MOTOR
Please note that the vacuum motor does not require lubrication. Each motor
contains two carbon brushes which will wear normally, and may eventually require
replacement. For warranty purposes, this should be done by an authorized service
center. Brush's life is affected by the number of hours used, frequency of start-ups
and shut-downs, humidity, altitude, and temperature. In order to avoid damage to
the motor itself, brushes should be replaced before they are completely worn out.
We therefore recommend that you have your unit and motors inspected by a service
center every 5 years.
