With all due respect icewater, your post is just a bit factually incorrect, and for safety reasons of readers who might operate one, I feel I should point out some facts.
The machine I used as an example was a JLG 110HX. On that machine, the "operation envelope" is not designed to allow for full extension, it's designed to prevent full extension, to keep boom extension "within operation envelope". If it extends outside the envelope, the machine will become unstable and can tip. A 110HX at horizontal can not fully extend without tipping.
The 110HX does not have outriggers, as most manlifts don't. Outriggers are an option on some models of manlifts, but not the norm. They are not an option on the 110.
The counterweight on the 110 is fixed on the machine. There is no adding, taking away, or changing of the counterweight on one. As for the tires, they have to be foam filled on the 110 for ballast weight as well as to protect from tire blowout while machine is extended.
On a 110HX, the extension sensor is not tied to the tilt sensor, nor does the tilt sensor disable the elevation during unlevel conditions, wouldn't want someone operating a 110 thinking the tilt sensor would protect them from tipping the machine when it's unlevel when in fact it would not.
Code:
The operation envelope is designed to allow for full extension within the working envelope

the unit if properly set-up and outriggers extended will in fact allow for full boom extension without tipping

Code:
If the unit is tipping without a load and the boom is at horizontal the counterweight should be checked to make cetain it is correct, also the tires can come into play.

The extension sensor is tied into the tilt switch to disable elevation during unlevel conditions.
