安装
INSTALLATION

1. 将手轮(1)安装在齿轮操作机构的轴上，并用销钉(2)加以紧固。(如果还没有固定)
   Install handwheel (1) onto gear operator shaft and secure with pin (2). (If not already attached)
2. 逆时针方向旋转手轮(1)，直到全开位置。
   Turn the handwheel (1) counter-clockwise until in full OPEN position.
3. 旋转阀门的阀杆直到阀门处于全开的位置。
   Turn valve stem (5) until valve is in full OPEN position.
4. 确保齿轮操作机构(3)和阀门顶部法兰(6)的安装基座清洁并且干燥。
   Assure both mounting base of gear operator (3) and valve top flange (6) are clean and dry.
5. 将适配器衬套插入齿轮操作机构(3)的镗孔里。(如果必要)
   Insert adapter bushing into gear operator (3) bore. (If necessary)
6. 用阀门的阀杆(5)对准适配器衬套或持论操作机构(3)镗孔。注意：消防防火型号阀门的适配器衬套可能与图示不同。
   Align adapter bushing or gear operator (3) bore with valve stem (5). Note that on Fire Protection models adaptor bushings may differ from illustration.
7. 用至少两个支撑紧固件(7和8)将齿轮操作机构(3)紧固在阀门的顶部法兰(6)上。
   Secure gear operator (3) to valve top flange (6) using a minimum of two supplied fasteners (7 & 8).
8. 用艾伦六角螺栓安装指示器并且加以紧固。(仅限于消防防火阀门齿轮操作机构)
   Install flag and secure with Allen screw. (Fire Protection gear operators only)
9. 将手轮从全开到全闭反复旋转几次，确保操作灵活自如。如果需要对准调节，则参阅停止调节程序。
   Rotate handwheel from full OPEN to full SHUT positions several times to assure proper operation. See Stop Adjustment Procedure if alignment adjustment is necessary.

　　对于消防防火阀门，齿轮操作机构，最重要的是只能采用符合UL，FM和ULC标准要求的，随齿轮操作机构供应的销键(8)。
　　For Fire Protection, gear operators, it is critical to use only key (8) supplied with gear operator to conform to UL, FM, and ULC specifications.
　　注意：齿轮操作机构与阀门阀杆的连接与齿轮操作机构的型号、大小和类型有关。适配器衬套和销键可能与图示不同。
　　NOTE: Connection of gear operator to valve stem varies depending on gear operator model, size, and style. The adapter bushing and key may be different from illustration shown.

维护保养和维修
MAINTENANCE AND REPAIR

　　所有齿轮操作机构都是永久性润滑，不需要维护。万一齿轮操作机构受到破坏或过度磨损，建议更换整个齿轮操作机构。只有手轮(1)，销钉(2)和一些适配器衬套(4)才有维修配件。
　　All gear operators are lubricated for life at assembly and should not require service. In the event of a gear operator suffering damage or excessive wear, it is suggested that the complete gear operator be replaced. Only the handwheel (1), pin (2), and some adapter bushings (4) are available for repair parts.
　　注意：从工厂装运的齿轮操作机构，“预置”安装在处于关闭位置的阀门上。
　　NOTE: The gear operators are shipped from the factory, “pre-set” for mounting to valves that are in the closed position
