Specications
Your KAKA 4" THROATLESS SHEAR for
metal cutting is precision designed and
manufactured to allow precise control when
making straight or intricately curved cuts of
any length, in any direction. Hardened, nely
honed blades produce clean, burr-free cuts in
aluminum, steel and other mild metals.
The gear-driven design delivers maximum
shearing power with minimal handle force.

Important
Blades are coasted with a protectant. To
ensure proper fit and operation, remove
coating. Coating is easily removed with mild
solvents, such as mineral spirits, and a soft
cloth. Avoid getting cleaning solution on paint
or any of the rubber or plastic parts. Solvents
may deteriorate these nishes. Use soap and
water on paint, plastic or rubber components.
After cleaning, cover all exposed surfaces with
a light coating of oil.
WARNING
Never use highly volatile solvents.
Non-ammable solvents are recommended
to avoid possible re hazard.

WARNING
1.This tool has EXTREMELY SHARP cutting
blades with amplied leverage on the upper
blade which can quickly cause severe injury
or loss of fingers! Keep fingers and hands
away from moving parts when operating.
2.Always place the handle in the DOWN
position with the Locking Pin inserted
through both the Upper Blade Housing and
the Body in the CLOSED position (Figure 1)
when not in use. The weight of the handle,
left in the up position, can cause the upper
blade to suddenly and unexpectedly drop
with great force resulting in severe injury or
loss of ngers.
3.Handling sharp metal can cause serious
cuts. Wear thick, well-tting work gloves to
prevent cuts from handling sharp metal.
4.Metal particles can be ejected from the
material when cutting. Sheet metal edges
and corners are sharp and can injure eyes.
Always wear ANSI approved eye protection
when operating this tool.
Assembly
1. The KAKA Throatless Shear must be securely
mounted on a heavy, solid workbench, stand,
oor etc., capable of holding the static weight
of the unit plus the stresses from operation.
2.Place the Throatless Shear over the chosen
location then mark mounting hole locations by
tracing holes in the base.
CAUTION
Check for the presence of electrical, air or
other utility lines under the mounting surface
before drilling mounting holes.
3.The use of 1/2” through bolts & nuts or
longer lag screws with substantial washers
and attachment to a structural member is
absolutely necessary.
CAUTION
Always keep the handle in the down position
and the Body in the CLOSED position
(Figure 1) when not cutting. The weight of
the handle can cause the upper blade to
suddenly and unexpectedly drop.
Figure 1
4.Remove the supplied bolt #3 from the
Handle Stub #5 , carefully align the mounting
hole of the Handle #2 over the threaded hole
in the Stub, thread bolt through hole in Handle
and into the Stub then tighten using a 13mm
wrench (not included) (Figure 2).

Operation
1.For Maximum Control and Cutting Force,
begin all cuts by raising the handle #2 fully
and placing the edge of the metal at the point
at which the blades #8 & #12 meet.
2.For Straight Cuts; keep the metal stationary
and flat against shear deck as you draw the
handle #2 downward. As the 1st cut has been
done and the upper blade #12 has reached
the low point, raise the handle then move the
material forward placing the uncut area once
again at the blade intersection point.
3.For Curved Cuts; turn the material left or
right to make curved cuts as needed ( NOTE:
Do not move material forward as you cut ). As
the upper blade #12 reaches the low point,
raise the handle then move the material
forward placing the uncut area once again at
the blade intersection point. Resume left or
right material movement.
WARNING
The weight of the handle can cause the
upper blade to suddenly and unexpectedly
drop.When cuts are done, always place the
handle in the DOWN position.
BLADE ADJUSTMENT
NOTES
- The upper blade is fixed in place while the
lower blade is adjustable.
- The ideal blade gap is equal to 1/4 of the
subject material thickness.
For example: 14-gauge steel will work best
with a blade gap of 0.019” [0.48mm], while 20
gauge should be 0.0094” [0.23mm].
- An alternative method is to gradually
decrease blade gap while cutting paper. The
paper should cut cleanly without pulls, tearing
or folding.
CAUTION
Do not allow blades to come into full contact
with each other or permanent blade damage
can occur.
To measure: use a good quality feeler gauge
and measure at the blade intersection point
with the handle at the halfway down position
(Figure 3).
Figure 3
TO ADJUST
1. Loosen the bolt #10 securing the Lower Blade
Clamp at the left front of the tool (Figure 4).
Figure 4
2. Using a small, straight bladed screwdriver,
Turn the two set screws #15 & #17 (Figure 5)
inward (clockwise) to decrease blade gap, turn
outward (counter-clockwise) while applying a
slight outward pressure to increase blade gap.

manufacturing tolerance variations. Adjust per
Blade Adjustment procedure.
Maintenance
NOTE: Maintenance should be performed
before each use.
1. Lower the Upper Blade assembly, insert
the Locking Pin through both the Upper Blade
Housing and the Body in the CLOSED position
(Figure 1) and Remove Handle.
