3.0 Safety warnings

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 the warning labels if they become obscured or removed.

4. This table saw 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 table saw, do not use until proper training and knowledge have been obtained.

5. Do not use this table saw 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 approved safety glasses/face shield while using this table saw. Everyday eyeglasses only have impact resistant lenses; they are not safety glasses.

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

8. Use the blade guard for every operation for which it can be used, including all ''throughsawing'' operations. A through-sawing operation is one in which the blade cuts completely through the workpiece.

9. Kick back occurs when the workpiece is thrown towards the operator at a high rate of speed. If you do not have a clear understanding of kickback and how it occurs, DO NOT operate this table saw!

10. Wear ear protectors (plugs or muffs) during extended periods of operation.

11. WARNING: Drilling, sawing, sanding or machining wood products generates wood dust and other substances known to the State of California to cause cancer. Avoid inhaling dust generated from wood products or use a dust mask or other safeguards to avoid inhaling dust generated from wood products.

12. Wood products emit chemicals known to the State of California to cause birth defects or other reproductive harm. (California Health and Safety Code Section 25249.6)

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

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

15. Make certain the machine is properly grounded.

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

17. 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.

18. 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.

19. 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.

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

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

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

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

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

25. Maintain a balanced stance at all times so that you do not fall into the blade or other moving parts. Do not overreach or use excessive force to perform any machine operation.

26. 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.

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

28. Maintain tools with care. Keep saw blades sharp and clean for the best and safest performance. Follow instructions for lubricating and changing accessories.

29. Turn off the machine before cleaning. Use a brush or compressed air to remove chips or debris — do not use your hands.

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

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

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 injury or possibly even

death.

32. Remove loose items and unnecessary work pieces from the area before starting the machine.

33. Keep hands out of the line of saw blade.

34. Use a push-stick when required.

35. Pay particular attention to instructions on reducing risk of kickback.

36. Do not perform any operation freehand.

37. Never reach around or over saw blade.

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

5.0 Glossary

Arbor: Metal shaft that connects the drive mechanism to the blade.

Bevel Edge Cut: Tilt of the saw arbor and blade between 0° and 45° to perform an angled cutting operation.

Blade Guard: Mechanism mounted over the saw blade to prevent accidental contact with the cutting edge.

Crosscut: Sawing operation in which the miter gauge is used to cut across the grain of the workpiece.

Dado Blade: Blade(s) used for cutting grooves and rabbets. A stacked dado set can be used for wider grooves.

Dado Cut: Flat bottomed groove in the face of the workpiece made with a dado blade.

Featherboard: Device used to keep a board against the rip fence or table that allows the operator to keep hands away from saw blade.

Freehand: Moving the workpiece into the blade using only the hands, without a fixed positioning device. (This is a dangerous, unacceptable procedure – always use appropriate devices to feed the workpiece though the saw blade during cutting operations.)

Kerf: The resulting cut or gap made by a saw blade.

Kickback: An event in which the workpiece is lifted up and thrown back toward an operator, caused when a workpiece binds on the saw blade or between the blade and rip fence (or other fixed object). To minimize or prevent injury from kickbacks, see the Operations section.

Miter Gauge: A component that controls the workpiece movement while performing a crosscut of various angles.

Non-Through Cut: A sawing operation that requires the removal of the blade guard and standard riving knife, resulting in a cut that does not protrude through the top of the workpiece (includes Dado and rabbet cuts).

The blade guard and riving knife must be reinstalled after performing a non-through cut to avoid accidental contact with the saw blade during operation.

Parallel: Position of the rip fence equal in distance at every point to the side face of the saw blade.

Perpendicular: 90° (right angle) intersection or position of the vertical and horizontal planes such as the position of the saw blade (vertical) to the table surface (horizontal).

Push Board/Push Stick: An instrument used to safely push the workpiece through the cutting operation.

Rabbet: A cutting operation that creates an L-shaped channel along the edge of a board.

Rip Cut: A cut made along the grain of the workpiece.

Riving Knife: A metal plate fixed relative to the blade, which moves with the blade as cutting depth is adjusted. Thus, it maintains not only the kerf opening in the workpiece, but also the knife-toblade distance. A low-profile riving knife is used when performing a non-through cut because it si ts lower than the top edge of the blade.

Splitter (Spreader): A stationary metal plate to which the blade guard is attached that maintains the kerf opening in the workpiece when performing a cutting operation.

Standard Kerf: 1/8" gap made with a standard blade.

Straightedge: A tool used to check that a surface is flat or parallel.

Through Sawing: A sawing operation in which the workpiece thickness is completely sawn through. Proper blade height usually allows 1/8" of the top of blade to extend above the wood stock. Keep the blade guard down, the anti-kickback pawls down, and the riving knife in place over the blade.
