4.1
GENERAL CLEANING
The outer case of iron or station may be cleaned with a damp cloth
using little amounts of liquid detergents.
☞
Never submerge the unit in liquid or allow any to enter
the case of the station.
Never use any solvent to clean the case.
(Decomposition of the writing and / or deformation on
the housing)
4.2
CARE OF TIPS
The tips supplied are iron plated copper and if used properly will
give a long life.
1.
Always keep tips tinned before switching off or storing for a
long period of time; Wipe tip using clean-o-point.
Caution with long hair!
2.
Don't keep iron set at high temperature for long periods
as this will break down the surface of the tip.
3.
Never clean tips with abrasive materials or files.
4.
If any oxide film is formed, this can be cleaned with the clean-
ing brush, isoproyl alcohol or equivalent, and then imme-
diately reheat and retain the tip to prevent oxidation of
wettable surface.
5.
Remove the tip and clean every twenty-four hours or at least
once a week. Remove any loose build up in the barrel.
6.
Do not use fluxes containing chloride or acid.
Use only rosin or activated resin fluxes.
7.
Do not use any compound or antiseize materials on
the wettable surface.

4.3
TIP REPLACEMENT AND DRESSING
Tip can be replaced simply by unscrewing the knurled nut barrel
assembly. The station must be switched off and allowed to cool during
this operation,
as damage may result if the system is left on
without the tip inserted
. After removing tip, blow out any oxide
dust that may have formed in the tip retaining area of the barrel. Be
careful to avoid getting dust in your eyes. Replace the tip and screw
back the retaining knurled nut barrel assembly using only firm hand
pressure to tighten. Pliers should only be used to tighten the nut to
avoid burning your fingers.
Wear protection spectacles!
☞
Care should be taken not to overtighten as this
would damage the heating element.
4.3.1
Commissioning of New Tips
☞
The following procedures should be followed when a new
tip has been installed at any time. It will give the tip much
longer life.
1.
Set temperature to the minimum, then switch power to "ON".
2.
After approx. 1 minute set temperature to 200
°
C (392
°
F).
(Beginning of scale)
3.
Tinn the surface with resin core solder containing
collophonium after having reached 200
°
C (392
°
F).
4.
Set to desired temperature and let it heat for approx. 5
minutes.
5.
Ready for use after reaching the present desired tempera-
ture.
☞
Important:
Remove tip and clean daily if a new tip is
installed and removed any loose build up
in the barrel !
