(1) Ukuba sisikrini esijikelezayo esishukumayo, isizathu esilula nesiqhelekileyo kukuba ukuthambekela kwesikrini akwanelanga. Ngokwenyani, ukuthambekela kwe-20 ° yeyona ilungileyo. Ukuba i-engile yokuthambekela ingaphantsi kwe-16 °, izinto ezikwisihluzo aziyi kuhamba kakuhle okanye ziya kuqengqeleka;

(2) Ukuwa phakathi kwe-chute yamalahle nomphezulu wesikrini kuncinci kakhulu. Okukhona ukuwa kwamalahle kukhulu, kokukhona amandla okuchaphazeleka ngoko nangoko aphezulu kwaye izinga lokusila liphezulu. Ukuba umgama phakathi kwe-chute kunye nesihluzo lincinci kakhulu, inxalenye yamalahle iya kuqokelelana kwisihluzo kuba ayinakudlula kwisihluzo ngokukhawuleza. Nje ukuba isihluzo siqokelelwe, izinga lokusila liya kuba lincinci kwaye umgangatho wokusila we-sihluzo uya kwanda. Ukwanda kobuninzi bokungcangcazela kwesihluzo kuya kunciphisa ngokuqinisekileyo ubukhulu besihluzo, kwaye ukwehla kobukhulu kuya kunciphisa amandla okucubungula isihluzo. Kwiimeko ezinzima, inqwaba yezinto iya kucinezelwa kumphezulu wesikrini wonke, nto leyo ebangela ukuba isikrini singasebenzi. Ngokubanzi, kufuneka kuthotywe i-400-500mm phakathi kwe-chute yokutya kwamalahle nomphezulu wesikrini;

(3) Ububanzi betanki yokutya kufuneka bube phakathi. Ukuba igcwele kakhulu, izinto azinakusasazwa ngokulinganayo kwicala lobubanzi bomphezulu wesikrini, kwaye indawo yokukhusela ayinakusetyenziswa ngokufanelekileyo nangendlela efanelekileyo;

(4) Isikrini sokubhoboza. Xa ilahle limanzi, isihluzo siya kwenza i-briquette kwaye akuyi kubakho sihluzo phantse. Kwimeko enjalo, isikrini sokubhoboza sinokutshintshwa sibe sisikrini sokuwelda.
