the first thing to do is make sure the screws holding this casting have not become loosened.
No. 6.— To Remove Film Guide Rollers, 19339, P. 1, follow Instruction No. 5 and then pull out the split key at the end of the spindle, which will release the parts. You cannot get the guide roller spindle out until you have released part 19320, P. 1, as per Instruction No. 5.
No. 7.— Film Tracks, 19317 and 19318, P. 1, are of spring steel, and are removable. When in the course of time they become worn it is only necessary to order new parts (they are right and left hand, as per numbers given on P. 1, therefore order the one you want by number}. Remove screws (six of them) 19344, P. 1, lift off parts 19320 and 19319, P. 1, take out the old tracks and put in the new. They are notched to fit the screws, hence you cannot get them wrong, even if you try. Be careful and don't drop the small screws. A magnetized screwdriver is an excellent tool with which to handle small parts. See General Instruction No. 19.
No. 8.— To Remove Part 19325, P. 1, follow Instruction No. 5.
No. 9.— To Remove Upper Film Guide, 19321, P. 2, take out two screws, 20636, P. 2.
No. 10.— Gate Latch, 18758, P. 3, may be removed by taking out screws 18207 and 20406, P. 3. Screws 18207 and 18207 (one at the top and one at the bottom) serve to regulate the distance of the gate from the machine casting. They should be so set that the distance between the machine casting and the gate casting is the same at both sides of the gate. Unless the gate sets thus the tension shoes will exert unequal pressure on the film. Should it ever be necessary to move these screws be sure their lock nut is set up tightly when' you have finished. If at any time the gate latch should fail to work right it is possible the small coil spring behind it has become too weak and needs stretching. This can easily be accomplished by removing the gate latch.
No. 11.— The Automatic Fire Shutter Governor may be removed by loosening screw 18779, P. 3, which is the small set screw in collar 18778, P. 3, on the outer end of its spindle, and set screw 8132, P. 3. Having done this you may slip spindle 19331, P. 3, carrying gear on its inner end out, which releases the fire shutter. The hub, which set screw 8132 holds to the shaft, and which contains screws (two of them) 18795, P. 3, is a part of the clutch disc which holds the governor weights. The governor cover, 18791, P. 3, may be
