alcohol, when tired, or when distracted.
Model T10718 (Mfg. Since 1/13)
ELECTRICAL EQUIPMENT INJURY RISKS. You
can be shocked, burned, or killed by touching live
electrical components or improperly grounded
machinery. To reduce this risk, only allow qualified
service personnel to do electrical installation or
repair work, and always disconnect power before
accessing or exposing electrical equipment.
DISCONNECT POWER FIRST. Always disconnect machine from power supply BEFORE making
adjustments, changing tooling, or servicing machine.
This prevents an injury risk from unintended startup
or contact with live electrical components.
EYE PROTECTION. Always wear ANSI-approved
safety glasses or a face shield when operating or
observing machinery to reduce the risk of eye
injury or blindness from flying particles. Everyday
eyeglasses are NOT approved safety glasses.
-5-
WEARING PROPER APPAREL. Do not wear
clothing, apparel or jewelry that can become
entangled in moving parts. Always tie back or
cover long hair. Wear non-slip footwear to reduce
risk of slipping and losing control or accidentally
contacting cutting tool or moving parts.
HAZARDOUS DUST. Dust created by machinery
operations may cause cancer, birth defects, or
long-term respiratory damage. Be aware of dust
hazards associated with each workpiece material. Always wear a NIOSH-approved respirator to
reduce your risk.
HEARING PROTECTION. Always wear hearing protection when operating or observing loud
machinery. Extended exposure to this noise
without hearing protection can cause permanent
hearing loss.
REMOVE ADJUSTING TOOLS. Tools left on
machinery can become dangerous projectiles
upon startup. Never leave chuck keys, wrenches,
or any other tools on machine. Always verify
removal before starting!
USE CORRECT TOOL FOR THE JOB. Only use
this tool for its intended purpose—do not force
it or an attachment to do a job for which it was
not designed. Never make unapproved modifications—modifying tool or using it differently than
intended may result in malfunction or mechanical
failure that can lead to 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 BEFORE
operating machine.
-6-
FORCING MACHINERY. Do not force machine.
It will do the job safer and better at the rate for
which it was designed.
NEVER STAND ON MACHINE. Serious injury
may occur if machine is tipped or if the cutting
tool is unintentionally contacted.
STABLE MACHINE. Unexpected movement during operation greatly increases risk of injury or
loss of control. Before starting, verify machine is
stable and mobile base (if used) is locked.
USE RECOMMENDED ACCESSORIES. Consult
this owner’s manual or the manufacturer for recommended accessories. Using improper accessories will increase the risk of serious injury.
UNATTENDED OPERATION. To reduce the
risk of accidental injury, turn machine OFF and

Additional Safety for Pan & Box Brakes
CRUSHING & AMPUTATION INJURIES. The
brake can quickly crush or amputate fingers,
hands, or body parts. Never place fingers, hands,
or body parts between or near the clamping fingers and bending blocks during operation.
SECURING BRAKE. Before using, secure the
brake to the floor so it can support the weight and
dynamic forces involved in bending sheet metal.
Otherwise, the brake may unexpectedly move
or tip during operation, causing serious injury or
property damage.
COMFORTABLE BODY POSITION. The required
body motion to operate the brake can result in
operator injury over time if proper ergonomics are
not used during operation. Always keep your body
centered with the machine and your back straight
when using the foot pedal.
HEATING METAL. Heating the workpiece with a
torch or welding it while clamped in the brake may
weaken the fingers, blocks, and frame. Do not use
a torch, welder, or other similar heating tool near
the brake.
TOOLS IN POOR CONDITION. Using this tool
with loose hardware or damaged components
could result in sudden, unexpected movements
during use. Inspect the brake for cracked components, damaged linkage, levers, or loose fasteners. Correct any problems before use.
CAPACITY. Exceeding the capacity of the brake
may result in sudden breakage that ejects dangerous metal debris at the operator or bystanders, or
causes machine damage. Only use sheet metal
that is within the rated capacity of this brake (refer
to the Machine Data Sheet on Page 4).
LEAVING UNATTENDED. To reduce the risk of
crushing or amputation injuries with children or
visitors, lower the clamping leaf and lock the foot
pedal down when not in use.
FOOTING. This brake requires you to apply moderate force to the foot pedal while bending. If your
foot slips, you could fall down and be injured.
Always stand with one foot comfortably on the
floor during operation. Never use both feet on
the foot pedal or jump on it. Never have one foot
under the foot pedal during operation.
METAL EDGES. Sharp edges on sheet metal can
result in severe cuts. Always wear leather gloves
and chamfer/de-burr sharp sheet metal edges.
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 T10718 (Mfg. Since 1/13)
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.

