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 machine 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 bench grinder, 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 holds itself harmless from any injury that may result from that use.

6. Always wear protective eye wear when operating machinery. Eye wear shall be impact resistant, protective safety glasses with side shields which comply with ANSI Z87.1 specifications. Use of eye wear which does not comply with ANSI Z87.1 specifications could result in severe injury from breakage of eye protection. (Everyday eyeglasses only have impact resistant lenses; they are NOT safety glasses.) Use the grinder’s eye shields and spark guards. Also use face or dust mask if cutting operation is dusty.

7. Wear proper apparel. Do not wear loose clothing, neckties, rings, bracelets, or other jewelry which may get caught in moving parts. Non-slip footwear is recommended. Wear protective hair covering to contain long hair.

8. Wear protective clothing such as apron or safety shoes, where the grinding activity presents a hazard to the operator.

9. Wear ear protectors (plugs or muffs) if sound exceeds safe levels.

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

11. 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.)

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

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

14. Make certain the machine is properly grounded.

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

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. 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 completion of maintenance.

18. 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.

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

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

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

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

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

24. Keep proper footing and balance at all times so that you do not fall into or lean against the grinding wheel, belt, or other moving parts. Do not overreach or use excessive force to perform any machine operation.

25. Disconnect grinder before servicing and before changing wheel, disc, or belt.

26. Use recommended accessories. The use of improper accessories may cause risk of injury to persons.

27. Turn off the machine before cleaning. Use a brush to remove chips or debris — do not use bare hands.

28. Never leave the grinder running unattended. Turn power off and do not leave machine until wheels come to a complete stop.

29. Remove loose items and unnecessary work pieces from the area before starting the grinder.

30. Don’t use in dangerous environment. Don’t use power tools in damp or wet location, or expose them to rain. Don’t use this grinder in a flammable environment. Keep work area well lighted.

31. Keep work area clean. Cluttered areas and benches invite accidents.

32. Use right tool. Don't force tool or attachment to do a job for which it was not designed.

33. 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. Sect. 6.2, Table 2 shows the correct size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gage. The smaller the gage number, the heavier the cord.

34. Maintain tools with care. Keep tools sharp and clean for best and safest performance. Follow instructions for lubricating and changing accessories.

35. Never stand on tool. Serious injury could occur if the tool is tipped or if the cutting tool is unintentionally contacted.

36. Direction of feed. Feed work into a blade or cutter against the direction of rotation of the blade or cutter only.

37. Do not overtighten wheel nut.

38. Frequently clean grinding dust from around and beneath grinder.

39. Use grinding wheel suitable for speed of grinder.

40. Inspect abrasive wheels for cracks or other forms of damage. Perform a “ring test” to check wheel integrity. Do not use a faulty or damaged wheel.

41. Verify that maximum RPM of abrasive wheel is compatible with speed of grinder. Do not remove the blotter (label) from either side of a grinding wheel.

42. Allow machine to reach full RPM before starting the grinding operation.

43. Do not crowd the work so that the wheel or abrasive disc slows.

44. Tool rest should be adjusted to approximately 1/16” from wheel surface.

45. Do not grind on the side of a wheel; do all work on the grinding face or edge near the tool rest.

46. Do not grind aluminum or magnesium on the grinding wheel, as these may pose a fire/safety hazard.

47. Use only the flanges that are furnished with the grinder.

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.

Chipped or cracked wheels can break up and cause serious damage to the grinder and/or severe injury to the operator. Regularly inspect wheels for damage.

5.3 Tools required for assembly

Cross-point (Phillips) screwdriver 14mm (or adjustable) wrench

The IBGM-8 Grinder with Multitool Attachment requires only the assembly of the left-hand eye shield and tool rest. Additional tools may be needed for fastening the grinder to a workbench or stand. For your safety, do not plug the grinder into a power source until all assembly and adjustments are complete.

Be sure that the bench grinder

is unplugged and the power switch is in the OFF position. Do not plug in the grinder to power until it is inspected for shipping damage and fully assembled. Failure to comply may cause serious injury.

Do not operate this grinder without all guards and shields in place and in working order. Failure to comply may cause serious injury.

Figure 5-1: Carton contents

5.4 Securing the grinder

To prevent the grinder from moving during operation, it should be securely mounted to a work surface or grinder stand. Fasteners for mounting are not included with the grinder.

1. Align the mounting holes on the grinder with predrilled holes in a bench or grinder stand. Figure 4-1 shows hole centers for mounting.

2. Insert M8 (or 5/16”) bolts through the holes and tighten, using washers and nuts.

An optional pedestal stand (not included) is available from JET for your grinder. See sect. 11.0.
