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.

If the clamping pressure has been adjusted
(see Adjusting Clamping Pressure, Page 18.) We recommend using the foot pedal lock for better control when bending workpieces
You can lower the fingers onto the workpiece
without locking the foot pedal. However, you will have to keep the foot pedal depressed while moving the bending wing during bend ing operations.
To release the foot pedal lock:
1. Press the foot pedal lock down to release the
foot pedal. The pedal will raise back to its original position (
Figure 15).

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 in Figure 20.

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!
20 G0578 40" Pan and Box Brake
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
Steps 1-5

Page 23
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.

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.
