ON“ button of the magneto thermal switch does not lock-in, check that the selector to release the brake is in the correct
position, or,when the star delta is fitted,check that the knob of the star delta starter is in “
O” position.
• The motor lacks electrical power: consult an electrician.
THE MACHINE DOES NOT WORK EFFICIENTLY DURING OPERATION

• Loose drive belts: follow the tightening procedure
DOES NOT CUT STRAIGHT

• Check the alignment of the rip fence
THE BLADE HAS CRACKS AT THE BASE OF THE TEETH
• Incorrect sharpening and consequent overheating, othervise incorrect setting of the teeth
• Incorrect blade thickness in relation to bandwheels diameter
• The bandwheel tyres are damaged or have incrustation deposits
• Badly aligned bandwheels: requires the intervention of a qualified technician
THE BLADE IS CRACKED AT THE BACK
• Excessive feed during cutting
• Imperfect weld alignment: eliminate badly welded part and repeat the weld
• The rear thruster of the blade guide is damaged
THE BLADE BREAKS AT THE WELD :
• Overheating of the blade during welding: remove the weak area and repeat the welding
• Cooling down the weld too quickly after welding, proceed as above
THE MACHINE STOPS WITH THE BLADE JAMMED INTO THE WORKPIECE

blade and its position on the bandwheels before recommencing

• The blade slips back at the beginning of cut: blade not sharpened or blade incorrect for material in work or there is a defect on
the crown of the bandwheel surface.
