2. Objectives Given a diagram of a band saw, students will be able to identify parts of the machine with complete accuracy. Given the first part of each sentence, students will be able to complete the statement which shows their knowledge of each of the twelve band saw safety rules with complete accuracy.

3. Parts of the Band Saw On/Off Switch Most important part to know Newer band saws will be marked with green and red buttons It should always be found on the same side of the machine that you work on

4. Parts of the Band Saw Brake Some band saws have a foot pedal brake When the machine has been turned off, it stops the blade quicker

5. Parts of the Band Saw Table Work surface Some tables may be adjusted for angled cuts Some tables come with a slot for a miter guage

6. Parts of the Band Saw Miter Guage May have a clamp to fasten your work piece It is adjustable for cuts at desired angles Slides thru a slot on the band saw table Gives more protection to your hands and fingers

7. Parts of the Band Saw Adjustable Fence Used as a guide for making straight cuts If the table is angled, it should always be used, except when the work piece is clamped to a miter guage Is adjustable to achieve desired distance from the blade

8. Parts of the Band Saw Blade Always travels in the downward direction to keep from throwing a work piece away from the table It is welded together in one piece and travels taught around two wheels

9. Parts of the Band Saw Blade Tension Adjustment It is a wheel used to adjust tension on the blade Keeps the blade from coming off of the wheel Keeps the blade straight and secure

10. Parts of the Band Saw Blade Guard Keeps the blade enclosed If the blade were to break it keeps the blade from potentially whipping free of the machine If you were to bend over the work piece, it would protect your head and hair from injury

11. Parts of the Band Saw Upper Guide Assembly It is made up of a couple wheel bearings that come together on both sides of the blade Keeps the blade in line with your cuts Keeps the blade from shaking

12. Parts of the Band Saw Adjustment for Upper Guide Assembly Raises and lowers the upper guard assembly to a height that allows your work piece to enter the blade

13. Parts of the Band Saw Upper Wheel Guard Door Similar to the blade guard, it keeps the blade and wheel from being exposed while running Allows access to the upper wheel for cleaning and maintenance Small wood chips and saw dust may fill up the inside after use

14. Parts of the Band Saw Lower Wheel Guard Door Similar to the blade guard, it keeps the blade and wheel from being exposed while running Allows access to the upper wheel for cleaning and maintenance Small wood chips and saw dust may fill up the inside after use

15. Parts of the Band Saw Lower Wheel Guard Door Similar to the blade guard, it keeps the blade and wheel from being exposed while running Allows access to the upper wheel for cleaning and maintenance Small wood chips and saw dust may fill up the inside after use

16. Band Saw Safety Rules Wheel guard doors must be closed and the blade properly adjusted before turning on the machine. Adjust the upper guide assembly so that it is � in. above the work. Allow the saw to reach full speed before starting to feed your work piece. The work piece must be held flat on the table. Feed the saw blade only as fast as the teeth will remove the wood easily. Keep hands and fingers away from the blade by 2 in.

17. Band Saw Safety Rules (cont.) Plan saw cuts to avoid backing out of curves whenever possible. Avoid twisting the blade by making small turns in the work piece. Before backing out of a long curved cut turn off the machine and wait for the blade to stop while keeping one hand on the work piece. Round stock (dowels) should not be cut unless mounted securely in a jig or miter guage. If you hear a clicking sound turn the machine off immediately and notify your instructor that the blade may be cracked. Do not leave your machine until it has been turned off and has come to a complete stop.
