Awesome Technic Vehicle

What a set! It's got great functions like a 2 speed gearbox, winch, steering, tilting bucket and suspension. Lots of stickers but they really add to the look. Plus it has a terrific side build, a chainsaw. I love these non-licensed sets as they're reasonably priced. I wish it had an alternate build but other than that there's not much to be critical about. It's one of the best value Technic sets you can buy.

Where are Building Instructions?

Hi LEGO, this set is awesome, i liked it to build, but the problem is with PDF instructions that seems to be not yet published in your data base, for this set, 42140 and 42141. I am experienced with online instructions and i have bought 42140 and 42141 also but i can't find them on your site. Can you publish them please?
