2. Use the ruler to check whether the size of the main board and the sub-board is correct. If the shaft is on the side board correctly, pay attention to the shaft first to play a horizontal line, and then use 10 bits to drill the hole 50 cm. 1 must be Straight, then use the 14-female mother to weld on the shaft. Remember to weld perpendicular to the hole in the shaft. Make sure to weld firmly. Align the center of the first piece of the curtain with the hole in the shaft with 10 bits. Punching must be vertical (fastening can also be fast).

3. Put the roller shutter curtain on both sides and seal it with a head to pull it with a rivet (remember to start sealing one block).

4. After the closure, use a rope to turn over the shaft to make a hole in the curtain. Use a rope to hold it. Do not pinch it at one end. Press the handle's ascending key so that the shaft will run to bring the curtain up. The reel will hold the curtain and the shaft. Together (level tightening padding) and lifting the curtain up must be firm.

5, open the mouth of the track adult word.

6. Level the roller shutter curtain and position it on and off the line. The left pulley is the upper limit position and the right is the lower limit position. (Adjust itself according to the needs of the site)

Spring Washer

A ring split at one point and bent into a helical shape. This causes the washer to exert a spring force between the fastener's head and the substrate, which maintains the washer hard against the substrate and the bolt thread hard against the nut or substrate thread, creating more friction and resistance to rotation. Applicable standards are ASME B18.21.1, DIN 127 B.
Spring washers are a left hand helix and allow the thread to be tightened in a right hand direction only, i.e. a clockwise direction. When a left hand turning motion is applied, the raised edge bites into the underside of the bolt or nut and the part that it is bolted to, thus resisting turning. Therefore, spring washers are ineffective on left hand threads and hardened surfaces. Also, they are not to be used in conjunction with a Flat Washer under the spring washer, as this isolates the spring washer from biting into the component that will resist turning.

The use and effectiveness of spring lock washers has been debated, with some publications advising against their use on the grounds that, when tight, the washer is flat against the substrate and gives no more resistance to rotation than a normal washer at the same torque. However, a spring washer will continue to hold the bolt against the substrate and maintain friction when loosened slightly, whereas a plain washer will not.

The benefit of spring lock washers lies in the trapezoidal shape of the washer. When compressed to loads near the proof strength of the bolt, it will twist and flatten. This reduces the spring rate of the bolted joint which allows it to maintain more force under the same vibration levels. This prevents loosening.
