8.1 Setting the cutting gap tolerance

The cutting gap is adjusted after initial commissioning 
and after each knife change. 

-  If the cutting gap is set too large, the notching 

process may result in burr and chip formation. If the 
cutting gap is set too small, the knives may be da-
maged and the stroke may block. 

- Perform a few test cuts after adjusting the cutting 

gap.

Step 1: Disconnect the power supply.

Step 2: Unscrew the screws (Pos. 2, Fig. 13) then re-

move the safety cover (Pos. 1, Fig. 13).

Step 3: Loose the bias screws (Pos. 4, Fig. 13) and 

blade screws (Pos. 5, Fig. 13).

Step 4: Measure the tolerance by 0.25 mm thickness 

gauge (Pos. 6, Fig. 13).

Step 5: Adjust the upper and lower blades against to the 

thickness gauge. The thickness gauge should 
be nower removed smoothly.

Step 6: Tight all the screws.

ATTENTION!

Settings on mechanically acting machine  elements 
may only be carried out on the machine by trained 
specialists or specially trained and instructed per-
sons.

DANGER!

Incorrect mechanical settings can influence the 
safety of the machine to such an extent that it cau-
ses a permanent danger. Careless behaviour can   
put the personnel and the machine at risk when swit-
ching-on again.
-  Before making any mechanical adjustments, al-

ways switch off the machine at the main switch and 
secure the main switch against accidental restar-
ting, e.g. by attaching a warning sign.

-  After carrying out the adjustment activities, make 

sure that all covers and protective devices have 
been properly mounted on the machine again. 

-  Do not leave any tools accidentally inserted during 

setting activities. Before switching on the machine 
again, make sure that all setting tools have actually 
been removed. Make sure that no tools are left in-
side the machine, especially in the working area of 
the machine mechanics.

ATTENTION!

There is a risk that the machine will be damaged if 
the cutting gap is set incorrectly.

Use protective gloves!

ATTENTION!

No adjustment of the cutting gap is required for dif-
ferent sheet thicknesses. There are spring plates in 
the system which automatically adjust the cutting 
gap.
