## Questions & Answers

**Q: Power will it work got power from volvo 6x6 kit wondered if it could be controllable**
A: I don't think so.

**Q: Does this set have pneumatic parts?**
A: No, this set has no pneumatic parts or functions. Movement occurs by turning what is referred to as the hand of God black wheel.
This black gear/wheel when manually turned causes the bucket to move, also lifts/lowers the arm holding the bucket.
I hope I have satisfactorily answered your question.
