Troubleshooting

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.
Defect
Rechargeable battery
empty, an LED on the rechargeable
battery is flashing.
Overload, machine switches off.
The machine switches off at a
sudden increase in load.
Danger
Determining the causes for existing defects and eliminating these always
requires increased attention and caution.
Cause
almost Electronic system protects the
rechargeable battery from deep
discharge.
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).
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.

Only one LED is still glowing.
Charge the rechargeable battery.
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.
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.
