The service indicator lights and the drive
unit may be inoperative
– The saw has been in operation for at least 200 hours.
The drive unit and control panel must be returned for
servicing as soon as possible in order to prevent dam-
age.
– The saw has been in operation for 250 hours and the
safety cut-out has been activated in order to prevent
serious damage.
The ground fault circuit interrupter has been
tripped
Insulation fault

circuit interrupter’s tripping value
– Disconnect other appliances from the mains supply
used (especially those with an HF electric drive).
