PREPARATION/CLEANING

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 clean the machine thoroughly. 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

• Safety glasses &disposable gloves

• Plastic paint scraper (optional)

Basic steps for removing rust preventative

1. Coat the rust preventative with a liberal amount of cleaner/degreaser,
then let it soak for 5-10 minutes.

2. Wipe the surfaces. If your 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.

3. Repeat Steps 2-3 as necessary until clean, then coat all unpainted surfaces
with a quality metal protectant to prevent rust such as light oil.

CLEANING THE FINGERS

Although rust preventative was applied
only to the visible surfaces of the
clamping fingers (see Figure 3), some
may have worked in between and
underneath them. We recommend you
remove all clamping fingers and
thoroughly clean them.

To remove the clamping fingers, move
the clamping handles toward back of
the machine to raise the clamping leaf,
then loosen the cap screws and
remove the clamping fingers and toe
clamps (see Figure 4).

After all the fingers have been
cleaned, coat them liberally with a
metal protectant 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 fingers are properly
aligned (refer to Aligning Fingers on page 11).

BENCH MOUNTING

WORKBENCH LOAD

Refer to the product specification on
page 2 for the weight and footprint
specifications of your machine. Some
workbenches may require additional
reinforcement to support the weight of
the machine and workpiece materials.

PLACEMENT LOCATION

Consider anticipated workpiece sizes
and additional space needed for
auxiliary stands, work tables, or other
machinery when establishing a
location for this machine in the workshop. Below is the minimum amount of
space needed for the machine.

WARNING: LIFTING HEAVY MACHINERY OR PARTS WITHOUT PROPER
ASSISTANCE OR EQUIPMENT MAY RESULT IN STRAINS, BACK INJURIES,
CRUSHING INJURIES OR PROPERTY DAMAGE.

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.

• Number of mounting holes = 4

• Diameter of mounting hardware

needed. 3/8”.

Another option is a "direct mount" (see
example) where the machine is
secured directly to the workbench with
lag screws and washers.

SPACING THE 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.

TOOLS NEEDED

Hex wrench 8mm

TO SPACE CLAMPING FINGERS:

1. Loosen the cap screws from each
finger you need to remove.

2. Remove the fingers and toe clamps
from the clamping leaf, as shown in
Figure 8, and set them aside.

NOTE: You may need to mix and

match finger widths to match
the inside width of your pan or
box.

3. Align the remaining fingers and
tighten the cap screws.

Parts & Service: 020 8988 7400 / E-mail: [email protected] or [email protected]

ALIGNING THE CLAMPING FINGERS

To help ensure the bend is even along its length, the clamping fingers must be
parallel with the clamping surface and bending block.

TOOLS NEEDED

Hex wrench 8mm

TO ALIGN CLAMPING FINGERS:

1. Lower the clamping leaf until the clamping fingers are just touch the
clamping surface (see Figure 9)

2. Look closely along the bottom
edge of each finger to determine if
any are out of alignment with the
clamping surface and bending
leaf, as shown in Figure 9.

3. Loosen the cap screw on a
misaligned finger just enough to
move it up or down.

4. Align the finger parallel with the
clamping surface and bending
block and then tighten the cap
screw.

ADJUSTING SETBACK

NOTE: Include the thickness of folded edges or joints when determining

the proper setback or the equipment may be damaged.

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 10. The setback distance is determined by
the gauge of the workpiece material and the desired radius of the bend.

Setback is normally adjusted 150% the
thickness of 22 gauge and thinner
workpieces, and 200% the thickness of
a workpieces thicker than 22 gauge.

TO ADJUST SETBACK

1. Determine setback required for
bend.

2. Raise the clamping fingers about
12mm off the clamping surface.

3. Loosen the cap screws that secure
the setback wheels (see Figure 11).

4. Rotate both setback wheels until
the desired setback distance is
achieved.

NOTE: Setback wheels are eccentric.

Turning them one full turn will
bring the clamping leaf back
to its original position.

If you find it hard to turn the setback
wheels with your fingers, insert a hex
wrench into the holes on the edges of
the wheels to gain leverage.

5. Lower the clamping fingers onto the clamping surface and check the
setback distance.

6. If necessary, repeat Steps 1-4 until the desired setback is achieved.

7. Check the finger alignment (refer to Aligning Fingers on Page 11).

ADJUSTING CLAMPING PRESSURE

Clamping pressure must be properly
adjusted for different workpiece
thicknesses. The ideal pressure will have
medium resistance at the clamping
handles and will lock the workpiece
into position easily.

Pressure is adjusted by rotating the
adjustment nuts on the clamping
pressure adjustment rods (see Figure

12). These are located on both ends of
the machine.

TOOLS NEEDED

Open ended wrench 17/19mm

1. Lower the clamping leaf so the clamping fingers just touch the workpiece.

It is best if the workpiece used in this procedure is same width as the machine.
If not, place two pieces of metal of the same thickness as the workpiece on
each end of machine.

NOTE: If the clamping handles are at 10 o'clock (viewed from the right

end) and 2 o'clock (viewed from left end) position, then the
clamping pressure is suitable for the workpiece. Proceed to Step

4.

NOTE: If the 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, then the clamping pressure is not suitable for the
workpiece. Proceed to Step 2.

2. Loosen the adjustment nuts (see Figure 12) and turn both sets up or down
until the clamping handles are in the 10 and 2 o'clock position when the
clamping fingers just touch the workpiece.

3. Tighten the adjustment nuts to secure in position.

4. Make sure the clamping pressure is even on both ends of the machine by
raising one end and testing the clamping action of other end. The
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 the handle stop (see Figure

12).
