Models T26472Z/G4011Z/T26751Z are designed
to roll, bend, and cut sheet metal. Though each
m a c h i n e c a n c o m p l e t e e a c h o f t h e s e t a s k s ,
the capacities generally increase in relation to the
size of the machine. Additionally, as the machines
increase in size, so do the number of fingers,
creating more available options for box and pan
bending. Refer to the Machine Data Sheet on
Page 4 for individual model specifications.
The slip rollers straighten or form cylinders,
cones, and arcs in sheet metal. The brake creates
bends up to 90° and folds sheet metal into boxes,
pans, or trays. The shear blade moves down past
the fixed table blade to shear the workpiece.

Safety Instructions for Machinery
SECTION 1: SAFETY

-6- T26472Z/G4011Z/T26751Z (Mfd. Since 02/14)
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 avoid
accidental slips, which could cause loss of work-
piece control.
HAZARDOUS DUST. Dust created while using
machinery may cause cancer, birth defects, or
long-term respiratory damage. Be aware of dust
hazards associated with each workpiece material,
and 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.
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

Additional Safety for 3-in-1
Sheet Metal Machines
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 pre-
cautions are overlooked or ignored, seri-
ous personal injury may occur.
No list of safety guidelines can be com-
plete. 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 equip-
ment, or poor work results.
AMPUTATION/PINCHING HAZARD. This
machine can quickly crush or amputate fingers,
hands, or body parts. Never place fingers, hands,
or body parts between or near the rollers, brake
fingers, clamping bar, or shear blades when oper-
ating.
RATED CAPACITY. Only workpieces that are with-
in the rated gauge capacity can be processed with
this machine (refer to the Machine Data Sheet on
Page 4). DO NOT use any sort of “cheater” bar or
pipe on the hand crank.
SHARP METAL EDGES. Sharp edges on sheet
metal workpieces can easily cause deep cuts
while handling. Wear leather gloves to help protect
your hands, and always chamfer and debur sharp
workpiece edges.
USAGE. To avoid personal injury or property
damage, always use each component of machine
for its intended purposes, and DO NOT modify
machine in any way.
Serious injury or death can occur from getting body parts crushed or amputated by shear blades,
brake fingers, or rollers. Severe cuts can occur from contact with workpiece edges. To minimize
the risk of getting hurt or killed, anyone operating this machine MUST completely heed the
hazards and warnings below.
SECURE MACHINE BEFORE USE. Before using,
fasten machine to a sturdy surface that can with-
stand the dynamic forces involved in cutting and
forming sheet metal. Otherwise, machine may
unexpectedly move or fall, causing serious injury
or property damage.
SHEAR BLADES/BRAKE FINGERS. If not prop-
erly aligned, shear blades or brake fingers can
ruin workpieces and machine parts or result in
unexpected movement of workpieces. ALWAYS
keep these parts properly adjusted and in good
working condition for best results and predictable
performance.
STABLE FOOTING. This machine requires opera-
tor to apply moderate force, especially while using
shear. Without stable footing, operator could slip or
fall, resulting in personal injury. Always stand with
both feet comfortably on a non-slip surface during
operation.

Cleaning Fingers
The brake fingers (see Figure 3) are coated with
rust preventative that should be removed before
beginning operation.
Although the rust preventative was applied only to
the visible surfaces of the fingers, some may have
worked in-between and underneath them. We
recommend that you remove all of the fingers to
thoroughly clean them. In addition to being messy,
the rust preventative effects the precision of finger
adjusting and spacing, which may lead to slight
inaccuracies in finished workpieces.
If you do remove the fingers, make sure you prop-
erly align them as described in the Replacing/
Seating Fingers subsection on Page 28 after
re-installing.
Figure 3. Brake fingers.
Brake
Fingers
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 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.
NOTICE
Avoid chlorine-based solvents, such as
acetone or brake parts cleaner, that may
damage painted surfaces.

Assembly
Models T26472Z, G4011Z, and T26751Z are all
packaged, shipped, and assembled the same
way. The only difference during assembly is the
size of cap screws used to secure the end cap on
each model. Familiarize yourself with the compo-
nents and fasteners shown in Figure 9 to assist
in machine assembly.
To assemble machine:
1. Remove one cap screw from end cap, loosen
other cap screw, and rotate end cap out of
way. Back pre-installed lock knob out so that
it is flush with end cap.
2. Insert crank arm into slot in crank handle hub,
rotate end cap back into place, re-install cap
screw, then tighten both cap screws.
3. Tighten lock knob.
4. Repeat Steps 1–3 to install remaining crank
handle on other side of machine.

SECTION 3: OPERATIONS
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-
ects. Regardless of the content in this sec-
tion, Grizzly Industrial will not be held liable
for accidents caused by lack of training.
Slip Roll Overview
The slip roll is used to flatten or form cylinders,
cones, and arcs in mild sheet metal, as well as
wires and rods. Refer to the Machine Data Sheet
on Page 4 for individual machine specifications
and workpiece capacities.
The work of a slip roll is accomplished by feeding
the workpiece between steel rollers to produce
the desired results. Two of the three rollers can
be adjusted by the operator to accept different
workpiece thicknesses and produce a variety of
different work results. Refer to Figures 12–13 for
identification of slip roll components and controls.

