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 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.

5. Do not use this band saw for other than its intended use. If used for other purposes, JPW (TOOLS) Inc., 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 shields while using this band saw. Everyday eyeglasses only have impact

resistant lenses; they are not safety glasses.

7. Before operating this band 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. Wear ear protectors (plugs or muffs) during extended periods of operation.

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.

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 well-ventilated area and work with approved safety 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 the switch is in the OFF position before connecting the machine to the power supply.

12. Make certain the machine is properly grounded.

13. Make all machine adjustments or maintenance with the 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 the machine is in use. If removed for maintenance purposes, use

extreme caution and replace the guards immediately.

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 and perform its intended function. Check for alignment of

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

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

21. Give your work undivided attention. Looking around, carrying on a conversation and “horse-play” are careless acts

that can result in serious injury.

22. Maintain a balanced stance at all times so that you do not fall or lean against 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 safer.

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

25. Maintain tools with care. Keep blades sharp and clean for the best and safest performance. Follow instructions for

lubricating and changing accessories.

26. Make sure the work piece is securely clamped in the vise. Never use your hand to hold the work piece.

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 the blade

comes to a complete stop.

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

31. Pull the mains plug if the machine is not in use.

manual before attempting assembly or

operation! Failure to comply may cause serious

injury.

Unpacking

Remove box and wood crating completely from

around saw. Check for shipping damage. Report

any damage immediately to your distributor and

shipping agent. Do not discard any shipping

material until the Table Saw is assembled and

running properly.

Compare the contents of your container with the

parts lists in the next page to make sure all parts

are intact. Missing parts, if any, should be reported

to your distributor. Read the instruction manual

thoroughly for assembly, maintenance and safety

instructions.

lighting. Leave enough space around the machine

for mounting extension trays and bow swivel, and

loading and off-loading stock and general

maintenance work.

Cleaning

Exposed metal surfaces, such as the table top and

moveable vise sliding area, have been given a

protective coating at the factory. This should be

removed with a soft cloth moistened with

kerosene. Do not use acetone, gasoline, or lacquer

thinner for this purpose. Do not use solvents on

plastic parts, and do not use an abrasive pad

because it may scratch the surfaces.

Prior to operation

1. Check to see blade tooth direction matches

diagram on saw body.
