Chair Measurement References
The Tsunami and Little Wave wheelchairs are capable of many adjustments to configure the chair to the
user’s needs. See the diagram below for terms that are commonly used during the process of adjusting the
chairs.

A. Seat Width (see diagram 1)
Measured from outside of frame tube on one side to the
outside of frame tube on the other side.
B. Seat Depth (see diagram 3)
Measured from front of back posts to front edge of seat sling.
Seat sling starts at beginning of bend at front of frame.
C. Sling Position (see diagram 2)
In Performance Position (0”), sling is at front of frame to keep
chair shorter and more maneuverable. The 1” or 2” seat sling
position extends the frame in front of the sling by that amount.
Adding more frame can improve stability and provide support
to aid in transfers.
D. Front Frame Bend (see diagram 3)
Angle between front seat tube and ground.
E. Footrest Taper (see diagram 1)
Indicates bend of front frame creating footrest. Taper is
measured from outside of seat frame to outside of front tube.
F. Front Seat Height (see diagram 1)
Measured from floor to top of seat tube at front of seat sling.
G. Footrest Width (see diagram 1)
Measured from inside of front tube to inside of front tube on
other side. Footrest width is listed below for each seat width
and taper.

Caster Mount
NOTE: The footrest tube must be removed prior to installation to allow the caster mount to slide
onto the chair frame.
1. Install the two end caps (G & I) and two bearings (J) into the caster housing (H).
2. Install the caster housing assembly into the caster mount (B) and secure with three bolts (E & F) using a
4mm Allen wrench.
3. Install the caster mount assembly onto the chair frame and secure by installing the four bolts (A, C & D)
through the caster mount and chair frame holes using a 4mm and a 5mm Allen wrench.
NOTE: There are three different sizes of the caster housing available - standard, extended and tall.
Caster housing size is dependent on caster size, front seat height and footplate selection. If
additional help is needed regarding caster housing size please contact Ki Mobility customer
service.

Frog Legs Ultra Sport Fork Polymer Replacement
NOTE: The Ultra Sport fork has different polymers that can be used based on the chair user’s weight
and preferred ride. The Phase 2 fork has one polymer that works for any configuration. If ever
needed, the replacement procedure is the same for a Phase 2, but no coin is needed.
1. Remove the pivot pin screw (D) using a 4mm Allen wrench.
2. Use a punch or small screwdriver and a rubber mallet to push the pivot pin (A) out.
3. Open the fork assembly and remove the polymer (C) and coin (B).
4. Install the new polymer (C) and coin (B).
5. Insert the pivot pin (A) back into the fork assembly. A punch or small screwdriver can be used to help
align holes if needed.
6. Secure the assembly by reinstalling the pivot pin screw (D) using a 4mm Allen wrench.
7. Repeat steps on opposite side.

Caster Angle and Squaring
To maintain optimal performance of your Tsunami and Little Wave, the front caster housing should always
be aligned perpendicular to the ground. Your chair is shipped aligned. It is recommended that caster
squareness is checked after making adjustments to the chair configuration related to any of the following
items: caster size or type, camber, rear wheel, tire, center of gravity and seat heights. Caster squareness
should always be the last check made prior to use after adjustments or changes to the chair have been
made.
After all other adjustments are made you should check your caster housing alignment and realign if the
housing is not perpendicular to the ground.
NOTE: A hole has been drilled in the caster housing to ensure squareness. This hole helps keep the
caster square, but it does allow adjustment of up to 4° in the case that the caster needs to be
resquared. See instructions below.
Adjusting the Caster Angle:
For optimum performance, the caster housing should always be at 90° angle to the floor (perpendicular to
the ground).
1. To change the angle, place the chair on a flat surface (such as a table).
2. Loosen the two 5mm Allen screws on the top of the caster housing clamp. This will allow the caster
pivot tube to rotate freely (A).
3. Loosen the one screw (B) underneath the housing clamp using a 4mm Allen wrench.
4. Place a large right triangle against the table surface and the front surface of the caster bearing housing.
This will align the caster stem rotational axis perpendicular to the floor surface.
5. When the alignment is correct, retighten the two 5mm retaining screws to 80 in/lbs.
6. Tighten screws in a balanced fashion - tighten one screw to 50 in/lbs and then the second to 50 in/lbs.
Return to the first screw and tighten to 80 in/lbs and then tighten last screw to 80 in/lbs. Repeat on
opposite side.
7. Retighten the one screw underneath the housing clamp using a 4mm Allen wrench.

the holes that provide the desired seat depth.
NOTE: One long bolt (65mm) and one oval top nut are used in the attaching of the camber mount
and back plate. See the image below for the location of those two pieces of hardware.
4. Repeat steps on opposite side.
NOTE: Ensure both sides of chair have the camber mount and back plate mounted in the same
configuration.

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.
