DANGER!
Before performing any tasks after a failure:
- Switch off the machine.
- Remove the plug from the socket.
- Wait for the saw blade to stop.
After any intervention, replace all safety devices and check them.
The engine does not work
A possible tension reduction has made the minimum voltage relay start.
- Re-start the machine.
There is not any supply voltage:
- Check the cable, the socket and the switch.
Saw blade moves away the cutting line or decentralizes itself
The saw blade is not centred on the driving wheel:
- Modify the upper flywheel inclination (see par. “Adjustment knob”).
The saw blade has broken
Saw blade tension is unsuitable:
- Adjust saw blade’s tension (see par. “Saw blade tension”).
The forcing is too high:
- Reduce the pressure exerting against the saw blade.
The saw blade is inadequate:
- Change the saw blade (see par. “Replacement of the blade”):
If you must cut a thin workpiece, you must use a thin saw blade.
If you must cut a wide workpiece, you must use a wide saw blade.
The saw blade is misshapen
The forcing is too high:
- Do not force sideways on the saw blade.
The saw blade stops
The forcing is too high:
- Reduce the pressure you are exerting on the workpiece.
- Check the sharpness and the kind of blade.
Machine vibrations:
Insufficient fastening:
- Firmly fasten the bandsaw to the ground (see par. “bandsaw fastening”)
The workbench is loose:
- Place the workbench and fix it. (see par. “assembly of the workbench”)
The motor is loose:
- Check the lock screws and tighten them if necessary.
The aspiration coupling is obstructed
No dust collection device is connected or the aspiration leg is too small.
- Connect the dust collection device or increase aspiration power (air speed
≥
20 m/sec
at the degree of the dust collection coupling).
