Adjusting the Wheelbase Length
NOTE: For this procedure, refer to FIGURES 5.5, 5.6 a & 5.6 b.
1. Remove the wheel. Refer to Removing/Installing Rear Wheels paragraph.
2. Remove the (two or four) mounting screws that secure the top and bottom of the
axle plate to the wheelchair frame.
C A U T I O N
The top of the axle plate must remain on the plastic seat bracket.
Otherwise, scratching and slight frame damage may occur.
3. Align the axle plate with one of (two or four) adjustment holes. There are 2 positions
possible:
•
Factory setting for Fixed backrest is Standard position “A”, for Recliner backrest is
Passive position “B”. Refer to detail “A”, next page.
W A R N I N G
The (four or two) mounting screws need to be (four or two) adjustment holes apart
to maintain frame integrity.
Respect factory settings related to backrest type (Standard “A” for Fixed, Passive
“B” for Recliner), refer to FIGURES 5.6 a and 5.6 b.
Any change to one or any combination of the 2 positions may cause the
wheelchair to increase/decrease in stability.
Anti-tippers can be fitted to secure the stability if required. Refer to SECTION 9.
NOTE: When using the last adjustment position, the existing mounting screws needs to be
switched to the front of the back-cane bracket.

Repeat STEPS 1 to 3 for the other axle plate.
NOTE: Both axle plates should be set at the same position. Head of bottom mounting
screws needs to be on the outside position.
