Ua ʻike ʻo 87cc 4.2KW i ke kaulahao mana nui no 288 870

ʻO kēlā me kēia mea hana kīhāpai i hoʻohana ʻia no ka manawa lōʻihi e ʻike i nā hewa nui a liʻiliʻi paha. Inā hiki ke hoʻopau koke ʻia nā hewa e pili pono ana i ka hoʻonui ʻana i kona ola lawelawe a mālama i ka hana hana maikaʻi. ʻO ka lawe ʻana i ka chainsaw ma ke ʻano he laʻana, inā ʻaʻole ʻoe maopopo i kekahi mea a nīnau i kahi loea i ka wā e loaʻa ai kahi pilikia, hiki ke pilikia loa. Eia naʻe, inā maopopo iā ʻoe kekahi mau hewa maʻamau e pili ana i nā kaulahao, hiki iā ʻoe ke hoʻoponopono maʻalahi i nā hewa maʻalahi.

Paʻakikī i ka hoʻomaka ʻana i ka mea hoʻoheheʻe chainsaw

I ka hoʻomaka ʻana o ka chainsaw, hana wale ka ʻenekini i kekahi mau leo ​​leo nui me ka ʻole o ka hoʻomau ʻana. ʻOiai ma hope o ka hoʻomaka pinepine ʻana, e mau nō ia. ʻAʻole maopopo kēia he pilikia o ka hoʻopili haʻahaʻa cylinder a i ʻole leakage i loko o ka pahu crankcase, ʻaʻole ia he pilikia o ka pōʻino i nā pahu kukui a me nā uea kiʻekiʻe-voltage o ka ʻōnaehana hoʻāla, a i ʻole ka lawa ʻole o ka ikaika magnetic o ka magneto. ʻO kēia no ka lawa ʻole o ka hoʻopiʻi ʻana, leakage i loko o ka pahu crankcase, leakage o nā pūkuniahi a me nā uea kiʻekiʻe-voltage, demagnetization mau o ke kila magnetic, a me ka lawa ʻole o ka ikaika mana, ʻaʻole hiki ke pahū ke ʻenekini. Inā ka hewa i loko o ka ignition nenoaiu, ina ia mea he engine me ka contact magneto ignition, o ka hapa ka hapanui ma muli o ka wehe 'ana i nā wahi, kuni, aila stains, a me ka hoahu o ka oxide papa; Hiki ke kumu ia ma muli o ka haki ʻana o ke kī hapalua mahina lele a me ka pūnāwai huila huila, a me ka hemo ʻana o ka lima hoʻopaʻa hoʻoneʻe. Inā he magneto non-contact, ʻo ka hapa nui o ia mea ma muli o ka hoʻopili maikaʻi ʻole i ka mea hoʻohui coil.

Inā loaʻa ka hewa i loko o ka ʻōnaehana hoʻolako wahie, ʻo ia ka hapa nui ma muli o ka makū i ka wahie, ka ea i ka paipu wahie, a me ka nui a i ʻole ka nui o ka aila lubricating i loko o ka wahie hui ʻia, hiki ke hoʻopau i ka ʻenekini i ke ahi i ka wā e hoʻomaka ai i ka mīkini anu. . No ka mea ʻoi aku ka nui o ka gravity o ka wai ma mua o ka wahie, waiho ia ma lalo o ka pahu wahie. Ke hoʻomaka ka ʻenekini, hiki ke hoʻolako ʻia ka wahie i loko o ka carburetor no ka puhi ʻana a me ka pahū. Ke komo kēia wai i loko o ka pahu wahie i loko o ka carburetor a i ʻole ka paipu aila, ʻoki ia i ka hoʻolako maʻamau o ka wahie, a hoʻōki koke ka ʻenekini i ka pahū. Eia hou, excessive lubricating aila i loko o ka wahie e pili ana i ka wikiwiki atomization o ka wahie, e paʻakikī i ka hui 'ana i ka ignite, i kekahi manawa igniting, a discontinuous. ʻO ka wahie i loko o ka hui ʻana he waiwai nui, a inā hiki ke hoʻā ʻia e ka ʻulaʻula ikaika ma hope o ke komo ʻana i ka cylinder, e "pololei" koke ia ma muli o ka nui o ka ʻaila ʻaila (ʻo ia hoʻi, ka insulation a puni ka pou waena o ka ʻula. plug a ma waena o nā pou ʻaoʻao ua hoʻopiha ʻia me ka ʻaila ʻaila). Inā nui loa ka wahie hui ʻia a i ʻole ka aila lubricating i loko o ka ʻaila hui ʻia, ʻo ke kinoea hoʻokuʻu ʻia e ka puʻupuʻu i ka wā o ka pahū ʻana he uahi mānoanoa ʻeleʻele.

