a) disconnect the vacuum tube from the fitting on the front panel. Place your finger over the hole and depress the
vacuum switch. You should now have a strong vacuum. If not: return the station to the point of sale to have the
pump repaired.
b) disconnect the in-line filters from the iron assembly. Depress the vacuum switch, replace the filling of the in-line
filters if there is little suction or if the filters are discoloured.
c) Remove the solder collector from the desoldering iron assembly, place your finger over the hole and depress the
vacuum switch. Clean or replace the collector tube in case of insufficient suction.
d) Depress the vacuum switch and clean the tip with the included spring wire if there is no suction. Read "10.
Cleaning Procedure for Clogged Tips".
10. Maintenance
Desoldering tips can be replaced simply by unscrewing the barrel nut assembly. Turn off the station and allow it to
cool first. Damage to the soldering station may occur if the system is left on and the removed tip has not been
replaced.
After removing the tip, you should blow out any oxide dust that may have formed in the tip receptacle. Be careful not
to get dust in your eyes. Replace the tip and tighten the screw. Pliers can be used to avoid contact with hot surfaces
BUT SHOULD BE USED WITH CAUTION because overtightening may cause damage to the element or fuse the tip
to the element.
11. Cleaning Procedure for Clogged Tips
CAUTION: BE VERY CAREFUL NOT TO BURN YOUR FINGERS WHEN CLEANING THE TIP.
1. Move the spring wire (included) back and forth in order to clean the tip.
2. Raise the temperature of the heating element to allow the clogged solder to melt. Clean the tip by sliding the
spring wire up and down until the passage is clear (see fig. 1)
3. Unscrew the barrel nut assembly (fig. 2 & 3).
4. Use a pair of pliers to remove the tip (fig. 4 & 5).
5. Reinsert the stainless tube in the heating element to melt the solder, as shown in fig. 6. This will take
approximately 5 seconds.
6. Remove the stainless tube and shake loose the molten solder. The tip should now be unclogged (fig. 7). Put the
tip back in place and screw down the barrel nut assembly. Do not screw it down too tightly!
