Caution! Danger of injury!
Switch off the main switch! Before starting the setting
operation, wait until the motor stops!
The dismantling operation is to be done in the position – trimming
mechanism out of function.
- Remove the knife guard (1) and screw in anew its attachment screw.
- Loosen the screw (2) and remove the complete holder (3) together
with the trimming knife (4) from the shaft (5). The sleeve (6) is to
remain on the shaft – it serves for orienting the position of the knife
holder when remounting.
Caution :
Be sure in placing the dismantled component parts into the drawer
with regard to the protection of the trimming knife cutting edge and to
the possibility of injury.

Lifting the top roller by electromagnet
6.1 Description
The core of the electromagnet, respectively its pin must be set in such
a way that the presser foot lifting is enabled.
6.2 Setting the electromagnet pin
Caution! Danger of injury!
Switch off the main switch! Before starting the setting
operation, wait until the motor stops!
- Unscrew the cap of the core (1) of the electromagnet.
- Shift the core (2) with the pin (3) and unscrew the locking screw (4).
- Unscrew the pin (3) in the core (2) in the “A” direction up to the
stop.
- Push the core (2) into the magnet (5) in the “B” direction up to the
stop.
- In this position, set the maximum top roller lifting in the “B” direction.
- Screw on and tighten the arresting screw (4).
- Screw on the cap (1).
6.3 Setting the electromagnet current
The time response of the current of electromag. has 2 phases:
- initial switching on (0,2 ÷ 0,5 s) - the maximum force
- maintaining (when keying)
It is necessary to set max. 40 % of keying (see instructions
for use of the stopmotor). With a higher value thereof
and with a long period of the presser foot in its lifted
position there is a danger of electromagnet overheating.
6.4 Aseembly of the top roller lifting
electromagnet
Caution! Danger of injury!
Switch off the main switch! Before starting the setting
operation, wait until the motor stops!
- Remove the rear guard (3).
- Using the screws (1),fasten the electromagnet(2) on the rear guard(3)
with the given orientation of the outlet cable(4).
- Mount the rear guard (3).
- Connect the outlet cable (see par. 8).
- Set the pin of the electromaghet (see par. 6.2).
