Additional Safety for Bending Brakes
OVERLOADING HAND BRAKE. Over-loading
this tool can cause injury from flying parts. Do not
exceed the machine capacities.
GLOVES AND GLASSES. Always wear leather
gloves and approved safety glasses when using
this machine.
SECURING BENDING BRAKE. Secure bending
brake to the floor before using. Tipping may occur
during use and the machine could fall, causing
serious injury or property damage.
HEATING METAL. Heating the workpiece with a
torch while it is in the brake will weaken the metal
of the clamping and bending leaves. Do not use a
torch or other similar heating tool near the brake.
METAL EDGES. Sharp edges on sheet metal can
result in severe cuts. Always chamfer and de-burr
sharp sheet metal edges before bending in the
hand brake.
BACK INJURIES. The lifting motion required
to operate this machine is potentially harmful if
proper technique is not used. To avoid back injuries, keep your back vertical and lift with your legs
while raising the bending leaf, and never overexert yourself.
PINCHING. To prevent pinching hazards, lower
the clamping leaf when not in use.
CRUSHING & AMPUTATION INJURIES. The
bending brake can quickly crush or amputate
fingers or hands. Never place fingers or hands
between the clamping and bending leaves.
Like all machinery there is potential danger
when operating this machine. Accidents
are frequently caused by lack of familiarity
or failure to pay attention. Use this machine
with respect and caution to decrease the
risk of operator injury. If normal safety precautions are overlooked or ignored, serious personal injury may occur.
Model G9949 (Mfg. Since 12/00)
TOOLS IN POOR CONDITION. Loose hardware
or cracks could result in sudden, uncontrolled
movements during use. Inspect the bending brake
for any cracked linkage, levers, or loose fasteners.
Correct any problems before use.
No list of safety guidelines can be complete. Every shop environment is different.
Always consider safety first, as it applies
to your individual working conditions. Use
this and other machinery with caution and
respect. Failure to do so could result in
serious personal injury, damage to equipment, or poor work results.

Site Considerations
Physical Environment
Weight Load
The physical environment where your machine
is operated is important for safe operation and
the longevity of its components. For best results,
operate this machine in a dry environment that is
free from excessive moisture, hazardous chemicals, airborne abrasives, or extreme conditions.
Extreme conditions for this type of machinery are
generally those where the ambient temperature
range exceeds 41°–104°F; the relative humidity
range exceeds 20–95% (non-condensing); or the
environment is subject to vibration, shocks, or
bumps.
Refer to the Machine Data Sheet for the weight
of your machine. Make sure that the surface upon
which the machine is placed will bear the weight
of the machine, additional equipment that may be
installed on the machine, and the heaviest workpiece that will be used. Additionally, consider the
weight of the operator and any dynamic loading
that may occur when operating the machine.
Space Allocation
Lighting
Lighting around the machine must be adequate
enough that operations can be performed safely.
Shadows, glare, or strobe effects that may distract
or impede the operator must be eliminated.
Consider the largest size of workpiece that will
be processed through this machine and provide
enough space around the machine for adequate
operator material handling or the installation of
auxiliary equipment. With permanent installations,
leave enough space around the machine to open
or remove doors/covers as required by the maintenance and service described in this manual.
See below for required space allocation.
Children or untrained people
may be seriously injured by
this machine. Only install in an
access restricted location.

Assembly
3.Attach the legs to the brake with the (4) preinstalled M12-1.75 x 40 hex bolts, (8) 12mm
flat washers, and (4) M12-1.75 hex bolts, as
shown in Figure 5.
The Model G9949 is a heavy
machine. Serious personal
injury may occur if safe
moving methods are not
used. To be safe, get assistance and use lifting equipment to move the shipping crate and remove the
machine from the crate.
To assemble the machine:
Note: Make sure the longer portion of the leg
bases are in front of the brake to support the
dynamic forces during operation.
4.Lower the assembly to the ground, then
secure it to the floor with the selected hardware (see Mounting on Page 12 for recommended options).
5.Attach the bending leaf handle with the (4)
pre-installed M10-1.5 x 30 hex bolts and (4)
10mm flat washers, as shown in Figure 6.
1.Unbolt the brake from the angle irons that
secure it to the shipping pallet.

