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
bench or floor, as appropriate. Make sure wheels
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.

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 manufac-
use and make sure you work in a well-ventilated
area to minimize exposure to toxic fumes.
Before cleaning, gather the following:
• Disposable rags

Site Considerations
Weight Load
for the weight
of your machine. Make sure that the surface upon
which the machine is placed will bear the weight
of the machine, additional equipment that may be
installed on the machine, and the heaviest workpiece that will be used. Additionally, consider the
weight of the operator and any dynamic loading
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.
Lighting around the machine must be adequate
enough that operations can be performed safely.
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.
Refer to the Machine Data Sheet

Lifting & Placing
HEAVY LIFT!
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.
The Model G0973 requires the use of lifting equipment such as a forklift, engine hoist, or boom
crane. DO NOT attempt to lift or move machine
without necessary assistance from other people.
Each piece of lifting equipment must be rated for
at least 1520 lbs. to support dynamic loads that
may be applied while lifting.

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.
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.

Selecting
Lower Wheels
Choose a lower wheel that will produce the contour you desire (see Figure 14).
Flat lower wheels (see Figure 14, A) are good for
adding gentle curves to large metal panels; these
wheels have large flat surfaces and square ends.
Domed lower wheels (see Figure 14, B) create
tighter curves; flat areas at the center range from
1
⁄8" to 11⁄4" wide. The wider the flat area, the wider
the track produced on the workpiece.

The quick-release hub can be engaged or disengaged to help release a workpiece, or increase
pressure during operations. Rotating the hub
raises/lowers the lower wheel approximately
terclockwise to tilt lower wheel bracket (see
Figure 20).

Tracking Tips
• Stretching metal into a curve should be
a gradual process. Always start with just
enough wheel pressure to prevent the
workpiece from skipping or slipping through
the wheels. 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.
Frame
• Start with the lower wheel that has the greatest radius (least amount of curve), then
decrease the wheel 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 wheels (see Figure 23). As the 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 23. Example of frame around workpiece
and basic back-and-forth tracking pattern.
• Overlap each pass with the previous one in
a smooth, back-and-forth movement through
the wheels, as shown in Figure 23. There
are many patterns of tracking that will produce different results. Refer to Page 21
for additional tracking patterns. Choosing the
correct pattern for your operation is a matter
of research and experience.
• Try using the lightest wheel pressure possible
to shape the workpiece. Too much pressure
may crease or damage the metal. Light pressure is best for smoothing; higher pressure is
best for rough shaping.
• Take your time. Start rolling slowly and
increase your speed. Many passes through
the wheels with gradual increases in pressure and lower wheel radii will produce good
results and reduce the risk of damaging the
workpiece surface.

Tracking Patterns
As metal passes between the upper and lower
wheels, 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 24) so the metal bends correctly.

Zigzag Pattern
This patterns 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 wheels at point A,

and start rolling it along left edge, as shown
in Figure 25.

Staggered Stop Pattern
With this pattern, the track alternates between
three different sets of lines, helping reduce ridges
that may form at the stopping point of tracks. This
technique is useful on larger workpieces.
Note: It may help to draw lines on the workpiece
with a non-permanent marker so you can see the
outside, middle, and inside lines more clearly.
Clean the wheels and workpiece when finished.
To use staggered stop pattern:
From starting point, roll workpiece from out-
1.
side line on one side to outside line on
opposite side (see Figure 32).
Roll workpiece from middle line on one side

to middle line on opposite side, as shown in

Crisscrossing Tracks
Crisscrossing tracks can help produce smoother
curves in your workpiece when using the zigzag
or staggered stop pattern.
After running tracks along one length of the
workpiece (see Figure 37, A), turn the metal sheet
90° and run tracks along the opposite length (see
Figure 37, B) so the workpiece is equally covered
by both sets of tracks (see Figure 37, C).

maintenance, or service.
Schedule
For optimum performance from this machine, this
maintenance schedule must be strictly followed.
Ongoing
To minimize your risk of injury and maintain proper
machine operation, stop using the machine immediately if you ever observe any of the items below,
and fix the problem before continuing operations:
• Damaged or dirty wheels.
• Damaged or cracked frame.
• Hardware/fasteners for security.
• Any other unsafe condition.
Daily Maintenance
• Clean and protect wheels.
Cleaning the Model G0973 is relatively easy.
Periodically wipe down the machine to remove
dust and debris—this ensures rust-promoting
material does not remain on bare metal surfaces.
Since all bearings on the Model G0973 are sealed
and permanently lubricated, simply leave them
alone until they need to be replaced. DO NOT
lubricate them.
Protect the unpainted metal surfaces with regular
applications of products like SLIPIT®, as shown in
Figure 45 below.

Lubrication
When lubricating this machine, first clean the
components before lubricating them. This step is
critical because grime and dust build up on lubricated components, which makes them hard to
move. Simply adding more lubricant will not result
in smooth moving parts.
