SAFETY PRECAUTIONS
Metal working can be dangerous if safe
and proper operating procedures are not
followed. As with all machinery, there are
certain hazards involved with the
operation of the product. Using the
machine with respect and caution will
considerably lessen the possibility of
personal injury. However, if normal safety
precautions are overlooked or ignored,
personal injury to the operator may result.
Safety equipment such as guards,
hold-downs, safety glasses, dust masks
and hearing protection can reduce your
potential for injury. But even the best
guard won’t make up for poor judgment,
carelessness or inattention. Always use
common sense and exercise caution in
the workshop. If a procedure feels
dangerous, don’t try it.
REMEMBER: Your personal safety is
your responsibility.

occasionally have to be removed. DO
NOT USE acetone or brake cleaner as
they may damage painted surfaces.
Follow manufacturer’s label instructions
when using any type of cleaning product.
After cleaning, wipe unpainted metal
surfaces with a light coating of quality oil
or grease for protection.
WARNING
DO NOT USE gasoline or other petroleum
products to clean the machine. They have
low flash points and can explode or cause
fire.
CAUTION
When using cleaning solvents work in a
well-ventilated area. Many cleaning
solvents are toxic if inhaled.
TRANSPORTING AND LIFTING

large clearance area around the
machine is important for safe and
efficient working conditions.
Follow these guidelines when lifting:
●Always lift and carry the machine with
the lifting holes provided at the top of the
machine.
●Use lift equipment such as straps,
chains, capable of lifting 1.5 to 2 times the
weight of the machine.
●Take proper precautions for handling
and lifting.
●Check if the load is properly balanced
by lifting it an inch or two.
●Lift the machine, avoiding sudden
accelerations or quick changes of
direction.
●Locate the machine where it is to be
installed, and lower slowly until it touches
the floor.
●The lift truck must be able to lift at least
1.5 –2 times the machines gross weight.
●Make sure the machine is balanced.
While transporting, avoid rough or jerky
motion, and maintain a safe clearance
zone around the transport area.
●Use a fork lift with sufficient lifting
capacity and forks that are long enough
to reach the complete width of the
machine.
●Remove the securing bolts that attach
the machine to the pallet.
●Approaching the machine from the side,
lift the machine on the frame taking care
that there are no cables or pipes in the
area of the forks.
●Move the machine to the required
position and lower gently to the floor.
●Level the machine so that all the
supporting feet are taking the weight of
the machine and no rocking is taking
place.
INSTALLATION
IMPORTANT:
Consider the following when looking for a
suitable location to place the machine:
●Overall weight of the machine.
●Weight of material being processed.
●Sizes of material to be processed
through the machine.

Operation Manual W-2416Z
Model W-2416Z
- 6 -
●Space needed for auxiliary stands,
work tables, or other machinery.
●Clearance from walls and other
obstacles.
●Maintain an adequate working area
around the machine for safety.
●Have the work area well illuminated
with proper lighting.
●Keep the floor free of oil and make sure
it is not slippery.
●Remove scrap and waste materials
regularly, and make sure the work area is
free from obstructing objects.
●If long lengths of material are to be fed
into the machine, make sure that they will
not extend into any aisles.
Before beginning assembly, take note of
the following precautions and suggestions.
●LEVELING: The machine should be
sited on a level, concrete floor. Provisions
for securing it should be in position prior
to placing the machine. The accuracy of
any machine depends on the precise
placement of it to the mounting surface.
●FLOOR: This tool distributes a large
amount of weight over a small area. Make
certain that the floor is capable of
supporting the weight of the machine,
work stock, and the operator. The floor
should also be a level surface. If the unit
wobbles or rocks once in place, be sure
to eliminate by using shims.
●WORKING CLEARANCES: Take into
consideration the size of the material to
be processed. Make sure that you allow
enough space for you to operate the
machine freely.
Anchoring the Machine
●Position the machine on a firm and
level concrete floor.
●Maintain a safe operating distance
around the machine.
●Anchor the machine to the floor, as
shown in the diagram, using bolts and
expansion plugs or sunken tie rods that
connect through holes in the base of the
stand.
Adjusting the Setback
Setback is the distance from the front
edge of the finger to the front edge of the
clamp block as shown in (fig. 6). This

