7-9) JUMP SOLENOID ADJUSTMENT
Adjust the position of the jump solenoid if the solenoid has been replaced or it malfunctions.
1) Adjusting the Standby Position (assembling the
solenoid and the bracket)
① Use the spanner for jump solenoid adjustment
(included in the SWF basic kit) to unfasten the
solenoid. Re-fasten the nut with the solenoid 3.5mm
away from the bracket.
② If the space is larger than 3.5mm, the solenoid will
interfere the needle. If the space is smaller than 3.5mm,
the needle bar controller will hold the needle in the
JUMP CODE.
2) Adjusting the Installation Position (assembling a solenoid-installed bracket on the base plate)
① Adjust so that the bracket is around 1.5mm from the base plate ([Fig.7-20]). Fasten the bracket screw.
② Incorrect position of the bracket will interfere with the needle movement, as the needle bar controller will hold
the needle in the JUMP CODE.
