True or False: The comb teeth must ride slightly above the top of the step treads.

The statement that the comb teeth must ride slightly above the top of the step treads is false. For safe and proper operation of an escalator, the comb teeth should not protrude above the step treads. They are designed to align with the step treads in such a way that they facilitate a smooth transition for passengers getting on and off the escalator. If the comb teeth were to ride above the tread surface, it could create a trip hazard and increase the risk of accidents, as users may catch their shoes on the teeth. This alignment is crucial for ensuring safety and maintaining the escalator's functional integrity. Therefore, the correct understanding is that the comb teeth should be positioned in a way that they complement the step treads, promoting a seamless experience for passengers.
