mechanical failure that leadsto serious
personal injury or death!
AWKWARD POSITIONS.
Keep proper footing and
balance at all times when operating machine.
Do not overreach! Avoid awkward hand
positions that make workpiece control difficult
or increase the risk of accidental injury.
CHILDREN & BYSTANDERS.
Keep children and
bystanders at a safe distance from the work
area. Stop using machine if they become a
distraction.
GUARDS & COVERS.
Guards and covers reduce
accidental contact with moving parts or flying
debris—make sure they are properly installed,
undamaged, and working correctly.
FORCING MACHINERY. Do not force machine. It
will do the job safer and better at the rate for

unpacking or they are pre-installed at the factory.

INJURY HAZARD! Untrained
users can injure themselves
with this machine. Restrict
access to machine when
you are away, especially if
it is installed where chil-
dren are present.
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)
Basic steps for removing rust preventative:
1.
Put on safety glasses.
2.
Coat the rust preventative with a liberal
amount of cleaner/degreaser, then let it
soak for 5–10 minutes.
3.
Wipe off the surfaces. If your cleaner/
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.
4.
Repeat Steps 2–3 as necessary until clean,
then coat all unpainted surfaces with a
quality metal protectant to prevent rust.
Avoid chlorine-based solvents, such as
acetone or brake parts cleaner, that may
damage painted surfaces.

Cleaning Fingers
Although rust preventative was applied only to the visible
surfaces of the clamping fingers (see Figure 7), some
may have worked in between and underneath them. We
recommend you remove all the clamping fingers and
thoroughly clean them.
To remove the clamping fingers, move the clamping
handles (see Figure 7) toward the back of the machine
to raise the clamping leaf, then loosen the cap screws
and remove the clamping fingers and toe clamps (see
Figure 8).
After all the fingers have been cleaned, coat them
liberally with a metal protectant (see Page 23), and clean
the finger guide on the clamping leaf. Place the fingers
along the guide on the clamping leaf, align the toe clamps
to catch the bottom of the clamping leaf, and tighten the
cap screws enough so the fingers will not fall off. When
done, make sure the fingers are properly aligned (refer to
Aligning Fingers on Page 16).

OPERATIONS
OPERATIONS
General
This machine will perform many types of operations
that are beyond the scope of this manual. Many of these
operations can be dangerous or deadly if performed
incorrectly.
The instructions in this section are written with the
understanding that the operator has the necessary
knowledge and skills to operate this machine. If at any
time you are experiencing difficulties performing any
operation, stop using the machine!
The overview below provides the novice machine operator
with a basic understanding of how the machine is used
during operation, so the machine controls/components
discussed later in this manual are easier to understand.
Due to its generic nature, this overview is
NOT intended
to be an instructional guide.
To complete a typical operation, the operator does the
following:
1. Examines workpiece to make sure it is suitable for
bending.
2. If required for the operation, adjusts clamping finger
spacing.
3. Positions counterweight depending on workpiece
thickness.
4. Adjusts clamping pressure for workpiece thickness.
5. Correctly adjusts setback.
6. Puts on safety glasses, leather boots, and leather
gloves.
7. Properly positions workpiece underneath clamping
fingers and lowers clamping leaf to secure
workpiece.
8. With body square to brake and using both hands,
raises bending leaf to form correct bend angle.
9. Lowers bending leaf and removes workpiece.

Model M1118 (For Machines Mfd. Since 09/21)
OPERATIONS
Spacing Fingers
The clamping fingers can be spaced apart for clearance
when making pans or boxes. This requires removing
one or more of the fingers, so that you can space the
others to match the inside width of your pan or box (see
Figure 12).
Tool Needed: Qty
Hex Wrench 8mm ...............................................1
To space clamping fingers, do these steps:
1. Loosen cap screw on each finger you need to
remove.
2. Remove fingers and toe clamps from clamping leaf,
as shown in Figure 12, and set them aside.
Note: You may need to mix and match finger widths
or space fingers appropriately to match the inside
width of your pan or box.
3. Align remaining fingers and tighten cap screws.
Aligning Fingers
To help ensure the bend is even along its length, the
clamping fingers must be parallel with the clamping
surface and bending block.
Tool Needed: Qty
Hex Wrench 8mm ...............................................1
To align clamping fingers, do these steps:
1. Lower clamping leaf until clamping fingers just touch
clamping surface (see Figure 13).
2. Look closely along bottom edge of each finger to
determine if any are out of alignment with clamping
surface and bending block, as shown in Figure 13.
3. Loosen cap screw on misaligned finger just enough
to move it up or down.
4. Align finger parallel with clamping surface and
bending block, and then tighten cap screw.

OPERATIONS
Adjusting Setback
Before you begin any bending operation, consider
the differences of sheet metal gauges when trying to
achieve either sharp or rounded bends, and allow for the
differences by adjusting the setback.
Setback is the distance from the forward edge of the
fingers to the edge of the bending leaf, as shown in
Figure 14. The setback distance is determined by the
gauge of the workpiece material and the desired radius of
the bend.
Setback is normally adjusted 11⁄2times the thickness
of 22 gauge and thinner workpieces, and two times the
thickness of workpieces thicker than 22 gauge. M1118
material gauge capacities are listed in the Machine
Specifications on Page 3.
Tool Needed: Qty
Hex Wrench 6mm ...............................................1
To adjust setback, do these steps:
1. Determine setback required for bend.
2. Raise clamping fingers about 1⁄2" off of clamping
surface (see Figure 14, A).
3. Loosen cap screws securing setback wheels (see
Figure 15).
4. Rotate both setback wheels until desired setback
distance is achieved.
Note: Setback wheels are eccentric. Turning them
one full turn will bring clamping leaf back to its
original position.
Tip: If you find it hard to turn setback wheels with
your fingers, insert a hex wrench into the holes on
edges of wheels to gain leverage.
5. Lower clamping fingers onto clamping surface and
check setback distance.
6. If necessary, repeat Steps 2–4until desired setback
is achieved.
7. Check finger alignment (refer to Aligning Fingers on
Page 16).

workpiece thicknesses. The ideal pressure will have
medium resistance at the clamping handles, and will
lock the workpiece into position easily—much like a
pair of Vice-Grips®. Pressure is adjusted by rotating the
adjustment nuts on the clamping pressure adjustment
rods (see Figure 16).

To adjust clamping pressure, do these steps:
1. Lower clamping leaf so clamping fingers just touch
workpiece.
Tip: It is best if the workpiece used in this
procedure is same width as pan and box brake. If
not, place two pieces of metal of same thickness as
workpiece on each end of brake.
—If clamping handles are at 10 o'clock (viewed from
right end of brake) and 2 o'clock (viewed from
left end of brake) position, clamping pressure is
suitable for workpiece. Proceed to Step 4.
—If clamping handles are not at 10 o'clock (viewed
from right end of brake) and 2 o'clock (viewed
from left end of brake) position, clamping pressure
is not suitable for workpiece. Proceed to Step 2.
2. Loosen adjustment nuts (see Figure 16) and turn
both sets up or down until clamping handles are in
10 and 2 o'clock positionswhen clamping fingers just
touch workpiece.
3. Tighten adjustment nuts to secure position.
4. Make sure clamping pressure is even on both ends of
brake by raising one end and testing clamping action
of other end. Clamping action should be same on
both ends.
5. If necessary, repeat Steps 1–4 until proper clamping
pressure is achieved.
Note: Proper clamping pressure is achieved when
the clamping handle "snaps" (or locks) into position
against handle stop (see Figure 16).
