2. Asiasiga ma tausiga
2.1 ： Asiasiga o le pito i fafo:
Asiasi le pito i fafo ole alatoto e siaki pe i ai ni mea ua faʻaleagaina, ona faanumeraina lea; Fai se faamaumauga.
2.2 Asiasi le atigi ma faʻamau:
Siaki pe i ai ni tulaga leak ma faia se asiasiga faamaumauga.
3. Aveese le alatoto
Alatoto tatau ona tapunia i luma o disassemble ma tatala le fesoʻotaʻi faʻamau. E tatau ona filifili le talafeagai le talafeagai fetuʻutuʻunaʻi i looser emo, o Nati o le a faaleagaina faigofie e fetuunaia spanner.
E tatau ona faʻasusuina Rusty bolts ma nati i le karasini poʻo le suavaia o le 'ele' aveʻese; Siaki le faʻasologa itu o filo ona mimilo lemu lea. O vaega ua faʻamatuʻuina e tatau ona faanumeraina, maka ma tausia faʻamaopoopo. Pogai ma faitotoʻa tisiketi tatau ona tuʻu i luga puipui e aloese ai mai le valu.
3.1 Faamamaina
Ia mautinoa e faʻamamaina lemu vaega e ala i le palasi ma le Kerosene, kesi, poʻo le faʻamamaina o soʻoupu.
A maeʻa ona faʻamama, ia mautinoa vaega faʻaopoopo e leai-gaʻo & ele.
3.2 Asiasiga o vaega faaleoleo.
Asiasi uma vaega faaleoleo ma fai se faamaumauga.
Fai se fuafuaga talafeagai tausiga e tusa ma le asiasiga iʻuga.
4. Toe faaleleia o vaega faaleoleo
Faʻaleleia vaega faʻapipiʻi e tusa ai ma le asiasiga iʻuga ma le faʻaleleia o le peleni; suia ia vaega faaleoleo i mea lava e tasi pe a manaʻomia.
4.1 Faʻaleleia o le faitotoʻa:
① Faʻaleleia o le T-slot ： E mafai ona faʻaaogaina le maopoopo i le T-slot toe faʻaleleia, Faʻaletonu T-slot faʻaletonu, ueloina itu uma ma faʻamalosia pa. E mafai ona faʻaaogaina le faʻaogaina o le uelo e faʻaleleia ai lalo ole T-slot. I le faʻaaogaina o togafitiga vevela pe a maeʻa le faʻamaeʻaina ina ia mafai ai ona aveʻese le faʻafitauli ogaoga ma faʻaaoga ai le tuiina PT e asiasia
② Faʻaleleia o pa'ū ：
Paʻu o lona uiga o le va poʻo le ogaoga dislocation i le va o faitotoʻa faʻamaufaʻailoga foliga ma Nofoa faʻamaufaʻailoga foliga. Afai faʻaputuga alatoto faitotoʻa pa'ū, mafai uelo pito i luga ma lalo tina, ona, faʻagasologa olo.
4.2 Faʻaleleia o faʻamaufaʻailoga foliga
Ole mafuaʻaga autu ole faʻasologa i totonu o le faʻamamaina o foliga faʻaleagaina. Afai e ogaoga leaga, manaʻomia e ueloina, masini ma olo foliga faʻamaufaʻailoga. Afai e le ogaoga, na o le olo. O le olo o le autu auala.
a. O le faavae mataupu faavae o olo:
Auai i le pito i luga o olo meafaigaluega faatasi ma workpiece. Tui abrasive i le va i le va o luga, ona minoi lea o le olo meafaigaluega e olo.
e. Olo o faitotoʻa faʻamaufaʻailoga foliga ：
Faigofie auala: tusi lesona faiga taʻotoga
Palu faʻapipiʻi luga o le ipu mafolafola, tuʻu le mea faigaluega i luga o le ipu, ona faʻasolo lea a o olo i le saʻo poʻo le "8" laina.
4.3 Faʻaleleia o faʻavae
a. Afai o soʻo se laʻau luga o faʻamau faʻamau foliga poʻo luga talatala le mafai faʻatusatusa mamanu faʻavae, faʻamau faʻailoga e tatau ona lipea. Faʻaleleia auala: olo mafolafola, lapotopoto olo, olo olo, olo olo ma Cone olo ；
e. Afai e faʻapipiʻi le alatoto> 3%, faʻagasologa Faʻasaʻoina togafitiga e le ogatotonu laʻititi le oloina o masini ina ia mautinoa ai luga maeʻa ma faʻagasologa mea na maua. Faʻasaʻoina metotia: Static pressure faʻasaʻo 、 Malulu faʻasaʻoina ma le vevela faʻasaʻoina.
i. Pogai ulu ulu
Pogaʻi ulu o lona uiga o vaega o le au (sphere o le laʻau, pito i luga o le au, pito i luga pito i luga, faʻafesoʻotaʻi pa ma isi) fesoʻotaʻi ma tatala-ma- latalata vaega. Faʻaleleia auala: tipiina, uelo, faʻaofi mama, faʻaofi faʻapipiʻi etc.
o Afai e le mafai ona faʻamalieina le asiasiga manaʻoga, tatau ona toe gaosia ma tutusa mea.
4.4 Afai o soʻo se mea faʻaleagaina ma le laualuga o flange i itu uma o le tino, e tatau ona faʻagasologa masini e faʻafetaui le tulaga masani manaʻomia.
4.5 Itu uma o le tino RJ fesoʻotaʻiga, pe a le mafai ona faʻatusatusa tulaga manaʻoga manaʻomia pe a maeʻa toe faʻaleleia, e tatau ona uʻamea.
4.6 Suiga o ofu vaega
Ofuina vaega aofia gasket, teuina, O-mama ma isi Saunia ofuina vaega e tusa ma tausiga tausiga ma faia se faʻamaumauga.
5. Faaputuputu ma faapipiiina
5.1 Sauniuniga: Saunia toe faʻaleleia vaega faʻasolosolo, gasket, teuina, meafaigaluega faʻapipiʻiina. Faʻatulaga lelei uma vaega; aua le taoto i le eleele.
5.2 Faʻamamaina siaki: Mea faʻamamā mama (faʻamau, faʻamau, faʻavae, nut, tino, pulou, amo ma isi) ma le Kerosene, penisini poʻo le sui faʻamama. Ia mautinoa e leai-gaʻo & ele.
5.3 Faʻapipiʻiina:
Muamua, siaki le faʻamaeʻaina o au ma faʻamau faʻamau faʻamau foliga foliga faʻafesoʻotaʻi;
Faamama, solo le tino, pulou, faitotoʻa, faʻamaufaʻailoga foliga ia tausisi pea, Faʻapipiʻi totoe vaega i le faʻasologa ma faʻamau faʻamau symmetrically.
