Troubleshooting guide

Malfunctions often have simple causes that you can
remedy yourself using the following overview. When in
doubt, or in the case of malfunctions not mentioned
here, please contact your authorised Customer Service.
As the battery pack ages, even if it is looked after, its ca-
pacity reduces such that the full run time will no longer
be reached when fully charged. This does not indicate a
defect.
Rectification
 Charge the battery pack.
 Replace the battery pack.
 Push the battery pack into the mounting
until it latches into place.
 Stop working and allow the battery to cool
down to normal battery temperature.
 Stop working and allow the motor to cool
down.
