3.7. Troubleshooting the electric motor
The machine with electric motor has a LED for troubleshooting. The LED permanently
lit means that the machine power is limited to prevent the motor from overheating as
a result of continuous overloading for extended periods.
Rapid flashing means that the safety circuit prevents the machine from starting
automatically when electrical power is restored after a power failure. To start the
machine is such a case, switch the motor off and on again.
Slow flashing means that the carbon brushes are almost completely worn, which
results in the motor shutting off automatically. The brushes must be replaced with
new ones by the manufacturer of the electric motor.
3.8. Troubleshooting the cordless electric motor
The machine with cordless electric motor has a protection system that automatically
shuts off the motor when it is continuously overloaded for extended periods. To stop
the beeping signal that sounds in such a case, release the ON/OFF switch. If the
motor or battery feels very warm, wait until it cools before proceeding.
The motor can also shut off automatically if the machine jams in the workpiece.
To continue operation, release the ON/OFF switch and press it again. Avoid repeated
jamming in the workpiece.
Flashing of the LED means that the battery is almost completely discharged.
To see the charge level, press the LED activation button and check the LED. If the
battery is discharged completely, charge the battery or replace to a fully charged.
