BAND SAW

Function:

The function of a band saw is to cut various materials (i.e.: wood, aluminum, steel, plastics,etc.) into different shapes and curves. Its proper use is essential in order to avoid injury.

Proper Use:

The band saw is a very versatile piece of shop equipment requiring your full attention during itsoperation. Always ensure that the piece being cut is being feed with both hands parallel to thecutting blade but never directly in front of the saw blade. This practice will ensure that aninadvertent slip will not bring your fingers into contact with the cutting blade. A slight downwardforce of the piece against the table will also keep the piece being cut from vibrating on the table.

Most band saws are equipped with a tilting table enabling angled cuts. Some band saws arealso equipped with speed control. Band saw blades come in a variety of sizes and cutting toothpatterns. Smaller thinner blades permit cutting a smaller diameter radius, but they also tend totrack and wander more. The hook on the cutting teeth should always be pointing down towardsthe table. If not, do not attempt to use the equipment because the blade has been installedbackwards.




Use appropriate cutting blade for the material being cut. Ascertain the correct cutting speed for the material being cut. (if band saw has speed

control)

Make sure the tilting table bed friction lock is secure.


Make sure all safety guards and covers are in place. Position the cutting height adjustment guard as close to the material height as practical.

Ascertain correct tension and centering of the blade on the drive and tensioning wheels.

A dust mask may be required for certain types of materials (consult MSDS sheets)

Do not exert excessive force when cutting; let the blade do the work. Use cutting fluid if required and avoid heat build-up.
