KeeptheinputvoltagebetweenDC10Vand16V

2、转向机上的标签请不要撕损便于以后本公司对转向机的维护工作；

Thelabelonthesteeringmachineishelpfulinmaintenancework.Donottearitoff.3、接插件必须接触良好：插接器件避免于潮湿、高温、要保证其导电的良好性；

Makesurethattheconnectorsstayingoodcontactandconductivity.Avoidmoistandheat.4、装助力时应尽量把电源负极卸掉，防止装车时因为短路烧坏电路；

Disconnectthenegativepolewheninstallingtheassistantpowertopreventdamagebroughtbyapossibleshortcircuit.5、紧固力矩依据厂家规定：转向轴应转动灵活，无卡滞现象；

Fastenthetorqueaccordingtotheregulationofthemanufacturer.Thesteeringshaftshouldsteersmoothlyandflexibly.6、转向时请勿长时间将方向盘打到极限位置，时间不应超过3秒；

Donotturnthesteeringwheeltoextermepositionforalongtime.Thewheelshouldstayinextermepositionlessthan3seconds.7、发动机工作时尽量不要接插控制器及电机、传感器，防止由于电流对其冲击造成控制损坏；

Donotconnectcontroller,motororsensorwhentheengineisworkingtopreventpossibledamagetocontrolsystemcausedbyimpulseofcurrent.8、线束的安装与连线参照线束接线表；

SeeConnectiontablewheninstallingandconnectingwireharness.9、本机发生用户不能解决的故障非专业人员不要打开机壳，应及时与当地经销商技术服务中心或直接与我公司联系。
