REMEDY

See “Material classification and blade
selection” in the

Blade running-in sec-

tion.
Turn teeth in correct direction.

Use a superior quality blade.
Decrease advance, exerting less cutting
pressure. Adjust the braking device.
Change speed and/or type of blade.
See chapter on “Material classification
and blade selection”, in the section
Blade selection table according to cutting
and feed speed.
Material surfaces can be oxidised or cov-
ered with impurities making them, at the
beginning of the cut, harder that the blade
itself, or have hardened areas or inclu-
sions inside the section due to produc-
tive agents used such as casting sand,
welding wastes, etc. Avoid cutting these
materials or in any case perform cutting
with extreme care, cleaning and remov-
ing such impurities as quickly as possi-
ble.
Check level of liquid in the tank. Increase
the flow of lubricating refrigerant, check-
ing that the hole and the liquid outlet pipe
are not blocked.
Check the emulsion percentage.

The welding of the blade is of utmost im-
portance. The meeting surfaces must
perfectly match and once they are welded
they must have no inclusions or bubbles;
the welded part must be perfectly smooth
and even. They must be evenly thick and
have no bulges that can cause dents or
instant breakage when sliding between
the blade guide pads.
Decrease advance, exerting less cutting
pressure. Adjust the braking device.
Change speed and/or type of blade.
See chapter on “Material classification
and blade selection”, in the section
Blade selection table according to cutting
and feed speed.
Choose a suitable blade. See Chapter
“Material classification and blade se-
lection”.
Check the gripping of the part.

At the beginning of the cutting process,
never lower the saw frame before start-
ing the blade motor.
