1、接通電(dian)源：根據需要撥動電(dian)源選擇(ze)(ze)開關(guan)，即電(dian)源指(zhi)(zhi)示(shi)燈亮.電(dian)源選擇(ze)(ze)開關(guan)指(zhi)(zhi)向(xiang)真(zhen)(zhen)空為(wei)真(zhen)(zhen)空封(feng)(feng)口(kou)，指(zhi)(zhi)向(xiang)真(zhen)(zhen)空充(chong)氣為(wei)真(zhen)(zhen)空充(chong)氣封(feng)(feng)口(kou)。

2、將裝有物(wu)品的(de)塑料袋(dai)(dai)(dai)置放(fang)真空室內.袋(dai)(dai)(dai)口整(zheng)齊地擺在熱封條上（如作充氣包裝至少應有一只噴咀插(cha)入袋(dai)(dai)(dai)口內）。

3、壓下機蓋(gai)，面板上抽(chou)(chou)氣（真空）指示燈亮.真空泵開(kai)始抽(chou)(chou)氣，機蓋(gai)即被自動吸住，抽(chou)(chou)真空旋鈕可根(gen)據包(bao)裝要(yao)求調(diao)節真空度高(gao)低，調(diao)節時，視刻度由低至高(gao)，幅度要(yao)小。

4、當抽(chou)(chou)氣(qi)達到設定的時間（即所要求的真(zhen)空度）時，即抽(chou)(chou)氣(qi)結束，抽(chou)(chou)氣(qi)指(zhi)示(shi)(shi)燈(deng)熄(xi)滅，充(chong)(chong)(chong)(chong)(chong)氣(qi)指(zhi)示(shi)(shi)燈(deng)亮(liang)，以示(shi)(shi)充(chong)(chong)(chong)(chong)(chong)氣(qi)開始(shi).充(chong)(chong)(chong)(chong)(chong)氣(qi)旋鈕可(ke)調節(jie)充(chong)(chong)(chong)(chong)(chong)氣(qi)時間長(chang)短（即充(chong)(chong)(chong)(chong)(chong)氣(qi)量(liang)多少(shao)），方法同上.如(ru)不(bu)需(xu)要充(chong)(chong)(chong)(chong)(chong)氣(qi).將電源開關撥到真(zhen)空位(wei)置，程序(xu)自(zi)動進人真(zhen)空包裝，充(chong)(chong)(chong)(chong)(chong)氣(qi)指(zhi)示(shi)(shi)燈(deng)熄(xi)滅。

5、抽氣(qi)(qi)或充氣(qi)(qi)完(wan)畢(bi)時，指示燈隨之(zhi)熄滅，熱(re)封(feng)(feng)(feng)指示燈亮，即進入封(feng)(feng)(feng)口程序，面(mian)板上設有熱(re)封(feng)(feng)(feng)時間(jian)及溫度(du)調節旋(xuan)(xuan)鈕(niu)，以適應不(bu)同厚薄材料，調節時間(jian)及溫度(du)時，旋(xuan)(xuan)動幅度(du)要小，防止熱(re)封(feng)(feng)(feng)溫度(du)突然增高，燒壞熱(re)封(feng)(feng)(feng)配(pei)件。

6、當達到設定(ding)熱(re)封時(shi)間時(shi)，熱(re)封指(zhi)示燈熄滅，以視熱(re)封結束(shu)(shu)，即真空室經電磁閥進(jin)入大氣，直至機蓋自動(dong)抬啟(qi)，真空充氣包裝(zhuang)過(guo)程全部結束(shu)(shu)，準備進(jin)行下次包裝(zhuang)循環。
