MAINTENANCE

Efficient  desoldering  depends  upon  the  temperature,  the  quality  and  quantity  of
the  solder  and  flux.  Perform  the  following  service  procedures  as  dictated  by  the
conditions  of  the  iron  usage.
During maintenance, please wear gloves and work carefully.

WARNING:

Since  the  desoldering  iron  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 Iron

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
(option).

NOTE:

• The cleaning drill is not included.
• The cleaning pin will not pass through the nozzle

until  the  solder  inside  the  nozzle  is  completely
melted.

• 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  eroded,  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  eroded  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 (option).

• Before cleaning

• After cleaning

Insert the bit while turning it clockwise.

Pull the drill bit out straight without turning it.

solder plating

Diameter of hole is
widened through erosion.

     

CAUTION

If  the  cleaning  drill  is  forced 
into  the  nozzle,  the  drill  bit 
could break or be damaged.

     

CAUTION

Please  use  the  proper  sized 
cleaning  pin  or  cleaning  drill 
for the nozzle diameter.

NOTE:

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.
