for second
row of stitches). The right gear
10
is now not near the vertical
gear
9
, loose the set screw
1
on the flat and push the gear
completely toward the gear
9
to engage perfectly. To be sure the
gear
10
is completely engaged, push the shaft toward the back of the
machine, by pressing its head
6
, in the way to create a space of 0.5
mm between the lever
12
and the collar
5
, as indicated in the picture.
With the gear completely engaged in this condition tighten both set
screws
1
securely.
The bevel gear adjustment is done. By manually turning the hand
wheel finish the sewing cycle and bring the machine to the home
position. Reinstall the bevel gear cover.
