  • Page 7 DOWN The TOP arm (A1) is guided in its cycle by a slot. IT IS VERY IMPORTANT when you open the shed with the right Treadle that this arm goes all the way to the top before depressing the left Treadle to close the shed. (Each Treadle must be depressed individually fully to the bottom).
  • Page 8 Make sure the treadle cables are installed properly and in the groove of each pulley. The Red and Green loop cords start at the left treadle of the loom (stand- ing in the front of the loom) the Black and White loop cords start at the right treadle and are opening the shed.

  • Page 11 While keeping the left treadle down, lift and hold the right treadle at 10" from the floor. Connect the black and white cords while making sure that both arms are completely closed.
  • Page 12 Push down the right treadle. Check that both arms open completely all the way to the nylon stopper. If like in this picture the arm does not touch the nylon stop- per, make the necessary adjust- ment in the loop cords or in the turnbuckles to have this opti- mum open shed.
  • Page 13 PROBLEM WITH THE SOLENOIDS NOT MOVING BACK AND OR THE PATTERN NOT SWITCHING WHEN THE SHED CLOSES. 1) Push down the right treadle in order to com- pletely open both arms 2) Unscrew the magnet bracket 3) Note that the magnet which is probably glued to the bracket has a small red dot.
  • Page 14 With the left treadle depressed, make sure that all the cables are inside the grooves of the top fork. The upper pair of balls is shown in the correct position above.
  • Page 15 Before you run the self test with Proweave, or with Weavelec, make sure that all the solenoid plungers are at rest touching the black pad.
  • Page 16 While the self test is running, check that all cables (one by one) go OUT of the top fork and IN the bottom fork. If they do, the aligment is ok. IF NOT, CALL OR EMAIL TO LECLERC LOOMS FOR MORE INFORMATION.
  • Page 17 If the lower fork balls on no 1 and 2 are too high to be inserted in the fork, it is because the lower fork and comb unit is too low. Loosen the autolock nut and raise the unit until all the balls are all under the fork as the picture in the previous page.
  • Page 18 2 persons are needed to test the unit. One depressing the treadles, the other one checking Cables and Ball position. 1) Depress the left treadle. 2) Check that all balls are above the top fork as in this picture. 3) Make sure that both arms are completely closed (and both of them are touching or almost touching the nylon stoppers).
  • Page 19 Depress the left treadle. Start the Software and the first pattern selection (Plain Weave) All the even or un-even solenoids have to extend fully as in this picture. If one or a few solenoids are not fully extended, that means that the tension on that Cable is too high.
  • Page 20 TOP FORK BOTTOM FORK When all the solenoids are in the fully extended position, check if the balls of a cable are out of the top fork and into the bottom fork. This is very important, is the balls of a cable pushed have the top ball still in the upper fork, you will not be able to make the lift (JAM) Report this situation to us with pictures supporting the explanation.
  • Page 21 1) Depress the right treadle 2) Check that both arms are in the fully opened position and both of them are touching or almost touching the nylon stoppers.
  • Page 22 Open shed, Plain weave Check that every other shaft frame is up and the alternate shafts are down. Check that each ball is in the correct groove of the correct fork. A cable ball can not be IN 2 forks at the same time.
  • Page 23 Your hesitation sequence will soon be habit. There is a short familiarization period for weavers to develop a Treadling tech- nique for the Weavebird Loom. Do not try to weave too fast, too soon. Speed will come as you develop your own Treadling expertise.

  • Page 25 CLOSED SHED WITH LITTLE PRESSURE ON THE LEFT TREADLE: All lower balls out of the fork and lower than the fork CLOSED SHED WITH LITTLE PRESSURE ON THE LEFT TREADLE: The left treadle is near the floor and there is almost even tension on all the loop cord treadle cables.
  • Page 26 OPEN SHED WITH SMALL PRESSURE ON THE TREADLE: The right treadle is near the floor. Both arms A1 & A2 are all the way to the arm guides G1 & G2. There is almost even tension on all the loop cord treadle cables.
  • Page 27 OPEN SHED WITH SMALL PRESSURE ON THE TREADLE: The right treadle is near the floor. The arm A1 is at the top of the groove of the the arm guides G The rolling white nylon piece N1 is on the top of the closed gate G1 so the arm A1 will have to go down in the other groove avoiding a JAM To do that the shed has to open all the way to the top guide TG all the time.
