11.8 Cross Brace and Locking Link Assembly Fitting
Fit the two 1/4 UNF set screws securing the Cross Braces to each side frame.
Tighten until the Cross Brace is just securely held, then loosen the nut half a turn.
The Cross Brace Assembly must be free to move without binding, but show no signs of excessive
free play. Lubricate with light oil, eg 3 in 1. Overtightening of Cross Brace Assembly will prevent
the pivoting action and will lead to fracture of the tab on the side frame.

11.10 Inspection
Check Locking Links for security of thumb catch and correct operation. The locking link should
open/close easily and the thumb catch must hold securely in the open position so that the
powerchair will not fold under load.
Check each tab on the side frame for evidence of bending, elongation or worn holes, and cracks
in the brazing or tubing.
