Am I safe to vacuum purge without a guage?

Just like the title says. I made a vacuum setup but can only find the gauges online, I'm ready to purge a few grams though. Never done it before, am I safe to run it without knowing what the vac pressure is?
The pump is a 2.5 cfm and pulls to 75 microns, 1 stage.
The jar is 5.5 inches around and 6.5 tall, I'm a little nervous with all the implode talk.
Roughly how long do you think I'll need to purge for?
Product was rosin and then winterized with ethonol.

Appreciate any help!

Purge until no more cavatition (bubbles). Stop vac, release pressure. Seal and pull vac again. Do this a couple times until no more bubbles.

Done

The gauge is not what makes it work, it just tells you what is happening.

I watch the product, not the gauge, to determine my progress, but I tell from the gauge that my system is actually reaching the vacuum levels that the pump is capable of.

The guage is just so you don't overshoot and boil off the terps, too.

If you're worried about implosion of the jar, run it a few times empty.. You might put the jar in a larger container when you test.. Just to contain the shattered glass if it fails..
