concerned, without requiring any special attention by the operator. The blade

Blade guide plates
The plate contact points feature widia inserts which guide the blade longitudinal-
ly. A small amount of play must exist between the plates and blade to ensure that
the blade runs smoothly and perpendicular to the work table.
Thanks to the widia inserts, the working life of the guide plates is practically the
same as that of the machine itself. However, if due to wear or the assembly of a
new blade with a different thickness, the amount of play between the plates and
blade changes, the plates must be adjusted as follows:
"
disconnect the machine from the power supply;
"
slacken the blade tension using the handwheel;
