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.

Page 9
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 Metal Shears
and ensure guards are properly installed. DO NOT
Serious cuts, amputation, or death can occur from contact with the shear blades during
operation, adjustment, or maintenance. To reduce this risk, anyone using this machine MUST
completely heed the hazards and warnings below.
FINGER AMPUTATION. The shear blades or hold-
down can easily pinch, crush, or amputate fingers or
other body parts. Always keep hands, fingers, and
other body parts away from blades and hold-down
(point-of-operation) during shearing operations.
CAPACITY. Exceeding cutting capacity of shear
may result in breakage or machine damage that
ejects dangerous metal debris at operator or
bystanders. Only use sheet metal within the rated
capacity of this shear (refer to the Machine Data
Sheet).
BLADE CONDITION. Sharp, undamaged, and
properly adjusted blades will reduce risk of injury
from breakage or sharp burrs left on workpiece.
Always keep blades properly adjusted and sharp.
SHEAR BLADE ADJUSTMENT. When adjusting or replacing shear blades, always wear heavy
leather gloves to protect hands and wear safety
glasses to protect eyes.
PROPER WORKPIECE MATERIAL. Shear is only
intended for cutting ferrous and non-ferrous mild
sheet metal or flat stock. Do not attempt to cut
round metal stock, glass, wood, drywall, backer
board, plywood, or other material not intended for
this machine. Cutting incorrect materials can produce unexpected results, which increases risk of
injury, and may result in damage to machine.
SHARP METAL EDGES. The sharp edges of
sheet metal can easily cut fingers, hands, and
other body parts. Always wear heavy leather
gloves when handling sheet metal. Always chamfer and deburr sharp workpiece edges.
OPERATOR POSITION. Avoid awkward body
and hand positions where a sudden slip could
cause your hand or body to enter point-of-operation or make accidental contact with shear blades.
MAINTENANCE/SERVICE. Always wait for all
moving parts to come to a complete stop before
performing any adjustments, service, or maintenance. Do not contact foot pedal while performing
these adjustments.
GUARDS. Keep all guards in place, properly
positioned, and in working order. Never operate
shear with blade guard removed. If blade guard
is removed or not properly positioned, fingers
may accidentally be cut or amputated by shear
blades. Always position guard just high enough to
allow workpiece to enter, but not high enough for
fingers.
CHECK MACHINE. Before using machine, carefully check components for wear that could affect
operation. Check blade alignment and gib play,
operate machine until all defects are corrected.
WORK AREA. Provide sufficient clearance around
machine to permit safe use by regular operators and performance of maintenance procedures.
Keep work area clear of materials or substances
that may create a slip, trip, or fall hazard.
-8-
STRAY SHEET METAL PIECES. Sheet metal
cut-off pieces left on the floor can easily slide
under foot and cause falling injuries. Always
remove cut-off sheet metal pieces from the floor
after operation. Keep work area clean.

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)

Physical Environment
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.
Shadows, glare, or strobe effects that may distract
Space Allocation
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.

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.
Lifting & Placing
HEAVY LIF T!
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.
Use a forklift (or other type of lifting equipment)
with lifting straps to move the machine to your
desired location. All lifting equipment should be
rated for at least 1500 pounds.

Cutting Tips
• Never attempt to cut any workpiece narrower
than 1⁄2". The workpiece must be long enough
to be engaged by the hold-down/blade guard.
• Keep the upper blade properly adjusted to
the lower blade (refer to Adjusting Blade
Gap on Page 26 for detailed instructions).
This will help ensure good cutting results and
avoid blade damage.
• Before each operation, clean cut-offs or
debris away from the shear.
Adjusting Rear
Work Stop
The rear work stop is used for making repetitive
cuts of the same length. The micro-adjustment
assemblies allow for precise positioning of the
work stop.
To adjust rear work stop:
Loosen (2) rear work stop lock knobs and (2)
1.
micro-adjustment lock knobs (see Figure 19).
• Use the foot pedal to engage the hold-down/
blade guard with the workpiece, then pause
to check the workpiece position. If workpiece
position is correct, continue lowering the foot
pedal to complete the cut.
• The shearing action of the blades works
similarly to a pair of scissors (see illustration in Figure 18). Use even pressure on the
foot pedal throughout entire cut to produce a
straight, even cut.

Sharpening/
Replacing Blade
The upper blade of the Model T32957 has two
cutting edges so that if one cutting edge becomes
dull, you can reverse the blade and use the fresh,
sharp cutting edge.
If both of the upper blade cutting edges are dull,
or the cutting edge of the lower blade is dull,
sharpen the blade(s) on a surface grinder and
make sure the blade is flat along the entire length.
Re-sharpen each blade edge as needed until it is
too thin to safely install (as described in the steps
below), then replace the blade. We recommend
you keep an extra set of blades on hand to avoid
any downtime.

Adjusting Blade Gap
The gap between the upper and lower blades (as
they pass each other) must remain even along
the length of the blades to produce clean cuts.
Initially, this adjustment has been made at the
factory. However, over time and with normal wear,
you may need to adjust the blade gap.
Loosen (2) table bolts, (2) table adjustment
2.
bolts, and (2) jam nuts on side of shear that
needs adjustment (see Figure 36).
Table Adjustment
Bolt (1 of 2)
If the blade gap is too wide, the workpiece will
not cut correctly and show signs of bending, ripping, or tearing. If the blade gap is too narrow,
the upper blade will bind when lowering past the
lower blade and the cutting edges may become
damaged.
