Removing the Scissor Lock Spring
I
WARNING
When the scissor lock is disassembled, the spring will likely pop out forcefully. Therefore, you must wear eye
protection.
If you ignore this Warning, you could sustain a serious eye or other injury.
Tools Needed:
• 1/8” Allen Wrench
• 7/16” Open End Wrench
Some wheelchair users may not have sufficient arm strength to operate the composite scissor lock due to the tension
in the spring mechanism. You can remove the spring to facilitate easier operation of the lock. Removal of the spring
does not affect the lock’s ability to secure the rear wheel when fully engaged.
Note: Once removed, a special installation tool is required to reinstall the spring. If you require the re-installation tool,
contact TiLite Customer Service.
To remove the spring:
1. Remove the Allen Screw that connects the handle to the base. See Figure 10-12. Carefully note the order of the
washers above and below the handle.
2. Remove the nut that connects the wheel stop to the base. See Figure 10-13. Carefully note the order of the
washers between the nut and base.
3. Carefully separate the locking mechanism (handle and wheel stop) portion of the scissor lock from the base.
4. Remove and set aside the spring and metal washer shown in Figure 10-13.
5. Replace the spring and washer shown in Figure 10-13 with the black plastic washer that shipped with your
wheelchair.
6. Reattach the locking mechanism (handle and wheel stop) portion of the scissor lock to the base by inserting the
hex bolt through the black plastic washer (instead of the metal washer and spring), the base, and the two washers
and nut removed in Step 2.
