rotate the knife guard back until the knife blade is fully exposed. While
holding the knife guard open slowly release the front roller arm and allow
it to extend outward. This will allow the knife guard locking mechanism to
hold the knife guard open for easy blade replacement. The knife blades
have open slots to allow for easy slide on / off replacements. The knife
blade is notch for proper orientation of the blade. Refer to figure 12A and
12B.
 Oil Pad:
Regularly lubricate oil pad with SAE #30 non-detergent oil. Never use
penetrating type oil; this will dissolve the adhesive which secures the pad
to the knife guard. Refer to figure 12A.
Warning: –
Use extreme care when working near the knife blade. The
blade is extremely sharp. If care is not taken severe personal injury can
occur.
