Maintenance and cleaning
Carbon brushes
The carbon brushes may wear down to the white marking. Replace carbon brushes with spare brushes from
WALTER only. Using other carbon brushes results in loss of warranty. The carbon brushes may be ordered
from WALTER.
You can observe the brush sparks via the air slits. Turn the machine off immediately if the sparks are too
strong. To prevent further significant dam-age we advise sending the machine to our authorized service
centers for repair.
Cleaning
Ensure that the machine and the ventilation slots are always kept clean so you can work efficiently and safely. In
extreme working conditions, such as finishing metals, conductive dust can collect inside the machine. In that
case we advise the regular use of a compressor to clean the ventilation slits. Also use a grounded switch in the
electric connection.
