When using the Harris clampless I loosen the clamps off as much as possible, I then thrust the pole upwards, or you can do it straight out in front of you until you get the hang of it, as this is a little easier, you need to have hold of the base of the pole with your right hand (if your right handed), as the pole stops extending you need to get hold of the hose with your botton two fingers, or push it against the base of the pole with your palm, this is to stop it falling back down, most hose will hold up the pole, but the thicker the hose the better, I have some reinforced stuff I got from Brodex I think, and if you hold it quite tight in your fingers it also helps to stop the brush from twisting. When you want to bring the pole down you just release your grip on the hose, you can also stop the pole from crashing down too hard by gripping the hose a bit just before it is completely retracted. Once you get used to it, it is a brilliant way of working, especially on small houses were the the pole is being extended and retracted a lot!!
