Manual Brake Installation, Operation, and Maintenance Manual
Page 1
Before using the Roper Whitney manual brake, carefully read and fully understand
the safety precautions outlined in this section. GENERAL PRECAUTIONS pertain to
the general workplace, and to the attitudes and work habits you bring to the job.
SAFETY PRECAUTIONS DURING OPERATION pertain to work on the brake, and are
repeated in other areas of the manual where they pertain.
Do not consider this section to be all-inclusive on the subject of safety. It is
intended to be a general guide to safety practices as they pertain to the machines
covered by this manual. No set of guidelines can substitute for a common-sense,
informed, proficient, safety-conscious attitude on your part.
Notify management or supervision whenever you feel there is any hazard involving
the equipment or the performance of your job.
Never permit untrained individuals to operate this equipment without close
supervision. Be sure you know and understand the task at hand, and the hazards
associated with it.
Observe and follow safety instructions for your work area. Pay special attention
to posted warnings, and warning labels on the equipment. Do not place speed
above safety.
Wear appropriate clothing. Loose or hanging clothing or jewelry, finger rings, etc.
can be hazardous. Use the appropriate safety equipment, such as eye and hearing
protection, and safety-toe shoes. If gloves are worn to protect from cuts, be sure
they are snug-fitting and not likely to be snagged by moving equipment.
Keep the work area neat and orderly. Be sure it is well lit, that extra tools are put
away, trash and refuse are in the proper containers, and dirt, chips or debris have
been removed from the working areas of the machine. Be sure the floor area is
clean and dry, and that extension cords and similar trip hazards have been removed.
Use the proper tools for the job. Inspect them before use to see that they are in good
working condition. Replace broken or defective tools and equipment.
Use only approved cleaning materials: do not use explosive or flammable liquids
to clean the machine. Discard used cleaning materials in the appropriate contain-
ers.
Do not use compressed air to clean debris, chips, dirt, or grit from the machine,
or from your clothing. Remove chips and grit from the machine with a suitable
brush; never with your hands.
GENERAL
PRECAUTIONS

Manual Brake Installation, Operation, and Maintenance Manual
Page 2
Do not attempt to operate the brake in excess of its rated capacity. Do not attempt
to form wire, nails, rods or pipe on the machine.
Avoid any pinch points created by movement of the machine's components.
Exercise care around the bending apron counterweights. Stand clear of the ends
of the brake during the bend cycle or whenever the bending apron is moved. Do
not loosen the set screws securing the counterweight rods while the bending apron
is in the vertical position.
SAFETY
PRECAUTIONS
DURING
OPERATION
WARNING
SERIOUS INJURY MAY OCCUR
The counterweight and rod can drop suddenly through the holder.
Always use the apron lift handles to apply the bending force. Under no circum-
stances use the counterweight rods for leverage. Failure to heed this warning can
cause personal injury or damage to the counterweight rods. Always stand clear of
the apron lift handle travel arc during the bend cycle to avoid being struck by the
handles.
WARNING
SERIOUS INJURY MAY OCCUR
Avoid pinch points created by the clamping and bending components.
Always stand clear of clamping handles. If the brake has not been properly adjusted
for material thickness; clamping action on one end of the brake may cause the
opposite clamping handle to snap forward due to the twisting stress created on the
upper beam. (this can also indicate that the clamping collars need adjustment.
Refer to Section VII, Periodic Maintenance.)When opening the upper beam
make sure the handles are moved to the horizontal position to avoid accidental
forward movement of the handles caused by the weight of the upper beam.
If you observe unusual noises or vibrations during machine operation, check the
machine condition immediately. Do not attempt to operate the equipment further
until the causes of unusual behavior have been found and corrected.

