3 Disassemble the machine
3.1 Disassemble the main shaft (Fig. 1 and Fig. 2)
Before disassembling the main shaft, it is advisable to mark the exact position
of each part or screw, and to take the measures of both bearing support blocks
by means of a gauge, measuring from the front edge of the machine column.
(Measures a + b).
This will save you a lot of time when you assemble and adjust the machine.
(Fig. 1)
Not until now should the screws of the parts attached to the shaft be loosened
and the right handwheel be removed and the shaft, too, be pushed out to the
left by a withdrawal device.
Loosen the screws of the parts. Take off the right hand wheel. Pull the shaft
about 20 to 30 mm to the left and remove the remaining glue without displacing
the ball bearings. Then take off shaft.
The left handwheel with the stitch-regulating eccentric bolt does not need to be
removed. Be sure that the set screws 176.0632 located on both sides of the
regulating eccentric bolt (A) 132.0074 are removed; on machines that were built
before 1986, the screws 176.0620, 176.0619, and the setbolts 135.0078.
(Fig. 1 and Fig. 2)
NOTE! If not done yet, mark the position of guide disc 153.0031 and
regulating eccentric 132.0074.
The remaining glue can easily be removed from the shaft by using a cleanser,
e. g. Clorothene.

4 Assemble the Machine
4.1 Mount the shaft ( Fig. 1)
First, remove any grease from the shaft. Mount the parts in correct order onto
the shaft and put it into the machine column so that it sticks out about 30 mm
on the left. Then put a drop of “Loctite” on either end of the shaft, that is, on the
left end sticking out from the column, and on the ball bearing on the right.
(Loctite, Kapillar 290)
NOTE! The surfaces to be joined must be absolutely clean. Only then
you may fit the shaft completely into the machine column. Turn
it slightly, so that the glue on the ball bearing is evenly
absorbed. Fix stitch regulating eccentric (A) (fig.1).
See chapter “4.2 Mount stitch regulating eccentric 353.0031”.
Push the shaft to the left up to the stop, and fasten setting ring
246.0103 on the right of the shaft in order to eliminate any axial
play.
About an hour later when the glue (Loctite, Kapillar 260) is hard, you may
continue to assemble and adjust the machine. When assembling after a repair,
it is not necessary to take off the left hand wheel.
4.2 Mount stitch regulating eccentric 353.0031
Fit the left handwheel onto the shaft so that the first screw in direction of sewing
fits into the drill hole on the left of the shaft and point upwards.
Turn guide disc 153.0031 so that you can easily slide down set eccentric
132.0074. Then screw the first screw 176.0632 into the regulating eccentric, but
ensure that regulating bolt 137.0026 can still freely be turned in the shaft. Then
turn hand wheel with shaft by 180 degrees. Screw second screw 176.0532 into
the regulating eccentric right to the stop. Fasten guide disc 153.0031.
Push the shaft to the left up to the ball bearing, slide set collar 246.0103 on the
right shaft side all the way to the ball bearings, and tighten. The shaft is now
fastened.
Let stitch-regulating eccentric 137.0014 level out and tighten.
Fix two lubricated springs 161.0063 and bolts 135.0062 into the drill hole of the
hand wheel (Fig. 2, Fig. 3 und Fig. 4).
13 MA_141_142_A10-6-7-3-6-5_130617_en
Fig. 3
Fig. 4
Screw knob 344.0089 onto regulating bolt 137.0026 until it touches the hand
wheel. Then hold the knob while screwing out the regulating bolt until index
124.0080 stops at the knob (mark 5) long stitch, (Fig. 4) and easily visible
between handwheel and stand.
When properly adjusted, you can easily turn the regulation knob from the fixed
stop “long stitch” to the fixed stop “short stitch”.
Regulating eccentric 132.0074 must be set to the upper dead point, the index at
the hand wheel to mark 5. Finally, screw in lock nut 179.0614. (Fig. 4)
14 MA_141_142_A10-6-7-3-6-5_130617_en
4.3 Adjust stitch regulating bolt 137.0014 for stitch adjustm e nt
Eccentric (A) 353.0031 (Fig. 1) and bolt (B) 137.0014 (Fig. 4) have to be
adjusted to the specific stitch length required for each machine (See chart).
Make sure that wing 223.0045 and rod 120.0082 are correctly set. Bolt
137.0014 must be mounted with the grain mark facing upwards because this
mark indicates the stitch length; in other words, it moves - in direction of arrow to the right (-) when at its smallest, and to the left (+) when the longest stitch is
being formed. (Fig. 4 and Fig. 5)
4.4 Adjust needle- and feed motion
If the machine is set to produce the longest stitch (see chart), the feed motion
stops when the point of the needle placed approx. 1.5 mm within the cup edge
before penetrating the fabric.
The feed motion starts when the needle is placed approx. 1 mm behind the cup
edge.
Needle- and feed motion are adjusted at needle bar eccentric (E) (Fig. 1), note
the foremost needle position (table).
When adjusting the needle bar, make sure that the needle clamp device at the
needle bar head stands exactly rectangular to the rear feed cup.
Fig. 5
15 MA_141_142_A10-6-7-3-6-5_130617_en
4.5 Looper motion
The looper motion is determined by the stroke of the looper eccentric (F)
(Fig. 1 and Fig. 6), by the crank distance, and by the distance between drill
holes in the clamp lever. These parts are different for each machine class. The
looper motion must start and end at the same time as the needle bar motion.
The lateral looper movement is determined by the control cam and must be in
accordance with the needle motion.
The looper shaft must be mounted exactly in the center of the needle bar.
We recommend to fit the parts onto the shaft so that they can still be moved,
and to fasten them tightly only after the final adjustment.
4.5.1 Adjust the looper motion
Mark the upper dead point of needle bar eccentric (E) (Position 1).
Find and mark the top dead centre of the needle bar eccentric (equals position
"1"). (E)
The top dead centre of the needle bar eccentric is equal to the bottom dead
centre of the gripper eccentric offset by 180° (see chapter “4.5.2 Adjust the
looper eccentric (on single thread machines)”).
In this position, turn the control cam until the looper – moving to the right –
takes up the loop and reaches the turning point.
Make sure that a play of approx. 1 mm remains between control cam and
setting ring at the looper shaft, because a lateral displacement of the cam also
influences the looper movement.
If the distance is enlarged, the deflection of the gripper to the right is reduced.
The total path of the gripper hardly changes.
16 MA_141_142_A10-6-7-3-6-5_130617_en
Fig. 6
4.5.2 Adjust the looper eccentri c (on single thread m a c hines)
Set looper eccentric (in position 1) so that ist surface stands horizontally
(Fig. 6). For setting the needle in its utmost rear position, turn the hand wheel
about 100 degrees (position 2). In this position, the looper is set about 2 mm on
the left of and about 3 mm above the needle, but this varies according to stroke
of loop (Fig. 7a). When the needle has moved forth to the looper’s right hand
edge, its point moves past the looper approx. 1 mm above it (Fig. 7b). At the
utmost dead point of the looper’s lateral and longitudinal movement, the point
of the needle is at 1 to 3 mm within the feed cup, which depends on how the
stroke of loop had been adjusted.
4.5.3 Adjust the looper eccentri c (on two tr e a d m a c hines)
Set looper eccentric (in position 1) so that ist surface stands horizontally
(Fig. 6). For setting the needle in its utmost rear position, turn the hand wheel
about 100 degrees (position 2). In this position, the looper is placed in front of
and above the needle; the distance varies according to looper motion and
stroke of loop. (See chart)
When moving forth, the needle moves closely below the looper without actually
touching it (Fig. 8a) and takes up the thread from the looper’s groove. The
looper motion stops when the point of the needle reaches its center (Fig. 8b).
When the needle has taken up the thread and is about to penetrate the sewing
material (approx. 2 mm in front of the cup edge), the looper moves about
0.7 mm to the left, then past the sewing material to the front turning point
(stroke of loop) on the right. (See chart)

