Where is the hand pump for raising the B-4 maintenance stand located?

The hand pump for raising the B-4 maintenance stand is located on the platform near the ladder. This placement is designed for user convenience, ensuring that the operator can easily access the pump while engaging with the stand. By having the pump near the ladder, it allows for efficient operation and minimizes the time needed to adjust the height of the maintenance stand, enhancing workflow and safety during maintenance tasks.

In the context of the other options, the base of the stand and beneath the platform would make it more cumbersome for users to operate the pump while also managing their positioning on the stand. Moreover, attaching the pump to the side of the frame might limit access when the stand is in use or obstruct the user's movement. The selected location on the platform near the ladder optimizes both functionality and safety in maintenance operations.
