Operation
WARNING
Tremendous external torque loads are placed
on this KAKA Metal Bender during operation.
This tool cannot be operated without adequate
support or severe personal injury or property
damage can occur if it should suddenly be
become dislodged or moves while in use. Before
beginning ANY work with this tool, it is absolutely
necessary that it be securely bolted to a properly
anchored heavy, sturdy, anchored workbench.
CAUTION
The KAKA Metal Bender exerts tremendous
bending and crushing forces in operation which
can present a hand/finger pinch hazard and
cause potentially serious injuries. Avoid moving
parts while operating and wear thick, well-
fitting work gloves to prevent cuts from handling
sharp metal. The use of safety shoes is strongly
recommended.
CAUTION
The KAKA Metal Bender was specifically
designed to be operated by one person only.
Never have one person operate the Handle while
one handles the material workpiece or serious
injury could occur.
NOTICE
Workpiece material should be clean of any rust,
burrs, nicks, welds or coatings before attempting
to bend or interference and binding may occur.
NOTICE
Apply a minimal amount of a light lubricant
to material and die surfaces to ease bending
process. Do not over lubricate.
1. Position the workpiece between the
jaws then rotate the Handle #2 in a
Clockwise direction while holding the
workpiece in place with the opposite
hand. As the moving Jaw begins to exert
pressure on the workpiece, remove your
hand from the workpiece and continue to
rotate Handle #2 bending the workpiece
as you go.
NOTE: The 8mm Shear Pin in the joint of the
Drive Bar and Upper link is designed to fail
under excess pressure. If replacing, use a softer
material 8mm pin or mild steel bolt (FIG 3).
2. As the desired bend is achieved, stop
Clockwise rotation and reverse rotational
direction of the Handle to release the
completed workpiece.
FOR PRODUCING REPEATABLE BENDS
1. To record the depth and angle of bend:
Using the gauge located along the slot on
top of the tool body, record the dimension
aligned at the rear edge of the Drive Bar
(FIG 3).