SECTION 2
MACHINE DESCRIPTION
Roper Whitney floor mounted manual bending brakes are precision machines for
use in bending mild steel and other sheet metals, including aluminum, brass,
bronze, copper, duralumin; lead, monel metal, silver, carbon and stainless steel
within rated capacity.
The brakes are rated to form a 1-inch minimum wide flange over entire length of
brake on a single thickness of material of the rated gauge capacity with work angle
support installed. Bending capacities are reduced by four (4) gauges when the
apron work support is removed.
The machines are essentially identical in construction, varying only in length or
capacity. Major components are shown in Figure 1.
Fabricated of sturdy steel plate with appropriate gussets, braces and trusses; three
basic longitudinal members (upper-beam, lower-beam and bending leaf/apron)
control the clamping pressure and stress incurred in overcoming the yield strength
of the material being formed. Provisions for adjusting clamping force and
tensioning of the longitudinal members are incorporated in the design of the
bending brakes.

RECEIVING When you receive your bending brake, check immediately for obvious damage,
which may have occurred during transit, to the skidding material or to the brake
itself. Also check to see that all material listed on the bill of lading is present.
Since Roper Whitney equipment is normally sold F.O.B., factory in Rockford, IL,
our responsibility for transit damage ceases when the transportation company
signs the bill of lading indicating it has received the items listed in good condition.
Report discovered damage or shortages to the carrier. Make a notation on the
delivery waybill, and have the delivering driver sign it, acknowledging the damage
or shortage.
Submit claims for repair or replacement to the carrier; include any extra shipping
charges. Notify Roper Whitney Company promptly of any damage or shortages.
If you discover concealed damages or shortages after the carrier has departed, you
may still file a claim for concealed damage. This should be done as quickly as
possible. Again, notify Roper Whitney Company promptly of such damages or
shortages.
The brake is shipped on a skid of 3" x 6" wood timbers. It is secured to this skid
with four (4) carriage bolts, which should remain secured while the machine is
unloaded and moved about. The skid and brake may be moved using a suitable fork
lift.
UNPACKING The two counterweight arms (rods) and their counterweights are mounted
separately on the wooden skid for shipment. Remove these from the skit and set
to one side.
SECTION 4
RECEIVING AND INSTALLATION
UNLOADING
WARNING
WHEN IN MOTION, THE SKIDDED BRAKE MAY BE TOP HEAVY
When lifting or moving the skidded brake with a forklift, secure the brake laterally to
the forklift.
WARNING
THE COUNTERWEIGHT ARMS AND COUNTERWEIGHTS ARE
HEAVY
Use care when removing them from the skid to avoid injury.

The clamping handles at each end of the brake are wrapped and wired in the down
position to prevent damage and to prevent the handles from being used to move
the brake. Remove the wires and wrapping.
Wooden blocks are positioned between the upper and lower beam jaws to prevent
damage during shipment. Lift the clamping handles and remove the blocks.
The bending leaf (apron), is wired to the center truss stud of the lower beam to
prevent movement during transit. Remove the wire.
Remove the four (4) carriage bolts, nuts, and washers securing the brake to the
skidding. DO NOT REMOVE THE BRAKE FROM THE SKID AT THIS
TIME.
Manual Brake Installation, Operation, and Maintenance Manual
Page 6
WARNING AND CAUTION
SERIOUS INJURY CAN RESULT OR THE BENDING BRAKE CAN BE
DAMAGED
Do not operate the brake on the skid. The brake must be attached to the floor. The
machine is topheavy and can tip if not securely anchored. The skid does not provide
a suitable anchoring platform.
SITE
PREPARATION
The brake must be placed on a firm floor which does not sag and which does not
have any "spring" to it. The floor must be generally level, with no twisting or
unevenness in the surface. The floor must also be capable of accepting 1/2-inch lag
screws or bolts for the purpose of securing the brake.
There must be adequate area around the brake for free movement of the operator
and the handling of large sheets of metal. Allow 4 to 6 feet behind the brake, 6 to
8 feet in front of the brake, and 3 feet on either end of the brake.
To move the brake off the skid, and to its mounting position, use an overhead crane
or a fork lift with the forks above the brake. If a fork lift is used, secure a lifting
hook on the lift forks. Pass a sling under brake and secure each end on the lifting
hook as shown in Figure 2.
CAUTION
THE BENDING BRAKE CAN BE DAMAGED
Do not move the brake using lift truck forks directly under any machine members.

