1. Small cleaning sponge
Dampen the small cleaning sponge
with water and then squeeze it dry.
Place it in one of the 4 openings
of the iron holder base.
2. Add water to approximately the
level as shown. The small sponge
will absorb water to keep the larger
sponge above it wet at all times.
*The large sponge may be used alone
(w/o small sponge & water).
3. Dampen the large cleaning sponge
and place it on the iron holder base.
Note: The iron receptacles for the 900
(S) and the 907/908 soldering
irons are different. Be sure to use
the proper one for each type of
soldering iron. (Refer to Parts List).
