，您nin應ying當dang檢jian查zha機ji蓋gai下xia的de車che架jia焊han接jie點dian
，原yuan來lai的de焊han接jie點dian平ping滑hua細xi小xiao，修xiu複fu過guo的de焊han接jie點dian一yi般ban比bi原yuan來lai的de粗cu糙cao
，兩liang邊bian左zuo右you一yi比bi較jiao，如ru果guo存cun在zai這zhe種zhong現xian象xiang就jiu說shuo明ming該gai車che曾zeng經jing發fa生sheng過guo比bi較jiao嚴yan重zhong的de事shi故gu。甚shen至zhi有you條tiao件jian的de話hua可ke以yi檢jian查zha底di盤pan，看kan看kan底di盤pan部bu件jian的de老lao化hua或huo損sun傷shang程cheng度du。

　　二 注意輪胎

　　汽qi車che起qi重zhong機ji車che胎tai的de磨mo損sun程cheng度du可ke以yi反fan映ying一yi輛liang車che的de使shi用yong頻pin繁fan程cheng度du，尤you其qi是shi前qian輪lun。假jia如ru花hua紋wen扁bian平ping
，邊bian緣yuan已yi全quan無wu棱leng角jiao，說shuo明ming原yuan車che主zhu作zuo業ye頻pin率lv較jiao高gao，而er且qie並bing不bu太tai愛ai惜xi，這zhe樣yang可ke以yi從cong一yi個ge側ce麵mian給gei二er手shou車che打da分fen。

　　四 注意發動機外觀與運轉

　　察cha看kan發fa動dong機ji外wai觀guan
，仔zai細xi檢jian查zha有you無wu漏lou油you漏lou水shui的de痕hen跡ji。點dian燃ran發fa動dong機ji，觀guan察cha排pai出chu氣qi體ti的de顏yan色se。假jia如ru排pai出chu的de氣qi體ti是shi半ban透tou明ming的de淡dan灰hui色se，說shuo明ming發fa動dong機ji工gong作zuo狀zhuang況kuang良liang好hao。如ru果guo是shi藍lan色se說shuo明ming發fa動dong機ji已yi十shi分fen疲pi勞lao。白bai色se顯xian示shi汽qi缸gang墊dian行xing將jiang報bao廢fei。另ling外wai，您nin可ke以yi嗅xiu一yi嗅xiu排pai放fang氣qi體ti的de氣qi味wei，氣qi味wei難nan聞wen的de就jiu說shuo明ming發fa動dong機ji狀zhuang況kuang也ye不bu好hao。

　　五 留心刹車

　　不bu啟qi動dong發fa動dong機ji先xian用yong力li踩cai幾ji下xia刹sha車che
，然ran後hou在zai空kong檔dang狀zhuang態tai下xia繼ji續xu踩cai著zhe刹sha車che踏ta板ban發fa動dong汽qi車che，如ru果guo刹sha車che踏ta板ban有you被bei吸xi引yin下xia去qu的de感gan覺jiao就jiu說shuo明ming這zhe台tai車che的de真zhen空kong助zhu力li係xi統tong正zheng常chang。一yi定ding要yao試shi駕jia一yi下xia，重zhong點dian感gan受shou發fa動dong機ji的de聲sheng音yin及ji加jia速su表biao現xian、底盤是否有異響、 減震效果
、方向與離合是否沉重、 製動可靠性。

　　六 不要“因小失大”
