Conjunction of separable verbs?

Question

One can use a conjunction like *und* to link two (or more) verbs, as in *Ich lese und schreibe*, but what happens when one or more of the verbs is separable? For the sake of concreteness, here's an example: how would one use *aufbauen* and *abbauen* in a sentence meaning something like *I build and dismantle the apparatus every day*?

Answer 1

In this case, since the word stem " bauen" is the same you can say : Ich baue jeden Tag Geräte auf und ab.

But,if the wordstem is different, like in the following case "aufbauen" and "abbrechen" the word order would be like this: Ich baue Möbel auf und breche sie ab (=I assemble furniture and break them down). Imagine "und" as a connection between two sentences where you use a separable verb.

But watch out: other conjunctions might demand a different word order.

Answer 2

You would have to say that you are building the apparatus and then you are dismantling it, which is:

Ich baue den Apparat auf und dann baue ich ihn ab.
