Page 8
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 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
floor. Make sure wheels are properly installed on
support brackets or storage racks. Wear steeltoed 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.

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

operating machine or handling sheet steel.
2. Deburrs sharp edges (see Accessories on
Page 24 for optional deburring tool).
3.Cleans workpiece and wheels thoroughly and
removes all abrasive particles.
4. Turns upper wheel handle clockwise to raise
upper wheel bracket against frame.
5. Installs lower wheel with greatest radius
(least amount of curve).
6. Verifies distance between bottom of upper
wheel and top of lower wheel are about an
inch apart, and adjusts distance with height

7. Engages quick-release lever to raise lower
wheel to operating position.
8. Marks approximate 1" frame around
workpiece (refer to Page 15), then inserts
workpiece between wheels.
9. Rotates lower adjustment handwheel until
there is just enough pressure to prevent
workpiece from skipping or slipping.
If you are not experienced with this type
of machine, WE STRONGLY RECOMMEND
that you seek additional training outside of
this manual. Read books/magazines or get
formal training before beginning any projects. Regardless of the content in this section, Grizzly Industrial will not be held liable
for accidents caused by lack of training.

10. Moves workpiece back and forth through
wheels using a tracking pattern (refer to Page
20), rolling it up to an edge, rotating it slightly,
then pulling it back.
11. When workpiece no longer stretches, rotates
adjustment handwheel clockwise to slightly
increase pressure.
12. When maximum wheel pressure is reached
and workpiece no longer moves through
wheels, disengages quick-release lever, and
changes lower wheel to next lower radius.
13. Repeat Steps 3–12 until curve is attained.
Model T27621 (Mfd. Since 2/16)
Page 17
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.
• Overlap each pass with the previous one in
a smooth, back-and-forth movement through
the wheels, as shown in Figure 11. There
are many patterns of tracking that will produce different results. Refer to Page 20 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
will crease or ruin the metal. Light pressure
is best for smoothing; higher pressure is best
for rough shaping.
• 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 11). 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 accomodate expansion of the metal and
removal of excess material, if needed.
• 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.

Adjusting Quick-
Release Lever
The quick-release lever is adjusted at the factory.
However, due to variables involved with shipping,
it may need to be adjusted.
If the set screws on the steel cams do not engage
the detents on the quick-release lever, the lever
shaft will slip in the cams, causing it to malfunction.
6. Turn upper wheel handle counterclockwise
several turns to lower upper wheel bracket.
1. Examine detents (see Figure 20) on both
sides of quick-release lever.

Selecting Lower
Wheels
Roll a workpiece between a grooved lower wheel
(see Figure 21, C) and a ridged upper wheel to
emboss metal, as shown in Figure 22.
Choose a lower wheel (see Figure 21) that will
produce the contour you desire.
B
A
Flat
D
C
Figure 21. Lower wheels.
Flat lower wheels (see Figure 21, 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 21, B) create
tighter curves; flat areas at the center range from
3
⁄4" to 1⁄8" wide. The wider the flat area, the wider
the track produced on the workpiece.

Tracking Patterns
B
B
B
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:
1. Insert workpiece between wheels at point A,
and start rolling it along left edge, as shown
in Figure 25.
CAUTION: Move your hands out of wheel
pathway so you do not pinch them!

Note: Avoid rolling directly over center of
workpiece, as too many passes could overstretch
metal.

Page 24
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:
1. From starting point, roll workpiece from outside line on one side to outside line on
opposite side (see Figure 32).
3. Roll workpiece from inside line on one side to
inside line on opposite side (see Figure 34).
Figure 34. Example of rolling inside to inside
line.
4. Repeat Steps 1–3, as you move across
workpiece, randomly alternating between
outside, middle, and inside lines, as shown in
Figures 35–36.

line.
2. Roll workpiece from middle line on one side to
middle line on opposite side (see Figure 33).

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, 1), turn the metal sheet
90° and run tracks along the opposite length (see
Figure 37, 2) so the workpiece is equally covered
by both sets of tracks (see Figure 37, 3).
