2. Loosen the two (2) nuts with two (2)
1 1/8 in. open-end wrenches
and
remove only one nut, the one on the inside of the wheelchair if you want to
narrow the width (see Figure 18-A), or the one on the outside if you want to
widen it (see Figure 18-B):
3. Unscrew the threaded spacer so that its outer face protrudes at least 1/8 in.

inside nut to increase the width;
4. Tighten the two (2) nuts to a torque of 30 lbs-ft.;
5. Fold one of the notches on each of the lock washers against one side of the
nut.
NOTE:
Do not overtighten, as this may break the spacer threads or the contour of the
nut.
NOTE:
This adjustment is for 20, 22 and 24 in. wheels only. It is not suitable for 12 in.
