27. Tension of timing belt
1. Timing belt is engaged with gears on main and lower shafts.
Too weak tension may result in slippage between shuttle gear and lower shaft
gear due to thread jamming, bunching and fabric snagging.
Too strong tension may result in incorrect operation due to increased machine torque.
＊This checking is needed before adjusting “Needle timing to shuttle”.
2. Loosen two screws on support plate for idler pulley and shift the position of idler pulley
for adjustment.
