clockwise.
Pull the drill bit out straight
without turning it.
Nozzle Maintenance
1. Inspect and clean the nozzle
●
Turn the power switch ON and let the nozzle
heat up.
●
Clean out the hole of the nozzle with the
nozzle cleaning pin.
●
If the cleaning pin does not pass through the
hole in the nozzle, clean with the cleaning
drill.
●
Check the condition of the solder plating on
the nozzle tip.
●
Check visually if the nozzle was eroded.
CAUTION
The desoldering tool may be extremely hot. During maintenance, please work carefully.
The cleaning pin will not pass through the
nozzle until the solder inside the nozzle is
completely melted.
CAUTION
CAUTION
If the cleaning drill is forced into the nozzle, the drill bit
could break or be damaged.
Please use the proper size cleaning pin or cleaning drill
for the nozzle diameter.
CAUTION
Desoldering efficiency goes down and all other parts appear to be OK, the nozzle is
probably eroded and should be replaced.
The inside hole and the surface of the nozzle is plated with a special alloy. Should
this alloy become eroded by high temperature solder, the nozzle will not be able to
maintain the proper temperature.
Hole is damaged by erosion.
●
If the nozzle is still in a good condition, put some fresh solder on the nozzle tip to
protect solder plated area from oxidation.
• If the cleaning pin and cleaning drill do not pass through the hole
in the nozzle, replace the nozzle.
• If the solder plating on the nozzle tip is worn, replace the nozzle.
• If the inside hole of the nozzle is eroded, replace the nozzle.

3. Clean out the tube in the
heating element with the
provided cleaning pin.
●
Turn the power off after cleaning.
The element cover
assembly is held to
the nozzle changing
tool by pressing this
part from both sides.
(The nozzle is not
held to the nozzle
changing tool. Be
careful when removing them.）
2. Disassemble the heating element.
CAUTION
The heating element is
very hot during operation.
Scrape away all oxidation from the tube in the heating
element until the cleaning pin passes cleanly through
the tube.
CAUTION
・
Be sure the solder in the tube in the heating element is completely heated, before
cleaning the tube.
・
If the cleaning pin does not pass through the tube in the heating element, replace
the heating element.
4. Replace the filters.
• Turn the power switch OFF.
• When the filter pipe is cool to the touch, turn the back holder knob counterclockwize
and pull out the filter pipe.
• Examine the seals (filter holders) at each end of the filter pipe.
Replace : Stiff and/or cracked.
• Examine the spring filter.
Replace : Solder is collected in two-thirds of the spring filter.
• Examine the ceramic paper filter (L).
Replace : Ceramic paper filter (L) is showing signs of stains from flux, is stiff, or
contains any solder.
CAUTION
The filter pipe is very hot.
5. Replacement of station filter
If the filer is showing signs of stains
from flux or is stiff, replace it.
Attach the filter as shown in the right
diagram.
