Question

when should you use \braking\ to stop the lift truck?
when you want to stop the lift truck in an emergency.
when you have a load elevated.
when you want to stop smoothly and gradually.
when you leave the lift truck parked on a ramp or incline.

Explanation:

Braking in an emergency is a key safety - related operation for lift trucks. When there is an emergency situation, using braking is necessary to stop the lift truck immediately to prevent accidents. Elevating a load requires careful handling rather than just braking for stopping. Stopping smoothly and gradually might involve other control methods rather than just braking in the sense of an emergency stop. Leaving the lift truck parked on a ramp or incline may require setting the parking brake or other proper parking procedures rather than just general braking for stopping.

Answer:

When you want to stop the lift truck in an emergency.
