This is an image of the assembled traffic light. Figure 1 Figure 2The traffic light and Red/Green man unit are attached to a steel lighting stand and an outer pipe. The stand consists of three sections and the feet. Identify the three sections and remove the top section. N.B., The top section may have dropped down into the lower section. Lay the steel stand horizontally on the floor. Adjust the spread of the feet so that the red tape on the lower section is just above the lower clamp. Tighten the clamp. There are holes in the lower and centre sections to support the Red/Green man.Adjust the centre section so that the holes align. Tighten the centre clamp. Figure 3 Page 2

Place the support bar with the loop of string into the centre section.Insert the top section until it rests on the bar. Figure 4Slide the outer pipe over the lighting stand, ensure the larger diameter end is facing toward the feet of the lighting stand. Rotate the pipe until the holes for the Red/Green man (Fig.3) align. Figure 5 Find the M6 wing bolt assembly. Remove the loose wing nut and washer.Push the assembly through the (Fig.5) holes.Temporarily refit the wing nut and washer on the other side. Figure 6 Page 3

Place the traffic light enclosure at the side of the lighting stand near the top. Figure 7Find the top support bracket and screw the M10 wing bolt into the traffic light. Ensure this is screwed in fully. Figure 8Slide the top support bracket onto the top section of the lighting stand. Figure 9 Page 4

Slide the additional support bracket onto the top support bracket and then on to the top section of the lighting stand. Tighten all the clamps. Figure 10Using two people, raise the assembly to the vertical position. There is a circular guide around the pipe. Adjust the guide so that it fits into the projecting boss near the rear base of the traffic light. Figure 11Remove the temporary wing nut and washer (Fig. 6) and store in a safe place.
