Verifying the Stability Lock Setting
NOTE: For this procedure, refer to FIGURE 10.
1. Ensure all six wheels are on a flat, level surface.
NOTE: A United States penny may be used to gauge the distance between the elevator bolt and the
pivot ball.
2. Insert the 1/16-inch gauge between the elevator bolt and pivot ball of both locking
cylinders (one on each side of the wheelchair) to ensure there is a 1/16-inch gap
between the elevator bolts and the pivot balls.
3. If necessary, adjust elevator bolt as necessary to achieve 1/16-inch clearance. Refer to
Adjusting the Stability Lock Setting on page 26.
4. Compress rear springs several times by pulling down on back canes or kneeling in seat
and pushing on the back canes to ensure the setting will not change after adjustment.
5. Repeat STEP 3 to verify that 1/16-inch clearance setting has not changed.
6. If 1/16-inch clearance has changed, repeat STEPS 4-6 to reset clearance.
7. Check the Stability lock function. Refer to Checking Stability Lock Function on
page 27.
