If the jump solenoid is not functioning correctly or
needs to be replaced, release the solenoid nut with
wrench included in the accessories kit. The
measurement between the bracket projection to the
solenoid should be 3.5mm.
If the solenoid projects too far, the needle bar will
not move or it will catch. If it does not project far
enough the needle bar reciprocator will not move
correctly.
When assembling the bracket, solenoid and base
plate, adjust the distance of the arm to the bracket
section to 1mm. Fasten with the bracket joint screw.
If the installation position is incorrect and the needle
bar reciprocator touches the needle bar when
jumping, bend the needle bar slightly to adjust.
