Maintenance
Wear gloves and use caution when handling and removing the
swing blades which have sharp edges.
Replacing the Swing Blades
1. Using two 22mm wrenches, remove the top lock nut (right-
hand, regular thread) and the jam nut followed by the swing
blade.
2. Reinstall the sharpened or a new swing blade in the orientation
shown (see Figure 18).
3. Install the jam nut until it just touches the blade carrier using
two 22mm wrenches to allow for the blade swing action, then
install the locknut on top.
4. Repeat steps 1 through 3 for the other swing blade side.
