are to be disconnected first, the fastening screws unscrewed
and, thereafter, the post is removed.
Caution ! Danger of injury!
Switch off the main switch! Before starting the setting
operation, wait until the motor stops!
- Unscrew the screw (2).
- Push the lubricating tube (3) downwards into the post.
- Disconnect the hose (4) with the wick.
- Loosen only one screw (5).
- Unscrew the screws (6).
- Shift the post in the sense of the arrows and remove it out from
the machine.

3.2 Needle and thread mechanism
3.2.1 Description
The take-up lever (1) is mounted in ball bearings, both at the spot
of its suspending on the connecting rod (2) and in the mounting
on the loop (12). The take-up lever is of aluminum and is provided
with a stuck-in eye for two threads. The connecting rod (2) is
mounted on the eccentric pin (3), by means of which the thread
mechanism is adjusted for a big or a small hook. The needle
bar holder (4) is mounted through the pin (5) in a rotating way
in the arm (6). In its top part, the holder is guided by the guide
pin (7). The movement for the needle feed is given to it by the
connecting rod (8) driven by the feeding shaft (9). The
connecting rod (8) is mounted by eccentric pin (13) with
needle bar hoder (4).
The connecting rod (10) of the needle bar (11) on the loop (12) is
mounted in a ball bearing and it is slidingly mounted on the needle
bar carrier. The mechanism is lubricated by means of a central-
wick lubricating system.
3.2.2 To check the handwheel angular adjustment
The handwheel (5) must be situated in its precise position
relative to the needle and thread mechanism. This position is
given by a pin (2), which locks the connecting rod of the
needle rod (1) through a hole in the arm (3). In this position,
the indicator (6) of the handwheel must show „O“. The position
is fixed by the handwheel screw (4) contacting a small flat
surface provided on the upper shaft.
The correct adjustment of the angular position has been car-
ried out at the producer‘s.
Caution ! Danger of injury!
Switch off the main switch! Before starting the setting
operation, wait until the motor stops!
