Slowly move the
lead with the nozzle.
Nozzle
P.W.B.
Solder
Lead
Nozzle cleaner (Optional parts)
Wipe away any oxide or old solder
from the nozzle using the hole in
the center of the sponge.
2. Clean the tip of the nozzle.
eep the tinned section of the nozzle
clean and shiny by coating it with a small
amount of solder.
If the tip of the nozzle is coated with oxide,
the nozzle’s heat conductivity will be
lowered. Coating the tip with a small
amount of fresh solder ensures maximum
heat conductivity.
NOTE:
The cleaner is not included.
3. Melt the solder.
• Apply the nozzle to the soldered part and
melt the solder.
NOTE:
Never allow the nozzle to touch the board itself.
• Confirm that the solder is melted.
NOTE:
• To confirm that all the solder is melted, observe the
inside of the hole and the backside of the P.W.B. If
this is difficult to do, try slowly moving the lead with
the nozzle if the lead moves, the solder is melted.
• Never move the lead by force.
If it doesn’t move easily, the solder is not yet fully
melted.
4. Extract the solder.
After confirming that the solder is
completely melted, extract the solder by
pushing the button on the iron.
NOTE:
Never leave any solder remaining inside the hole in
the P.W.B.

MAINTENANCE
Efficient desoldering depends upon the temperature, the quality and quantity of
the solder and flux. Perform the following service procedures as dictated by the
conditions of the iron usage.
During maintenance, please wear gloves and work carefully.
WARNING:
Since the desoldering iron can reach a very high temperature, please work carefully. Except when
cleaning the nozzle and heating element, always turn the power switch off and disconnect the power plug
before performing any maintenance procedure.
Servicing the Desoldering Iron
1. Inspect and clean the nozzle.
• Plug in the power cord, 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 nozzle cleaning pin does not pass
through the nozzle, use the cleaning drill
(option).
NOTE:
• The cleaning drill is not included.
• The cleaning pin will not pass through the nozzle
until the solder inside the nozzle is completely
melted.
• Check the condition of the solder plating,
surface and inside hole of the nozzle.
If it is slightly worn, recoat the tip with
fresh solder.
• If it is worn or eroded, or the inside
diameter seems unusually wide, replace
the nozzle.
NOTE:
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.
• If the cleaning pin and cleaning drill do not
pass through the hole in the nozzle,
replace the nozzle.
The cleaning pin passes
completely through the hole.
Cleaning with the nozzle cleaning pin.
Cleaning with the cleaning drill (option).
• Before cleaning
• After cleaning
Insert the bit while turning it clockwise.
Pull the drill bit out straight without turning it.
solder plating
Diameter of hole is
widened through erosion.
CAUTION
If the cleaning drill is forced
into the nozzle, the drill bit
could break or be damaged.
CAUTION
Please use the proper sized
cleaning pin or cleaning drill
for the nozzle diameter.
NOTE:
Unfortunately, it is often diffi-
cult to observe this condition,
therefore, if desoldering effi-
ciency goes down and all
other parts appear to be O ,
the nozzle is probably eroded
and should be replaced.
