Whrther the result in all countries and under all circumstances wiil be satisfactory is a questioil we naturaily can’t answer. Since the carrying out had to be done in their spare time and to the staff this meant engagi,ng it into their daily activities, tire results kept the wockr?rs-in-rhe-ficid waiting much longer than had been originally plnnncd.

Mount the assembied blades on pas 21 (fan-shaft), using bolts M4x50 with nuts and washers. -Y- The assembled fan. Sequence of the assembly of various parts. Adjust pm 2 to pas 1 by means of screws. Next adjust pas 6 and pas 14 at the right distance (Notice the slit width has to be 7 mm). Slide pas 4 into the slit and fix the screw to POS 18. You'll have to do this twice, once for the left and once for the right side-wall. Next you'll have to join the side-walls. Situate the fan-shaft between the side-walls. Clamp the funnel-botton in the slit and fix a screw into the side-wall (pas 1) adjusting it to pas 18. Put the winnowing-mill. upright the mounted fan facing up. Slide the joint fan-housing parts (pas 3 and 3A) in the in the drawing dotted slit.
