As has already been observed, after you scale your model down, you need to move the contents closer to the origin. Without doing so, it is so far from the origin that clipping occurs. Just select everything, activate the move tool, click on a convenient point such as the lower left corner, move the mouse a bit to activate the tool, and then type [0,0,0]+enter (or [0;0;0] if your locale uses comma as decimal point). That will move the model to the origin and the clipping goes away.
Try this. No battery left to explain.

If you use the Tape measure tool to rescale the model you won’t have this problem, as the model remains proportionally at the same distance from the origin.
Activate the tool, hit Ctrl, measure one length and then enter in the VCB the value you want to rescale to, hit enter and the whole model will be scaled proportionally to that value.

Thanks for the respond
But i have tried that, didn’t work
Thanks box,
you solved it
Thanks ely,
You have just explained me how to solve it myself.
Problem solved 
I apologize as this will sound snarky, but that means you did it wrong! You missed or messed some detail. I did exactly what I described to your model and it worked just fine.
Which is exactly what I did in the model I posted.
