10.7) ADJUSTING JUMP SOLENOID
Solenoid adjustment is required for new or malfunctioning jump solenoids.
10.7.1) Adjusting the standby position (assembling solenoid and bracket)
10.7.2) Adjusting the assembly location (assembling solenoid-attached bracket to the arm)
– Unscrew solenoid nut using the jump solenoid
adjusting spanner and adjust so that the bracket
and the solenoid operation surface are 3.5mm
away. Fasten the nut.
– If the gap is too big, the needle bar controller
can interfere with the solenoid screw and
therefore the needle bar can stop. If the gap is
too small, the needle bar controller can hold the
needle bar even during the jump, causing bad
jumps.
– Adjust so that the processed surface of the arm
is 1mm from the bracket surface. Fix with the
bracket screw.
– If the location is not good, the needle bar
controller can touch the needle bar during the
jumps, making the needle bar work during the
jumps.
