M'madera omwe mitengo yamagetsi imakhala yokhazikika, ndalama zogwirira ntchito kwa nthawi yayitali zimakhala zochepa kwambiri kuposa mitundu ya injini ya dizilo, zomwe zimapangitsa kuti ikhale yoyenera kwambiri pamapulojekiti apakati mpaka nthawi yayitali okhala ndi magetsi okhazikika.

Kapangidwe kake ka phokoso lochepa, kuteteza malo ogwirira ntchito. Phokoso la injini yamagetsi ndi lochepa kwambiri kuposa la injini ya dizilo. Kuphatikiza ndi kapangidwe kabwino ka kutchinjiriza mawu, kuipitsa phokoso kumayendetsedwa bwino, zomwe zimathandiza kumanga m'malo ndi nthawi zomwe zimakhala zovuta kumva phokoso, monga m'malo okhala anthu, pafupi ndi zipatala ndi masukulu, komanso usiku.
