由于管道(dao)疏(shu)通(tong)(tong)機(ji)(ji)使(shi)用220V危險的(de)電(dian)，工作的(de)場(chang)所(suo)又濕又滑，要特(te)別謹慎小心。常有管道(dao)疏(shu)通(tong)(tong)機(ji)(ji)漏電(dian)傷(shang)人事件發生。 管道(dao)疏(shu)通(tong)(tong)機(ji)(ji)旋轉的(de)彈簧軟軸在管道(dao)內遇(yu)阻力(li)時(shi)，會打(da)結纏手，工作時(shi)應戴(dai)加厚(hou)的(de)塑料手套，小心作業(ye)。

管(guan)道疏(shu)(shu)(shu)(shu)(shu)通(tong)(tong)(tong)是(shi)人們日常(chang)生活長用到的(de)(de)(de)一(yi)(yi)(yi)種維修服務，一(yi)(yi)(yi)般指(zhi)家(jia)庭下(xia)水管(guan)道疏(shu)(shu)(shu)(shu)(shu)通(tong)(tong)(tong)，工業管(guan)道疏(shu)(shu)(shu)(shu)(shu)通(tong)(tong)(tong)清洗。家(jia)庭下(xia)水管(guan)道疏(shu)(shu)(shu)(shu)(shu)通(tong)(tong)(tong)的(de)(de)(de)工具(ju)有手(shou)搖式疏(shu)(shu)(shu)(shu)(shu)通(tong)(tong)(tong)器，電動疏(shu)(shu)(shu)(shu)(shu)通(tong)(tong)(tong)機。原理(li)是(shi)通(tong)(tong)(tong)過旋轉(zhuan)把(ba)能有彎度彈性的(de)(de)(de)鋼(gang)絲轉(zhuan)進堵(du)塞(sai)(sai)的(de)(de)(de)下(xia)水管(guan)道里，把(ba)堵(du)塞(sai)(sai)物布條，頭(tou)發之類的(de)(de)(de)東西帶出來。還有一(yi)(yi)(yi)種工具(ju)叫一(yi)(yi)(yi)炮(pao)通(tong)(tong)(tong)，是(shi)一(yi)(yi)(yi)種氣(qi)壓疏(shu)(shu)(shu)(shu)(shu)通(tong)(tong)(tong)工具(ju)，用高壓的(de)(de)(de)原理(li)沖(chong)開堵(du)塞(sai)(sai)的(de)(de)(de)下(xia)水管(guan)道。生活中常(chang)用的(de)(de)(de)皮(pi)踹子就是(shi)這樣(yang)的(de)(de)(de)原理(li)踹開堵(du)塞(sai)(sai)的(de)(de)(de)管(guan)道的(de)(de)(de)。工業管(guan)道疏(shu)(shu)(shu)(shu)(shu)通(tong)(tong)(tong)的(de)(de)(de)管(guan)道因管(guan)道大(da)小用的(de)(de)(de)疏(shu)(shu)(shu)(shu)(shu)通(tong)(tong)(tong)機差別比較(jiao)大(da)，100MM一(yi)(yi)(yi)下(xia)的(de)(de)(de)管(guan)道跟家(jia)庭下(xia)水道疏(shu)(shu)(shu)(shu)(shu)通(tong)(tong)(tong)一(yi)(yi)(yi)樣(yang)疏(shu)(shu)(shu)(shu)(shu)通(tong)(tong)(tong)。對大(da)的(de)(de)(de)管(guan)道用管(guan)道疏(shu)(shu)(shu)(shu)(shu)通(tong)(tong)(tong)車，高壓清洗車來做。