Operation Manual W-2416Z
KAKA Industrial®
- 7 -
distance is determined by the gauge
(thickness) of the piece part and inside
radius of the bend. The setback is
typically 1-1/2 - 2 times the material
thickness.
1.To adjust, make sure all the fingers are
properly aligned to each other and the
hold down assembly is not locked in the
down position.
2.Loosen the setscrews at the back of the
hold down assembly as indicated by the
“*”in (fig. 7). Insert a tool, such as an
allen wrench, into one of the spooked
holes of the eccentric hub and rotate it,
which moves the hold down assembly
either forward or back. When the fingers
are at the correct setback distance and
parallel to the clamp block edge, tighten
the setscrews “*”.
Adjusting the Clamping Pressure
The clamping pressure may have to be
adjusted as the thickness of the piece
part changes. A suitable pressure should
have a medium resistance when pulling
back on the hold down handle. At the end
of the stroke there should be a definite
locking of the piece part under the hold
down assembly.
1. Loosen the turnbuckle jam nuts on
both sides of the hold down assembly.
Rotate the two turnbuckles until the
desired tension is reached.
2. Retighten all four jam nuts.

OPERATION
When performing basic bending
operations it is important that the fingers
of the brake are parallel with the edge of
the clamping block. Also make sure you
have the proper setback and clamping
pressure set for the thickness material
being bent.
CAUTION
Always wear proper eye protection with
side shields, safety footwear, and leather
gloves to protect from burrs and sharp
edges.
Keep hands and fingers clear of the
clamping beam. Stand off to the side of
the machine to avoid getting hit with the
bending apron as it comes up to bend.
When handling large heavy sheets make
sure they are properly supported.
Bending Sheet Metal
1. Lift and rotate the clamping handle (cw)
clockwise to raise the clamping assembly.
2. Insert the piece part between the
clamp block and the brake fingers.
3. Align the fingers of the hold down
assembly to the scribed bend line of the
piece part and clamp in place by pulling
the clamp handle back.
Note: DO NOT force the clamping handle.
The holding pressure only needs to be
tight enough to hold the sheet metal from
moving when bending.
4. Pull up on the bending leaf handles
until the piece part has reached the
desired bend angle.
5. Lower the bending leaf, raise the hold
down assembly, and remove the bent
piece part.
6. If you are doing box and pan bending,
choose fingers that closely match the
dimensions of the finished piece.
BENDING ALLOWANCE
In order to bend sheet metal accurately,
you will need to consider the total length
of each bend. This is referred to as bend
allowance. Subtract the bend allowance
from the sum of the outside dimensions of
the piece part to obtain the actual overall
length or width of the piece. Because of
differences in sheet metal hardness, and
whether the bend is made with the grain
or against it, exact allowances must
sometimes be made by trial and error.
However bend allowances for general

Operation Manual W-2416Z
KAKA Industrial®

use can be obtained from metal working
books or from the Internet.
UNDERSTANDING SPRINGBACK
Springback, also known as elastic
recovery, is the result of the metal
wanting to return to its original shape
after undergoing compression and stretch.
After the bending leaf is removed from
the metal and the load is released, the
piece part relaxes, forcing the bent
portion of the metal to return slightly to its
original shape. The key to obtaining the
correct bend angle is to over bend the
metal a little and allow it to spring back to
the desired angle. All metals exhibit a
certain amount of spring back.
MATERIAL SELECTION
CAUTION
It must be determined by the customer
that materials being processed through
the machine are NOT potentially
hazardous to operator or personnel
working nearby.
When selecting materials keep these
instructions in mind:
●Material must be clean and dry.
(without oil)
●Material should have a smooth
surface so it processes easily.
●Dimensional properties of material
must be consistent and not exceed the
machine capacity values.
●Chemical structure of material must
be consistent.
●Buy certificated steel from the same
vendor when possible.
LUBRICATION AND MAINTENANCE
WARNING
Maintenance should be performed
on a regular basis by qualified
personnel.
Always follow proper safety precautions
when working on or around any
machinery.
●Check daily for any unsafe conditions
and fix immediately.
●Check that all nuts and bolts are
properly tightened.
●On a weekly basis clean the machine
and the area around it.

Operation Manual W-2416Z
Model W-2416Z
- 10 -
●Lubricate threaded components and
sliding devices.
●Apply rust inhibitive lubricant to all
non-painted surfaces.
Oil Ports
Using an oil can with a good quality #30W
oil, apply 5-6 drops into each of the ports
on both ends of the machine. Repeat
weekly or more often depending on
usage. Wipe off any excess oil.
Note: Proper maintenance can increase
the life expectancy of your machine.
