低成本、率、以工作质量保证产品质量

The routine maintenance of used electric forklift mainly includes these tasks:

1、对电动叉车进行的清洗工作，要清洗这些部位：货叉架及门架滑道、发电机及起动器、蓄电池电极叉柱、水箱、空气滤清器。

1. Carry out comprehensive cleaning for electric forklift, focusing on cleaning these parts: fork frame and gantry slide, generator and starter, battery electrode fork column, water tank and air filter.

2、要对各个部位的牢固情况进行的检查，要留意这几个部位：货叉架支承、起重链拉紧螺丝、车轮螺钉、车轮固定销、制动器、转向器螺钉。

2. Conduct a comprehensive inspection on the firmness of all parts, and pay attention to these parts: fork support, lifting chain tension screw, wheel screw, wheel fixing pin, brake and steering gear screw.

3、检查电动叉车的转向器的可靠性、灵活性。

3. Check the reliability and flexibility of the steering gear of the electric forklift.

4、检查电动叉车渗漏情况，是：各管接头、柴油箱、机油箱、制动泵、升降油缸、倾斜油缸、水箱、水泵、发动机油底壳、变矩器、变速器、驱动桥、主减速器、液压转向器、转向油缸。

4. Check the leakage of electric forklift, focusing on: pipe joints, diesel tank, engine oil tank, brake pump, lifting cylinder, tilt cylinder, water tank, water pump, engine oil pan, torque converter, transmission, drive axle, main reducer, hydraulic steering gear and steering cylinder.

5、电动叉车轮胎气压检查：不足应补充规定值，确认不漏气。检查轮胎接地面和侧面有无破损，轮辋是否变形。

5. Inspection for tire pressure of electric forklift: if it is insufficient, it shall be supplemented to the specified value to confirm that there is no air leakage. Check whether the ground and side of the tire are damaged and whether the rim is deformed.
 

6、电动叉车制动液、水量检查：查看制动液是否在刻度范围内，并检查制动管路内是否混入空气。添加制动液时，防止灰尘、水混入。向水箱加水时，就使用清洁自来水，若使用了防冻液，应加注同样的防冻液。水温高于70℃时，不要打开水箱盖，打开盖子时，垫一块薄布，不要带手套拧水箱盖。

6. Inspection for brake fluid and water volume of electric forklift: check whether the brake fluid is within the scale range and whether air is mixed in the brake pipeline. When adding brake fluid, prevent dust and water from mixing. When adding water to the water tank, use clean tap water. If antifreeze is used, add the same antifreeze. When the water temperature is higher than 70 ℃, do not open the water tank cover. When opening the cover, pad a thin cloth and do not screw the water tank cover with gloves.

7、二手电动叉车发动机机油量、液压油、电解液检查：先拔出机油标尺，擦净尺头后插入再拉出检查油位是否在两刻度线之间。工作油箱内油位应在两根刻度线之间；油太少，管路中会混入空气，太多会从盖板溢出。电瓶电解液也同样要处在上下刻度线之间，不足则要加蒸馏水到顶线。

7. Inspection of engine oil quantity, hydraulic oil and electrolyte of used electric forklift: first pull out the oil dipstick, wipe the head of the dipstick, then insert it and then pull it out to check whether the oil level is between the two graduation marks. The oil level in the working oil tank shall be between two graduation marks; Too little oil will mix with air in the pipeline, and too much oil will overflow from the cover plate. Battery electrolyte should also be between the upper and lower scale lines. If it is insufficient, distilled water should be added to the top line.

8、电动叉车的制动踏板、微动踏板、离合器踏板、手制动检查：踩下各踏板，检查是否有异常迟钝或卡阻。二手电动叉车手制动手柄的作用力应小于300N，确认手制动可靠。

8. Inspection for brake pedal, inching pedal, clutch pedal and hand brake of electric forklift: step down each pedal to check whether it is abnormally slow or blocked. The force of the second-hand electric fork driver's brake handle shall be less than 300N, and it is confirmed that the hand brake is safe and reliable.

9、电动叉车的皮带、喇叭、灯光、仪表等检查：检查二手电动叉车皮带松紧度是否符合规定，没有调整余量或破损有裂纹，须更换；喇叭、灯光、仪表均应正常有效。

9. Inspection of the belt, horn, light, instrument, etc. of the electric forklift: check whether the tightness of the used electric forklift belt meets the requirements, and whether it has no adjustment allowance or is damaged and cracked. It must be replaced; The horn, light and instrument shall be normal and effective.
