Cleanup
Gasoline and petroleum
products have low flash
points and can explode
or cause fire if used to
clean machinery. Avo i d
u sing t h e s e p r o d u c t s
to c l e a n m a c hin e r y.
The unpainted surfaces of your machine are
coated with a heavy-duty rust preventative that
prevents corrosion during shipment and storage.
This rust preventative has been your machine's
close ally and guardian since it left the factory.
If your machine arrived to you free of rust, then
be thankful that the rust preventative protected
it during its journey...and try to stay thankful as
you clean it off, because it can be challenging to
remove if you are unprepared and impatient.
Many cleaning solvents
are toxic if inhaled.
Minimize your risk by only
using these products in a
well ventilated area.
Plan on spending some time cleaning your
machine. The time you spend doing this will
reward you with smooth sliding parts and a better
appreciation for the proper care of your machine's
unpainted surfaces.
Although there are many ways to successfully
remove the rust preventative, these instructions
walk you through what works well for us.
Before cleaning, gather the following:
•
Disposable Rags
•
Cleaner/degreaser (see below)
•
Safety glasses & disposable gloves
H9692—Orange Power Cleaner & Degreaser
One of the best cleaners we've found for quickly
and easily removing rust preventative.
Figure 3. Model H9692 Industrial Orange Power
Cleaner/Degreaser (99.9% biodegradable).
Note: In a pinch, automotive degreasers, mineral
spirits or WD•40 can be used to remove rust preventative. Before using these products, though,
test them on an inconspicuous area of your paint
to make sure they will not damage it.
T23035 60" Hand Brake
NOTICE
Avoid chlorine-based solvents, such as
acetone or brake parts cleaner that may
damage painted surfaces. Always follow
the manufacturer’s instructions when using
any type of cleaning product.
Basic steps for removing rust preventative:
1.
Put on safety glasses and disposable
gloves.
2.
Coat all surfaces that have rust preventative
with a liberal amount of your cleaner/degreaser and let them soak for few minutes.
3.
Wipe off the surfaces. If your cleaner/degreaser is effective, the rust preventative will wipe
off easily.
Note: To clean off thick coats of rust preventative on flat surfaces, such as tables, use
a PLASTIC paint scraper to scrape off the
majority of the coating before wiping it off with
your rag. (Do not use a metal scraper or you
may scratch your machine.)
4.
Repeat Steps 2–3 as necessary until clean,
then coat all unpainted surfaces with a quality
metal protectant to prevent rust.

Site Considerations
Physical Environment
Weight Load
The physical environment where your machine
is operated is important for safe operation and
the longevity of its components. For best results,
operate this machine in a dry environment that is
free from excessive moisture, hazardous chemicals, airborne abrasives, or extreme conditions.
Extreme conditions for this type of machinery are
generally those where the ambient temperature
range exceeds 41°–104°F; the relative humidity
range exceeds 20–95% (non-condensing); or the
environment is subject to vibration, shocks, or
bumps.
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 workpiece that will be used. Additionally, consider the
weight of the operator and any dynamic loading
that may occur when operating the machine.
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 maintenance and service described in this manual.
See below for required space allocation.
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.
Children or untrained people
may be seriously injured by
this machine. Only install in an
access restricted location.

Moving & Placing
Machine
The Model T23035 is a
heavy machine. Serious
personal injury may occur
if safe moving methods
are not used. To be safe,
get assistance and use
power equipment to move
the shipping crate and
remove the machine from
the crate.
Mounting to Shop
Floor
To prevent the hand brake from tipping over
from the dynamic forces during operation, it is
required that you mount the hand brake to the
floor. Because floor materials vary, floor mounting
hardware is not included.
Bolting to Concrete Floors
Anchor studs and lag shield anchors with lag bolts
(see Figure 5) and are two popular methods for
anchoring an object to a concrete floor. We suggest you research the many options and methods
for mounting your machine and choose the best
that fits your specific application.
Remove the shipping crate from the pallet, then
remove the screws that secure the machine to
the pallet.
Use a forklift to lift the machine from the pallet and
move it to a suitable location. Before using the
machine, mount it to the floor.
Do not operate the Model T23035 unless
it has been securely mounted to the floor.
During use it could tip over and fall, causing
property damage or injury.

