Under normal working conditions, the PT 2500 E drive requires no special servicing. Parts
such as the motor brushes and bearings are subject to natural wear.
The following are standard values for wear parts of the drive:
Ball bearings: several 1000’s of operating hours.
Motor brushes: Approx. 150 hours of operating at rated power.
We strongly recommend that service work and repairs should be carried out only by
authorised KINEMATICA service centres or by KINEMATICA directly, where original
replacement parts are available.
Any unauthorised modification or manipulation of the unit or its equipment leads to
immediate annulment of the warranty.
