以下僅就幾種(zhong)常用(yong)的(de)手動工具及電動工具，介紹其(qi)正確的(de)使用(yong)方(fang)法及安(an)全注意事項：

1.金工手弓鋸(ju)：配(pei)合工作物選用(yong)適(shi)當之鋸(ju)條，例如鋸(ju)切實心(xin)或厚的軟金屬用(yong)每吋14齒；工具鋼、鐵管、硬金屬等用(yong)每籿18齒；而每吋24齒則適(shi)用(yong)于金屬板、金屬管、細鐵條的鋸(ju)切。且向前推鋸(ju)，拉回時再(zai)輕輕提起。

2.扳(ban)(ban)手(shou)(shou)(shou)(shou)(shou)：①應(ying)按(an)工作(zuo)性質選擇(ze)適當尺(chi)寸(cun)的(de)(de)扳(ban)(ban)手(shou)(shou)(shou)(shou)(shou)。②使用(yong)活動(dong)扳(ban)(ban)手(shou)(shou)(shou)(shou)(shou)時(shi)應(ying)向固定邊施力(li)(li)，絕(jue)不(bu)可(ke)朝活動(dong)邊用(yong)力(li)(li)。③扳(ban)(ban)手(shou)(shou)(shou)(shou)(shou)開口(kou)若有磨(mo)損或使用(yong)時(shi)有打滑現象時(shi)，不(bu)可(ke)再繼續使用(yong)，以免打滑傷手(shou)(shou)(shou)(shou)(shou)。④不(bu)可(ke)用(yong)扳(ban)(ban)手(shou)(shou)(shou)(shou)(shou)當作(zuo)鐵陲(chui)敲擊(ji)。⑤不(bu)可(ke)在扳(ban)(ban)手(shou)(shou)(shou)(shou)(shou)柄端再套上管子來增加扳(ban)(ban)手(shou)(shou)(shou)(shou)(shou)的(de)(de)扭力(li)(li)。

3.起(qi)(qi)子：①應(ying)配(pei)合螺絲頭溝槽之(zhi)大小形狀，選(xuan)用(yong)適當之(zhi)起(qi)(qi)子。②起(qi)(qi)子手柄(bing)不可(ke)用(yong)榔頭敲(qiao)擊，手柄(bing)損壞(huai)者應(ying)立(li)即汰換。③不可(ke)將起(qi)(qi)子當作鏨子或(huo)(huo)杠桿使(shi)用(yong)。④檢(jian)(jian)驗電流應(ying)用(yong)電工起(qi)(qi)子，不可(ke)用(yong)一般(ban)起(qi)(qi)子檢(jian)(jian)驗高(gao)壓電。⑤起(qi)(qi)子刃口不可(ke)磨削，以免(mian)破壞(huai)硬化表面。⑥起(qi)(qi)子不可(ke)放在衣(yi)服或(huo)(huo)褲子口袋，以免(mian)碰撞或(huo)(huo)跌倒時受傷。

4.鉗(qian)子(zi)(zi)：①鉗(qian)子(zi)(zi)僅(jin)用(yong)(yong)于(yu)扣緊(jin)、嵌入與移去各(ge)種(zhong)插(cha)銷、釘子(zi)(zi)，以(yi)及切斷或(huo)扭緊(jin)各(ge)種(zhong)電(dian)線(xian)之用(yong)(yong)。②鉗(qian)子(zi)(zi)不能用(yong)(yong)以(yi)旋緊(jin)或(huo)敲打(da)螺(luo)栓或(huo)螺(luo)帽(mao)。③鉗(qian)子(zi)(zi)把(ba)手處(chu)不可(ke)以(yi)敲打(da)或(huo)加(jia)長手柄的(de)方(fang)式來增加(jia)夾(jia)緊(jin)或(huo)切斷的(de)力量(liang)。
