• Kutsekeka kapena kutsekeka kwa dzenje, kungayambitse kubowola kokakamira. Choncho, ndi bwino kuyeretsa dzenje nthawi zonse, pochita kuwomba mpweya ndi thanthwe.
• Ntchito yolumikizirana ndi njira yogwirira ntchito pomwe kubowola pansi pa dzenje kumatha kuipitsidwa, kudzera mu kudula ndi zonyansa zamitundumitundu zomwe zimagwera pansi pa dzenje. Pangani lamulo Choncho, nthawi zonse kuphimba lotseguka ulusi mapeto a kubowola chubu pa kujowina. Onetsetsani kuti machubu obowola alibe zodula komanso dothi.
• Kufunika kwa mafuta olondola pakubowola miyala sikungagogomezedwe mopambanitsa. Mu mafuta okwanira imathandizira kuvala ndipo zimatha kuyambitsa kuwonongeka.

4. Kuwombera zovuta

Kulakwitsa (1): Kusakwanira bwino kapena kusakhala ndi mafuta, kumapangitsa kuchuluka kwa mavalidwe kapena kugoletsa

Choyambitsa: Mafuta sakufika pobowola miyala

Chothandizira: Yang'anani mafutawo, onjezani mafuta ngati kuli kofunikira, kapena onjezerani mlingo wamafuta

Kulakwitsa (2): Makina okhudzidwa sagwira ntchito, kapena amagwira ntchito ndi kuchepa.

chifukwa:

①Kupereka mpweya wopukutidwa kapena wotsekedwa

②Chilolezo chachikulu kwambiri, pakati pa pisitoni ndi silinda yakunja, kapena pakati pa pisitoni ndi mkati, kapena pakati pa pisitoni ndi chowulutsira mpweya.

③Kubowola mopanda tsankho

④Piston kulephera kapena kulephera kwa valve ya phazi.

Chithandizo:

①Yang'anani kuthamanga kwa mpweya. Onetsetsani kuti njira zopita ku thanthwe zatseguka.

②Tsukani chobowola mwala ndikuwunika mavalidwe, sinthani gawo lomwe lawonongeka.

③Tsukani chobowola mwala ndikutsuka zonse zamkati

④Tsukani choboolera mwala m'malo mwa pisitoni yosweka kapena khalani tsonga.

Kulakwitsa (3): Kubowola kotayika ndi dalaivala chuck

chifukwa: Impact mechanism yagwira ntchito popanda kuzungulira kumanja.

Chothandizira: Sodzani zida zomwe zagwa ndi chida chopha nsomba. Kumbukirani kugwiritsa ntchito kuzungulira kudzanja lamanja nthawi zonse, pobowola komanso pokweza chingwe chobowola.
