Uma ukhetha umshini wokugaya amapayipi we-ERW, izici okufanele uzicabangele zihlanganisa umthamo wokukhiqiza, ububanzi bepayipi lobubanzi, ukusebenzisana kwezinto, ileveli yokuzenzakalela, nosekelo lwangemva kokuthengisa. Okokuqala, umthamo wokukhiqiza uyisici esibalulekile esinquma ukuthi mangaki amapayipi isigayo esingakhiqiza phakathi nesikhathi esinqunyiwe. Ukukhetha isigayo esinamandla okukhiqiza esingahlangabezana nezidingo zakho ngaphandle kokunwetshwa ngokweqile kubalulekile ukuze kuqinisekiswe ukusebenza kahle kokukhiqiza nokulawulwa kwezindleko ngaphakathi kwebanga elamukelekayo.
