Momwe mungakulitsire zida za tungsten carbide:

1. Anthu aimirire kumbali ya chopukusira kuti zidutswa zisawuluke ndi kuvulaza anthu pamene gudumu lopera likusweka;
2. Tsegulani mtunda wapakati pa manja awiri akugwira mpeni, ndipo gwirani m’chiuno ndi zigongono zonse kuti muchepetse kunjenjemera ponola mpeni;

3. Pamene mukunolazida za tungsten carbide, chida chotembenuzira chiyenera kuikidwa pakatikati pa gudumu lopera, ndi nsonga ya chida yopendekera pang'ono m'mwamba pafupi ndi 3 ° mpaka 8 °.Pambuyo pokhudzana ndi gudumu lopera, chida chotembenuza chiyenera kuyenda mozungulira kumanzere ndi kumanja.Pamene atungsten carbidechida chotembenuza chimasiya gudumu lopera, chida chosinthira chiyenera kukwezedwa m'mwamba kuti chiwopsezo chakuthwa chisawonongeke ndi gudumu lopera;

4. Pogaya pamwamba pamphepete, mchira wa chogwiritsira ntchito umapatutsidwa kumanzere ndi ngodya ya ngodya yayikulu yotsika;pogaya mbali yachiwiri, mchira wa chogwiritsira ntchito umapatutsidwa kumanja ndi ngodya yaing'ono yochepetsera;
5. Pamene mukunola chida chokhotakhota, nthawi zambiri gwirani kutsogolo kwa chida chokhotakhota ndi dzanja lanu lamanzere ngati fulcrum, ndipo tembenuzani mchira wa chida chotembenuza ndi dzanja lanu lamanja.
