3.0 Safety Warnings

1. Read and understand entire owner’s manual before attempting assembly or operation.

2. Read and understand the warnings posted on the machine and in this manual. Failure to comply with all of these warnings may cause serious injury.

3. Replace warning labels if they become obscured or removed.

4. This box and pan brake is designed and intended for use by properly trained and experienced personnel only. If you are not fam iliar wit h t he p ro p er and sa fe operation of a brake, do not use until proper training and knowledge have been obtained.

5. Do not use this machine for other than its intended use. If used for other purposes, JET disclaims any real or implied warranty and hold s itself harmles s from a ny injury t hat may result from that use.

6. Do not exceed the rated capacity of the brake.

7. Always wear approved safety glasses/face shields while using this machine. Everyday eyeglasses only have impact resistant lenses; they are not safety glasses.

8. Before operating this brake, remove tie, rings, watches and other jewelry, and roll sleeves up past the elbows. Do not wear loose clothing, and confine long hair. Non-slip footwear or anti-skid floor strips are recommended.

9. Some dust created by power sanding, sawing, grinding, drilling and other construction activities contains chemicals known to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:

• Lead from lead based paint.

• Crystalline silica from bricks, cement and

other masonry products.

• Arsenic and chromium from chemically

treated lumber.

Your risk of exposure varies, depending on how often you do this type of work. To reduce your exposure to these chemicals, work in a well-ventilated area and work with approved safety equipment, such as face or dust masks that are specifically designed to filter out microscopic particles.

10. Do not operate this machine while tired or under the influence of drugs, alcohol or any medication.

11. R emove adjusting keys and wrenches. Form a habit of checking to see that keys and adjusting wrenches are removed from the machine before using.

12. Sheet metal stock has sharp edges. Use leather gloves when handling.

13. Keep hands and fingers clear of area in front and rear of brake.

14. This box and pan brake should be sec ured to the floor to prevent tipping.

15. Keep safety guards in place at all times when the machine is in use. If removed for maintenance purposes, use extreme caution and replace the guards immediately after maintenance is complete.

16. Provide for adequate space surrounding work area and non-glare, overhead lighting.

17. Keep the floor around the machine clean and free of scrap material, oil and grease.

18. Keep visitors a safe distance from the work area. Keep children away.

19. Give your work undivided attention. Looking around, carrying on a conversation and “horseplay” are careless acts that can result in serious injury.

20. Mai ntain a balanced stance at all times so that you do not fall or lean against moving parts. Do not overreach or use excessive force to perform any machine operation.

21. Use the right tool at the correct speed and feed rate. Do not force a tool or attachment to do a job for which it was not designed. The right tool will do the job better and more safely.

22. Do not stand on machine. Serious injury could occur if machine tips over.

Familiarize yourself with the following safety notices used in this manual.

This means that if precautions are not he eded, it may result in minor injury and/or possible machine damage.

7.2 Unpacking and cleanup

Insp ect co nte nt s of sh ipp ing co nta ine r f or ship pi ng damage. Report any damage to your distributor. Remove all contents from carton, and compare to the contents list in this manual. Report any part shortages to your distributor. Do not discard carton or packing material until machine is assembled and working properly. Exposed metal areas may have a rust protectant applied. Remove this with a soft rag and solvent such as kerosene. (Do not use gasoline, paint thinner, acetone, etc., as these will damage painted surfaces.)

1. Loosen setback locking screws (5).

2. Rotate setback knobs (6) in equal amounts

(clockwise decreases distance). Note: When increasing distance (counter-

clockwise), you may have to pull back slightly on the bending leaf to take up any backlash.

7.3 Assembly

8mm hex key required for assembly.

Numbers in parentheses refer to items in Figure 1.

1. Remove any straps securing the machine, and raise into position using properly rated lifting equipment. The floor must be stable and level.

Continue to stabilize the

machine while installing the support legs.

2. Attach the two support legs (11) with two screws each.

3. Secure machine to floor using lag screws or similar system. See diagram, Figure 2.

8.0 Operation

Numbers in parentheses refer to items in Figure 1.

8.1 Adjusting setback

The bending leaf blade (7) must be adjusted for proper clearance, or “setback” (A, Figure 3) ba sed on material thickness (B, Figure 3). Generally, setback for material within four ga uges of capacity should be twice the thickness of material. For lighter gauges, use 1-1/2 times the material thickness. Consult a machinery handbook for bend allowances.

3. Bring the clamping leaf into position and check the setback.

4. Repeat above steps until proper distance is achieved. Verify that bending leaf blade (7) is parallel to clamping fingers (2).

5. Tighten screws (5).

If a crown develops in the material, this can be adjusted out by loosening or tightening the hex nuts on the crown adjustment rod (12). Note: This rod has been correctly set by the manufacturer and should only be adjusted when needed.

8.2 Adjusting clamping pressure

Clamping pressure should be great enough to hold material securely, but not so much that it becomes difficult to clamp Rotate clamping adjustment knobs (3) equally to set clamping pressure.

8.3 Repeat bends

Adjust stop bolt (4) to limit swing of bending leaf.



7

8.4 General procedure

1. Remove or add clamping fingers as needed for width of material and type of bend.

2. Adjust for setback and clamping pressure.

3. Position stop bolt if needed.

4. Align material in machine and press foot pedal until it locks.

5. Raise bending leaf to desired angle.

6. Lower bending leaf and press foot pedal lock to release material.

9.0 Maintenance

Daily wipe down machine with a soft rag. Apply a light coat of SAE 30 oil to exposed metal surfaces to prevent rust. Daily insert grease into the two fittings (14).

10.0 Troubleshooting

Trouble Probable Cause Remed

Bends created with great dif f iculty.

Clamping leaf will not cl amp prop erly.

Bend radius not consistent across material.

Machine c apacity exceeded. Use material within ca pacity . Incorrect setback. Increase setback.

Improper adjustment. Clamping not even across width. Rotate adjustment knobs equal amount.

Machine c apacity exceeded. Use material within ca pacity . Bending leaf edge not parallel to fingers. Bending leaf has crown. Correct with crown adjustment rod.

Table 1

Decrease distance between fingers and beam.

djust bending leaf equally on both ends.
