Apart from the operator, who else may need to use the machine's operator's manual?

The correct answer highlights the importance of the operator's manual for maintenance staff. Maintenance personnel require access to the operator's manual to understand the proper functioning, servicing routines, and troubleshooting procedures of the forward tipping dumper. This knowledge is essential for them to perform preventive maintenance, conduct repairs, and ensure the machine is operating efficiently and safely. Familiarity with the manual allows maintenance staff to follow manufacturer recommendations and adhere to safety standards, thereby reducing the risk of equipment failure or accidents on site.

While safety inspectors, site visitors, and engineers may find the manual useful for various reasons, it primarily serves the maintenance team directly responsible for the upkeep of the machinery. Safety inspectors might reference it for compliance checks, site visitors may only need basic operational information, and engineers might consult it for design-related queries, but maintenance staff will utilize it extensively to carry out their duties effectively.