INSTALLING THE
COUNTER-
WEIGHTS
Have an assistant raise the bending apron to the horizontal position, and hold it in
that position while the counterweights are installed.
Install a counterweight in the mounting hole in each end of the bending apron.
Adjust the counterweights so that they balance the bending aparon in the
horizontal position.
Tighten two set screws securely on each counterweight shaft.
WARNING
THE COUNTERWEIGHTS ARE HEAVY
Use care when installing the counterweights to avoid injury. Be sure the set screws
are tightened enough so the counterweights will not drop when the bending apron is
returned to the vertical position.

Be sure the gauge thickness of the material to be formed to is within the rated
capacity of the machine. Then adjust clamping pressure as follows:
1. At each end of the brake, loosen both toggle pin lock nuts slightly before
beginning adjustment (see Figure 3).
2. Place small sample pieces of the material to be formed between the upper
beam radius bar and the bed at each end of the machine. Clamp in position.
3. At each end of the machine, tighten the lower toggle pin lock nut against
the toggle anchor just enough to hold material firmly when the clamp-
ing lever is against the forward stop (see Figure 3).
Manual Brake Installation, Operation, and Maintenance Manual
SECTION 5
SETUP
The machine has been adjusted and pretensioned at the factory. Set-up adjust-
ments are for clamping pressure, material thickness, setting up for narrow or offset
bends, setting bend angle control, and setting up of the optional rear material stops.
Excessive clamping pressure is not required or desirable. It has a tendency to
counteract the normal preloading adjustments and may interfere with obtaining
straight and uniform bends. Use only enough clamping pressure to keep the
material from slipping.

4. At each end of the machine, tighten upper toggle pin lock nut against
the toggle anchor (see Figure 3).
5. At each end of the machine, pull the clamping lever forward against the
stop. Each end should require equal effort. Adjust one end, if necessary,
according to the general procedure above.
Under normal circumstances, clearance between the apron edge and the upper
beam radius bar should be approximately (2) times the material thickness for 16
ga. mild steel. For lighter gauge material, less clearance is required. One and a half
(1-1/2) times material thickness is usually sufficient. Soft material, such as
aluminum, may be formed with a clearance equal to the material thickness.

Remove the bending reinforcing angle and the bending bar as follows:
1. Support the bending reinforcing angle and remove retaining screws.
Withdraw the angle from the machine (see Figure 5).
2. Support the bending bar and remove retaining screws. Withdraw the
bar from the machine (see Figure 5).
3. After the bending operation is complete, be sure to replace the removed
components, attaching them with the retaining screws. Tighten the screws
securely.
Manual Brake Installation, Operation, and Maintenance Manual
3. Move the upper beam forward or back until proper clearance is achieved
by turning the thickness adjusting screw located at rear of the leg bracket
on each end of the machine (see Figure 4). Final adjustment must always
be toward the front of the brake to remove backlash from the adjusting
screws.
4. Retighten the clamping screw on each end of the machine (see Figure 4).
It is sometimes necessary to remove the bending reinforcing angle to make narrow
or offset bends. In extreme conditions, it may also be necessary to remove the
bending bar. The bending bar is made of tough, wear resistant material to protect
the edge of the apron and should be removed only when absolutely necessary to
make tight reverse bends.
Removing the bending reinforcing angle reduces capacity by four (4) gauges. The
rated 16 ga. capacity is reduced to 20 ga. capacity. Removing both the bending
reinforcing angle and the bending bar reduces the 16 ga. capacity to 24 gauge
capacity.

