Troubleshooting
Overload protection
• The load speed drops sharply.
— The motor temperature is too high!
▸
Allow the machine to run at idle speed until it has
cooled down.
• The load speed drops slightly.
— The machine is being overloaded.
▸
Continue to work with a reduced load.
Safety cut-off:
• The machine was switched off automatically.
— The machine is switched off in the event of an
excessive current increase rate
(such as can occur e.g. in the event of sudden
jamming or a recoil).
▸
Switch off the machine at the trigger switch [1].
▸
Then switch on again and continue to work
normally.
▸
Avoid further jamming.
Restarting protection
• Machine not running.
— The restart protection device has tripped. If the
mains plug is inserted with the machine switched
on, or if the power supply is restored after an
interruption, the machine does not start.
