I always run my Femi bandsaw dry, it’s what it says in the manual.

I’ve got essentially the same saw. In four or five years of use I’ve never used any lube.

The saw is designed to be run without cutting lube. If you start spraying lube on things the drive belts won’t grip the sides of the blade properly and the chips may start to accumulate inside the housing in an unhelpful pasty mush that will not aid performance.

I have a Femi that I mostly use dry, and a small hobby (“wood”) Dewalt that I use for cutting sheet steel. The latter definitely benefits from lube such as a wax stick. However, it is all too easy to overdo the amount, and what I do is to apply a thin smear to the work along the cutting line. This seems to be enough to help keep the blade sharp, yet not enough to end up on the pulleys etc.

I use the same technique on anything particularly difficult on the Femi, just a trace along the blade path.

I have a small bandsaw, like a Femi and use a wax stick to lubricate the blade. It is in a big stick about 70mm dia and I just run the blade thru the end before cutting metal. The wax is also good for lubricating hand saws for cutting wood. The saw and the stick are about 7 years old and the wax does not cause the band to slip on the rubber drive wheel.

I use bi-metal blades on my saw. They cost a little extra but last way longer than standard carbon steel blades.

I have also run my bandsaw dry but it cuts better with a little lube, less friction and the blade lasts longer.

As I have already said, the drive wheels on my bandsaw have rubber rims and they have not slipped in 7 years while using wax lubricant. Oil would be different.
