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.
The desoldering gun will be extremely hot.
During maintenance, please wear gloves
and work carefully.
CAUTION
The cleaning pin will not pass through
the nozzle until the solder inside the
nozzle is completely melted.
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.
CAUTION
·If the cleaning pin does not
pass through the hole in the
nozzle, clean with the cleaning
drill.
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 oth-
er parts appear to be OK, the
nozzle is probably eroded and
should be replaced.
Servicing the Desoldering Gun
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.
·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
oxidation.
·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.

Maintenance
Properly maintained, the Hakko 470B desoldering gun 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 gunÕs usage.
