no weight on them, and may turn suddenly and without
warning if used as a step, resulting in serious injury.
• If lock cylinder is extended, perform a brief unfold
operation (Extend the Fold circuit) to retract the
lock cylinder.
• If the lock cylinder will not retract, perform a brief
Lift operation (Extend the Lift circuit) to free the
pawl. If this fails to disengage the lock, see “Lift
