　　【農(nóng)機網(wǎng) 編輯視角】 夏季氣溫高且雨水充沛，一方面農(nóng)機長時間作業(yè)不停歇易發(fā)生故障，另一方面易遭雨淋和水淹，如果不及時對機車進(jìn)行清洗和保養(yǎng)，會嚴(yán)重危害拖拉機等農(nóng)機的機械性能與使用壽命。下面說幾點農(nóng)機日常使用和保養(yǎng)注意事項：

　　1、要按季節(jié)正確選用潤滑油。夏季和冬季的潤滑油不能混用。夏季潤滑油易受熱變稀，抗氧化性差，易變質(zhì)，甚至造成燒瓦抱軸等故障。因此，應(yīng)將曲軸箱和齒輪箱里換上夏用潤滑油，經(jīng)常查潤滑油數(shù)量、油質(zhì)情況，并及時加以更換。
 
　　2、水箱開鍋后，不要立即用手打開水箱蓋。以防發(fā)生燙傷事故，更不能立即加入冷卻水，極易造成缸蓋或缸體“炸裂”。也不要立即將發(fā)動機熄火，應(yīng)怠速運轉(zhuǎn)一段時間，等發(fā)動機冷卻水自然降溫后再添加冷卻水。
 
　　3、長期不使用的農(nóng)業(yè)機械，應(yīng)盡量放置車庫。如果放在露天地，應(yīng)在履帶或輪胎下邊墊上厚木板，以防橡膠件腐蝕、老化。切斷電源，關(guān)閉電源總開關(guān)。卸掉電瓶負(fù)極搭鐵線或?qū)㈦娖啃断聛硗L(fēng)保管。
 
　　4、及時清洗農(nóng)用機械機上的泥土、雜草。卸下排氣管，清洗里面的污水泥沙。及時清洗發(fā)動機外表油污。發(fā)動機外部如果油污過厚會影響散熱，給各種零部件故障埋下隱患，用高壓噴射的方法，將不腐蝕機體部件的清洗劑把發(fā)動機部件清洗一新。
 
　　5、涼身防爆胎。夏天氣溫高，輪胎橡膠易老化，嚴(yán)重時會出現(xiàn)爆胎現(xiàn)象。因此拖拉機在行車中要隨時檢查輪胎氣壓，發(fā)現(xiàn)輪胎過熱、氣壓過高，應(yīng)將車停在陰涼處降溫，不可用冷水潑沖，否則會導(dǎo)致途中爆胎。
 
　　6、為防止發(fā)動機產(chǎn)生過熱現(xiàn)象，保養(yǎng)時，應(yīng)注意風(fēng)扇皮帶不能沾機油，以防打滑，皮帶要盡量保持松緊適度。長途行駛途中要注意適時休息，盡量選擇陰涼處，并打開發(fā)動機罩通風(fēng)散熱。當(dāng)輪胎氣壓因受熱而增加時，應(yīng)立即停車降溫，不然就有爆胎的危險，特別注意不得用放氣及潑冷水的方法來降低輪胎氣壓和溫度。
 
　　另外，保養(yǎng)農(nóng)機還要做到“三勤”，即手勤、眼勤、耳勤。一般農(nóng)機具在發(fā)生故障之前都會有異?，F(xiàn)象，如能做到“三勤”，農(nóng)機具的各種故障是會及時發(fā)現(xiàn)和排除的，從而減少不必要的損失。
