You pump them while you're wearing them. A lever comes off the tank 
just under your left hand which you use to pump with. (maybe some of 
them can be set up the other way around). The spray wand is at the end 
of a hose that comes around on your other side. You spray with one hand 
and pump with the other. You pump them up before starting (but usually 
after you put the sprayer on your back), and then just pump 
occasionally as you spray to keep the pressure up; you don't have to 
stop spraying to pump. It doesn't take a lot of muscle.

Maximum height depends on the model. Ask the manufacturer. An extension 
wand would probably also help.
