72cc huni yekucheka cheni ye272XP 61 268

Macheka echainsaw imashini inoshandiswa zvakanyanya mumabasa ekucheka miti munzvimbo dzemasango muChina, uye mainjini avo anozivikanwawo semainjini ekupisa mukati kana kuti mainjini epeturu. Ndiyo chikamu chikuru chechainsaw, chinoshandiswa kugadzira simba nekufambisa nzira yekucheka matanda kuburikidza negetsi rekutumira huni. Injini yechainsaw yakasiyana neinjini dzinoshandiswa pamatarakita. Chainsaw injini ine mastroke maviri, ine simba rakapetwa kaviri pane injini ine mastroke mana.

1. Kana injini yabatidzwa, dzimwe nguva kuputika kunoitika, uko kuri kupisa kusingawanzoitiki.

Kana injini ikaputika, kumhanya kwemoto kunokurumidza, kusvika pamamita 2000-3000 pasekondi, nepo kumhanya kwemoto kwakajairika kuri 20-40 pamamita pasekondi. Nokudaro, tembiricha yeinjini inowedzera zvakanyanya, uye kumanikidzwa kwemasilinda kunowedzerawo zvakanyanya. Hunhu hwekuputika ruzha rwesimbi inogogodza musirinda, kushanda kweinjini kusina kugadzikana, kupisa zvakanyanya, simba rakaderera, uye utsi hutema hunobva mupombi yekubuda mumhepo. Nekuda kwekuputika kweinjini, kushanda kwayo kunoderera, mafuta ekuzora anoderera, uye anotorasikirwa nekushanda kwayo kwekuzora, zvichikonzera kuwedzera kwekuwa kwebearing. Naizvozvo, chiitiko chekudzima moto hachibvumirwi. Chikonzero chikuru chekuputika kweinjini imhaka yehunhu husina kunaka hwemafuta kana musanganiswa usina kunaka wehuwandu hwemafuta uye huwandu hwekumanikidzwa kweinjini. Pamusoro pezvo, zvine chekuitawo nekupisa kweinjini pachayo, nzvimbo yespark plug, chimiro chekamuri yekubatidza, uye saizi yekona yekubatidza yepamusoro. Zvakare, carbon deposits inogona kukonzera kupisa uye kudzikira kwemoto. Kana kuputika kwaitika, vhara vharuvhu yethrottle (throttle) nekukasika, ziva chikonzero chacho, wobva wabvisa.

2. Kupisa kwepamberi

Kubatidza kwekutanga zvinoreva kuti musanganiswa unobvira uri mukati mesirinda unopisa wega usingamiriri kubatidza. Chikonzero chekubatidza kwekutanga ndechekuti panguva yekudzvanya, tembiricha iri mukati mesirinda inenge yasvika patembiricha yekupisa mafuta, saka haifanirwe kubatidzwa uye kutsva yoga. Kana kubatidza kwekutanga kwaitika, injini inopisa zvakanyanya, ichigadzira macarbon akawanda akasiyana-siyana, uye injini inoshanda zvisina kuenzana.

Nekuongorora nekunzwisisa nyaya mbiri dziri mukushanda kweinjini yemoto, tinogona kunzwisisa zviri nani mashandiro echainsaw. Kungoziva uye kugona mashandiro emuchina chete ndiko kunogona kuvandudza kushanda zvakanaka uye kunaka, zvichizadzisa chinangwa chekuchengetedza vashandi nekuderedza mari.
