To reduce risk of injury or damage to the unit
• Before each use, inspect the unit to ensure it is clean.

BEFORE FIRST USE
WARNING
Sharp Blade Hazard.
To avoid injury, handle with caution.
1. Keeping sharp edges away from you, carefully wash
Blade Assembly in warm, soapy water and rinse
thoroughly to remove the thin layer of protective oil.
2. Place the unit on a clean, flat surface.
3. Check blade alignment by slowly lowering Pusher
Head Assembly onto Blade Assembly; they should slide
smoothly together. If there is resistance, ensure Blade
Assembly and Pusher Head Assembly are correctly
matched and carefully remove obstructions as necessary.
NOTICE: Do not operate if unit or blades are
misaligned or damaged.
TENSIONING BLADES
NOTICE: Blade tension must be checked before first and
every use. Failure to inspect and tension Blade Assembly may
lead to poor performance and blade damage not covered
under warranty.
Tools You Will Need
• Cut-resistant gloves
• 3/8" (10 mm) socket and socket wrench (¹⁄₄" drive
recommended)
• Torque wrench (optional)
NOTICE: HAND TIGHTEN ONLY; power tools could
permanently damage the unit.
NOTICE: It is important to perform the following steps
in order. Changing the sequence could
damage the unit.
1. Inspect position of the Blade Assembly at the front and
left sides of the Base Assembly frame. Blades should be
evenly spaced against the inside of the frame. See image
of compression spacing in the next column.
2. If the Blade Assembly is not evenly spaced against the
frame, use a socket wrench to tighten the screws on the
front and left sides as much as possible; corresponding
O-rings between the Blade Assembly and the frame
should be compressed to approximately ³⁄₃₂" thick.
2. If you have a torque wrench, use it to verify the screws
are tightened to 70 in lbs.
NOTICE: HAND TIGHTEN ONLY; power tools could
permanently damage the unit.
OPERATION
NOTICE: Failure to inspect and tension blades before each
use could lead to poor performance and blade damage that
will void the warranty.
1. Verify unit is clean; check blades and replace and/or
tension as needed. Do not use if blades are damaged,
misaligned, or not properly tensioned.
2. Check blade alignment by slowly lowering Pusher Head
on the Blade Assembly; head and blades should slide
together smoothly. If they do not, examine pusher fingers
for nicks, burrs, or rough edges and smooth with a small,
flat file as needed; be sure to wash/rinse away debris.
Also check for uniform space between pusher fingers
and straighten the fingers as needed.
3. Prepare food, up to a quarter head of lettuce at once.
4. Lift handle and center food—flat side down—on blades.
5. If using the Lettuce King™
I, move hand from Blade
assembly to a leg of the unit. If using the Lettuce King™ IV,
hold the Handle, remove hand from Blade Assembly and
push the Lock Arm in to release the Pusher Head
Assembly.
6. While holding the Handle, use a strong, quick, downward
motion to thrust the Pusher Head into the food so the
blades cut through entirely.
7. Repeat steps 1–3 until you have enough wedges.
8. Clean and lubricate the unit after each use. Refer to the
following CLEANING section for instructions.
CLEANING

1. Raise the handle to the highest position—see Features
and Controls section.
2. Use the included brush to clean away larger pieces.

unsharpened side; push out food pieces with a nylon
brush as needed.
