- Press the vacuum pump start button.
The vacuum indicator should run into the red zone
(60% and 80% vacuum). If not, this means air is
getting in somewhere, either through the desoldering
tip, the tank stopper, or the pump inlet filter stopper,
or because the air pump does not function correctly
due to dirty valves which occurs when the air filter
has not been used correctly.

JBC reserves the right to change specifications mentioned
in this instructions manual without prior notice.
The suction indicator should
not go beyond the green
zone. If it runs into the red
zone, this will mean that the
suction circuit is obstructed
in some way and the tip
needs unclogging or the
filters replacing.
To detect air leaks in the
circuit:
- Obstruct the tip inlet orifice
by pressing down on a
silicone disc, or bend the
t u b e c o n n e c t i n g t h e
desoldering iron to the filter.
Checking the suction circuit
To determinate if there is obstruction in the suction
circuit:
- Press the vacuum pump start button, with
the desoldering iron at a temperature of
not less than 250°C to keep the tin solder
melted.
Changing the pump inlet filter
Verify the filter at the entrance of the pump, and
change it if dirty or obstructed, therefor:
Open the filter pulling the flap.
Take out the 2 cotton filters, throw away those
which are soiled and replace them with new
ones. Always use 2 filters.
Close the filter and check the airtightness.
Cleaning the vacuum pump valve
Open the control unit as follow:
- Disconnect and open the control unit.
- Turn it upside down, remove the four rubber
feet and take out the four inner screws.
- Return the station to its normal position and
lift up the lid by getting hold of the sides.
- Undo the four screws fastening the pump cover.
- Clean the valve with a cloth dampened in
alcohol. If it is too soiled, replace it with new
one. Ref. 0982970.
