FITTING THE WINDSCREEN
The windscreen is fitted in a rubber beading which is at the same time fitted on the edge of the windscreen vane in the cabin.
A rubber strip pressed along the centre line of the beading ensures sufficient pressure to hold the screen and hold both screen and beading to the cabin body, thus preventing its moving and making it airtight.
The removal and refitting of the windscreen requires a certain amount of attention.
To remove the windscreen, carry out the following operations:
147 | Lift and remove the windscreen wiper blade. |
148 | Remove the strip inserted in the windscreen beading. For 1st series. |
149 | Extract by means of a screwdriver the end of the strip from the beading and pull out over its whole length, |
150 | Push windscreen from the inside of the cabin in correspondence to one of the two top corners and with the help of a screwdriver remove the beading from the cabin edge. Continue until thewindscreen is completely removed. |
151 | Fit the larger groove side of the beading to the windscreen glass, starting in the middle of the glass upper edge. |
152 | Continue the fitting of the beading all around the glass (see fig. 58 b). |
153 | Push into the other groove of the beading, starting from the middle of the lower part, a string (see fig. 58c) leaving the end of this hanging on the outside. Insert the string all around the beading leaving the other end loose near the other, |
154 | Place the windscreen into the cabin vane and insert the beading on to the vane edge at the point where the two string ends hang (see fig. 58 c). |
155 | Gradually pull the string away from the inside of the cabin, so that through the elastic deformation of the beading the string will guide the cabin vane edge (see fig. 58c). The groove for the centre strip allows the beading to deform so as to definitely seat itself into the cabin vane. |
156 | Insert the central strip into its groove helping with a screwdriver wet with soap. |
