Form of tooth cavity large enough compared to the pitch.

A quick removal of the cut material and a correct depth and rounding of the tooth

cavity are of the outmost importance. The tooth cavity must be large enough for the

removed chips to be bend as long as the tooth is cutting. When the cutting tooth

leaves the saw cut, the chip drops out of the tooth cavity.

The alternate saw (alternately bevelled edge) is often used for small pitches,

especially up to 4 mm.

The precutting and finishing teeth are used for larger, solid material, usually from

pitch 4 mm onwards. These teeth ensure that the chips are not all of the same length.

If a chip were to be cut out the normal way, it would get hot, expand and become

wider than the width of the cut. This would cause it to get stuck, as a result of which

the chip could not be removed from the cut. The finishing tooth must be positioned

0.2 to 0.4 mm higher than the precutting tooth. The larger the pitch, the higher the

precutting tooth must be placed as compared to the finishing tooth.

Consequently, only special machines are suitable for regrinding these teeth. When

the blade has lost its cutting power, do not strain it. As a result the teeth may break

off, which doubles the regrinding costs.

5.3 Sawing Capacity

For the maximum capacity in mm see the schedule for the profile

figure/cross-cut in relationship with the miter angle. Write 90º we mean straight

sawing.

5.4 Installing and replacing the saw blade

• Set the main switch in the off position.

• Put the saw head in the upper position.

• Open the guards

• Release the socket head screw M8 of the saw spindle and remove the saw
