5. Maintenance (Desoldering Gun)
Properly maintained, the HAKKO 475 desoldering gun should provide years of good ser-
vice. 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
gunʼs usage.
WARNING : Since the desoldering 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.
Servicing the Desoldering Gun
CAUTION
The desoldering gun will be extremely
hot. During maintenance, please wear
gloves and work carefully.
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.
CAUTION
The cleaning pin will not pass
through the nozzle until the solder in-
side the nozzle is completely melted.
• 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 tip of the nozzle.
• If it is slightly worn, recoat the tip
with fresh solder to prevent oxida-
tion.
• Check the condition of the surface
and inside hole of the nozzle.
• If either is worn or eroded, or the
inside diameter seems unusually
wide, replace the nozzle.
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.
Cleaning with the nozzle cleaning pin
The cleaning pin passes com-
pletely through the hole.
Cleaning with the cleaning drill
• Before cleaning
Insert the bit while turning it clockwise.
• After cleaning
Pull the drill bit out straight without turning it.
Solder plating
CAUTION
If the cleaning drill is forced into
the nozzle, the drill bit could break
or be damaged.
CAUTION
Please use the proper size clean-
ing pin or cleaning drill for the
nozzle diameter.
Diameter of hole is
widened through
erosion.
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.
