Short answer: You CAN'T!
Normaly, those x in 1 nozzles are NOT meant to use more than 1 of the nozzles at any time. Normaly, each individual nozzles have a different spray pattern aimed at different useages.
In this case, it's a narrow jet (strong and focalised), a fan shaped jet (general use, whide area) and a rotary/pulsing jet.
If you try to combine the different nozzles, you risk destroying the assembly. It's NOT covered by the guaranty.
Also, you'll loose presure and much of the effeciency.
The intent is to be able to easily and quickly change the nozzle used for different situations.
