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 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-

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 work­piece 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 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.

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.

CHECK DAMAGED PARTS. Regularly inspect
machine for any condition that may affect safe
operation. Immediately repair or replace damaged
or mis-adjusted parts before operating machine.

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.

GUARDS & COVERS. Guards and covers reduce
accidental contact with moving parts or flying
debris. Make sure they are properly installed,
undamaged, and working correctly.

Additional Safety for Slip Rolls

METAL EDGES. Sharp edges on sheet metal can

result in severe cuts. Always wear leather gloves
and buttoned long-sleeves when working with
sheet metal. Always chamfer and debur metal
edges.

BACK INJURIES. The cranking motion required
to operate this slip roll is potentially harmful if
proper technique is not used. To avoid back inju­ries, keep your back vertical and never over-exert
yourself or operate the slip roll in awkward posi­tions.

CRUSHING & PINCHING INJURIES. Slip rolls
can quickly crush or pinch fingers or hands. Never
place fingers or hands between or near the rollers
during operation.

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.

SECURING SLIP ROLL. Before using, secure

the slip roll to the floor so it can withstand the
dynamic forces involved with forming sheet metal.
Otherwise, it may move or tip during operation,
causing serious injury or property damage.

TOOLS IN POOR CONDITION. Using the slip
roll with loose or damaged hardware could result
in sudden, uncontrolled movements during use.
Inspect the slip roll for any cracked linkage, con­trols, or loose fasteners. Correct any problems
before use.

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.

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:

Anchoring to 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.

Assembly

Number of Mounting Holes ............................ 8

Diameter of Mounting Hardware .................

The Model T26471 is top heavy and may tip
as a result of the dynamic forces necessary for
operation. This machine must be anchored to the
floor to prevent tipping or shifting. Because floor
materials may vary, floor mounting hardware is
not included.

Severe injury may occur from slip roll tip­ping over. Anchor slip roll to floor to prevent
tipping as a result of lateral force needed to
operate this machine.

This slip roll can be used to flat roll sheet metal up
to 15 gauge. This can be done to straighten sheet
metal that is slightly out of form.

Note: Plastic deformation is permanent. Once a
workpiece has been sharply creased or bent, it
cannot be straightened using this slip roll.

The main rollers of this
machine present a pinch­ing hazard. Make sure no
body part or clothing is
near the area between the
rollers. Failure to follow this
warning may result in fin­gers, hair, or clothing being
pulled into the machine,
causing personal injury.

To flat roll a workpiece:

1. Place workpiece between top and bottom

rollers, as shown in Figure 11. Turn thick­ness adjustment knob to lift bottom roller until
workpiece is held snug between top and bot­tom rollers.

completely (see Figure 12).

Creating Bends

This slip roll can create constant-radius bends in
sheet metal up to 15 gauge.

Note: The method for creating a specific radius is
a trial-and-error process. Due to the many varia­tions among metal workpieces, no single position­ing will create the same curve on all materials. We
recommend using scrap pieces the same dimen­sions and material as the final workpiece until the
desired curve is achieved.

its leading edge is directly above rear roller,
as shown in Figure 15.

Figure 15. Feeding the workpiece.

3. Turn radius adjustment knobs to lift rear roller

until desired radius bend is reached (see
Figure 16). Make sure to turn knobs equal
amounts so rear roller is always parallel
with other rollers. Failure to do so will create
a larger radius on one end than the other,
resulting in a cone or spiral shape.

This machine poses a cut­ting hazard if workpieces
are not properly handled. If
necessary, get assistance
to support workpiece. Make
sure all helpers are wearing
leather gloves and safety
glasses when assisting in
use of this machine.

Depending on size and shape of workpiece,
you may need assistance to support
workpiece as it exits machine. Failure to
adequately support workpiece may result in
workpiece falling, causing injuries.

4. Turn crank to process material through slip

roll. Continue turning until workpiece is com­pletely through top and bottom rollers (see

Note: The method for creating a specific radius is
a trial-and-error process. Due to the many varia­tions among metal workpieces, no single position­ing will create the same curve on all materials.

To create a cylinder:

1. Place workpiece between top and bottom

rollers, as shown in Figure 19. Turn thick­ness adjustment knob to lift the bottom roller
until workpiece is held snug between top and
bottom rollers.

7

The result of 18

⁄8" indicates that you need to start

with a piece of sheet metal that is approximately

7

⁄8" in length to create a 6" diameter cylin-

18
der.

You can use the slip roll to create a bend with the
correct radius so that the two ends meet, forming
a 6" diameter cylinder (see Figure 18).

2. Turn crank clockwise to feed workpiece until

CW

it is approximately halfway through rollers.

3. Turn radius adjustment knobs to lift rear roller
until desired radius bend is reached (see
Figure 20). Make sure to turn knobs equal
amounts so rear roller is always parallel
with other rollers. Failure to do so will create
a larger radius on one end 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 decrease the radius but very difficult
to increase the radius later.

5. Rotate workpiece 180˚, insert curved end
into slip roll, then process workpiece through
machine, as shown in Figures 22–23.

6. Continue to process workpiece until cylinder
is formed, as shown in Figure 24.

Bending Wire

—If ends of cylinder do not meet, lift rear roll-

er equally at both ends, then process entire
cylinder through slip roll again. Repeat as
necessary.

—If ends of cylinder overlap, remove cylinder

as described in Removing Workpiece on
Page 20. Then, either attempt to increase
radius by manually bending it, or scrap
workpiece and start at Step 1 with a new
workpiece.

CW

This slip roll can be used to shape wires, rods,
and small-diameter tubing. The wire grooves can
also be used when rolling sheet metal that has a
wire bead at one end.

To use the wire grooves:

1. Place workpiece into smallest possible groove

5

on wheel. The three sizes are

⁄16", 3⁄8", and 1⁄2"

(see Figure 25).

Example: Suppose you want to bend a piece

1

⁄4" rod. Though it would fit in any of the

of
three grooves, you would use the

5

⁄16" groove
since it is the smallest possible groove that
the rod will fit into.

counterclockwise until roller handle can be
pulled down and flat edges of upper roller
bracket are parallel with slots in frame.

3. Rotate handle upward to its vertical position
and tighten thumb screw to secure top roller
(see Figure 28).

SECTION 5: MAINTENANCE

Schedule

For optimum performance from your machine,
follow this maintenance schedule and refer to any
specific instructions given in this section.

Daily Check

• Loose mounting bolts.

• Damaged rollers

• Any other unsafe condition.

Weekly Maintenance:

• Clean machine.

• Lubricate gears.

• Lubricate roller bushings.

Lubrication

Gears

Remove the 5mm cap screws on the gear guard
cover, remove it, and apply a dab of NLGI#2 or
equivalent grease to the upper roller gears (see
Figure 36). Rotate the hand crank several times
in both directions to distribute the grease to all
gears, then wipe away any excess and re-attach
the cover.

Roller Bushings

Use an oil can to apply a few drops of ISO 32 or
equivalent oil to the brass bushings of the three
rollers on the right side and into the ball oiler on
the top of the left side (see Figures 37–38). Rotate
the hand crank several times in both directions to
distribute the oil, then wipe away any excess.

Roller Bushings

Cleaning

Cleaning the Model T26471 is relatively easy.
Periodically wipe down the rollers to remove dust
and debris—this ensures rust-promoting material
does not remain on the bare metal surfaces.

Treat all unpainted metal surfaces with quality
metal protectants like SLIPIT
(see previous page for offerings from Grizzly).
