MOTOR BRUSHES

The electric motors that power your power chair use carbon brushes. These brushes may become susceptible to wear over a long period of time. The motor brushes are the two con- tacts located inside the motor assembly that supply power to the motor. They are designed to provide several thousand hours of operation. However, if the brushes become dirty with carbon deposits or wear out, the motor will run poorly or not at all.

To inspect or replace the motor brushes:

1.Unscrew the motor brush caps. See figure 33.

2.Remove the brushes.

3.Inspect for wear. See figure 34.

4.Replace brushes, if necessary. Contact your authorized Pride provider for replacement brushes.

CAUTION! If an inspection determines excessive wear on the brushes, they must be replaced or motor damage will result. Failure to maintain the brushes could void your power chair’s warranty.
