You see correctly. I've been giving dirty looks to my Hakko 707 and it's probably gonna get some sort of modification.

I find it difficult to remember to do this, and my Pace MBT WILL clog reliably if I forget for a few joints. I have never seen a desolder system with a pump run-on timer, and intend to fit one the next time I have an idle hour.

In effect, my 15 years old JBC desoldering station has this: a timer that power the pump for about one second after you relase the trigger buttom
But it has a lot of other ptoblems, so I bought a ZD-985 (for less thr cost of the spares my JBC requires, and I'm happy with it..

Copper wire is the way to go.
Get some pliers(your favourite pair, probably needle-nose) and grab it and push it gently down trhe hole to mel all the solder and unclog it.
Make sure you tin the tip with the wire inside periodically for good heat transmission.

Then just run the pump a bit to get it all out.

It is better to unclog it before it clogs completely.

Just give it a good ol' wire treatment every once in a while.

I have the drills and prongs but looking after your Hakko FR-301 is more involved than I imagined  :palm:

No!  Use stainless steel wire that solder won't stick to.
