Hakko FR-206 reconditioning and restoration - project log

[hatmoose]

Care package arrived from the USA today - parts to recondition the pump and valve of the "desolder" section of the machine. For some reason they decided to send the stand for the desolder tool in a different package that is due on Monday...


The pump consumables are the diaphragm and the valve plate and the large number of filters.
Thus far I have not been able to test the pump motor. It won't run without the desolder tool. The motor itself is so expensive I didn't want to risk building a test harness for it. So hopefully I can just recondition the consumables - a new pump motor is $US150... lets hope it's OK


The valves have no consumables. Maintenance is cleaning out with alcohol - looks like one of the valves is for the desolder tool and the other is for the hot air wand. Again these are over $US100 each, I won't be using the hot air on this station so as long as one of them is still good I can swap them around

Sometimes you wind yourself up for a massive job - then it turns out to be really fast, that was the case today.

Despite being 10 years old, and sold as "defective untested junk" the pump, valves and etc are all ing good working order. I replaced the front filter, fitted the new desolder tool and it worked perfectly first time. Industrial quality tools really are a treat.

I'll probably fully recondition the pump + valves anyway because I have the parts and I just can't resist a damn good fiddling.

Good news tho - one of the ports on the front seems to be defective - it gives a sensor error, but if I put the station into maintenance mode it can get it to heat the tips up until they are read hot - probably reduced the service life of the tip by a thousand hours so I'll do some more work on that.

If anyone has a schematic or a service manual for the Hakko FR-206 do please PM me

Every now and again the Google monetisation algorithm breaks and accidentally gives the content that I actually want.

Mainly posting here so I don't forget - these test modes will be gold when I have to rebuild the pump and etc

Brilliant video here, there are THREE service modes

1 Hold the dial and switch on (you can use this to adjust a lot of settings)
2 Hold buttons 1 and 3 and switch on (you can use this to reset the password, and to set up the foot switch, and to test many of the pump, air, relay functions)
3 hold buttons 1, 2, and 3 and switch on (you can use this to check the sensors, and to set the foot switch)