Cleanup
Cleaning Blocks
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.
The clamping fingers and bending blocks
(Figure 1) are coated with rust preventative that
must be removed before beginning operation.
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.
Bending
Block
Clamping
Finger
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.
Figure 1. Bending finger and clamping block
removed for cleaning.
Although the rust preventative was applied only
to the visible surfaces of the blocks, some may
have worked in between and underneath them.
We recommend that you remove all of the blocks
to thoroughly clean them.
If you do remove the blocks, properly align them
as described in the Aligning Fingers & Blocks
subsection on Page 17 after re-installing.
NOTICE
Avoid chlorine-based solvents, such as
acetone or brake parts cleaner, that may
damage painted surfaces.
Model T10718 (Mfg. Since 1/13)

Site Considerations
Physical Environment
Weight Load
The physical environment where the machine
is operated is important for safe operation and
longevity of 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 is outside 41°–104°F; the relative humidity
range is outside 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.

Model T10718 (Mfg. Since 1/13)
Lifting & Placing
HEAVY LIFT!
Straining or crushing injury
may occur from improperly
lifting machine or some of
its parts. To reduce this risk,
get help from other people
and use a forklift (or other
lifting equipment) rated for
weight of this machine.
Mounting
The Model T10718 is shipped fully assembled.
However, due to the significant dynamic forces on
the brake during operation, you must secure it to
the floor to prevent tipping. Because floor materials vary, floor mounting hardware is not included.
Anchor studs and lag shield anchors with lag
screws (Figure 4) are two popular methods for
anchoring the brake 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.
To lift and place the brake:
1.
Move the brake to the installation location
while it is still on the shipping pallet.
2.
Unbolt the brake from the shipping pallet.
3.
Make sure the foot pedal is locked in the
down position.
4.
Attach the safety hooks and chains to the
side lifting brackets, as shown in Figure 3,
then connect the chains to the fork lift.

5.
With the help of another person on the ground
to prevent the brake from swinging or rocking
when lifted, raise the brake just enough to
clear the shipping pallet, then remove the pallet.
6.
Lower the brake into place and mount it to the
floor as recommended in the next subsection.
Model T10718 (Mfg. Since 1/13)
-11-
Leveling
Leveling the brake helps the leafs and other castiron components remain straight and flat during
the lifespan of the machine. Components on an
unleveled machine may slowly twist due to the
dynamic loads placed on the machine during
operation, which will negatively affect the ability of
the brake to produce accurate bends.
Loosening Work
Stop
The clamping cap screw on the work stop collar
(see Figure 6) was tightened at the factory to
keep the bending leaf from moving. Before beginning operation, use an 8mm hex wrench to loosen
the clamping cap screw so that the bending leaf
can rotate through its full arc.
If needed, use metal shims between the base and
the floor when leveling the machine.
For best results, use a precision level that is at
least 12" long and sensitive enough to show a
distance movement when a 0.003" shim (approximately the thickness of one sheet of standard
newspaper) is placed under one end of the level.

To complete a typical operation, the operator
does the following:
1.
Examines the workpiece to make sure it is
suitable for bending.
2.
If required for the operation, adjusts the
clamping finger and bending block spacing.
3.
Adjusts the clamping pressure for the
workpiece thickness.
4.
Correctly adjusts the setback.
5.
Puts on safety glasses, leather boots, and
leather gloves.
6.
Properly positions the workpiece underneath
the clamping fingers and locks the foot pedal
in the down position to secure the workpiece.
7.
Using proper body position and both hands,
raises the bending leaf to form the correct
bend angle.
8.
Lowers the bending leaf, then unlocks raises
and the foot pedal to release and remove the
workpiece.
If you are not experienced with this type
of machine, WE STRONGLY RECOMMEND
that you seek additional training outside of

Basic Controls
Bend Allowance
Use Figure 7 and following descriptions to become
familiar with the basic controls of the brake.
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.
Pressure
Adjustment
Knob
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.

