the movable knife (see Figure 2-30).
4. With the thread draped over the movable knife from back to front, gently hold
the thread so there is some slack and then push the knife back until the thread
is cut. This cut should be clean, and should not be frayed.
5. Repeat Step 4 with the thread positioned at different locations across cutting
surface.
6. If the thread is frayed at any location you may need to replace the spring knife,
movable knife, or both.
Replace the fixed blade per the instructions in Section 3 of this manual. Do not
attempt to make any adjustment to the fixed blade. After replacing a fixed blade, it
is advised to operate the TRIM IMMEDIATE command several times to allow the
fixed blade to ’seat’ itself with the movable knife.
