JUKI DDL-552-2 User Manual

10. Adjusting the position of the synchronizer (Fig.36)
This synchronizer has adopted semi-leading element, non-contacting type called hole IC, so it
is impossible to verify the position of the synchronizer by the tester by pulling out the 12P plug.
Therefore, the position of the synchronizer should be adjusted in the following order:
® Remove the belt.
(D Remove the cover ® of the synchronizer and loosen the screw ®.
(DTurn the power source switch to "ON".
® Match the black indicating lineof the pulley with the redindicating lineof the machine head.
(D If the synchronizer is moved gently by the hand without moving the pulley, the auxiliary
motor will either rotate or stop. So, at the position where the auxiliary motor has started to stop,
tighten the screw ®.
(D Replace the cover of the synchronizer to the original position.
(Note) When the above adjustments are made, do not loosen the screw (© (+ screw), absolutely. If
this part is either loosened or released, sometimes the synchronizer does not function. So,
use extreme caution.