& Lock
Figure 7. Basic controls.
Pressure Adjustment Knobs: Adjust the clamping pressure for different workpiece thicknesses.
Setback Adjustment Knobs: Adjust the distance
of the bending blocks from the clamping fingers.
Bending Leaf Handle: Allows the operator to lift
the bending leaf to produce the bend.
Foot Pedal & Lock: Controls the action of the
clamping leaf.
Sharp edges of sheet metal
can easily cut fingers,
hands, or other body parts.
Always wear leather gloves
when handling sheet metal,
and always chamfer and
debur the edges.
Exact allowances can only be obtained by trial due
to differences in sheet metal hardness, whether
the bend is with or across the grain, 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
bending blocks and the clamping fingers to properly make the bend (see Figure 8). A number of
factors determine the correct setback distance,
such as bend allowance, bend radius, and material thickness.
There are many sources to help you calculate the
correct setback for your operation, such as metalworking handbooks, the internet, or experienced
sheet metal workers.

To adjust the setback:
1.
Loosen the hex bolts (see Figure 9) on each
side of the bending leaf.
Hex Bolt

Graduated
Dial
When securing the workpiece with the foot pedal,
the correct clamping pressure depends on the
workpiece thickness. The ideal pressure locks the
workpiece firmly in position between the clamping
fingers and base without excessive compression
that could damage the workpiece or brake.
Rotate one pressure adjustment knob (see
Figure 10) a small amount, then rotate the other
knob the same amount and direction. This prevents the clamping leaf from binding on the shafts
and keeps it parallel with the clamping base.

We recommend that the foot pedal always be
locked down after positioning the workpiece and
before making the bend. This will help ensure
the workpiece stays in the proper position during
bending.
Make sure the clamping pressure is correctly adjusted for the workpiece thickness
to prevent workpiece or machine damage
when the foot pedal is fully depressed.

Spacing Fingers &
Blocks
Aligning Fingers &
Blocks
The clamping and bending blocks can be spaced
apart for clearance when making pans or boxes.
This requires removing one or more sets of blocks
and spacing the others to match the width of your
pan or box. See Figure 13 for an example.
To help ensure the bend is even along its length,
the clamping fingers and bending blocks must be
properly aligned with one another.
T-Nut
Tool Needed
Qty
Hex Wrench 8mm............................................... 1
Aligning Clamping Fingers
1.
Loosen the cap screws that secure the finger,
but do not remove them.
2.
Apply upward pressure to the finger until it
stops, then re-tighten the cap screws.
3.
Examine the entire row of clamping fingers
to make sure the upper edges are all aligned
with one another (Figure 14). If necessary,
repeat Steps 1–2 until they are.
Figure 13. Example of block spacing.
The T-nuts under the fingers and blocks that
secure them can be moved along their slots to
allow for any spacing configuration required.
As you space the fingers and blocks, make sure
that you properly align them, as described in the
next subsection.

Aligning Bending Blocks
The bending blocks are aligned in a similar manner as the clamping fingers except you apply
downward pressure (or toward the operator, if the
bending leaf is raised) to align the block edges
with one another.

Lubrication
Clamping Leaf Slide Shafts
Oil Type......Grizzly T23963 or ISO 32 Equivalent
Oil Amount...................................... 1 or 2 Squirts
Lubrication Frequency.................................. Daily
The slide shaft ball oilers (see Figure 25) provide
lubrication to the sliding surfaces between the
shafts and the frame.
Ball
Oiler
Sliding Surface
Figure 25. Clamping leaf slide shaft ball oiler.
Only lubricate these ball oilers with a pump-type
oil can that has a plastic or rubberized cone tip.
Do not use oil cans with a metal needle or lance
tip, as they can push the ball too far into the oiler,
break the spring seat, and lodge the ball in the oil
galley.
When lubricating the ball oilers, first clean the outside surface to remove any dust or grime. Push
the tip of the oil can nozzle against the ball oiler
to create a hydraulic seal, then pump the oil can
once or twice to add oil.

The bending leaf rotates around the pivot shaft on
bushings that require lubrication. Use an oil can to
add lubricant to the hole shown in Figure 26 (one
on each side of the bending leaf), then raise and
lower the bending leaf several times to distribute
the lubricant.
Raise the bending leaf until it is parallel with the
floor, then add one drop of oil to the setback shaft
locations shown in Figure 28. Use the setback
adjustment knobs to move the bending leaf back
and forth along the shafts to distribute the lubricant.