2.Use one of the following methods of raising
the brake to attach the legs:
a. Use four strong people to lift the brake
onto saw horses that can support the
load and are taller than the brake legs.
b. Wrap lifting straps around both ends of
the brake, then attach the straps to a
forklift or other lifting equipment and raise
the brake high enough to attach the legs,
as shown in Figure 5.

Mounting
To prevent the brake from tipping over from the
dynamic forces during operation, the bending
brake must be secured to the floor. Because
floor materials vary, mounting hardware is not
included.
Anchor Studs
The mounting holes in the leg bases will accept
5
⁄ 16" fasteners.
Lag Shield Anchor
and Lag Screw
Bolting to Concrete Floors
Anchor studs and lag shield anchors with lag
screws (see Figure 8) are two popular methods
for anchoring an object to a concrete floor. We
suggest you research the many options and methods for mounting your machine and choose the
best that fits your specific application.
Figure 8. Typical fasteners for mounting to
concrete floors.
NOTICE
Anchor studs are stronger and more permanent alternatives to lag shield anchors;
however, they will stick out of the floor,
which may cause a tripping hazard if you
decide to move your machine.

SECTION 3: OPERATIONS
Operation Overview
The purpose of this overview is to provide 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 the generic nature of this overview, it is
not intended to be an instructional guide. To learn
more about specific operations, read this entire
manual and seek additional training from experienced machine operators, and do additional
research outside of this manual by reading "howto" books, trade magazines, or websites.
To reduce the risk of
serious injury when using
this machine, read and
understand this entire
manual before operating.
To complete a typical operation, the operator
does the following:
1.Adjusts the clamping leaf setback for the
workpiece material.
2.
Makes sure the clamping leaf is parallel to the
clamping block.
3.Puts on personal protective wear and clears
all tools and other objects from the brake and
the surrounding area.
4.Uses the handle to raise the clamping leaf and
slides the workpiece between the leaves.
5.
Slowly lowers the clamping leaf as the
workpiece is correctly positioned for the
bend.
6.
With the clamping leaf securing the workpiece,
raises the bending leaf handle to make the
bend to the desired angle.
7.
Completely lowers the bending leaf handle,
raises the clamping leaf, and removes the
workpiece.
Damage to your eyes,
hands, or body could occur
when handling sheet metal.
Always wear safety glasses,
heavy leather gloves, and
other protective wear when
operating this machine.
If you have never used this type of machine
or equipment before, We strongly recommend that you read books, review
industry trade magazines, or get formal
training before beginning any projects.
Regardless of the content in this section,
Grizzly Industrial will not be held liable for
accidents caused by lack of training.

Basic Controls
Adjusting Setback
Refer to Figures 9–10 and the following descriptions to become familiar with the basic controls of
the bending brake.
Setback (A in Figure 11) is the distance from the
forward edge of the clamping leaf to the front edge
of the clamping block—this is where the bend will
be. The setting of this distance is determined by
the workpiece gauge and the bend radius.
Setback Cam. Adjusts the setback of the clamping leaf for the workpiece thickness and desired
crease radius.

•
For material 22 gauge and thinner, the setback (A) is adjusted to 1 1⁄2 times the workpiece
thickness (B).
•
For material thicker than 22 gauge, the setback is adjusted to 2 times the workpiece
thickness.
•Tempered workpieces or ones with folded
edges or joints will need a larger setback.
You must adjust the correct amount of setback for the workpiece material, or brake
damage may occur.
Bending Leaf Handle. Use to pivot the bending
leaf up to create the crease.

