Question

you notice that your lift is starting to drift downward just a bit while in use. its very slow. what should you do?
ignore it. as long as you can service cars, it doesnt matter.
mention it to your manager, but keep using the lift.
stop using the lift and ask your supervisor to have a lift service technician come check it out.
attempt to troubleshoot it yourself.

Explanation:

When a lift shows signs of malfunction (even a slow drift), ignoring it (safety hazard) or continuing to use it (risk of further issues) is unsafe. Troubleshooting without proper training (risk of injury or worsening problem) is also wrong. Stopping use and getting a professional (lift service technician via supervisor) ensures safety and proper repair as they have expertise.

Answer:

Stop using the lift and ask your supervisor to have a lift service technician come check it out.
