7.3 Saw blade replacement/tension

7.4 Tilting the table

Fig. 7-4: Tilt

The machine working table can be tilted up to an angle 

from -5° (N4400: -10°) up to +45°.

Adjusting the angle:

To tilt, remove the table padding to enable the saw belt 

to move through the table unimpeded. Open the clam-

ping screw with the supplied spanner and tilt the table to 

the desired angle, which is displayed on the mitre scale. 

Tighten the clamping screw again. 

Tilt -5° or -10°:

• Swing away the stop

• Adjusting the angle

To tilt the table back to its normal position, loosen the 

clamping screw once again and tilt the table up to the 

stop in the 0° position and clamp it in that position.

(Swing back the stop)

rection of the cut!).

 

Release the clamping lever and set the saw blade 

track using the hand wheel:

5.

  Turn the wheels manually and ensure that the saw 

belt glides properly around the wheels and does not 

collide with any solid machine parts.

Check the saw blade tension and if required, adjust 

with the hand wheel. The values refer to the saw bla-

de width.