To adjust the setback:
1.Loosen the setback cam hex nuts on both
sides of the brake (see Figure 12).
Setback Cam
& Hex Nut
Figure 12. Setback cam and hex nut.
2.Rotate both setback cams in even amounts
to adjust the setback distance.
3.
Bending operations require that the setback is
properly set (see Adjusting Setback on Page
14) and the distance between the clamping leaf
and clamping block is even along the full length
(see Clamping Leaf Parallelism on Page 20 for
detailed instructions).
The dynamic forces of operation could
cause the brake to tip over and cause injury
or property damage. Do not operate the
Model G9949 unless it has been properly
secured to the floor.
To perform a basic bending operation:
1.
Mark a line on the workpiece where the bend
should be.
Note: Because the cams are eccentric, turning them a full turn will bring the clamping leaf
back to its original position.
2.Properly adjust the clamping leaf setback for
the workpiece material (refer to Adjusting

Make sure the clamping leaf edge is parallel
with the bending leaf along the entire length
(see Figure 13). This will prevent the bend
from being distorted.
3.Raise the clamping leaf and insert the
workpiece between the clamping leaf and
clamping block.

Bending Allowance
When metal deforms to make a bend, there is a
certain amount added to the outside dimension
and subtracted from the inside dimension. This is
the bend allowance (see Figure 16).

2.As you perform the bend that is to be repeated, hold the bending leaf handle at the position of the completed bend, then rotate the
work stop down until the stop rod contacts the
bending leaf handle (see Figure 18).
Figure 16. Bend allowance illustration.
To bend metal objects accurately, you need to
consider the total length of each bend, especially
when more than one bend is required.
There are numerous formulas and calculators
available to predict the bend allowance for a given
bend—these can be found in books and on the
internet. Bend allowances accurate enough for
average use may also be found in metalworking
handbooks.

SECTION 5: MAINTENANCE
Schedule
Lubrication
For optimum performance from your machine,
follow this maintenance schedule and refer to any
specific instructions given in this section.
Lubricating the Model G9949 consists of applying
lubricant to the setback cams and bushings.
Daily Check:
•Loose mounting bolts.
•Damaged dies
•
Any other unsafe condition.
Weekly Maintenance:
•
Clean machine.
•
Lubricate setback cams and bushings.
Oiling Locations
Apply several drops of SAE 30 or equivalent
oil from an oil can into the locations shown in
Figure 23. Move each component back and forth
several times to disperse the oil, then wipe off
excess oil. Be sure to lubricate the locations on
both sides of the machine.
Cleaning &
Protecting
Cleaning the Model G9949 is relatively easy.
Periodically wipe down the machine to remove
dust and oil.
Protect the unpainted surfaces on the machine by
wiping them clean after every use—this ensures
rust-promoting debris does not remain on bare
metal surfaces.
Figure 23. Oil locations (right side shown).
Keep the machine rust-free with regular applications of products like Boeshield ® T-9 (see
Accessories on the previous page for more
options from Grizzly).

Clamping Leaf
Parallelism
Clamping
Leaf
A
The clamping leaf must be parallel to the clamping block in height to ensure accurate bending
results. The height of the clamping leaf above the
clamping block is controlled by the turnbuckles on
both ends of the brake (see Figure 24).

Wrench 24mm.....................................................2
4.Adjust the turnbuckle middle nuts to raise or
lower the clamping leaf until the leaf edge
touches the clamping block evenly along its
full length.
To adjust the clamping leaf parallelism:
5.
1.Lower the clamping leaf to the clamping block
until it is just touching the surface but not
exerting clamping force.
6.Repeat Step 2 to ensure the clamping leaf is
parallel to the clamping block.
2.
Without turning the turnbuckle middle nuts,
re-tighten all lock nuts.
Examine the distance between the clamping leaf and the clamping block along its full
length (refer to A in Figure 25).
—If the clamping leaf edge touches the
clamping block evenly along its full length,
then the clamping leaf is parallel to the
clamping block and no further action is
necessary.
—If the clamping leaf edge does not touch
the clamping block evenly along its full
length, continue with the next step.
