Adjustment Of The Shuttle Race Thread Guide - JUKI PLK-J6040 Technical Manual

6-2-5. Adjustment of the shuttle race thread guide

According to following procedures, assemble the removed shuttle race thread guide.
(1) Match the hole in the shuttle race thread guide (No.1) with the needle bar center line (No.3) so that the
shoulder (No.4) of the shuttle race thread guide matches with the rear side line of the needle (No.6). At
this time, make sure that there is a clearance between the hook retainer (No.7) and the hole of shuttle
race thread guide (No.2) at least the thread can be passed through. (The standard clearance is 0.8mm.)
The wide clearance causes the trimming failure. After adjustment tighten the screws (No.5).
