Machining Fundamentals

• Get help when you are lifting and cutting
heavy material.
• Clean oil, grease, and coolant from the floor
around the work area.
• Burrs on cut pieces are sharp. Use special care
when handling pieces with burrs.
• Follow the manufacturer’s instructions for
tensioning a blade. Too much tension can
shatter the blade.
• Handle band saw blades with extreme care.
They are long and springy and can uncoil
suddenly.
• Be sure the work is mounted solidly before
starting a cut.
• Be sure all guards are in place before using
the saw.
• Always wear a dust mask and full face shield
when cutting stock with a dry-type abrasive
cutoff saw.
• Avoid standing directly in line with the blade
when operating a circular cutoff saw.
• Use a brush to clean chips from the machine.
Do not use your hands. Wait for the machine
to come to a complete stop before cleaning.
• Keep your hands out of the way of moving
parts.
• Stop the machine before making adjustments.
• Have all cuts, bruises, and scratches, even
minor ones, treated immediately.
