The oil passes from the oil sump to the cavity in the sewing head
through the spiral grooves in the hook driving shaft 19 and through the
duct 7. The ch ec k v a l v e 9 , c o nt ai n ed i n t hi s d uct, avoids the oil

From here, the oil is conducted through the wicks to the articulations
of the foot lifting mechanism and to the rocker. The foot lifting
eccentric is lubricated by the wick 25, sucking the oil out of the cavity.

Oil supply from the machine head to the hook case
The oil splas h ed i n t he s ew i ng he ad is picked up b y th e f el t , p as s ing
the oil to the lower wick, which in turn delivers the oil to the hook case.
The oil dropping from the brass tube 4 into the cavity is collected by
the felt pla te 1, pa s s ing then via the duc t 2 0 t o t he ho ok c a s e.
Oil supply to the hook
The oil returned from the sewing head flows through the duct 32 into
the hook case. Here, the oil can rise up to the level of the suction
pipe 31.

passes thro ug h t he bo r e-h ol e 27 i nt o t he l ower vessel 34. The sm al l e r
portion of this oil is conveyed by centrifugal force through an oil pipe
35 to the hook race. The major part of the oil flows again down and
lubricates the gears 30 and the ball bearing 28.
Oil backflow from the hook case to the oil sump
The pump 18 on the hook driving shaft sucks the oil from the hook
case via the pipe 16 back to the oil sump.. The filter 14, contained in
this pipe, intercepts soil particles and avoids thus disturbances of the
pump functions. The pump 12 sucks the oil from the outer plastic tray
via the oil f el t 15 an d v i a th e d uc t 15 ..
2.10.3 Checking oil level and oil supply
Caution: Danger of bodily injuries !
The machine must be in the position "Safe motor stop ".
–
Check the oil level in the oil sump through the sight glass 10 while
the machine i s o ut of operation.
Top up if the oil level is in the lower third of the sight glass.
–
Check the oil s u pp l y to th e s e wi n g hea d t hr o ug h t he si gh t g l ass 5
while the sewing machine is in operation, e.g. during the automatic
cycle.
–
Check the oil level through the sight glass 17 of the hook case
when the latter is in the sewing position and the sewing machine is
out of opera ti o n.

to recognise the position of the small oil pipe.
–
By means of a s oc ket spanner, having an open i ng of 1.5 mm, turn
back the screw 1 until the small oil pipe 2 does no longer move.
Normally, said pipe will not move when it stands in the middle of
the bore-hole.
–
Tighten the screw 1 until the pipe begins to move.
–
Turn the screw agai n by 1 /8 rev o l ut i on .
The adjusted oil quantity will decrease with the increasing distance
of the pipe fro m the middle of th e b or e -hole.
–
By means of a socket spanner, turn the screw 1clockwise for
reducing the oil quantity.
Turn the screw 1 counter-clockwise for increasing the oil quantity.
Please note the following:
The adjustme nt r an ge be tw ee n the maximum and th e m i ni m um oi l
quantity corresponds to a quarter (1/4) revolution of the screw..
ATTENTION !
The small oil pipe will be squeezed if the screw 1 is turned-in
excessively.
