Te whakamahinga me te tiaki i te tapahi paraihe hiko e rua-whiu

Te taahiraa tuatahi: Ko mīhini rua-whiu he ranunga hinu me te penehīni te whakamahia, ā, ko te ōwehenga ranunga he 1:50. Neke atu i te 90 te penehīni, ko te hinu motuhake e rua-whiu te mea pai mō te hinu, ko te tohu he 2T, ā, kāore e tino whakaaetia te whakamahi i te hinu e whā-whiu.

Ko te taahiraa tuarua: E taunakihia ana kia whakahaerehia te mīhini hou i roto i te 30, 60 meneti i mua i te whakamahinga, ko te ōwehenga o te hinu me te penehīni he 1:40, ā, ka tohatohahia te hinu kia rite ki te ōwehenga noa o te 1:50 i te wā e mahi ana, ā, kaua rawa e neke atu i te 1:50, ki te kore he angiangi rawa te kukū, ka kukume te mīhini i te rango. Me tohatoha te hinu kia rite ki te ipu tohatoha hinu e piri ana ki te mīhini, ā, kaua te hinu e tohatohahia i te hiahia. He pai ake te whakaranu i te hinu ki te whakamahinga o nāianei, ina rūrūtia te hinu kia ōrite, ka tino āraia te whakamahi i te hinu whakaranu mō te wā roa.

Hipanga 3: I mua i te mahi a te mīhini, tirohia te hinu, ngā mata, ngā nati, ngā pūtu kia mōhio ai kei roto te mīhini i te āhua haumaru o te mahi. Whakahaerehia i te tere iti mō ētahi meneti i mua i te mahi. I te wā e mahi ana, kaua e teitei, e iti rānei te tatau wahie, ā, me whakamahi te tere tere ōrite.

Hipanga 4: Me whakahaere te roa o te taura tarutaru, kaua e neke atu i te 15 cm, ki te roa rawa te taura tarutaru, ka pā ki te mahi noa o te mīhini. Me tāuta tika te mata, me te aro ki te taurite. I mua i te mahi me te wā okioki, tirohia mēnā he wetekina te mata. Ki te wetekina, whakakahangia i te wā tika.

Hipanga 5: I te wā e rongoa ana, me horoi te tinana, me tuku te wahie i konatunatua, ā, me tahu te wahie i roto i te carburetor; Tangohia te mono mura, horoia te waro i runga i te mono mura, ka tāpirihia te hinu rua-whiu l-2ml ki te rango, tōia te tīmatanga kia 2-3 ngā wā, ka tāuta i te mono mura. Me rongoa te mīhini tapahi tarutaru ki te tūranga whakapae, me whakanoho ki te wāhi hauhautanga, maroke, kia matara atu i ngā taputapu hiko me ngā mīhini ahi hei karo i te ahi.

III. Ngā Whakatūpato:
1. I te wā e mahi ana, kaua e mau waewae tahanga, kaua hoki e mau hu, kaua e mau tarau roa, hū tiaki, ā, ko te mea pai ko te mau mōhiti tiaki. I muri i ia tāke hinu, me okioki koe mō te 10 meneti, i te wā okiokinga, tangohia ngā taru me ngā paru i runga i te tihi o te pane o te tarutaru i te wā tika kia taea ai e te mīhini te mahi noa, ā, horoia te paru me ngā putiputi i roto i te pane o te tarutaru kia taea ai e te pane o te tarutaru te mahi noa.
2. Ina te te āhua o te wiri rerekē o te mīhini tapahi tarutaru Ki te tukinga rānei te mīhini tapahi tarutaru ki ngā mea tauhou, me whakamutu tonu. Horoia te totohu wera o te mīhini i muri i ia mahi kia marara ai te wera.

3. Tangohia te mono mura i ia 25 hāora, whakamahia he paraihe waea hei tango i te paru i runga i te hiko, ka whakatika i te āputa hiko ki te 0.6-0.7mm.
4. Ka tangohia te puehu e te tātari hau i ia 25 hāora, ā, me tango pinepine atu i te puehu.
5. Tangohia te pūwero hau i ia 50 hāora whakamahinga, ka horoi i ngā putunga waro i te putanga hau me te putanga o te pūwero hau.
