There is no doubt that a forklift driver requires a degree of training if a start up checkist is asking them to check mechanical items such as oil and coolant levels and any system manual or automated needs management.

If the system installed however insists that individual questions are answered and immediate results are given via say an email to management then the seat and the seat belt would probably be fixed by now. If not, then at least the reponsibility to resolve the problem is with someone who probably has the authority to order the replacement parts rather than still with the forklift driver.