SECTION 3: OPERATIONS
Basic Controls
To reduce the risk of
serious injury when using
this machine, read and
understand this entire
manual before beginning
any operations.
Damage to your eyes and hands could result
from using this machine without proper protective gear. Always wear safety glasses and
heavy gloves when operating this machine.
Refer to Figures 6–7 and the following descriptions to become familiar with the basic controls of
your hand brake.
Setback Wheel: Adjusts the setback of the
clamping leaf for the workpiece thickness and
desired crease radius.
Turn-buckle: Adjusts the height of the clamping
leaf for workpiece thickness.
Setback Wheel
Loose hair, clothing, or
jewelry could get caught
in machinery and cause
serious personal injury.
Keep these items away
from moving parts at all
times to reduce this risk.
NOTICE
If you have never used this type of machine
or equipment before, we strongly recommend that you read books, trade 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.

T23035 60" Hand Brake
Adjusting Setback
To adjust the setback:
1.
Before beginning bending operations, consider the
differences in sheet metal gauges when trying to
achieve either sharp or rounded bends, and allow
for the differences by adjusting the setback.
Setback Wheel
(1 of 2)
The setback (A) is the distance from the forward
edge of the clamping leaf to the edge of the
clamping block, as shown in Figure 8. The setback distance is determined by the gauge of the
workpiece and the desired radius of the bend.

Figure 8. Setback distance.
Normally, setback (A) is adjusted at least 11⁄2–2
times the workpiece thickness (B). Thicker or
tempered workpieces will need a larger setback.
NOTICE
You must include the thickness of folded
edges or joints when determining the proper setback, or the brake may be damaged.
Figure 9. Setback wheel (left side shown).
2.Rotate the two setback wheels equal amounts.
Turning the wheels one way will move the
clamping leaf forward. Turning them the
other way will move the clamping leaf backward. (Because the adjusting mechanism is
an eccentric, turning the adjusting wheels a
full turn will only bring the clamping leaf to its
original position.) Be sure the setback is set
evenly across the clamping leaf.
3.
Lower the clamping leaf over the clamping
block, then check for setback distance.
4.
Repeat Steps 1–3 until the desired setback is
achieved.
Note: After performing these adjustments,
make sure the clamping leaf is parallel with
the bending leaf, or your bend will be distorted (see Figure 10).

Correct: Clamping Leaf and
Bending Leaf are parellel
Incorrect: Clamping Leaf and

Adjusting Clamping
Pressure
3.
The clamping pressure must be adjusted for different workpiece thicknesses. The ideal pressure
will have medium resistance at the clamp handle,
and will lock the workpiece into position easily.
This pressure is controlled by adjusting the turnbuckles located at each end of the machine.
Workpiece
Lock Nuts
To adjust the clamping pressure:
Turn-buckle
1. Lower the bending leaf onto the workpiece. It
is best if the workpiece is the same width as
the bench hand brake. This will ensure that
the clamping pressure is set evenly across
the machine. If the workpiece is not the same
width as the machine, place two pieces of
metal the same thickness as the workpiece
at each end.
2.
-14-
When the clamping leaf is just touching the
workpiece, the clamping leaf handle should
be between the 7 and 8 o'clock position
(angled below horizontal). This position will
apply the optimal clamping force and minimize the likelihood of loosening.
Use a 24mm wrench to loosen the upper
and lower lock nuts shown in Figure 11, and
adjust the turn-buckle until the clamp handle
is in the 7–8 O'clock position (as shown)
when the clamping leaf just touches the
workpiece.
Clamping Leaf
Handle
Figure 11. Clamping pressure adjustment.
4.
Tighten the lock nuts to ensure that the position is maintained.
5.
Make sure the clamping pressure is even on
both ends of the workpiece.
6.
Make adjustments as needed for sufficient
and even clamping pressure, repeating Steps
3–5.
T23035 60" Hand Brake
Basic Bending
Do not operate the Model T23035 unless
it has been securely mounted to the floor.
During use it could tip over and fall, causing
property damage or injury.
Note: If the handle does not clamp the
workpiece when you lower the clamping leaf
over the workpiece, the clamping pressure
will need to be increased. (See Adjusting
Clamping Pressure on Page 14.)
4.
Lift the bending leaf until the workpiece has
reached the desired bend angle, then lower
the bending leaf (see Figure 13).
Bending operations require that the clamping leaf
be parallel with the edge of the clamping block
and that the setback and clamping pressure
are correctly adjusted for the thickness of the
workpiece.
To perform a basic bending operation:
1.
Raise the clamping leaf.
2.Insert the workpiece between the clamping
leaf and the clamping block.
3.
Align the area on the workpiece to be bent
with the edge of the clamping leaf and clamp
the workpiece in place using the clamping
leaf handle (see Figure 12).
Figure 13. Bending workpiece.
5.Raise the clamping leaf handle to release the
workpiece from the machine.
Bending Allowance
To bend metal objects accurately, you need to
consider the total length of each bend, especially
when more than one bend is required. This is
called bend allowance.
Subtract bend allowance from the sum of the
workpiece outside dimensions to obtain the overall length and width of the blank needed to make
a particular part.
Figure 12. Clamping workpiece.
T23035 60" Hand Brake
Exact allowances can only be obtained by trialand-error due to differences in sheet metal hardness, whether the bend is with or across the grain,
and difficulties in making an exact bend radius.
Bend allowances accurate enough for average
use may be found in metalworking handbooks.

