Paati me te rokiroki, te haumaru
I whakauruhia ki te 200 rita rimu rino, te taumaha kupenga 220 kg / pa.
Kei te rongoa i te maroke, he kirikiri, he waahi. I aukati i te hinganga me te ra, te whakaeke i te ua i te wa e whakahaere ana me te tuku.
I tutaki ki te ahi wera me te maama, ki te whakapiri atu ranei ki te kaihoko oxidizing, na te kino o te ahi. Mena ka tutaki ki te wera nui, te pehanga i roto i te ipu kua whakarahihia, na te kino o te bang.
Mena ka pa atu te kiri, ka tango i nga kakahu kua werohia, ka horoia me te nui o te wai ka tino pai te wai. Mena ka pa te kanohi ki a, ka horoia me te nui o te wai me te kamo ka tuwhera tonu mo te tekau ma rima meneti. Haere awhina awhina.
Pls Whakapā mai ki a maatau ki te tiki i te aora me te MSD. Mauruuru.
