He maha ngā raruraru hei aro atu i te wā e hoko anangā puna hau ka taea te whakahaere:
1. Rauemi: he paipa maitai tui te matotoru o te pakitara, 1.0mm.
2. Te maimoatanga mata: ko ētahi o te pēhanga he mea hanga ki te maitai waro pango, ā, ko ētahi o ngā tokotoko angiangi he mea whakakikorua, he mea tuhi hoki.
3. Kōwhiringa pēhanga: ka nui ake te pēhanga o te tokotoko waipēhi, ka pai ake (he nui rawa hei pēhi, he iti rawa hei tautoko).
4. Kōwhiringa roa: ehara i te mea he raraunga tika te roa o te tokotoko pēhanga hau. Mena ko te tawhiti i waenga i ngā kōhao he 490 me te 480, ka taea te whakamahi noa (ka taea te whakamahi noa mena kei roto i te 3cm te hapa roa).
5. Kōwhiringa hononga: ka taea te whakawhiti i ngā momo hononga e rua (ko te diameter o te kōhao pane momo-A he 10mm, ā, ko te diameter o te pane momo-F he 6mm).
Tikanga tāutanga opuna hau whakahaere:
He painga nui tō te puna hau whakahaere, arā, he ngāwari ki te tāuta. I konei ka kōrerohia ngā mahi noa mō te tāuta i te puna hau whakahaere:
1. Me tāuta te tokotoko piston puna hau ki raro, kaua ki raro, kia whakaitihia ai te waku, kia pai ai te kounga o te whakamākū me te mahi whakaruruhau.
2. Ko te whakatau i te tūranga tāutanga o te pūmau te taurangi mō te mahi tika o te puna hau. Me tāuta te puna hau i te huarahi tika, arā, ina kati, tukua kia neke atu i te rārangi waenga o te hanganga, ki te kore, ka pana aunoa te puna hau i te tatau kia tuwhera.
3. Tepuna haukaua e pāngia e te kaha honga, e te kaha whakawhiti rānei i te wā e whakamahia ana. Kaua e whakamahia hei pupuri ringaringa.
4. Hei whakarite i te pono o te hiri, kaua te mata o te tokotoko piston e pakaru, ā, kāore e whakaaetia te peita me ngā matū ki runga i te tokotoko piston. Kāore hoki e whakaaetia te tāuta i te puna hau ki te tūranga e hiahiatia ana i mua i te rehu me te peita.
5. He hua pēhanga teitei te puna hau, ā, e tino rāhuitia ana te tapatapahi, te tunu, te patu rānei i te mea e pai ana.
Me aro nui i te wā tāutanga: kia mau tonu ai te pono o te hiri, kaua te mata o te tokotoko piston e pakaru, kaua hoki te peita me ngā matū e pania ki te tokotoko piston. Kāore hoki e whakaaetia kia tāutahia te puna hau ki te tūranga e hiahiatia ana i mua i te rehu me te peita. Kia maumahara kaua te tokotoko piston e huri ki te taha maui. Mena me whakarerekē te ahunga o te hononga, ka taea anake te huri ki te taha matau. Ka taea hoki te huri ki tētahi ahunga pumau. Ko te rahi o tepuna hauMe tika te rahi o te kaha, me tika hoki te āputa i te rahi o te whiu o te tokotoko piston, e kore e taea te raka, ki te kore ka tino uaua te pupuri ā muri ake nei.
