SECTION 1: SAFETY
For Your Own Safety, Read Instruction
Manual Before Operating This Machine
The purpose of safety symbols is to attract your attention to possible hazardous conditions.
This manual uses a series of symbols and signal words intended to convey the level of importance of the safety messages. The progression of symbols is described below. Remember that
safety messages by themselves do not eliminate danger and are not a substitute for proper
accident prevention measures. Always use common sense and good judgment.
Indicates an imminently hazardous situation which, if not avoided,
WILL result in death or serious injury.
Indicates a potentially hazardous situation which, if not avoided,
COULD result in death or serious injury.
Indicates a potentially hazardous situation which, if not avoided,
MAY result in minor or moderate injury. It may also be used to alert
against unsafe practices.
This symbol is used to alert the user to useful information about
NOTICE
proper operation of the machine.
Safety Instructions for Machinery
OWNER’S MANUAL. Read and understand this
owner’s manual BEFORE using machine.
TRAINED OPERATORS ONLY. Untrained operators have a higher risk of being hurt or killed.
Only allow trained/supervised people to use this
machine. When machine is not being used, disconnect power, remove switch keys, or lock-out
machine to prevent unauthorized use—especially
around children. Make your workshop kid proof!
DANGEROUS ENVIRONMENTS. Do not use
machinery in areas that are wet, cluttered, or have
poor lighting. Operating machinery in these areas
greatly increases the risk of accidents and injury.
MENTAL ALERTNESS REQUIRED. Full mental
alertness is required for safe operation of machinery. Never operate under the influence of drugs or
alcohol, when tired, or when distracted.
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.
nect 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.
Always discon-

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.
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
ensure all moving parts completely stop before
walking away. Never leave machine running
while unattended.
MAINTAIN WITH CARE. Follow all maintenance
instructions and lubrication schedules to keep
machine in good working condition. A machine
that is improperly maintained could malfunction,
leading to serious personal injury or death.
DAMAGED PARTS. Regularly inspect machine
for damaged, loose, or mis-adjusted parts—or
any condition that could affect safe operation.
Immediately repair/replace BEFORE operating
machine. For your own safety, DO NOT operate
machine with damaged parts!
MAINTAIN POWER CORDS. When disconnecting cord-connected machines from power, grab
and pull the plug—NOT the cord. Pulling the cord
may damage the wires inside. Do not handle
cord/plug with wet hands. Avoid cord damage by
keeping it away from heated surfaces, high traffic
areas, harsh chemicals, and wet/damp locations.
EXPERIENCING DIFFICULTIES. If at any time
you experience difficulties performing the intended operation, stop using the machine! Contact our
Technical Support at (570) 546-9663.

Additional Safety for Pan and Box Brakes
1. OVERLOADING PAN AND BOX BRAKE.
Overloading this tool can cause injury from
flying parts. Do not exceed the capacities
specified on Page 8.
2. USAGE. Do not use this pan and box brake
as a press or a lever-operated crushing
tool. Never use this machine without fully
understanding its limitations.
3. METAL EDGES. Always chamfer and deburr sharp sheet metal edges before bending in the pan and box brake. Sharp edges
on sheet metal can cut your fingers to the
bone.
4. PINCHING. Always keep hands away from
the clamping leaf. This area presents a
severe pinching hazard.
5. GLOVES AND GLASSES. Always wear
leather gloves and approved safety glasses
when using this tool.
6. EXPERIENCING DIFFICULTIES. If at any
time you are experiencing difficulties performing the intended operation, STOP using
the tool and contact our Technical Support at
(570) 546-9663, or ask a qualified expert how
the operation should be performed.
7. TOOLS IN POOR CONDITION. Inspect the
pan and box brake for any cracked linkage,
levers, or loose fasteners. Correct any problems before use.
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.
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.

1. Lift the hold down handle to open the hold
down assembly all the way.
2. Insert the sheet metal workpiece between
the hold down assembly and the body.
3. Align the fingers of the hold down assembly
to the bend mark on the workpiece.
4. Move the hold down handle to hold the workpiece with the hold down assembly. Note—
Do not force the hold down handle. If the
handle is hard to put in the locked position,
the brake may need to be adjusted for the
workpiece thickness. The clamping pressure
of the hold down assembly needs to be just
tight enough to hold the workpiece from moving when bending.
5. Lift up on the apron handles (using both
hands) until the workpiece has reached the
desired angle.
6. Lift the hold down handle to open the hold
down assembly then remove the bent workpiece. Note—If a pan or box bend is desired,
choose a die or a selection of dies that are as
close as possible to the length of pan or box
side.
