Malo a ziro asinthidwa ndipo sakuyenera kusinthidwa.
Mphepete mwachitsulo (mkuyu 1) ndi yoyenera kwa ma valve omwe ali ndi zida zomveka bwino (Fig.2).Yesaninso kupewa kuyika mipope ndi mapampu, nthawi yomweyo mavavu asanafike.
Chithunzi 2
Sinthani sikelo ya gudumu lamanja molingana ndi kapangidwe kake.
Zipangizo zotulutsa mpweya ziyenera kuyikidwa mu makina opangira mapaipi, ndipo makinawo amatha kukhala ndi mpweya, zomwe zingayambitse kutsekeka kwa media, kulephera kwa ntchito yosinthira, kapena phokoso lalikulu;
Ndibwino kuti muwonjezere fyuluta kapena kuyeretsa payipi polowera madzi a valve kuti mupewe tinthu tating'ono ta zonyansa zomwe zimatsekereza chinthu chowongolera valavu;
Samalani chitetezo cha dzenje lodziwikiratu, ngati litakhudzidwa kapena kupunduka, limayambitsa kutayikira kapena kukonza zovuta m'tsogolomu.
Sinthani sikelo ya gudumu lamanja molingana ndi kapangidwe kake.
Vavu iyi ili ndi ntchito yokonzeratu kuchuluka kwa kuthamanga kwambiri.Gwiritsani ntchito wrench ya hexagonal kuti mutembenuzire malire otsegulira malire mozungulira, kuti kutsegula kwakukulu kwa valve kungakhale kochepa, ndipo kukonzanso dongosolo sikudzafuna kusokoneza.
Valve yokwanira ingagwiritsidwe ntchito yokha kuti iwononge kayendetsedwe ka kayendetsedwe kake, kapena ingagwiritsidwe ntchito pamodzi ndi valve yosiyana.Pamene valavu imayikidwa, njira yoyendetsera madzi iyenera kukhala yogwirizana ndi momwe muvi umayendera pa valve.Kuti muwonetsetse kuti muyeso uli wolondola, chonde onetsetsani kuti pali zigawo zowongoka za chitoliro musanayambe kapena pambuyo pa valve (Fig.2)
