Use the drawing for the selected model and check mounting-screw depth, shaft coupling and rear-terminal clearance before assembly. Do not hammer the shaft, force an interference fit or allow side loads to distort the bearings.\u003c\/p\u003e\u003ch2\u003eElectrical Connection and Operation\u003c\/h2\u003e\u003cp\u003eConnect a suitable DC motor driver and the selected 6 V or 12 V supply to the two motor terminals. The rear reference photo identifies a positive terminal and a negative terminal; check the actual markings before connection. Reversing the motor leads reverses rotation. The performance tables identify the reference direction as CW(+); confirm the required viewing direction in the mechanism before use.\u003c\/p\u003e\u003cp\u003eAllow current capacity for startup and provide current limiting or overcurrent protection. Avoid prolonged stall, overload, rapid reversals under load and moisture at the terminals. The 0.2 V or 0.5 V starting-voltage reference is not a substitute for the selected rated supply or a guarantee of starting under load.
