Another option is a "direct mount" (see example
below) where the machine is secured directly to
the workbench with lag screws and washers.
The base of this machine has mounting holes
that allow it to be fastened to a workbench or
other mounting surface to prevent it from moving
during operation and causing accidental injury or
damage.
The strongest mounting option is a "Through
Mount" (see example below) where holes are
drilled all the way through the workbench—and
hex bolts, washers, and hex nuts are used to
secure the machine in place.
Cleanup
The unpainted surfaces of your machine are
coated with a heavy-duty rust preventative that
prevents corrosion during shipment and storage.
This rust preventative works extremely well, but it
will take a little time to clean.
Be patient and do a thorough job cleaning your
machine. The time you spend doing this now will
give you a better appreciation for the proper care
of your machine's unpainted surfaces.
There are many ways to remove this rust preventative, but the following steps work well in a wide
variety of situations. Always follow the manufacturer’s instructions with any cleaning product you
use and make sure you work in a well-ventilated
area to minimize exposure to toxic fumes.
Before cleaning, gather the following:
• Disposable rags
• Cleaner/degreaser (WD•40 works well)
• Safety glasses & disposable gloves
• Plastic paint scraper (optional)

1.
2. Coat the rust preventative with a liberal
amount of cleaner/degreaser, then let it soak
for 5–10 minutes.
Wipe off the surfaces. If your cleaner/
3.
degreaser is effective, the rust preventative
will wipe off easily. If you have a plastic paint
scraper, scrape off as much as you can first,
then wipe off the rest with the rag.
Repeat Steps 2–3 as necessary until clean,
4.
then coat all unpainted surfaces with a quality
metal protectant to prevent rust.
NOTICE
Avoid harsh solvents like acetone or brake
parts cleaner that may damage painted surfaces. Always test on a small, inconspicuous location first.

Assembly
The machine must be fully assembled before it
can be operated. Before beginning the assembly
process, first clean any parts that are covered or
coated in rust preventative.
To assemble machine:
Bend Allowance
When a bend is made in sheet metal, the inside
surface of the bend compresses and the outside
surface stretches. To bend metal objects accurately, you need to consider the length of each
bend, especially when more than one bend is
required. This is called bend allowance.

holes (see Figure 5).
Bending Lever

Breaker Bar Hole
(1 of 2)
Figure 5. Installing bending lever.
The bend allowance is added to the sum of the
outside dimensions of the workpiece flat surfaces
to obtain the overall length and width of the blank
needed to make a particular part.
Exact allowances can only be obtained by trial
due to differences in sheet metal hardness, how
the workpiece is positioned, and difficulties in
making an exact bend radius. Formulas for calculating the bend allowance can be found in metalworking handbooks or the internet.

Adjusting Setback
Setback is the required distance between the
breaker bar and the clamping leaf to properly
make the bend (see Figure 7). A number of factors determine the correct setback distance, such
as bend allowance, bend radius, and material
thickness.

To adjust setback:
. Use calipers to measure distance between
1
both ends of clamping leaf and where
workpiece will contact breaker bar (see
Figures 8–9).
— If distances measured in Step 1 are equal
and correct for operation, no adjustment is
required.
— If distances measured in Step 1 are not
equal or not correct for operation, proceed
to Step 2.

Typical Bending Operation
Eye injury hazard! Always
wear safety glasses when
Use the following steps to perform a typical bend
on a workpiece.
Tip: During a bending operation, workpiece scor-
ing may occur. To avoid these marks, keep both
the clamping leaf and the bending leaf free of
burrs, and adhere a strip of tape on the workpiece
over the area that will be bent.
Release both clamps by pushing handles

away from you (see Figure 11).

Do not operate unless machine has been
securely clamped or mounted to workbench.
Failure to secure machine before use could
result in crushing injuries.
Only bend stock that falls within bending
capacity of this machine. Stock thicker than
20 gauge will damage machine when bent.

Radius Bending
Eye injury hazard! Always
Radius bending is most commonly used to make
cylinders and cones, both of which are formed by
making a series of small, closely-spaced bends in
the workpiece.
For cylinders, the bends are evenly spaced and
parallel to the workpiece edges while cones have
a series of uneven bends that are not parallel to
the edges (see Figure 15).
Uneven Bends
Even Bends
Pan & Box Bending
When bending a piece of flat metal into a box,
you will need to make multiple bends on the same
workpiece. While you will use the same procedure
as described in Typical Bending Operation on
Page 5, you will also need to consider the clearance needed to clamp and bend the remaining
sides of the workpiece without interfering with
your first bend (see Figure 17).

Use this information as well as the steps listed in
Typical Bending Operation beginning on Page

If you cannot get your bends close enough
together for your operation, remove the fasteners
shown in Figure 16 to remove the bending leaf
from the breaker bar. Removing the bending leaf
will decrease the overall bending capacity but will
also allow for very tight tolerances.

Lubrication
When lubricating this machine, first clean the
components. This step is critical because grime
and dust build up on lubricated components,
which makes them hard to move. Simply adding
more lubricant will not result in smooth moving
parts.
Lubricate the pivot points indicated in Figure 24
with a few drops of light machine oil whenever you
notice resistance when bending.

handling sheet metal. Chamfer and deburr sharp metal edges.
3. Securely mount machine to stable workbench or stand before use.
4. Do not exceed rated capacity or bend material machine is not intended to bend.
5. Do not use breaker bar to gain leverage.
6. Keep hands/fingers clear of clamping area when operating.
