1. Remove T-arm from wheelchair. Refer to INSTALLING/REMOVING T-ARMS in this
section of the manual.
2. Remove the phillips bolt and locknut that secure the EXISTING locking lever to the
bottom bracket.
The locking lever is spring loaded. Place your free hand over the locking
lever to prevent the parts from springing off of the bottom bracket,
otherwise parts may be lost or injury may occur.
3. Remove EXISTING locking lever and spring from bottom bracket.
NOTE: Inspect the spring for damage and replace if necessary.
4. Position spring on bottom bracket as shown in FIGURE 5.
5. Position NEW locking lever onto spring and bottom bracket (DETAIL "A").
NOTE: Make sure the two extended ends of the spring are inside the notch in the locking lever.
6. Line up the mounting holes in the NEW locking lever, spring and bottom bracket.
DO NOT overtighten locknut that secures locking lever to bottom
bracket. Overtightening this locknut will prevent locking lever from
operating properly, possibly causing injury.
