7. MAINTENANCE
Properly maintained, the MODEL 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 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.
Cleaning with the nozzle cleaning pin
Cleaning with the cleaning drill
●
Before cleaning
●
After cleaning
The cleaning pin passes completely
through the hole.
Insert the bit while turning it clockwise.
Pull the drill bit out straight without turning it.
Solder plating
Hole is damaged by erosion.
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 accessory).
●
If the cleaning pin does not pass through the
hole in the nozzle, clean with the cleaning drill.
(not included as a standard accessory).
●
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.
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.
• 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.
NOTE:
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.
