1.日常保养;检查、清洗或更换空气滤芯;清洗冷却系统内部;检查和拧紧履带板螺栓;检查和调节履带反张紧度;检查挖掘机进气加热器;更换斗齿;调节挖掘机铲斗间隙;检查前窗清洗液液面;检查、调节挖掘机空调;清洗驾驶室内地板;更换破碎器滤芯(选配件)。清洗冷却系统内部时,待发动机充分冷却后,缓慢拧松注水口盖,释放水箱内部压力,然后才能放水;不要在发动机工作时进行清洗工作,高速旋转的风扇会造成危险;当清洁或更换冷却液时,应将机器停放在水平地面上;要按照表3更换冷却液和防腐蚀器。
1. Daily maintenance; check, clean or replace the air filter element; clean the inside of the cooling system; check and tighten the track shoe bolts; check and adjust the track reverse tension; check the excavator air inlet heater; replace the bucket teeth; adjust the excavator bucket clearance; check the front window cleaning liquid level; check and adjust the excavator air conditioning; clean the cab floor; replace the crusher filter element (optional). When cleaning the interior of the cooling system, slowly loosen the water filling cap after the engine is fully cooled to release the internal pressure of the water tank. Do not clean the engine when it is working, because the high-speed rotating fan will cause danger. When cleaning or replacing the coolant, the machine should be parked on the horizontal ground; the coolant and corrosion inhibitor should be replaced according to table 3.
2.挖掘机新机工作250h后就应更换燃油滤芯和附加燃油滤芯;检查挖掘机发动机气门的间隙。
2. Replace the fuel filter element and additional fuel filter element after the new excavator works for 250h; check the valve clearance of the excavator engine.
3.启动发动机前的检查项目。检查挖掘机冷却液的液面位置高度(加水);检查挖掘机发动机机油油位,加机油;检查挖掘机燃油油位(加燃油);检查v液压油油位(加液压油);检查空气滤芯是否堵塞;检查电线;检查喇叭是否正常;检查铲斗的润滑;检查油水分离器中的水和沉淀物。
3. Check items before starting the engine. Check the coolant level of excavator (add water); check the engine oil level and add oil; check the excavator fuel level (add fuel); check the V hydraulic oil level (add hydraulic oil); check whether the air filter element is blocked; check whether the horn is normal; check the lubrication of the bucket; check the water and sediment in the oil-water separator.
4.每100保养项目。挖掘机动臂缸缸头销轴;动臂脚销;动臂缸缸杆端;斗杆缸缸头销轴;动臂、斗杆连接销;斗杆缸缸杆端;铲斗缸缸头销轴;半杆连杆连接销;斗杆、铲斗缸缸杆端;铲斗缸缸头销轴;斗杆连杆连接销;检查回转机构箱内的油位(加机油);从燃油箱中排出水和沉淀物。

5.每250h保养项目。检查挖掘机终传动箱内的油位(加齿轮油);检查蓄电池电解液;更换发动机油底壳中的油,更换发动机滤芯;润滑回转支承(2处);检查风扇皮带的张紧度,并检查空调压缩机皮带的张紧度,并作调整。
5. Maintenance items every 250h. Check the oil level in the final drive box of the excavator (add gear oil); check the electrolyte of the battery; replace the oil in the engine oil pan and replace the engine filter element; lubricate the slewing ring (2 places); check the tension of the fan belt and the air conditioning compressor belt, and make adjustments.
6.每500h保养项目。更换挖掘机燃油滤芯;检查回转小齿轮润滑脂的高度(加润滑脂);检查和清洗挖掘机散热器散热片、油冷却器散热片和冷疑器散热片;更换液压油滤芯;更换终传动箱内的油(仅在500h时进行,以后1000h一次);清洗挖掘机空调器系统内部和外部的空气滤芯;更换液压油通气口滤芯。
6. Maintenance items every 500h. Replace the excavator fuel filter element; check the height of lubricating grease of rotary pinion (add grease); check and clean the radiator fins, oil cooler fins and cooler fins of excavator; replace the hydraulic oil filter element; replace the oil in the final drive box (only at 500h for the first time, once after 1000h); clean the air filter elements inside and outside the air conditioner system of the excavator; Replace the hydraulic oil vent filter element.
7.每1000h保养项目。更换挖掘机回转机构箱内的油;检查减振器壳体的油位(回机油);检查涡轮增压器的所有紧固件;检查涡轮增压器转子的游隙;发电机皮带张紧度的检查及更换;更换防腐蚀滤芯;更换终传动箱内的油。
7. Maintenance items every 1000h. Change the oil in the rotary mechanism box of the excavator; check the oil level (oil return) of the shock absorber housing; check all fasteners of the turbocharger; check the clearance of the turbocharger rotor; check and replace the belt tension of the generator; replace the anti-corrosion filter element; replace the oil in the final drive box.
8.每2000h保养项目。清洗液压油箱滤网;清洗、检查涡轮增压器;检查发电机、启动电机;检查发动机气门间隙(并调整);检查减振器。
8. Maintenance items every 2000h. Clean the filter screen of hydraulic oil tank; clean and check the turbocharger; check the generator and starting motor; check the engine valve clearance (and adjust); check the shock absorber.
