1.0 IMPORTANT SAFETY

INSTRUCTIONS

Read and understand the entire instruction manual before operating machine.

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

WARNING – To reduce risk of injury:

a. Wear eye protection. b. Do not remove jammed cut off pieces until

blade has stopped.

c. Maintain proper adjustment of blade

tension, blade guides, and thrust bearing. d. Adjust upper guide to just clear workpiece. e. Secure workpiece firmly against table.

1. 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.

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

3. Do not use this band 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.

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

5. Before operating this machine, 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 recommended. Do not wear gloves.

6. Wear hearing protection (plugs or muffs) during extended periods of operation.

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

8. Reduce the risk of unintentional starting. Make sure switch is in off position before plugging in.

9. Make certain the machine is properly grounded.

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

11. 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.

12. 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.

13. 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.

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

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

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

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

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

19. 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.

20. 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.

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

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

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

24. Do not stand on the machine. Serious injury could occur if the machine tips over, or if the cutting tool is unintentionally contacted.

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

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

27. Make sure workpiece is securely clamped in vise. Never use your hand to hold the workpiece.

28. Never reach around or over a moving saw blade.

29. Feed work into a blade or cutter only against the direction of rotation of the blade or cutter.

30. Set blade guides for minimal exposure of blade before operating.

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. 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. 6.3) 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.

WARNING: This product can expose you to chemicals including lead which is known to the State of California to cause cancer and birth defects or other reproductive harm, and ethylbenzene which is known to the State of California to cause cancer. For more information go to http://www.p65warnings.ca.gov.

WARNING: Some dust, fumes and gases created by power sanding, sawing, grinding, drilling, welding and other construction activities contain chemicals known to the State of California to cause cancer and 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 wellventilated area and work with approved safety equipment, such as dust masks that are specifically designed to filter out microscopic particles.

6.0 Electrical connections

The HVBS-56 Band Saw is rated at 115/230V power, and is pre-wired for 115 volt. The band saw comes with a plug designed for use on a circuit with a grounded outlet that looks like the one pictured in A, Figure 8.

Before connecting to power source, be sure switch is in off position.

It is recommended that the band saw be connected to a dedicated 15 amp circuit with circuit breaker or fuse. If connected to a circuit protected by fuses, use time delay fuse marked “D”. Local codes take precedence over recommendations.

6.1 GROUNDING INSTRUCTIONS

This machine must be grounded. In the event of a malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This tool is equipped with an electric cord having an equipment-grounding conductor and a grounding plug. The plug must be plugged into a matching outlet that is properly installed and grounded in accordance with all local codes and ordinances.

Do not modify the plug provided - if it will not fit the outlet, have the proper outlet installed by a qualified electrician.

Improper connection of the equipment-grounding conductor can result in a risk of electric shock. The conductor with insulation having an outer surface that is green with or without yellow stripes is the equipment-grounding conductor. If repair or replacement of the electric cord or plug is necessary, do not connect the equipment-grounding conductor to a live terminal.
