Inspect the carbon brushes
The motor contains carbon brushes that are consumable parts.
Excessively worn carbon brushes can result in motor malfunction.
Replace worn brushes with identical parts when they are worn near the
acceptable limit. Always keep carbon brushes clean and ensure that
they slide freely in the brush holder.
WARNING!
A carbon brush set is included in this package for
replacement purposes. Only a qualified service technician using identical
parts to ensure the integrity of the double insulation should perform the
check and replacement of brushes. To assure the safety of customers, we
strongly recommend the use of professionals to check and change brushes.
Note:
under normal usage, the carbon brushes will last longer than the
90 days warranty period. Therefore, do not open the body housing
within 90 days of purchase to inspect the brushes. Doing so will void the
warranty.
