## Questions & Answers

**Q: How many pieces does this set have**
A: Lego list 1292 pieces for the 42108 mobile crane, mine came with 7 extra parts that were not required. (all the other Lego sets I've done have had extra parts but I've never been short, thankfully).

**Q: Can you dismiss and rebuild it after first time building it?**
A: I can only speak of my own experience.  On page 19 of the manual, step 36, I realised that I had joined the 4 sections incorrectly. I decided to dismantle all, much against my wishes. Either that or I could not continue as further steps would not have fitted.
The point I am making here is that I dismantled my small initial build. I started again, and completed it successfully. 
To answer your question, yes I am sure you could dismantle all and start again. 
Hope I answered your question. Percy Briscoe.

**Q: Does it requires a baterry pack**
A: No.  Assembled correctly all moving parts work by turning relevant handles.

**Q: Are the instructions printed or on a disk ?**
A: They are written - a book of instructions is provided in the box, but they are also available online and can be downloaded.
