·Te roa o te hiri: Ka whakamahia e te piston rango he hoahoa mānu, ā, ka tukatukahia te raina rango ki tētahi tukanga motuhake, ka taea ai te whakanui ake i te roa o te ratonga o te hiri piston rango i raro i ngā tikanga kore-hinu;
· He iti te tere o te rahunga: Ka whakamahia e te pūnaha waipēhi he papu tauanga + he takirere whakamuri + he kaitahuri auau, he ngāwari te whakahaere me te iti o te tere rahunga;
· He ngāwari te tiaki: he māmā te hanganga, he torutoru ngā wāhanga, ā, he watea te tiaki. Ka taea te whakakapi i tētahi huinga piston rango i roto i te 30 meneti;
· Te tino pai o te rōrahi: He hanganga whakamatao angiangi te hoahoa o te arai rango, he pai ake te kawe wera, he whakamatao pai i te rango, ā, he pai ake te pai o te rōrahi o te compressor.
· Ngā paerewa tirotiro teitei: Ka whakamatautauria ia hua ki te hēriuma mō te pēhanga, te pāmahana, te nekehanga, te turuturu me ētahi atu mahi i mua i te tukunga
· Te matapae hapa me te whakahaere hauora: Kei te hiri piston rango me te hiri tokotoko piston rango hinu ngā taputapu kimi turuturu, ka taea te aroturuki i te tūnga turuturu o te hiri i te wā tūturu me te whakarite mō te whakakapinga i mua.
