Quantum Blast
MOTOR BRUSHES
The electric motors that power your Blast use carbon 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 become dirty with carbon deposits
or wear out, the motor will run poorly or not at all. If inspection determines excessive wear on the brushes, they must be
replaced or motor damage will result.
NOTE: Failure to maintain the brushes could void your Blast's warranty.
To inspect or replace the motor brushes:
1.
Remove the seat and batteries.
2.
Unscrew the motor brush caps.
3.
Remove the brushes.
4.
Inspect for wear.
5.
Replace brushes, if necessary. Contact your authorised Pride provider for replacement brushes.

ONTROLLER
The standard electronics is the Remote Plus controller system. The Remote Plus controller system consists of the keypad
and the controller box. The keypad sends signals to the controller box through a cable that is attached to the back of the
joystick and to the controller, through a connector on the power base. The Remote Plus keypad is typically located at the end
of either the right or the left armrest. The Remote Plus controller box is located underneath the front of the power base. If your
Quantum Blast is equipped with a different controller, refer to the owner’s manual that accompanied that controller.
JOYSTICK FUNCTIONS
The joystick controls the direction and speed of the power chair. See figure 9 and 10. When you move the joystick from the
neutral (center) position, the electromagnetic brakes release and allow the power chair to move. The further you push the
joystick from its neutral position, the faster your Blast moves. When you release the joystick and allow it to return to the neutral
position, you engage the electromagnetic brakes. This causes the chair to decelerate and come to a complete stop. If your
Blast begins to move in an unexpected manner, immediately release the joystick. Unless the joystick is damaged, this action
should stop your Blast.
WARNING! Use the on/off key to stop your chair in an emergency only.
