If you have this Desoldering Gun Station there is something you should be aware of the two screws that hold the motor to mounting for pump can come loose and make raddling noise
One note this unit has been repaired already once because of switching power supply regulator ic chip failure
Now this with the vacuum motor mounting issue yes I give this Desoldering station a very hard work out and use about every weekend to do some type of project
The fix is taking the vacuum pump assembly out and take the metal cover off and you will see the two screws on it
One note if you are also having low vacuum suction from the pump it is serviceable to some extent
This is how you determine if you have a low suction from the pump with a new tip and the temperature set 775*F and using a the smallest diameter tip it should be able to suck the solder from the tip open if not then you might want to service the vacuum pump
Remove the two outer rubber cups and take the middle screw from the connecting rod that is in between the two cylinders and carefully pull the piston out from cylinder there is a flat washer and rubber “O”ring clean up both of them and put some very light grease on the metal washer and on “O” ring and reassemble the vacuum pump assembly and by hand rotate the connector rod several times to make sure it very easy to turn
This should bring your vacuum pump back to useable state again it might not be as good as but very close
I going to do this service to another vacuum pump assembly maybe today and this time I will take some pictures of this and make some more comments about some thing to be aware of while doing this project
This unit has an issue with the cooling fan is squeaking when you frist turn it on for the day I think I have another one from another unit that the controller took a shit and has had the switching power supply failure that was not cost effective to repair it so it getting used for parts
One note about the tips for the gun they have been redesigned so the tip is very thin and then becomes thicker you will definitely not be able to pry component lead with these new tip but I wonder if it will be easier to resurface the tip when it becomes uneven that is the question because the newly deign tips were in the new Desoldering Gun Station that I just bought and have not had time to use it yet but today I will probably use it and let you know what I think about this
I hope this helps anyone who has this Desoldering Gun Station