Angle Stop
The Model T23035 has an angle stop to efficiently create the same angle bend in multiple
workpieces.
Note: The angle indicated by the scale may not
reflect the final angle of the workpiece once the
workpiece is removed from the machine. This is
due to the variation in malleability and "spring" in
different materials and in workpieces of different
dimensions. An amount of trial-and-error may be
required.
Spring-Assist
Adjustment
The Model T23035 is equipped with a springassist mechanism to reduce the effort required
to create bends. If you find that the spring assist
is not correct for the thickness material you are
bending, you can adjust the level of assist.
To adjust the spring-assist:
1.
Loosen the spring bracket hex bolt (see
Figure 15).
To adjust the angle stop:
1.
Loosen the hex bolt on the angle stop to
release it (see Figure 14).

2.
Note: With the spring bracket hex bolt loosened, the bending leaf should move without
rotating the spring bracket. If the spring
bracket still moves with the bending leaf, use
a dead blow hammer to loosen the spring
bracket so it rotates freely on the bending leaf
shaft.
Figure 14. Angle stop.
2.
Bend a workpiece to the desired angle.
While still holding the bending leaf at that
angle, have an assistant place the angle stop
against the pointer.
3.
For each following bend, lift the bending leaf
until the pointer reaches the angle stop.
Have an assistant hold the bending leaf at an
angle of about 45°.
3.
Re-tighten the spring bracket hex bolt.
4.Repeat Steps 1–3, if necessary, until the
desired spring tension is achieved.
—To increase the tension, have your assistant hold the bending leaf higher while you
tighten the spring bracket hex bolt.
—To decrease the tension, have your assistant hold the bending leaf lower while you
tighten the spring bracket hex bolt.

SECTION 5: MAINTENANCE
Schedule
Lubrication
For optimum performance from your machine,
follow this maintenance schedule and refer to any
specific instructions given in this section.
Lubricating the Model T23035 consists of applying lubricant to the cam wheels, bushings, and the
hinge pins.
Daily Check:
•Loose mounting bolts.
•Damaged dies
•
Any other unsafe condition.
Oiling Locations
Weekly Maintenance:
•
Clean machine.
•
Lubricate apron pivots.
•
Lubricate bushings.
Apply several drops of SAE 30 or equivalent
oil from an oil can into the oil holes shown in
Figure 24. Move each component back-and-forth
several times to disperse the oil, then wipe off
excess oil. Be sure to lube the oil holes on both
sides of the machine.
Cleaning
Cleaning the Model T23035 is relatively easy.
Periodically wipe down the machine to remove
dust and oil. Treat all unpainted surfaces with a
non-staining lubricant after cleaning.
Unpainted Surfaces
Figure 24. Oil locations (left side shown).
Protect the unpainted surfaces on the machine by
wiping it clean after every use—this ensures rustpromoting debris does not remain on bare metal
surfaces.
Keep the machine rust-free with regular applications of products like Boeshield ® T-9 (see Section
4: Accessories on Page 17 for more details).
