TROUBLESHOOTING
PROBLEM /
FAULT
PROBABLE CAUSE SUGGESTED REMEDY
The motor is not
working properly.
1. Faulty motor, power cable or
plug.
2. Blown fuses in the electrical
cabinet.
3. No voltage in the mains
system.
4. The motor’s thermal circuit
breaker has tripped.
1. Have the machine checked by expert
personnel.
DANGER - WARNING
NEVER ATTEMPT TO REPAIR
THE MOTOR YOURSELF: IT COULD BE
DANGEROUS.
2. Check the fuses and replace them
if necessary.
3. Check the mains power system is
present.
4. Release the start button and wait
for the thermal circuit breaker to
reset (a couple of minutes).
Intervention
of the thermal
protector
1. The motor has overheated.
2. Motor overload caused by
excessive cutting pressure.
3. Motor fault.
1. Check that motor ventilation air uptakes
are not clogged or obstructed.
2. Perform cutting by applying the right
pressure on the workpiece.
3. Have the motor checked by expert
personnel.
Imprecise
cutting angle at
0° - 45°.
1. Calibration of the stoppers (26) is
incorrect.
1. Perform calibration by slackening the
fi xing screws and repositioning the
stoppers.
Imprecision in the
squaring of cut
1. Excessive cutting pressure (on
tubes and profi les).

material being cut.
3. Cutting speed not right for the
workpiece being cut.
4. Incorrect adjustment of the
eccentric and sliding blade
guides. Incorrect positioning of
the workpiece in the clamp.
5. Poor blade tension
1. Reduce cutting pressure.
2. Check the cutting parameters in the
relative cutting chart.
3. Check adjustment of the blade guide.
4. Check the position of the workpiece and
that it is securely held in the clamp.
5. Check the blade tension.
The cutting
fi nish is rough or
uneven
1. The blade is worn down or the
teeth are not suitable for the
thickness of the material being
cut
2. Excessive cutting pressure.
1. Check the cutting parameters (blade
tooth, cutting speed) in the relative
cutting chart.
2. Reduce cutting pressure.
The blade tends
to jump out of the
guides
1. Excessive wear on the rubber
coating of the pulleys.
2. Slipping of the blade on the
pulleys.
1. Get the pulleys checked and if
necessary replaced, by expert
personnel.
2. Never use lubricants or coolants of
any kind. Get the pulleys checked
and if necessary replaced, by expert
personnel.