Paʻa wela kiʻekiʻe o ka chainsaw

ʻO ka hōʻailona maʻamau ʻo ia ma hope o ka hana ʻana no kekahi manawa, kū koke ka ʻenekini a laila ʻaʻole hiki ke huki. He manawa lōʻihi ka hoʻomaka ʻana o ke ahi, a ma hope o ka hana ʻana no kekahi manawa, hiki hou kēia kūlana, a ʻoi aku ka pinepine i ka wā wela. ʻO nā mea i luna nei he kūlana maʻamau kahi e kū ai ke kaulahao i nā wela kiʻekiʻe. He aha kā mākou e hana ai ma kēia kūlana? ʻO ka mea mua, pono mākou e ʻike i nā kumu. ʻO nā kumu maʻamau a me nā hopena penei:

1. Pilikia ea

ʻO ka mea nui ma muli o ka maikaʻi ʻole o ka ea o ka crankcase a me nā ʻāpana plastik, kahi e alakaʻi ai i ka ventila maikaʻi ʻole o nā ʻāpana carburetor a hoʻoulu i ka stalling kiʻekiʻe.

ʻO ka hoʻonā: Ventilation. Inā hoʻohui ʻia kahi uhi alakaʻi ea ma ka huila magnetic a i ʻole ke kahawai ma waena o ka lele lele a me ka carburetor ma ka crankcase hiki ke hoʻonui ʻia, hiki ke hoʻonui ʻia ka nui o ka ea, a i ʻole hiki ke hoʻololi ʻia kahi uhi pahu ventilated maikaʻi a me ka pahu kānana ea.

2. Poor exhaust o muffler alakai i ke kiʻekiʻe wela

Pane: E hoʻomaʻemaʻe i ka puʻupuʻu a i ʻole e hoʻololi iā ia me kahi puʻupuʻu me kahi lua nui. (E hoʻomaopopo: ʻo ka loaʻa ʻana o nā puka hou aʻe ʻaʻole ia he hoʻonohonoho wikiwiki. Ma ka mākeke, ʻoi aku ka maikaʻi o nā lua lua ma mua o ʻekolu mau puka liʻiliʻi.).

3. Haʻahaʻa wela kū'ē o carburetors

Pane: Hoʻohui i nā pad pepa insulation, hoʻoheheʻe, hoʻomaʻemaʻe a hoʻololi paha i nā carburetors.

4. ʻAʻole kūpaʻa ka pūʻolo coil / high-voltage i nā wela kiʻekiʻe

Pane: Hoʻololi pololei.

5. ʻEkolu mau mea o ka cylinder

ʻO ka liʻiliʻi o hoʻokahi o nā ʻāpana ʻekolu, cylinder, piston, a me ke apo piston, he mea ʻilihune.

Pane: E hoʻololi i ka puʻupuʻu lima kaulahao.

6. ʻAʻole kūpaʻa nā sila aila a me nā paipu kaomi maikaʻi ʻole (nā paipu kinoea balance) i nā wela kiʻekiʻe

ʻAʻole kūpaʻa ka sila aila a me ka paipu kaomi ʻino (balance gas pipe) i nā wela kiʻekiʻe, e hopena i ka leakage ea ke kiʻekiʻe ka mahana.

Pane: Hoʻololi i ka sila ʻaila kiʻekiʻe a me ka paipu kaomi ʻino (paipu ea kaulike).
