For fensterln definitely not suitable. The time that they will need namely to release the lock, push the safety pin aside! To push the upper ladder section upwards to lock the fuse again and snap the pins ..... and then finally the ladder climb - this time took advantage of their opponent and the shutter is up again to.
Sequentially:
The ladder can be small and compact in a corner. If they needed it can thereby also easy to transport without having to offend somewhere. Stand - she is also folded along relatively safe overturn without equal. Then it starts halt.
You have to solve the big round Sicherungsarretierungen. On both sides (try the times at -10 degrees and without gloves. I recommend this rather not) outwards (effort is already required). If they have then made them think: fine there you go. From push upwards. Since they have but I was wrong.
For now they still have the right and left backup (I'll call it -Hook) hook solve. 4 fuses are to be drawn and to swing outward, then you might up the ladder extend out. Could? Yes could, because but that's not as easy as they might have imagined!
While pushing it to one side, the other side is sinking back down. Pull back the sunken down side up the above disappears again in downward. Crucifix. Well the solution: Pull one side and lock (which can also take little, until they hit the shoot holes as well) and then pull it out the other side and also determine. So far, so high. A few scratches on his hand because not deburred aluminum parts and clamped back of the hand are a matter of honor. Nevertheless done!
But to the initial situation with the window to come back. These above-described construction period they will need, so you should plan well in advance and erichlich ;-) Even if the window is actually closed, they at least clean the gutter, which are also pluses :-)
