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

Additional Safety for Pan & Box Brakes
Fingers can be broken or severely pinched if caught between clamping fingers and bending
blocks during operation. Severe cuts can occur from sliding along or pushing against sharp
workpiece edges. To minimize risk of injury, anyone operating this machine MUST completely
heed the hazards and warnings below.
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.
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.
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.
METAL EDGES. Sharp edges on sheet metal can
result in severe cuts. Always wear leather gloves
and chamfer/de-burr sharp sheet metal edges.
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.
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).
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.
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 may result in serious personal injury or property damage.

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)

Anchoring to Floor
Anchoring machinery to the floor prevents tipping
or shifting and reduces vibration that may occur
during operation, resulting in a machine that runs
slightly quieter and feels more solid.
If the machine will be installed in a commercial or
workplace setting, or if it is permanently connected (hardwired) to the power supply, local codes
may require that it be anchored to the floor.
If not required by any local codes, fastening the
machine to the floor is an optional step. If you
choose not to do this with your machine, we recommend placing it on machine mounts, as these
provide an easy method for leveling and they have
vibration-absorbing pads.
Lag shield anchors with lag screws (see below)
are a popular way to anchor machinery to a concrete floor, because the anchors sit flush with the
floor surface, making it easy to unbolt and move
the machine later, if needed. However, anytime
local codes apply, you MUST follow the anchoring
methodology specified by the code.
Leveling
Number of Mounting Holes ............................ 4
Diameter of Mounting Hardware
.................1⁄2"
Anchoring to Concrete Floors
Leveling the brake helps the leafs and other
cast-iron components remain straight and flat
during the lifespan of the machine. Components
on an unlevel 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.
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.

Spacing Fingers &
Aligning Fingers &
Blocks
The clamping fingers and bending blocks can be
spaced apart for clearance when making pans or
boxes. This requires removing one or more sets of
fingers or blocks and spacing the others to match
the width of your pan or box. See Figure 11 for
an example.
T-Nut
Blocks
To help ensure the bend is even along its length,
the clamping fingers and bending blocks must be
properly aligned with one another.
2. Apply upward pressure to clamping finger
until it stops, then re-tighten cap screw(s).
Examine entire row of clamping fingers to
3.
make sure upper edges are all aligned with
one another (see Figure 12). If necessary,
repeat Steps 1–2 until they are all aligned.
Figure 11. Example of finger 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 or 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.

Adjusting Setback
Setback is the required distance between the
bending blocks and the clamping fingers to properly make the bend (see Figure 13). 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.

Adjusting Clamping
Pressure
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.

When the clamping pressure is correctly adjusted,
the foot pedal lock plate (see Figure 16) will
spring forward and secure the foot pedal down
when it is fully depressed.
Foot Pedal
Lock Plate
Foot
Pedal
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.
Adjusting Work Stop
The work stop mechanism allows the operator to
produce repetitive bends at the same angle.
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.
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.
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, 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.

SECTION 5: MAINTENANCE
Schedule
For optimum performance from this machine, this
maintenance schedule must be strictly followed.
Ongoing
To maintain a low risk of injury and proper machine
operation, if you ever observe any of the items
below, stop operating the machine immediately
and fix the problem before continuing operations:
• Loose mounting bolts.
• Worn or damaged clamping fingers or bend-
ing blocks.
Any other unsafe condition.
•
Daily
• Lubricate clamping leaf slide shafts.
• Lubricate bending leaf pivot bushings.
Weekly Maintenance
• Lubricate bending leaf cam.
• Lubricate setback shafts.

The slide shaft ball oilers (see Figure 25) provide
lubrication to the sliding surfaces between the
shafts and the frame.

Sliding Surface
Cleaning &
Protecting
Use a brush to clear away any metal debris and
dust from the clamping fingers, clamping base,
and bending blocks.
Use a shop rag to carefully apply a thin coat of
quality metal protectant (see Page 18 for offerings
from Grizzly) to all exposed unpainted surfaces to
prevent corrosion.
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.

Bending Leaf Cam
Grease .................. T26419 or NLGI#2 Equivalent
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 equally to move the bending leaf
back and forth along the shafts to distribute the
lubricant.
Lubrication Points
Figure 28. Example of setback shaft lubrication
locations.
Use mineral spirits and a shop rag to clean each
side of the cam (see Figure 27), then apply a
thin coat of grease to each side. Raise and lower
the bending leaf several times to distribute the
lubricant.
