Operation
Maintenance and Cleaning
Always unplug the impact drill before maintaining it.
Before each use ensure that the ventilation slots are open and clean.
Never clean the impact drill with water. Use a soft cloth to clean the
housing. Do not use aggressive chemicals or solvents to clean the machine
as these may damage the surfaces.
An extra pair of carbon brushes (14) is provided with this impact drill. If the
machine works powerlessly and sparking occurs at the brushes, it may be
a sign that the carbon brushes are worn and have to be replaced. Only
have the carbon brushes replaced by a professional or return the unit to the
Westfalia customer service department. Do not open the housing. Do not
try to repair it yourself.
If the keyed drill chuck became damaged, do not try to repair it yourself.
Have it replaced by a professional only or contact the Westfalia customer
service.
