SUGGESTED REMEDY
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).
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.
1. Perform calibration by slackening the
fi xing screws and repositioning the
stoppers.
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.
1. Check the cutting parameters (blade
tooth, cutting speed) in the relative
cutting chart.
2. Reduce cutting pressure.
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.
