The following contains information about changing the position of the motors. Rear Position - Lengthens the wheelbase and gives the wheelchair the most stability and standard maneuverability. Middle Position - Centers the wheelbase and gives the wheelchair standard stability and maneuverability. Forward Position - Shortens the wheelbase and increases maneuverability and distributes additional weight on rear wheels. *NOTE: The forward mounting position is not available on Arrow wheelchairs equipped with GB motors. The following shows the positions of the screws into the gearbox: DETAIL "A" - MOTOR/GEARBOX WHEELCHAIRS Rear Position Approximately 65% of weight over drive wheels Middle Position Approximately 70% of weight over drive wheels Front Position Approximately 75% of weight over drive wheels DETAIL "B" - *GB WHEELCHAIRS Rear Position Approximately 65% of weight over drive wheels Middle Position Approximately 70% of weight over drive wheels Forward Position Not available with GB motors.