Fig. 7
a b
Fig. 8
4.5.4 Adjust the front crank
Set the front crank (131.0010, 131.0019, according to machine class) vertically
in position “1”.
The regulation of the front crank influences the looper’s upwards movement. In
its front position, the looper moves upwards, and should move very closely over
the needle (0.1 to 0.15 mm) to ensure that the loop is properly taken up. You
also have to consider the different needle sizes. In its utmost rear position, the
looper is placed below the needle, and the needle about 1 mm above the
looper’s bevelled edge. (Fig. 7b)
18 MA_141_142_A10-6-7-3-6-5_130617_en
4.5.5 Set the looper in its front position to the feed cup
The looper reaches its utmost front position on moving approx. 45 degrees
opposite to direction of sewing. To be set as per measures (H) – see chart. It is
important that the height of looper and shaft is properly adjusted. (See chart)
It has to be controlled if measure (L) consides with looper shaft set as
described at chart page 30 and 31, readjust, if necessary.
4.5.6 Adjust stroke of loop
Each machine requires a certain stroke of loop (B) (see chart), which is
regulated by turning the control cam and the looper eccentric; measured from
the needle’s front dead point to the point where the looper stands above the
center of the needle.
To obtain a large stroke of loop - turn cam and looper eccentric opposite
to the machine’s direction of sewing.
To reduce the stroke of loop - turn cam and looper eccentric in
direction of sewing.
Then the looper takes up the loop and puts it – as straight as possible –
backwards on the sewing material.
4.5.7 Adjust the front bearing bloc k
The height of the front bearing block (M) (Fig. 1 and Fig. 6) is specifically set for
each machine. The looper motion depends on the control cam and can be
altered as follows: To increase the looper motion to the right, put a distance
plate under the bearing block. To reduce it, take off the distance plate.
4.5.7.1 Basic dimensions f or front and rear be a ring block
Manufacturing constructs the machine housing to a certain dimension. To get to
a different basic dimension for the various sub-classes, spacer plates of the
required thickness are placed underneath the bearing block when necessary.
19 MA_141_142_A10-6-7-3-6-5_130617_en
4.5.8 Adjust the rear bearing block
The looper movement may be altered in the final positions by shifting the rear
bearing block (N) (Fig. 1 and Fig. 6). On its return movement, the looper gets
close to the needle in its vertical- and front position, without essentially
changing its height in the rear position. (Ratio approx. 10:1). When moving
forth, the distance between looper and needle increases.
4.6 Adjust height of rear feed cups
Fit bushings 150.0170 and 150.0281 so that the lower bushing is on a level with
the surface on which the free wheeling is screwed, that the bottom socket is
4 mm within the bolting surface for the free wheel; the top socket needs to
provide the distance for the transport plate. In the mounted state with the
transport shaft head the distance between needle shaft middle and transport
plate top edge is the measurement “a” from Fig. 6.
4.7 Mount the front f e e d cup
When mounting the front feed cup onto the machine, make sure to fix it
horizontally and 0.1 mm lower than the rear feed cup. If the machine is
equipped with a needle guard, the needle groove must be another 0.1 mm
below the upper edge of the front feed cup.
4.8 Length adjustment of bar 133.0851 between s t itch regulation rod and free wheeling
The distance between the two drill holes ∅6 must be 111 mm. (Fig. 5)
4.9 Thread lifting mechanism at needle bar head
Class 141: Adjust lifting bar 124.0053 so that the thread is lifted – on the
needle’s backwards movement – when the looper is placed vertically above the
needle and has taken up the loop. Then – while the needle moves forth – until
the looper’s point reaches the center of the needle. (Fig. 1)
The same applies to class 142. In other words, the thread must be loose
(without tension) from the moment the looper takes it up until the looper’s right
hand turning point. Make sure that thread clamping bolt 138.0081 at the needle
bar head releases the thread just about 0.3 mm. You should also consider that
threads vary according to machine class and application.
(Fig. 9)
The thread drag on the needle bar is 0.35 - 0.4 N.

