Efficient desoldering depends upon the temperature, and the quality and quantity of
the solder and flux. Perform the following service procedures as dictated by the
conditions of use.
During maintenance, please wear gloves and work carefully.
WARNING:
Since the desoldering iron/gun 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.
MAINTENANCE
(Desoldering iron/gun)
Servicing the desoldering tool
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.
Note:
The cleaning pin will not pass through
the nozzle until the solder inside the
nozzle is completely melted.
Verify that the correct cleaning pin is
used for the nozzle. The inside
diameter of the nozzle is stamped on
the side of the nozzle.
• 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 corroded, 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 corroded 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.
• Before cleaning
• After cleaning
Insert the bit while turning it clockwise.
Pull the drill bit out straight without turning it.

Diameter of hole is
widened through erosion.
Note
CAUTION
Please use the proper sized
cleaning pin or cleaning drill
for the nozzle diameter.
If the cleaning drill is forced
into the nozzle, the drill bit
could break or be damaged.
CAUTION
Unfortunately, it is often diffi-
cult to observe this condition,
therefore, if desoldering effi-
ciency goes down and all
other parts appear to be OK,
the nozzle is probably eroded
and should be replaced.