Slip Roll Tips
• Due to the many variables of different sheet
metal types, no single configuration of the
rollers will create the same curve on all mate-
rials. Rolling sheet metal to achieve an exact
radius is a trial-and-error process.
• Best results are usually achieved by perform-
ing multiple passes while gradually reducing
the curve radius with each pass—rather than
trying to make the curve in one pass.
• To avoid pitted workpieces and damage to
roller surfaces, always make sure workpiece
and rollers are free of grit and any foreign
material before every use.
• When creating cylindrical workpieces, always
keep the rear roller parallel with front rollers
by rotating the diameter adjustment knobs
same amount. Otherwise, coned workpieces
will be formed that are difficult to straighten
out.
Flat Rolling
The rollers present a seri-
ous pinching hazard.
Always keep hands/fingers
at least 6" away from rollers
during operation. Failure
to follow this warning may
result in fingers, hair, or
clothing being pulled into
the machine, causing per-
sonal injury.
To flat roll a workpiece:
1. Use diameter adjustment knobs to lower rear
roller until it is level with bottom roller, as illus-
trated in Figure 14.

This slip roll can be used to "flat roll" sheet metal.
This can be done to straighten sheet metal that is
slightly out of form.
Unless otherwise instructed, make all roller adjust-
ments the same on each side to produce sym-
metrical workpieces.
2. Turn both thickness adjustment knobs coun-
terclockwise until you can insert workpiece
between top and bottom rollers.
3. Evenly lower thickness adjustment knobs
until you feel resistance and workpiece is
held firmly between rollers.
4. Remove workpiece and evenly rotate thick-
ness adjustment knobs 1⁄4 turn clockwise to
create additional pressure on workpiece.
5. Re-insert workpiece and use hand crank to
draw workpiece through machine.
Note: Have an assistant support long
workpieces as they leave machine so they do
not bend from sagging as they exit the rollers.
6. Repeat Steps 3–5 until desired results are
produced.
Note: Once a workpiece has been sharply
creased or bent, it cannot be straightened using
this slip roll.

Rolling Curves
This machine can easily create symmetrical
or cone shaped curves. To create symmetrical
curves, make equal adjustments with diameter
adjustment knobs. For cones, rotate one adjust-
ment knob more than the other. Refer to the
Machine Data Sheet on Page 4 for the maximum
thickness or gauge of material your particular
model can handle.
The method of creating a specific radius requires
a trial-and-error process. Due to the many vari-
ations among different types of sheet metal
workpieces, no single configuration of the rollers
will reproduce the same curve in all materials. We
recommend testing roller configurations on scrap
pieces that are the same dimension and material
as the final workpiece.
To create a curve in the workpiece:
1. Use diameter adjustment knobs to lower rear
roller until it is even with bottom roller (see
Figure 15). Rotate thickness adjustment
knobs counterclockwise until top roller can be
lifted enough to insert workpiece.
Performing multiple passes while gradu-
ally reducing curve radius produces better
results than trying to make curve in just one
or two passes.

Initial Flat
Figure 18. Workpiece fed through rollers to
create curved workpiece.
Note: If workpiece has an undesired initial
flat, as illustrated in Figure 18, you can
remove it by flipping workpiece around and
passing it through front of machine so initial
flat enters last.
6. Slightly tighten diameter adjustment knobs in
even amounts, then pass workpiece through
rollers again.
Note: To make a cone, rotate one adjustment
knob more than the other.
7. Repeat Step 5 until you have produced
desired curve.
Rolling Cylinders
This machine can roll flat workpieces into cyl-
inders. Use the formula below to calculate the
length of material needed to create a cylinder from
a piece of flat stock.
C=πD
C=Circumference
(Length of Material Needed)
π=Pi (Approximately 3.14)
D=Diameter
Example: To create a 6" diameter cylinder, use
the above formula as follows:
C=πD
C=3.14 x 6"
C=187⁄8"
The result indicates that you need to start with
a piece of sheet metal approximately 187⁄8" long
in order to create a 6" diameter cylinder (see
Figure 19).

5. Pass workpiece through machine using hand
crank to create curve (see Figure 18).
Note: For best results, make first bend
about 25% of final radius and increase bend
approximately 25% each successive pass
until final radius has been achieved.

ally reducing curve radius produces better
results than trying to make curve in just one
or two passes.
To create a cylinder:
1. Use diameter adjustment knobs to lower rear
roller even with bottom roller (see Figure 20).
Rotate thickness adjustment knobs counter-
clockwise until top roller is raised enough to
insert workpiece.
2. Evenly lower thickness adjustment knobs
until you feel resistance and workpiece is
firmly held between rollers.
3. Turn hand crank clockwise to feed workpiece
through machine until it is approximately half
way through top and bottom rollers.

4. Turn diameter adjustment knobs clockwise
to lift rear roller until desired bend radius is
reached, as illustrated in Figure 21. Always
turn diameter adjustment knobs in equal
amounts so rear roller remains parallel with
front rollers, or there will be a larger radius
on one end of the workpiece than the other,
resulting in a cone shape.
Note: Always err on the side of making the
radius too large rather than too small. It is
easy to the decrease radius but very difficult
to increase it later.
