[volt-nuts] Now Pace desoldering maintanance question

[J. Forster]

Yes and no.

You let the pump pump alcohol or mineral spirits through the thing.

You can do it a couple of ways:

Method 1 is to close the front panel vents and with a couple of handpiece
hoses stuck in a jar of solvent just run the sucker. After 30 seconds to a
couple of minutes, discard the used solvent and repeat with clean.
Finally, just let it pump air for a couple of minutes. Do this in a
well-ventilated space.

Method 2 is the same, except you open the unit and disconnect the two
hoses from the barbed fitting on the panel and put those into the jar.

Only use alcohol or mineral spirits, NOT acetone, MEK or anything else.
The irons are off in either case.

Best,

-John