The bend angle stop can be adjusted for multiple or precision bends.Adjust the
angle stop as follows:
1. Loosen the angle stop collar set screw and move the angle stop collar out
toward the end of the angle stop rod. (See Figure 4.)
2. Have an assistant move the apron to the desired position and hold it while
you adjust the collar. Be sure to take spring-back into account when setting
the angle.
3. Move the angle stop collar against the angle stop stud and tighten the angle
stop collar set screw to retain it in that position.
SETTING UP THE
OPTIONAL REAR
MATERIAL
STOPS
For repeat operations involving deeper bends, it may be useful to use the optional
rear material stops.
Figure 6. Installing and Adjusting the Optional Rear Material Stops.
Install and adjust the rear material stops as follows:
1. At each end of the machine, insert a threaded stop rod. Secure the stop rod
using the stop rod lock nuts (see Figure 6).
2. Adjust a stop nut on each stop rod to the desired position. Be sure that both
stop nuts are the same distance from the front of the machine. (Anglular
bends not perpendicular to the material edges can be made by offsetting
one stop nut from the other. This will reduce the overall width which can
be bent.) (See Figure 6.)
3. Lock each stop nut in place using a stop lock nut (see Figure 6).

OPERATION
GENERAL
INSTRUCTIONS
Operation of the brake is entirely manual, and the operator has full control of the
operation at all times.
Do not attempt to operate the brake in excess of its rated capacity. Do not attempt
to form wire, nails, rods or pipe on the machine.
If you are bending large sheets of material which are difficult to handle, you may
wish to use an assistant to help in loading, clamping, and bending.
If you observe unusual noises or vibrations during machine operation, check the
machine condition immediately. Do not attempt to operate the equipment further
until the causes of unusual behavior have been found and corrected.
CLAMPING THE
MATERIAL
Insert the material to be bent under the upper beam clamping mechanism, lining up
both sides so they are even with the upper beam. Position short pieces of material
in the center of the brake to equalize strain during bending.
Clamp the material by lowering the upper beam with the clamping levers.
If the brake has not been properly adjusted for material thickness; clamping action
on one end of the brake may cause the opposite clamping handle to snap forward
due to the twisting stress created on the upper beam.
When opening the upper beam make sure the handles are moved to the horizontal
position to avoid accidental forward movement of the handles caused by the weight
of the upper beam.
WARNING
PINCH POINTS CAN CAUSE SERIOUS INJURY
Avoid any pinch points
created by movement of the machine's components.
WARNING
THE UPPER BEAM CLAMPING MECHANISM CAN CAUSE SERIOUS
INJURY
Always stand clear of clamping handles. Do not place fingers near or under the upper
beam.
Page 13

Manual Brake Installation, Operation, and Maintenance Manual
BENDING THE
MATERIAL
Bend the material to the desired bend angle using the apron lift handles to apply
the bending force. Under no circumstances use the counterweight rods for
leverage.
If the material being bent is long and protrudes from the machine, lift it during the
bending operation to avoid creases or crimps caused by material weight.
BENDING OF
MULTIPLE
THICKNESSES
To avoid adjusting for every piece on a run of parts, do all the single-thickness
bending operations first, then adjust and do the multiple thickness bending.
Never bend against hems or seams until an adjustment has been made to compensate
forthe clampingofmultiple thicknessesofmaterial. Neverbendagainst hemsorseams
untiltheupper beamisset backforclearanceofthemultiplethicknesses ofmaterial.See
SETUP, SECTION 5, foradjustment instructions.
CAUTION
MACHINE COMPONENTS CAN BE DAMAGED
Failure to compensate for multiple thicknesses of material may result in breakage of
the clamping mechanism.
Failure to set the upper beam back for extra clearance may result in indentations on
the upper beam jaw.
CAUTION
THE COUNTERWEIGHT RODS CAN BE DAMAGED
Using the counterweight rods to apply bending force can damage them.
WARNING
THE COUNTERWEIGHTS AND CLAMPING HANDLES
CAN CAUSE INJURY
Always stand clear of the ends of the brake during the bend cycle.
Always stand clear of the apron lift handle travel arc during the bend cycle.
