Desoldering Tool Does Not Remove Solder - Metcal MX-500 Manuel D'utilisation

1. Check if the tip is heating up by applying solder to the tip. If it does not heat,
follow the steps under "Tip Will Not Heat" earlier in this manual.
2. Turn the power supply off.
3. Open the handle.
4. Replace the Chamber Filter if it appears dirty and full of flux.
5. Replace the Chamber Liner if it is full.
6. Lay the edge of your hand over the top of the collection chamber to provide a
seal. Press the trigger of the tool and verify that you feel a strong suction against
your hand.
7. If the suction is not strong, proceed to step 12. If the suction is strong and you
replaced either the chamber filter or liner, close the tool, insert a cartridge, turn
the system on and press the trigger while melting some solder with the tip.
8. If the solder is not sucked into the tool, try cleaning the tip with a thin wire or
Tip Cleaner.
9. If this does not help, turn the system off, remove the cartridge, and visually
inspect the cartridge seal and chamber seal for leaks (tears, nicks, debris). Close
the tool, remove the cartridge, and place your thumb over the front opening of
the tool while pressing the trigger.
10. If you do not feel a strong suction, try replacing the chamber seal.
11. If you still do not feel a strong suction, adjust the set screw under the front lip of
the top slide latch.
12. If the suction is weak, check the air pressure (80 psi is ideal).
13. If there is still no vacuum generated by the unit, check all air lines to the handle
for cuts, kinks, or obstructions.
14. Clean the Venturi. Squirt flux cleaner in the passage (or on a fresh Venturi), then
pull the trigger for a few seconds (with the handle open).
15. If this does not work, replace the Venturi cartridge as described in "Replacing
the Venturi".
If the above steps do not result in proper performance, call your Metcal representative
or Metcal Technical Service at 800-776-1778 from inside the United States or 1-650-
325-3291 from outside of the United States.
