8) MECHANICAL MAINTENANCE
1. ADJUSTMENT OF BOTTOM SHAFT: SHUTTLE HOOK, FIGURE 16,17
A. Loosen both screws (2) at the bottom side of baseplate. By this the eccentric of segment
gear is loosen.
B. By the screwdriver (3) set the play of shuttle driver (7) in value 0,1mm or lower by
turning of the eccentric.
C. Check if there is no axial movement of the eccentric - ring (4) must be without any play
with the casting of baseplate.
D. Tighten both screws (2).
Fig. 16 Fig. 17
2. A. ADJUSTMENT OF NEEDLE AND HOOK: SHUTTLE HOOK (CB)
The hook in connection with the needle must be set so that the edge is in the position of
lower relief of needle when the hook is taking the loop of upper thread. Figure 20, detail A.
Recommended process, Figure 18,19,20:
A. Set the needle into the lower reversal point by turning the hand wheel. Put the stop
sleeve (2) on needle bar and insert the scale (4) between stop sleeve and bushing (3).
Tighten the screw (5) so that there is no play between the bushing, stop sleeve and
scale. The thickness of the scale for shuttle hook is 2.5mm.
B. Remove the scale (4) and pull the scale (2) onto the bushing (3) by turning the hand
wheel.
C. In this position the ege of the hook must be in the axe of the needle. Loosen the
screw (1)(Fig. 18) and turn with the shuttle driver (7) (Fig. 20) to the position so that
the hook (8)touches the shuttle driver by turning in clockwise. In this position the
edge of the hook must be in the axe of the needle. The screw (7) is loosen so there is
neccessary to set this screw in contact with the needle, Figure 20, detail B. It is used
as protection of the hook.
D. Loosen the screw (1)now and move with the needle bar so that the edge of the hook
(8), which is in the axe of the needle, is placed just above of lower edge of hook relief
(1), Fig. 22. Tighten screw (1).

F. Loosen the screw (5) and set the edge of the hook in distance of 0.05 - 0.1mm from
the hook relief (9) by turning the eccentric. Figure 20, detail A.
G. After that set the distance from the axe of the needle and the edge of hub of hook
relief (4) in value 7,5mm.
H. Put the ring of the hook (3), lock safety levers (2) to vertical position and check if all
screws are tightened carefully.
I. As this process is not so easy and there is neccessary to do more operations,at the
same time,it is recommended to check all values after adjustment or do it once
again.

tightening the screw (5) check the position of the needle in the middle of sub
presser foot (7), Fig. 25, 27.
C. Loosen safety screw (4), Fig. 26 and set the screw (12)to the end right position in
round slot of the lever, Fig. 25.
D. Set the screw (11)so that there is touch with stopper of hand screw (10), Fig. 25.
E. Set the play between driver of presser bar (6)and bushing of presser bar (8)in value
9mm, Fig. 27. After that tighten the screw (4), Fig. 26.
F. Tighten all srews carefully.
G. Set needed height of the stroke of sub presser foot (7). This is done by moving of
the screw (12)in round slot of the lever, Fig. 25.
H. The height of presser foot (7) is set in comparison with thickness of the material by
hand screw (10).
Summary: sub presser foot (7) should be moved with delay in value 5mm of trace of the
needle in moving from lower reversal point. The sub presser foot may not be in touch with
the materials at movement of the material when the needle is over the material.
5 . PROGRAMMABLE PRESSER FOOT
The machine could be equipped by programmable
presser foot
-parameter 34 ON/OFF.
The parameter is controlled by pneumatic valve (1).
The height of presser foot is set by screw (2).
The height of programmable presser foot is set by
screw (3), Fig. 28.
Fig. 28
6. THREADING OF UPPER THREAD
Lead the thread from thread stand to guides (1)on the head of the machine. After that
thread through silicon oil bottle for lubrication. After that thread through tensioner (3), guide
(4), tensioner (5) and spring (6), guide (7) which is under the spring (6), needle lever (8),
guides (9) and (10)and guide (11)to the needle. Please keep the direction to the needle (12),

7. ADDITIONAL TENSIONER FOR EXTRA HEAVY MATERIALS XH
This tensioner (1)
is helpful with sewing of two thicknesses of materials. It divides the tension
of the thread in combination with main tensioner. By this the stitch composition is perfect
and setting of tension is easier, Fig. 30.
It is pneumatically actuated, parameter 51 ON/OFF.

MP00800EN_161116 19
8. ADJUSTING THE MECHANISM OF OPENING OF UPPER THREAD
Opening of plates (3) of main tensioner is actuated by pneumatic valve (1)which is
connected with rod (2), Fig. 31. This valce is controlled by parameter 16. This parameter
indicates the position of the needle when the plate is opened. These plates are opened at
last trimming movement. It ensures sufficient length of upper thread after trimming so
that the first stitch with next sewing operation is done properly and there is no risk of
removal of the thread.
Correct movement and size of opening of plates is set by position of rod (2) when the
control pin of main tensioner (4), Fig. 32 is in touch of stagnation area of rod (2). We are
oriented by distance from the edge (6)of stagnation area (5) with adjustment of point of
touch of pin (4). This point of touch afects the size of opening of plates.
Set the value in 0.6mm for general materials and 0.8-1mm for heavy materials.
It is done by loosing nut (7) and turning of piston rod of pneumatic cylinder. Finally
tighten the nut (7).

9. ADJUSTMENT OF WIPER
Adjustment of the position of wiper, Fig. 33. Its Function is to take out upper thread after
the trimming. Make sure that the upper thread ends are on the reverse side of material
when starting new section of sewing after the trimming.
A. Loosen the screw (5) on the shaft of wiper (4). Set the height of wiper so that it must
go through the space between needle and presser foot. The needle is in stopping
position of the machine. The distance from the needle is 1mm.
B. Press the lever (3) in the direction of the arrow and loosen the screws (1). Set the play
of wiper from the axe of presser foot in value 10mm in extreme position. Tighten
screw (1).
Fig. 33
C. Turning ON and OFF of wiper
Use the button (1)on the cover of solenoid
for turning ON/OFF, Fig. 34.
