The motor does not start
• Check that the fly-wheel doors are correctly closed, otherwise the safety switch will not allow operation.
• Check that the emergency button, when fitted, is released.
• If the “ON“ button of the magneto thermal switch does not lock-in, 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
• Incorrect connection of the motor: consult an electrician.
• Loose drive belts: follow the tightening procedure.
Does not cut straight
• Check the sharpness and setting of the blade
• Check the alignment of the rip fence
The blade has cracks at the base of the teeth
• Incorrect sharpening and consequent overheating, otherwise incorrect setting of the teeth.
• Incorrect blade thickness in relation to bandwheels diameter.
• The band wheel tyres are damaged or have incrustation deposits.
• Badly aligned bandwheels: requires correction by 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
• Stop the motor and release the brake, widen the cut using a wedge to aid removing the workpiece, after this operation check the
blade and its position on the bandwheels before recommencing.
Other problems
• The blade moves backwards and forwards: weld misaligned.
• 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 band wheel surface.
