3.5 Hood and Knife Latch Adjustments
The hood and knife latch work together as the primary safety feature of this machine. They should be
checked for proper operation every time the machine is serviced.
1. Lower the clamp to the table. Remove the clamp handle, cutting lever handle, and top cover.
2. Raise the hood. The hood should remain in the UP position when released. If it does not,
tighten the screws that mount the hood to the machine base (Figure 18).

3. When the knife is in its furthest up position, the knife latch should be engaged with the knife
keeper. The knife should not be able to be lowered unless the knife latch is moved to the
right. If it can be lowered without moving the latch, the latch, keeper, and torsion spring must
be replaced. The replacement procedure follows in section 3.5.1 Knife Latch Replacement
on page 20.

4. Check for secure hardware on the latch and keeper. Reinstall the clamp handle, cutting lever
handle, and top cover.
