6. MAINTENANCE
Properly maintained, the FM-2024 desoldering tool should provide years of good service.
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 the gun’s usage.
WARNING :
Since the desoldering tool 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 of nozzle
CAUTION
The desoldering tool may be
extremely hot. During maintenance,
please work carefully.
Inspect and clean the nozzle.
●
Plug in the power cord, turn the
power switch ON and let the
nozzle heat up.
CAUTION
The cleaning pin will not pass through
the nozzle until the solder inside the
nozzle is completely melted.
●
Clean out the hole of the nozzle
with the nozzle cleaning pin
(not included as a standard accessories).
●
If the cleaning pin does not pass
through the hole in the nozzle,
clean with the cleaning drill.
(not included as a standard accessories).
●
Check the condition of the solder
plating on the nozzle tip.
●
Check visually if the nozzle was
eroded.
CAUTION
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 nozzle is still in a good
condition, put some fresh solder on
the nozzle tip to protect solder plated
area from oxidation.
Cleaning with the nozzle cleaning pin
Cleaning with the cleaning drill
• Before cleaning
• After cleaning
Solder plating
Hole is damaged
by erosion.
The cleaning pin passes completely
through the hole.
Insert the bit while turning it clockwise.
Pull the drill bit out straight without turn-
ing it.
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
Unfortunately, it is often difficult to
observe this condition. Therefore, if
desoldering efficiency goes down
and all other parts appear to be
OK, the nozzle is probably eroded
and should be replaced.
• If the cleaning pin and cleaning drill
does 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.
