WARNING

1.

Read and understand the entire instruction manual before attempting assembly or operation.

2.

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 bandsaw, do
not use until proper training and knowledge have been obtained.

3.

Always wear approved safety glasses/face shields while using this machine.

4.

Make certain the machine is properly grounded.

5.

Before operating the machine, remove tie, rings, watches, other jewelry, and roll up sleeves above
the elbow. Remove all loose clothing and confine long hair. Do not wear gloves.

6.

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

7.

Keep the machine 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.

8.

Do not over reach. Maintain a balanced stance at all times so that you do not fall or lean against
blades or other moving parts.

9.

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

10. Use the right tool. Don’t force a tool or attachment to do a job which it was not designed for.

11. Replace warning labels if they become obscured or removed.

12. Make certain the bandsaw power switch is in the off position before connecting the machine to the

power supply.

13. Give your work undivided attention. Looking around, carrying on a conversation, and “horse-play”

are careless acts that can result in serious injury.

14. Keep visitors a safe distance from the work area.

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

16. Adjust and position upper and lower blade guides before starting to cut. Upper blade guide should be

adjusted to approximately 1/8” above the material to be cut.

17. Adjust blade tension and tracking before starting to cut.

18. Always keep hands and fingers away from the blade when the machine is running.

19. Stop the machine and wait for the blade to stop moving before removing scrap material from the

table.

20. Use suitable support if stock does not have a flat surface.

21. Hold material firmly against the table.

22. Saw teeth must point down toward the table.

23. Some dust created by power sanding, sawing, grinding, drilling and other construction activities

contains 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 and cement and other masonry products, and

• 

arsenic and chromium from chemically-treated lumber.

24. Your risk from those exposures 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 those dust masks that are specifically designed to filter out microscopic particles.

25. Do not operate tool while under the influence of drugs, alcohol or any medication.

26. Failure to comply with all of these warnings may cause serious injury.
