Idityaniselwe ukufakwa ngokukhawuleza kwaye kulula, inokusetyenziswa kumacandelo amancinci ekhonkrithi yobume obuqinileyo.
Izitayela zentloko zesicelo ngasinye.
Amaxabiso ovavanyo adweliswe ngezantsi afunyenwe ngokusebenzisa i-200-250kgs / cm ikhonkrithi (akukho kuhlanganiswa).
Umthwalo okhuselekileyo wokusebenza akufanele udlule kwi-25% yexabiso elichaziweyo.

Ukusetyenziswa:Okokuqala, kufuneka sisebenzise i-drill yombane ukubhola ubungakanani obuthile bomngxuma;
Okwesibini, ukubeka iplagi yokwandisa emngxunyeni;
Ekugqibeleni, usebenzisa i-screwdriver ukuqinisa i-screw kwi-tube yokwandisa kude kube yindawo echaziweyo
