Motor Brushes
The electric motors that power your power chair use car-
bon brushes. These brushes may become susceptible to
wear over a long period of time. The motor brushes are the
two contacts 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 be-
come 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 27.
2. Remove the brushes.
3. Inspect for wear. See figure 28.
4. Replace the brushes, if necessary. Contact your
authorized Pride Provider for replacement brushes.
