The EASTWOOD 48” PAN AND BOX BRAKE is a precision engineered metal working tool designed to produce accurate, variable length bends in angles up to
135° in mild, 18 gauge sheet steel and 16 gauge aluminum in widths up to 48”. Create complex shapes such as floor reinforcement channels and ribs, sections
of corrugated pickup bed floors; truck bedside panels, inner fender structures and much more, all with one convenient bench-mounted tool.
TOOLS REQUIRED (not included)
• 8mm Hex Key
• 6mm Hex Key
• 24mm Wrench
• Medium/Large Phillips Screw driver
• Feeler Gauge Set
• Angle Gauge or Protractor
DANGER indicates a hazardous situation which, if not avoided, will result in death or serious injury.
WARNING indicates a hazardous situation which, if not avoided, could result in death or serious injury.
CAUTION used with the safety alert symbol, indicates a hazardous situation which, if not avoided, could result in minor or moderate injury.
NOTICE is used to address practices not related to personal injury.
READ INSTRUCTIONS
• Thoroughly read and understand this manual before using this machine.
• Save for future reference.
PINCH AND CRUSH HAZARD!
• The Eastwood Pan and Box Brake consists of heavy metal components which can present a hand/finger pinch hazard and cause
potentially serious injuries if dropped. Avoid pinching hands while handling. The use of safety shoes is strongly recommended.
Keep fingers and hands away from moving parts when operating.
CUT HAZARD!
• Handling sharp metal can cause serious cuts. Wear thick, well-fitting work gloves to prevent cuts from handling sharp metal.
EYE INJURY HAZARD!
• Metal particles can be ejected from the metal surface when bending. Sheet metal edges and corners are sharp and can injure eyes.
Always wear ANSI approved eye protection when operating this tool.
SAFETY INFORMATION
The following explanations are displayed in this manual, on the labeling, and on all other information provided with this product:

• Before beginning ANY work with this tool, it is absolutely necessary that it be securely bolted to a sturdy workbench anchored to
the floor or wall.
• Strenuous physical force may need to be applied to the Pan and Box Brake during use. Failure to ensure proper footing can quickly
result in a fall which could inflict serious personal injury or property damage. Always work in a clean, uncluttered environment.
• Be sure there is sufficient working room around the tool to allow for safe handling of various sizes of metal.
• The Eastwood Pan and Box Brake was specifically designed to be operated by one person only. Never have one person operate the
Bending Bar while another handles the workpiece or serious injury could occur.
• Excessive resistance while operating could indicate a defect with the workpiece material or broken or damaged Pan and Box Brake
components. To avoid injury, stop work immediately and inspect workpiece material for nicks, dents, welds, excessive scale or
remaining coatings. Clean or repair as necessary or discard and begin with a new piece. Also inspect Pan and Box Brake components
for looseness or damage.
SET-UP
• The Eastwood Pan & Box Brake must be securely mounted on a heavy, solid workbench, stand, floor etc, capable of holding the static weight of
the unit plus the stresses from operation. The use of 3/8” through bolts & nuts or longer lag screws with substantial washers and attachment to
a structural member is absolutely necessary.
• Place the Pan & Box Brake over the chosen location then mark mounting hole locations by tracing holes in the feet.

OPERATION
• Select the Finger width or combination of Fingers required to
bend the desired width of Sheetmetal.
• Add or delete Fingers as required by loosening the 8mm
Socket Head Cap Screws to remove Fingers (FIG 1).
• To add Fingers to achieve desired width, set in place and
secure with a Socket Head Cap Screw and securely tighten
with 8mm Hex Key (not included).
NOTE: Several adjustments must be made prior to bending metal.
• Adjust Finger Alignment – The Fingers need to be aligned
squarely with one another, the lower machined Platen Surface
and the upper cam driven Pressure Bar.
- To adjust, loosen the socket head cap screws retaining the
fingers with an 8mm Hex Key (not included).
- Move Fingers so the top edges are square to the Pressure
Bar and the sides are square to adjoining Fingers (FIG 1).
• Adjust Pivot-Cams for Bend Radius – The Pivot-Cams adjust
the Knife-Edge of the Fingers in or out to provide the correct
bend radius for the thickness and composition of the material
being bent.
- To adjust, use a 6mm Hex Key (not included) to loosen the
Set-Screws at the upper rear of the Frame (FIG 2).
- Insert a Medium/Large Philips screw driver into one of the
several holes around the circumference of the Cam and
rotate it forward or back as required to move the Knife-
edge of the Fingers toward or away from the edge of the
machined Platen surface (FIG 2).
FIG. 2
Do not allow the Knife-edge of the fingers to
protrude beyond the edge of the machined Platen
or permanent damage to the Fingers and Bending
Bar will occur.

