Perfection hoist on 1954 4100

Hi folks - need a little help with what the hoist should sound like! The link is for a video of the hoist running - a couple folks on Facebook thought the hoist is making a bad sound. I have no real idea of what it should sound like. I've been around some much larger hydraulic pumps (much louder), and have a brother in law with a fleet of modern dump trucks (also loud). So my initial thoughts were that it sounded ok. Now I'm not sure, and of course do not want to hurt anything. Also, I do not use the hoist often at all.

So if you have an idea of what it should sound like, and don't mind giving it a listen, I would appreciate any feedback.

Thanks
