CARE AND MAINTENANCE
CAUTION! If inspection determines excessive wear on the brushes, they must be replaced or motor damage
will result. Failure to maintain the brushes could void your warranty.
To inspect or replace the motor brushes:
1. Disassemble the power chair.
2. Unscrew the two screws that hold down each shroud piece.
3. Unscrew the motor brush caps. See figure 28.
4. Remove the brushes.
5. Inspect the brushes for wear. See figure 29.

CORRECTIVE MAINTENANCE
If the battery condition meter does not light up when you turn on the power:
l Check the harness connections. Make sure they are tight.
l Check the circuit breaker. Reset it if necessary.
l Check the battery connections.
If the above conditions prove normal, you can load test the batteries with a battery load tester. These testers are available at
automotive parts stores. Disconnect both batteries before load testing, and follow the directions that came with the load tester.
If either one of the batteries fails the load test, replace both of them. If your Quantum Dynamo ATS still does not power up,
contact your authorized Pride provider.