A word about Bend Radius: Every gauge and type of Sheetmetal
has a minimum Bend Radius. If an attempt is made to bend that
metal sharper than the allowable Bend Radius, it will fatigue and
crack. It is best to consult an online table or a Machinery’s Handbook
for the proper Bend Radius. A good “rule-of-thumb” to employ is
never set the distance of the Knife-edge of the Fingers any less than
1-1/2 X the thickness of the metal being bent.
• Adjust Pressure Bar for Metal Thickness – The Pressure Bar
needs to raise or lower the attached Fingers as needed to
accommodate the thickness of the selected sheetmetal.
- To adjust (for thicker material), loosen the Lower Nut on
the Adjustment Arm with a 24mm wrench (not Included)
(FIG 3).
- Using a 24mm wrench (not Included) rotate the Upper
Adjustment Nut Counter Clockwise to raise the Pressure
Bar (FIG 4).
- Tighten the Lower Nut to lock in your adjustment.
- To adjust (for thinner material), loosen the Upper Nut on
the Adjustment Arm with a 24mm wrench (not Included)
(FIG 4).
- Using a 24mm wrench (not Included) rotate the Lower
Adjustment Nut Clockwise to raise the Pressure Bar
(FIG 3).
- Tighten the Upper Nut to lock in your adjustment.
- When done, use a feeler gauge at several locations
between the knife-edge of the Fingers and the Platen
Surface to verify metal gauge adjustments (FIG 5).
NOTE: The proper gap will clamp the Sheetmetal just tight enough
to prevent movement when bending yet not so tight as to generate
excess effort in the Clamping Handle.

• Adjust tension to the Cam Handles so that they stay in a
desired position when open or move more freely. To do so:
- Loosen the Outer Jam Nut with a 24mm wrench
(not Included) (FIG 6).
- Then tighten the Inner Nut with a 24mm wrench
(not Included) to your desired tension (FIG 7).
- Tighten the Outer Jam Nut with a 24mm wrench
(not Included) to secure the adjustment.
- Repeat this step on the other Cam Handle if desired.
With all the Fingers in place, bends up to 135° can be made in
18 gauge mild steel panels up to 48” wide. To do so;
• Measure and mark the desired bend line on your sheetmetal
panel.
• Raise the Fingers by rotating the Cam Handles Upward.
• Slide panel under the Fingers lining up your pre-marked bend
line with the lower, beveled edge of the Fingers.
NOTE: the edge of the Fingers are set back slightly from the edge of
the machined Platen Surface of the main body to allow for a suffi-
cient bend radius of the metal and the most accurate bends (FIG 8).
• Rotate the Cam Handle downward to clamp the Fingers
against the Sheetmetal panel.
• Grasping both handles of the moveable Bending Bar, lift
upward, bending your panel until the desired bend angle
is achieved (FIG 8).
NOTE: The use of an angle gauge or protractor (not included)
is recommended.
• Depending on the particular alloy being bent, it may be
necessary to rotate the Bending Bar slightly beyond the
desired angle to allow for “springback”. Some trial and error
is suggested on scrap material before making final bends.

MAINTENANCE
• Provide several drops of oil to pivot points periodically to prevent binding.
• Keep all areas of the tool clean, particularly those surfaces that contact sheetmetal work pieces. Dirt and metal chips can cause uneven clamping
and inaccurate bends.
• Store in a clean & dry environment when not in use. Coat all machined surfaces with a light film of oil or suitable protectant to prevent
rust formation.
