that's just the 1150 how they work is a mystery...
the stand thing is pretty simple, stick the black thing in the back of your wheel hole, there's a twisty ony thingy that twists one...
carefully crank the handle back and it cams over the rounded edgy thingy and bish bash bosh... it's standy upy time...... very good for inspecting things you fancy having a look at.... nice to hang your jacket on not nice to carry from the shed to the courtyard to photograph...
