Figure 13-B: Front wheel adjustment.
1. Loosen, but do not remove, the screws (
A
-
C
-
D
) and nuts with two (2)
½ in. open-
end wrenches
and the screws (
B
) with a
5/32 in. hex wrench
(see Figure 13-A).
2. Pull or push on the fork bracket according to the required seat depth.
3. Adjust the depth of the fork bracket to the seat depth of the wheelchair. For
example, if the seat is 16 in. deep, the fork bracket must be adjusted accordingly
(see Figure 12).
4. When the bracket is in position, tighten the screws (
A
and
B
),
MAKING SURE
that
the screws are inserted all the way, so the lock washers are crushed. It is
recommended that screws be tightened to 80 in.-lbs. to avoid breaking the
wheelchair and the screws.
5. Next, move the front anchor so it is resting on the seat interface, then tighten the
screws (
C
) as required (see Figure 13-A).
6. Check that the rear wheel axle is in the required position (see Section 4.6.2), then
tighten the screws (
D
) as required (see Figures 13-A and 13-B).
7. Repeat the steps above to adjust the other side of the wheelchair. Check that the
fork bracket has the same front depth, and the frame has the same rear wheel
axle position (see Figure 13-B).
8. Also make sure that the front anchors are in the same location.
When the front wheels are adjusted, you must
readjust the rear wheel axle. See Section 4.6.2
