Inspecting and replacing carbon brushes
Warning! Unplug the machine before inspecting the carbon brushes.
The life expectancy of the brushes depends on how hard the motor has been run. The brushes should be
checked after 50 hours operation if the saw is new or if they have been replaced. They should then be checked
after every 10 hours operation.
Check the carbon brushes as follows:
1. Remove the covers (19) on each side of the motor.
2. Extract the carbon brushes.
3. Check their length (min 6 mm).
4. If either of the brushes is shorter than 6 mm or the spring is damaged, they must both be changed.
Troubleshooting guide - motor
• To prevent the motor from overheating it should be regularly air-blasted to remove any dust
or wood chips from clogging the air vents.
• Use the saw with an earthed power supply protected by a 10 A slow blow fuse.
• Release the on/off switch immediately if the motor does not start straight away. Pull out
the plug and make sure that the blade spins freely.
• If the motor stops in the middle of sawing: Release the on/off switch and pull out the plug.
Remove the blade from the workpiece, plug the saw in again and try starting the motor again.
• Check for loose connections, overloading (several devices on the same fuse circuit), cable core area
(1.5 mm² up to 7 m in length, or at least 2 mm² for 7–15 m cable) and length of cable (not over 15 m).
