Site Considerations
Continued on next page
Floor Load
Your Model G0578 weighs approximately 627
lbs. and has a footprint of 46
concrete floors should be sufficient to carry the
weight. BEFORE moving the brake onto a wood
floor, inspect it carefully to determine that it will
be sufficient to carry the load of the machine, the
lifting device and its operators. If you question the
strength of your floor, you should consider having
it inspected for possible reinforcement.
Working Clearances
Working clearances can be thought of as the
distances between machines and obstacles that
allow safe operation of every machine with
out limitation. Consider existing and anticipated
machine needs, size of material to be processed
through each machine, and space for auxiliary
stands or work tables. Also consider the relative
position of each machine to one another for efficient material handling.

Bolting to Concrete Floors
Lag shield anchors with lag bolts (Figure 9) and
anchor studs (Figure 10) are two popular meth
ods for anchoring an object to a concrete floor.
We suggest you research the many options and
methods for mounting your pan and box brake
and choose the best that fits your specific appli
cation.
Note—Anchor studs, as shown in Figure 10, are
stronger and more permanent alternatives to lag
shield anchors; however, they will stick out of the
floor, which may cause difficulties if you decide
to move your pan and box brake at a later point.

Adjusting Clamping
Continued on next page
Pressure
Aligning Fingers
Finger alignment is critical for accurate results.
The correct clamping pressure depends on the
workpiece thickness. The ideal pressure will
have medium/hard resistance and will lock the
workpiece into position easily—much like a pair
of vice grips. This pressure is adjusted by moving
the clamping pressure adjusting nuts, shown in
Figure 16, located on both sides of the pan and
box brake.
Tools Needed: QTY
8MM Hex Wrench ..............................................
To align a finger:
1. Disengage the foot pedal.
2. Lower the bending leaf.
3. Loosen the cap screw(s) on a finger enough
to move it up or down without resistance.
4. Push the finger firmly up against the lower
edge of the clamping leaf and tighten the cap
screw(s), as shown in
Figure 17.

Spacing Fingers
The fingers can be spaced apart for clearance
when making pans or boxes. This requires
removing one or more of the fingers so that you
can space the others to match the width of your
pan or box
Tools Needed: QTY
8MM Hex Wrench ..............................................
To space the fingers apart:
1. Remove the cap screws from each of the
fingers you decide to remove.
2. Pull the fingers off the front guide, as shown
in Figure 19, and set them aside.
Note—You may need to mix and match finger
widths to equal the size of your workpiece.

Basic Bending
Do not operate the Model G0578 unless it has
been securely clamped in place or mounted
to the floor, or it could tip over on you, caus
ing a severe injury!
Setting Adjustable
Stop
The Model G0578 features an adjustable stop
so you can make repeated bends at the same
angle.
To set the adjustable stop:
Bending operations require the fingers to be
parallel with the edge of the clamping block and
require the setback and clamping pressure to
be correctly adjusted for the thickness of the
workpiece.
To perform a basic bending operation:
1. Open the clamping leaf.
2. Insert the workpiece between the fingers and
the clamping block.
3. Align the fingers to the bend mark on the
workpiece, and clamp it in place.
Note—If the foot pedal does not lock when
you lower the fingers over the workpiece, the
clamping pressure may need to be loosened.
(See Adjusting Clamping Pressure, Page
18).
4. Lift the bending leaf until the workpiece has
reached the desired bend angle.
1. Rotate the bending leaf to the desired bending angle.
2. Make sure the stop collar is snug against the
stop block.
3. Tighten the stop collar cap screw, as shown

5. Raise the clamping leaf and remove the bent
workpiece.
Note—If a pan or box bend is desired, choose a
finger or a selection of fingers that are as close
as possible to the length of the pan or box side
lengths.
Hold onto the workpiece so it does not drop
and hit you when it is released!

4. Check that the stop collar is locked by moving
the bending leaf up and down.
5. To make fine adjustments to the bending
angle, turn the stop block cap screw clock
wise or counterclockwise, then tighten the
jam nut against the casting.
6. To select and lock a different bending angle,
loosen the stop collar cap screw and repeat

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 over
all length and width of the blank needed to make
a particular part.
Exact allowances can only be obtained by trial
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.

SECTION 4: MAINTENANCE
Lubrication
There are four main areas to keep lubricated on
the Model G0578 Pan and Box Brake: 1) The
unpainted cast iron surfaces, 2) the bending leaf
hinge, 3) clamping leaf grease fittings, and 4) the
setback knob threads.
Cast Iron Surfaces
To prevent rust, all unpainted cast iron surfaces
on the Model G0578 should be regularly main
tained with a surface protectant like G96
TREATMENT (Model H3788) or BOESHIELD
T-9 (Model G2871).
Note—Check with the current Grizzly catalog for
current pricing and a variety of other quality metal
protectants.
Clamping Leaf
There are two grease fittings for the clamping
leaf (see Figure 21). They should be greased at
least once a week. Grease daily if your machine
is under heavy, continuous use.

Bending Leaf
Place an occasional dab of white lithium grease
on the bending leaf hinge (Figure 22).

Setback Knob Threads
The threads on the setback knobs (see Figure
23) may need an occasional dab of white lithium
grease. The threads are easiest to reach if the
setback is moved all the way forward or all the
way backward. For best results, move the setback
all the way back and forth one time after applying the grease; grease the threads as needed to
maintain smooth operation from the knobs.
