二手电动叉车

Used electric forklift

日常维护

Daily maintenance

1、清洗二手电动叉车上污垢、泥土和垢埃，部位是：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. Clean dirt, dirt and dirt on used electric forklift truck. The key parts are: forklift and gantry slideway, generator and starter, battery electrode fork column, water tank, air filter.

2、检查各部位的紧固情况，是：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. Check the fastening condition of each part, the emphasis is: fork support, lifting chain tension screws, wheel screws, wheel pins, brakes, steering screws.

3、检查转向器的可靠性、灵活性。

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

4、检查渗漏情况，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, the key points are: the pipe connectors, diesel tank, oil tank, brake pump, lift cylinder, tilt cylinder, water tank, pump, engine oil pan, torque converter, transmission, drive axle, main reducer, hydraulic steering gear, steering cylinder.

5、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, tire pressure check: insufficient should be added to the specified value, confirm no leakage. Check whether there is any damage to the ground and side of the tire, and whether the rim is deformed.

6、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. Brake fluid, water inspection: check whether the brake fluid is within the scale, and check whether the brake pipe is mixed with air. When adding brake fluid, prevent dust and water from mixing. When adding water to the tank, clean tap water is used. If antifreeze is used, the same antifreeze should be added. Do not open the water tank cover when the water temperature is higher than 70 ~C. When opening the cover, pad a thin cloth and do not twist 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 truck: first pull out the oil gauge, wipe off the ruler head, then insert and pull out to check whether the oil level is between two calibration lines. The oil level in the working tank should be between the two calibration lines; too little oil, air will be mixed in the pipeline, too much will spill from the cover plate. Battery electrolyte should also be placed between the upper and lower scales, and the distilled water should be added to the top line.

8、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. Brake pedal, micro-motion pedal, clutch pedal, hand brake check: step down each pedal, check whether there is abnormal dull or stuck. The acting force of the brake handle of the used electric fork driver should be less than 300N, and the hand brake is confirmed to be safe and reliable.

9、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. Examination of belt, horn, lamp, instrument and so on: Check whether the elasticity of used electric forklift belt meets the requirement, if there is no adjustment margin or crack, it should be replaced; Horn, lamp and instrument should be normal and effective.

10、 放去机油滤清器沉淀物。

10. Drain the oil filter deposits.
