起動前的準備工作
1.檢查發動機機油(you)。不足的添加(jia)機油(you),使(shi)油(you)面處于機油(you)標(biao)尺(chi)上(shang)、下(xia)刻(ke)度之間。
2.檢(jian)查傳動箱齒輪(lun)油。如果(guo)油位太(tai)低,添(tian)加齒輪(lun)油到注油孔的(de)下邊緣。
3.檢查(cha)發動機的燃油。不夠(gou)的加說明書指(zhi)定的燃油。
4.檢查離合器拉線。張緊(jin)(jin)度不對的,松開鎖(suo)緊(jin)(jin)螺母,把拉線調整到合適位置。
5.檢查(cha)油門(men)拉線(xian)。拉線(xian)位(wei)置不合(he)適的,通過鎖緊螺母(mu)把拉線(xian)調整(zheng)到合(he)適位(wei)置。
6.檢查(cha)傳動(dong)皮(pi)帶(dai)張(zhang)(zhang)緊(jin)度。張(zhang)(zhang)緊(jin)度不合適的通過(guo)對張(zhang)(zhang)緊(jin)輪的調整可以把傳動(dong)皮(pi)帶(dai)調整到合適的張(zhang)(zhang)緊(jin)度。

起動
多數的小型(xing)耕(geng)作機械采用(yong)手(shou)拉反沖起(qi)動(dong)(dong)(dong)(dong),也有采用(yong)搖把起(qi)動(dong)(dong)(dong)(dong)的,如“IZS-20型(xing)雙輪耕(geng)整機”。起(qi)動(dong)(dong)(dong)(dong)前先(xian)松開(kai)離合器,把變速(su)桿置于空檔位置;打開(kai)點(dian)火開(kai)關;把油(you)門開(kai)到(dao)1/2—1/3位置;根據(ju)不(bu)同狀(zhuang)況,把阻風門關到(dao)不(bu)同的程度(一般冷(leng)車起(qi)動(dong)(dong)(dong)(dong)時(shi),阻風門關閉或留3毫米(mi)左右(you)間隙,熱車時(shi)阻風門關 1/2左右(you))。起(qi)動(dong)(dong)(dong)(dong)時(shi)先(xian)緩慢拉動(dong)(dong)(dong)(dong)起(qi)動(dong)(dong)(dong)(dong)繩幾次,然后(hou)用(yong)力迅速(su)拉起(qi)動(dong)(dong)(dong)(dong)繩。起(qi)動(dong)(dong)(dong)(dong)后(hou)應先(xian)低(di)速(su)運轉2—5分鐘,在此期間,檢查機器有無不(bu)正常響聲(sheng)、漏油(you)、螺栓松動(dong)(dong)(dong)(dong)等(deng)不(bu)正常現象,如果發現異常應立即檢查排除(chu)
