ADJUSTING THE TRIMMERS
To check the position of the thread cutting lever
stopper, insert the roller into the blade cam with the
thread cutting solenoid manual handle at the 100
degree position. Make sure the thread cutting lever
is close to the blade cutting stopper. Unfasten the
screw and change the position.
ADJUSTING THE MOVABLE BLADE
To adjust the approach angle of the movable blade,
first check its position. The cutting point should be
about 1mm inside the tip of the fixed blade. If the
movable blade is not adjusted correctly, upper thread
breaks or incorrect cuts can occur. If the position of
the movable blade is incorrect, loosen the upper screw
on the thread cutting drive lever and adjust the blade
manually. When the blade is adjusted correctly, tighen
the upper screw firmly on the thread cutting drive
lever. Check that the upper and lower thread cutting
drive lever can move easily with no movement of the
thread cutting lever shaft bracket.
