7 Troubleshooting
Danger
Determining the causes for existing defects and eliminating these always
requires increased attention and caution.
To activate the electronic functions: Press the switch trigger (15).
If the machine switches off automatically, the electronic system has activated self-protection mode.
Despite this protective function, overload and as a consequence damage to the machine may occur during
certain applications.
Some of the most frequent defects and their causes are listed in the following chart. In case of other defects,
contact your dealer or the MAFELL customer service.

empty, an LED on the rechargeable
battery is flashing.
Electronic system protects the

Only one LED is still glowing.
Charge the rechargeable battery.
Overload, machine switches off.
A sustained load has overheated
the machine or the rechargeable
battery. A warning signal is
sounded (constant bleeping).
This sound stops after max. 30
seconds or when the switch
trigger is released (15).
Allow the machine and the
rechargeable battery to cool
down.
The rechargeable battery can be
cooled down much faster with a
charger with air cooling.
The machine can also be cooled
down much faster by using a
different rechargeable battery and
idling the machine.
The machine switches off at a
sudden increase in load.
The sudden increase in load also
causes the current that is
required for the machine to rise.
This rise in current, which occurs
when there is a sudden blockage
or backlash, is measured and
then leads to the machine being
switched off.
Switch off the machine by
releasing the switch trigger (15).
Afterwards, you can switch the
machine back on again and
resume work as normal.
Try to avoid further blockages.
