Poor Vacuum
Begin the trouble shooting process by removing the Solder Capture Chamber
from the gun. Make sure there is no debris around the large hole in the Breach
Plunger. Briefly turn on the unit and trigger the vacuum. Place your finger tip over
the hole in the center of the Plunger and test the strength of the vacuum. Turn off
the unit. If you have no vacuum at the plunger, go to paragraph “A”. If there is a
vacuum at the Plunger, go to paragraph “B”.
“A” If there is no vacuum at the plunger, pull the black hose off the Black Filter
Housing on the front of the unit. Once again briefly turn on the unit and trigger
the vacuum. This time check the vacuum at the inlet to the Black Filter Housing.
Turn off the unit. If there was no vacuum at the vacuum inlet then there is an
internal problem with the vacuum pump. If you had vacuum at the vacuum inlet
you will have to check the hose that goes up to the Breach of the gun for an
obstruction or kink.
“B” Since we have vacuum at the Breach we will check the path from the tip to
the Solder Capture Chamber. Choose the proper Cleaning Rod for your tip and
insert it into the tip. If the Tip and vacuum pipe are clear you should be able to
push the rod all the way through to the area of the Solder Capture Area.
If the rod will not go through, this is the source of your poor vacuum. Remove the
tip and look down the vacuum tube towards the Solder Capture Chamber. You
should be able to see a clear, unobstructed, path. If not you may have to
reassemble the chamber and heat up the gun and try to clear the pipe with the
cleaning rod. If the tip and the vacuum pipe are both clear then it is likely that you
have a poor seal on the housing of the Solder Capture Chamber. Make certain
that the flat Black Vacuum Seal washer that sits ahead of the Chamber Cap is in its
proper position. Check to make certain that the felt filter is not frayed with pieces
hanging to the sides as this can prevent a good vacuum seal. Inspect the clear
Silicone Seal on the Breach for cuts or tears. Reinstall the Solder Capture Chamber
paying attention to the position of the felt filter and making certain that the
Breach seal seats properly into the Chamber Housing.
Turn on the unit and run it up to temperature and test it on a solder pad.
