Amfani ga tsayayyen nau'in saurin gudu:
Aikin koyon kai, farawa/tsayawa mai hankali
Gano yanayin zafin jiki don hana zafin yanayi daga zama babban zafin jiki don haifar da gazawar zazzabi mai girma.
Gano tge matsa lamba na kayan aikin bayan jiyya don hana matsewar iska mai ƙarfi daban-daban daga zama mai girma ga ɓarna wutar lantarki
Gano zafin injin don kare shi.