4.11 Needle setting
Concerning the setting of the needle bar, refer to table containing setting data.
4.11.1 Adjusting needle height (Fig. 10 and Fig. 11)
A special device permits needle height adjustment, a feature particularly
advantageous if needles of different sizes are used. Turn the eccentric
132.0069, provided with a slit, and placed on front of the head of the needle
bar. Make sure that the needle of the respective thickness always goes with a
distance of about 0.1 mm over the transport plate. Loosen screw 171.0407 of
the needle set plate 285.0054 (or 285.0055, 285.0147, or 285.0159, different
depending on class), adjust height of needle and retighten screw 171.0407.

4.12 Chaniging the looper
The looper can be removed after loosening clamping screw 175.0403 (Cl. 14140/-50) (Fig. 12) and 172.0403 (Cl. 141-23/-30 and 142-30/-40) (Fig. 12a)
respectively, at looper shaft head.
Upon mounting a new looper, take care that it touches the needle neither in its
front position nor in its rear position. (Also refer to setting data)
The wide gripper back should be standing as parallel as possible to the needle.

4.13 Maintenance
Since the machines feature fully automatic lubrication, they need no
maintenance in this regard. Never the less, we would recommended an oil
change approx. every six months, which depends on how many hours the
machine is used per day, and on its degree of soiling. You should use approx.
¾ of a litre of oil with a viscosity of 46 cSt (Recommended oil: Shell Voltol 46)
4.14 General Data
All further informations – technical data, application and operating instructions –
are included in the manual we provide with each machine.

5 Notes on repair and a djustment
5.1 Transport plate assembly
Refer to the table for the transport and pressure plates needed for the various
classes.
In addition to the transport and pressure plates featured in the normal models,
optional transport and pressure plates with appropriate teeth and edge heights
are offered to handle various materials to be processed.
5.2 Exchanging the trans port plate
Exchanging the transport plate is done by loosening the screw 171.0609.
(Fig. 12)
If a pressure plate needs to be exchanged, loosen screw 171.0502, which
holds the whole plate set in the bearing arm. Make sure when inserting each
pressure plate that the edge of the pressure plate is always about 0.1 mm lower
than the edge of the transport plate so that the needle can move over the edge
of the pressure plate without hitting it. (Fig. 12)

5.3 Mounting and sett ing instructions for STROBEL gathering devic e No. 314.0399
(see operating instructions – Working instructions)
The gathering device EV (Fig. 14) is fixed to the machine housing by two
screws 171.0607. In the housing you will find two threads which are closed by
two blind screws if the EV is not used.
When mounting EV note, that, after swivelling down guide 186.0195, this must
stop abt. 1 mm below the cup edge and abt. 5 – 6 mm on the right side of the
needle.
When mounting the EV to a machine originally supplied without EV, drill a
24 dia. boring for rod 133.0286 in the table top, according to Fig. 13.
