Page 15: Motor
6.3. Motor For DC motors it is necessary to change the carbon brushes after 2000 hours run. After that, clean the surrounding area thoroughly. For the rest, geared motors require no maintenance for 10,000 operating hours. Depending on dust accumulation, clean the motor fan cowl, the motor itself and the gearbox housing. This helps to ensure proper cooling of the motor. - Page 16 In order to make sure that your order is processed swiftly and correctly please specify the device type (see rating plate), the quantity required, the spare part designation and the spare part number.
