In addition, follow the safety instructions in the Maintenance chapter for maintenance, servicing and repair work. In addition, follow the safety instructions in the Maintenance chapter for maintenance, servicing and repair work. It is essential to comply with all safety regulations! 认真阅读和理解安全说明在进行维修和维护工作时严格遵守安全操作说明 1.2 Safety valves 安全阀 Pressure limiting valves preventing excessive pressure buildup are installed on the oil sides. The pressure setting is locked by a lead seal and must never be modified.限制过多的压力形成的压力控制阀被安装在阀体的油侧。 压力装置被铅密封锁定，注意这个设定的压力千万不能被改动 。 Never modify the safety valv
