1.0 IMPORTANT SAFETY

INSTRUCTIONS

WARNING – To reduce risk of injury:

1. Read and understand the 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 electric pinch roll bender is designed and intended for use by properly trained and experienced personnel only. If you are not familiar with the proper and safe operation of a pinch roll bender, do not use it 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 holds itself harmless from any injury that may result from that use.

6. Always wear ANSI Z87.1 approved safety glasses or face shield while using this machine. (Everyday eyeglasses only have impact resistant lenses; they are not safety glasses.)

7. Wear ear protectors (plugs or muffs) if noise exceeds safe levels.

8. Make certain the machine is properly grounded.

9. Before operating the machine, remove tie, rings, watches, other jewelry, and roll sleeves up past the elbows. Do not wear loose clothing. Confine long hair.

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

11. Keep machine guards in place at all tim es when the machine is in use. If removed for maintenance purposes, use extreme caution and replace the guards immediately upon completion of maintenance.

12. Check damaged parts. Before further use of the machine, a guard or other part that is damaged should be carefully checked to determine that it will operate properly and perform its intended function. Check for alignment of moving parts, binding of moving parts, breakage of parts, mounting and any other conditions that may affect its operation. A guard or other part that is

damaged should be properly repaired or replaced.

13. Make all machine adjustments or maintenance with machine unplugged from power source.

14. Use the right tool. Do not force a tool or attachment to do a job that it was not designed to do.

15. Make certain the switch is in the OFF position before connecting the machine to the power supply.

16. Remove adjusting keys and wrenches. Form a habit of checking to see that keys and adjusting wrenches are removed from the machine before turning it on.

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

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

19. Make your workshop child proof with padlocks, master switches or by removing starter keys.

20. Do not overreach. Failure to maintain proper working position can cause you to fall into the machine or allow clothing to get caught, pulling you into the machine.

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

22. Use recommended accessories; improper accessories may be hazardous.

23. CALIFORNIA PROPOSITION 65 WARNING: This product contains chemicals known to the State of California to cause cancer, or birth defects or other reproductive harm.

24. This product, when used for welding, cutting, or working with metal, produces fumes, gases, or dusts which contain chemicals known to the State of California to cause birth defects and, in some cases, cancer. (California Health and Safety Code Section 25249.5 et seq.)

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

26. Keep tools sharp and clean for safe and best performance.

27. Deburr any sharp metal edges of the workpiece before placing it into the machine.

28. Keep hands away from pinch roll area during operation.

29. Do not attempt to feed material beyond the maximum capacity of machine. See Table 3.

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

31. Don't use in dangerous environment. Don't use power tools in damp or wet locations, or expose them to rain.

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

33. Never leave the machine running unattended. Turn the power off and do not leave the machine until it comes to a complete stop.

34. Use only JET factory authorized replacement parts and accessories; otherwise, the warranty and guarantee are null and void.

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

This means that if precautions are not heeded, it may result in minor injury and/or possible

machine damage.

This means that if precautions are not heeded, it may result in serious, or possibly even fatal,

injury.

35. Use proper extension cord. Make sure your extension cord is in good condition. When using an extension cord, be sure to use one heavy enough to carry the current your product will draw. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. Table 1 (sect. 6.2) shows correct size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.

5.2 Positioning and cleanup

Position machine so there is enough room on all sides for general maintenance and feeding of materials. Anchor machine to a stable floor, preferably concrete, using lag screws or other appropriate fasteners through the holes in base. Level the machine; use shims if needed.

Exposed metal surfaces have been given a protective coating. Remove this with a soft cloth and a cleaner-degreaser. Do not use gasoline, paint thinner, acetone, etc., as these may damage painted surfaces. Do not use an abrasive pad, as it may scratch polished surfaces.

This machine may be used in vertical or horizontal position (Figure 5-2).

Figure 5-2

For horizontal position:

Remove any fasteners holding machine to pallet, and use a forklift or hoist with straps to carefully move machine into position. Place straps around handle, as shown in Figure 5-1. Lifting equipment

must be properly rated for weight of machine.

Figure 5-1

Machine must be anchored

to floor. Failure to comply may cause serious injury.

1. Open cabinet door and remove two socket head cap screws (Figure 5-3).

2. Carefully move head to horizontal position, and insert the two socket head cap screws into the back holes, as shown. Securely tighten screws.
