马达总成安装注意事项：
1. 安装前请检查液压回油管路是否通畅！并需在齿轮箱检查加注齿轮油，行走齿轮油加注标准为1/2，
2. 行走高低速PS油口切换控制压力2-7Mpa
3. 马达内腔油液卸油压力低于0.2Mpa,以免冲坏骨架油封和打烂液压元件。
4. 液压油清洁度需控制在 NAS 9 级
5. 新机安装后，需在250小时以内检查油位；500小时第一次更换齿轮油，第二次以后齿轮油更换周期在1000小时以内。
正确的安装使用才能让寿命更长久，感谢支持！
注意：总成质保期内因系统油液污染、超负荷使用，缺齿轮油，回油堵塞造成腔内压力过大冲坏液压骨架油封、安装不规范或自行更改、维修，总成元件打烂等情形引起的产品损坏不在质保范围内不予质保！

Proper installation and use are essential to ensure the longevity of the motor assembly. Please follow these guidelines carefully:
1. Before installation, check that the hydraulic return oil circuit is unobstructed. Also, inspect and fill the gearbox with gear oil. The standard filling level for travel gear oil is 1/2.
2. The pressure for switching between high and low-speed PS oil ports on the travel motor is 2-7 MPa.
3. The internal cavity oil discharge pressure of the motor must be kept below 0.2 MPa to prevent damage to the skeleton oil seal and hydraulic components.
4. Hydraulic oil cleanliness must be controlled at NAS Grade 9 or better.
5. After installing a new machine, check the oil level within 250 hours; change the gear oil for the first time at 500 hours, and subsequently every 1000 hours.
Product damage caused by hydraulic oil contamination, overloading, insufficient gear oil, blocked return oil leading to excessive internal pressure damaging the hydraulic skeleton oil seal, non-standard installation, unauthorized modifications, self-repair, or damaged assembly components during the warranty period is NOT covered under warranty!
For specific questions regarding installation, usage, warranty duration, or after-sales service, please contact our authorized agent in China.
