Troubleshooting Jacq3G Loom User’s Manual

front and rear inner bearing carriers are in contact with the hardware at the
bottom of it bearing travel. If the outer bearing carrier touches the hardware
first, apply additional force to overcome the inner to outer carrier force until
the inner bearing carrier is in the correct position. Retighten the button head
cap screws.
Lower knife angle adjustment: Loosen the button head cap screws for the
drive cable clamps mounted to the knife. The lower knife should slide
smoothly without damaging the cable sheathing. Slide the lower knife until
the front and rear inner bearing carriers are ¾” from the hardware at the
top of it bearing travel. If the outer bearing carrier is hitting the hardware
and preventing the inner carrier from reaching the measurement, apply
additional force to overcome the inner to outer carrier force until the inner
bearing carrier is in the correct position (¾” from the hardware at the top of
it bearing travel). Retighten the button head cap screws.
Solenoid bar placement:
Incrementally adjust/test the solenoid mount bar until issue goes away.
Incremental adjustment is typically ½-1 turn of the nut; test with tabby with
alternately activates the upper and lower solenoid bars.
Adjustment can be made independently at front and back hardware,
however it is a good idea to loosen both front and back before making the
adjustment to avoid binding/bowing of the solenoid bar.
Pick the side that is closest to the bad hook. If the bad hook is relatively
centered, adjust both sets of hardware.
Adjust the solenoid mount bar away from the knife if the hook is lifting when
it should not; in when the hook does not lift.
Adjustment Of Slide Bars
Symptom
–
Hooks at rear of Module are not engaging with the slide bar in a consistent
manner. After insuring that the solenoids in question are working properly,
this failure to lift may be indicative of a need to adjust the position of the
slide bars. The cables that control the movement of the bars can stretch,
initially, before stabilizing. The process by which the bars are adjusted is
described here.
