Center of Gravity Adjustment
The most important adjustment on your Tsunami or Little Wave wheelchair is the position of the rear axle.
NOTE: Changes to the center of gravity may affect the rear seat height, toe-in/toe-out of the rear
wheels and the squareness of the casters. If you change your center of gravity position, readjust all
of these settings if necessary.
NOTE: Adjusting the chair’s center of gravity will require readjusting the location of the wheel locks
(if provided). Adjust the center of gravity by moving the two camber mount clamps (B) forward or
rearward on the seat tube (A).
Moving the camber mount clamps forward shortens the wheelbase and lightens the front end, making your
chair more maneuverable. Moving the camber mounts rearward makes the chair more stable and less
likely to tip over rearward.
1. To adjust the center of gravity location, remove both rear wheels.
2. Remove the screws (C) and nuts (A) that secure the camber mounts (B) to the seat tubes.
3. Slide the camber mount forward or rearward along the seat tube to the desired hole location. Reinstall
screws and nuts. In some cases where the attaching bolts also go through the backrest plate, longer
bolts are required (Tsunami image below shows an example).
4. Repeat on the other side. Ensure both sides are set in the same configuration.
