6.8 Wheel Lock and Wheel Lock Release
Before working on the wheel lock release, turn off
the B500/B500-S power wheelchair. Secure the power wheelchair so it cannot roll away.
Only mount the wheel lock release while it is unlocked. Ensure that the short Bowden cable is at the
bottom. The Bowden cable for the left side passes in front of the drive unit sustainer.
The wheel lock release is located at the front right below the seat, on top of the frame cross brace.
