Safety Instructions for Machinery
SECTION 1: SAFETY
-6-
Model T27621 (Mfd. Since 2/16)
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 mate-
rial. Always wear a NIOSH-approved respirator to
reduce your risk.
HEARING PROTECTION. Always wear hear-
ing 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 modifica-
tions—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 dur-
ing 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 rec-
ommended accessories. Using improper acces-
sories 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 disconnect-
ing cord-connected machines from power, grab
and pull the plugNOT 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.

Model T27621 (Mfd. Since 2/16)
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 preven-
tative, but the following steps work well in a wide
variety of situations. Always follow the manufac-
turer’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)
Basic steps for removing rust preventative:
1.
Put on safety glasses.
2.
Coat the rust preventative with a liberal
amount of cleaner/degreaser, then let it soak
for 5–10 minutes.
3.
Wipe off the surfaces. If your cleaner/degreas-
er is effective, the rust preventative will wipe
off easily. If you have a plastic paint scraper,
scrape off as much as you can first, then wipe
off the rest with the rag.
4.
Repeat Steps 2–3 as necessary until clean,
then coat all unpainted surfaces with a quality
metal protectant to prevent rust.
Gasoline and petroleum
products have low flash
points and can explode
or cause fire if used to
clean machinery. Avoid
using these products
to clean machinery.
Many cleaning solvents
are toxic if inhaled. Only
work in a well-ventilated
area.
NOTICE
Avoid chlorine-based solvents, such as
acetone or brake parts cleaner, that may
damage painted surfaces.
T23692—Orange Power Degreaser
A great product for removing the waxy ship-
ping grease from the non-painted parts of the
machine during clean up.

Weight Load
Refer to the Machine Data Sheet
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 work-
piece that will be used. Additionally, consider the
weight of the operator and any dynamic loading
that may occur when operating the machine.
Physical Environment
The physical environment where the machine
is operated is important for safe operation and
longevity of components. For best results, oper-
ate this machine in a dry environment that is
free from excessive moisture, hazardous chemi-
cals, 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 2095% (non-condensing); or
the environment is subject to vibration, shocks,
or bumps.
Children or untrained people
may be seriously injured by
this machine. Only install in an
access restricted location.
Lighting
Lighting around the machine must be adequate
enough that operations can be performed safely.
Shadows, glare, or strobe effects that may distract
or impede the operator must be eliminated.
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 main-
tenance and service described in this manual.
See below for required space allocation.

Anchoring to Floor
Lag shield anchors with lag screws (see below)
are a popular way to anchor machinery to a con-
crete 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.

SECTION 3: OPERATIONS
Operation Overview
The purpose of this overview is to provide the nov-
ice machine operator with a basic understanding
of how the machine is used during operation, so
the
machine controls/components
discussed later
in this manual
are easier to understand.
Due to the generic nature of this overview, it is
not intended to be an instructional guide. To learn
more about specific operations, read this entire
manual and
seek additional training from expe-
rienced
machine operators, and do additional
research outside of this manual by reading "how-
to" books, trade magazines, or websites.
To complete a typical operation, the operator
does the following:
1. Puts on safety glasses, leather boots, and
leather gloves.
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
handwheel.
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.
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.
To reduce your risk of
serious injury, read this
entire manual BEFORE
using machine.
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 proj-

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.
Start with the lower wheel that has the great-
est 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.
Frame
...and so on
Figure 11. 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 11. There
are many patterns of tracking that will pro-
duce 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.
Take your time. Start rolling slowly and
increase your speed. Many passes through
the wheels with gradual increases in pres-
sure and lower wheel radii will produce good
results and reduce the risk of damaging the
workpiece surface.

Replacing Wheels
To replace upper wheel:
1. Raise lower wheel until both wheels touch.
This ensures upper wheel is supported.
2. Remove two cap screws and locking plate
shown in Figure 12.
3. Turn upper wheel handle (see Figure 12)
clockwise to lock upper wheel bracket against
frame so upper wheel will not move.
Note: Use one hand to steady bracket to pre-
vent it from rotating while turning handle.
Tools Needed Qty
Hex Wrench 4mm .............................................. 1
Brass Punch ...................................................... 1
Hammer ............................................................. 1
A flat upper wheel is pre-installed on the English
wheel. It can be replaced with either of the two
grooved upper wheels. Also, any of the nine lower
wheels can be replaced.
CRUSHING HAZARD! Hold an upper wheel
securely when installing or removing it
or it may fall on your foot! Wear steel toe
footwear to protect your feet.
4. While an assistant holds upper wheel, remove
upper wheel axle and spacers, as shown in
Figure 13.
Figure 13. Using punch and hammer to remove
upper wheel axle.
5. Carefully remove upper wheel, install includ-
ed mounting shaft in wheel, and place wheel
on upper wheel rack.
6. Place new upper wheel between upper wheel
bracket arms (see Figure 13).
Note: Adjust lower wheel height if you have
difficulty replacing upper wheel.
7. Align wheel bearing hole and spacers with
upper wheel bracket mounting holes, then
drive axle through components (in reverse of
Figure 13). Make sure detent on right side
of axle faces up (see Figure 14) so it can be
secured properly.
8. Re-install locking plate and cap screws
removed in Step 2.

3. Lift lower wheel bracket until screw shown in
Figure 18 reaches top of groove in adjust-
ment shaft.
8. Re-install lower wheel, engage quick-release
lever, and raise lower wheel to operating
position.
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.
Tools Needed:
