3.0 Safety warnings

Wear eye protection.

Always keep guards i n place and in proper

operating condition.

This sander is intended to be used with wood and

wood products only. Use of this sander and a

dust collector with metal products is a potential

fire hazard.

Support the workpiece adequately at all times

during operation; maintain control of the work at

all times.

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 warning s may cause serious injury.

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

4. This spindle sander is designed and intended for use by properly trained and experienced perso nnel on ly. If you are no t fam iliar w ith the proper and safe operation of a spindle sander, do not use until proper training and knowledge have been obtained.

5. Do not use this sander for other than its intended use. If used for other purposes, JET disclaims any real or implied warranty and holds itself harm less from any inj ury t hat m ay res ult from that use.

6. Always wear approved safety glasses/face shields while using this spindle sander. Everyday eyeglasses only have impact resistant lenses; they a re not safety glasses.

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

• 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 w ork. To red uce your exposure to these chemicals, work in a wellventilated area and work with approved saf ety 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. Make certain switch is in OFF position before connecting machine to power supply.

12. Make certain machine is properly grounded.

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

14. 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.

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

16. 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 a nd 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.

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

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

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

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

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

• Lead from lead based paint.

20. Make your workshop child proof w ith padlocks, master switches or by removing starter keys.

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

22. 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.

23. 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.

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

25. Maintain tools with care. Follow instruct ions for lubricating and changing accessories.

26. 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 2 (see sect. 7.3) shows 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.

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

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

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

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

31. 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.

32. Hold workpiece down against table firmly at all times.

33. Do not sand workpieces that are too small to be safely supported.

34. Always use appropriate table insert for the selected spindle or drum. Do not san d wi thout a table insert in place.

35. Allow machine to reach operating speed before beginning to sand.

36. Do not operate this sander with a damaged spindle or sanding sleeve.

37. Always feed wo rk against d irectio n of spi ndle rotation.

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

This means that if preca utions are not heeded, it m ay result in minor injury a nd/or possible

machine damage.

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

injury.
