Exchanging the upper blade
Attention!
Before changing the blade a, ALWAYS remove the
plug j from the mains power socket. This prevents
an unintended starting of the machine. If you do
not, you run a risk of serious injury!
Note:
The lower blade p is manufactured from a special
material and normally does not need to be exchanged.
Should it at some time become nonetheless damaged,
please make contact with our Customer Services.
To exchange the upper blade a when it has become
blunt:
1. Open the front flap 8 and turn the handwheel 6
towards yourself until the needles are in the lowest
position.
2. Using the screwdriver, loosen the screw on the
upper blade holder and remove the upper
blade a.
3. Insert a new upper blade a and lightly tighten
the screw on the blade holder.
4. Adjust the upper blade a to that its cutting edge
surmounts the cutting edge of the lower blade p
by about 0.5-1.0 mm.
5. Now firmly tighten the setscrew in the holder for
the upper blade a and close the front flap 8.
