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-

Model T28964 (Mfd. Since 12/18)

-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.

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 [phone].

Additional Safety for English Wheels

Fingers can be broken or severely pinched if caught between wheels 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.

PINCHING/CRUSHING HAZARD. The roll-

ing momentum of wheels can pull your fingers
between them, resulting in pinching or crushing
injuries. Always keep your hands away from
wheel path when moving workpiece through
wheels.

METAL EDGES. The sharp edges of sheet metal
can quickly cut your fingers or hands. Always
wear heavy leather gloves when handling sheet
metal. Always chamfer and deburr sharp metal
edges before inserting them into English Wheel.

TOOL USAGE. This English Wheel was designed
only to form curves in sheet metal material such
as steel, aluminum, and copper. Do not attempt to
process any other material (e.g., glass, ceramic,
plastic, etc.) that could result in material or tool
breakage. Do not modify this tool in any way and
do not exceed the capacity listed in the Machine

Data Sheet.

CRUSHING HAZARD. If wheels or frame should

unexpectedly fall, crushing injuries could result.
Always make sure frame is correctly mounted
to workbench. Make sure anvils are properly
installed on support brackets or storage racks.
Wear steel-toed boots.

BODY POSITION. Losing your balance while
tracking could result in impact injuries or cuts from
sheet metal. Make sure your body and footing are
balanced and in a good position to support your
movement and momentum while tracking.

TOOL INSPECTION. Using English Wheel with
excessively worn or damaged parts could cause
tool to fail and present injury hazards, as well as
yield poor results. Always inspect each part of
English Wheel before beginning operations.

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 T28964 (Mfd. Since 12/18)

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.

Tracking Tips

• Stretching metal into a curve should be
a gradual process. Always start with just
enough pressure to prevent the workpiece
from skipping or slipping through the wheel
and anvil. After the initial curve has formed,
increase the pressure slightly and continue
stretching the metal. Repeat this process
until the desired curve is attained. Using too
much pressure will damage the workpiece
surface and produce poor results.

• Overlap each pass with the previous one in
a smooth, back-and-forth movement through
the wheel and anvil, as shown in
There are many patterns of tracking that will
produce different results. Refer to
for additional tracking patterns. Choosing the
correct pattern for your operation is a matter
of research and experience.

• Try using the lightest pressure possible to
shape the workpiece. Too much pressure
will crease or ruin the metal. Light pressure
is best for smoothing; higher pressure is best
for rough shaping.

Figure 11.

Page 17

• Start with the anvil that has the greatest radi­us (least amount of curve), then decrease the
anvil radius a step at a time until the desired
curve is reached.

• Mark the workpiece with a non-permanent
marker to make it easier to follow tracking
patterns or contour the metal.

• Practice with a scrap piece that is the same
material and thickness as the final workpiece.

• Leave a frame around the workpiece of
approximately 1" that does not go through
the wheel and anvil (see
center of the workpiece stretches and the
frame does not, the metal is forced to bend
into a curve. Some workpieces may need a
larger frame to accommodate expansion of
the metal and removal of excess material, if
needed.

Figure 11). As the

• Take your time. Start rolling slowly and
increase your speed. Many passes through
the wheel and anvil with gradual increases
in pressure and anvil radii will produce good
results and reduce the risk of damaging the
workpiece surface.

tracking

As metal passes between the wheel and anvil,
a "track" or shiny line is pressed into the metal.
Various tracking patterns can be used to shape
workpieces depending upon their shape or size.

Note: Most of the figures in this section are shown
without a frame for clarity, but we recommend
leaving about a 1" border around the workpiece
(see Figure 18) so the metal bends correctly.

Zigzag Pattern

This pattern resembles the closely-spaced tracks
of a lawn mower cutting a lawn. It can be used for
a variety of workpiece shapes.

To use zigzag tracking pattern:

Insert workpiece between wheel and anvil at

point A, and start rolling it along left edge, as
shown in Figure 19.

CAUTION: Move your hands out of pathway

so you do not pinch them!
