The hot air nozzle is designed such that the vacuum plate lies flat on the component. The vacuum

temperature prior to de-soldering. As an option, it is possible to use a vacuum cup in place of the
vacuum plate.

nozzle, loosen the screw and remove the hot gas nozzle using the Nozzle Change Tool provided.
