Operation

Your table saw can be used to make a variety of cuts including longitudinal cuts, bevel cuts and mitre cross cuts. The below section defines a common list of table saw terms:

Through Sawing. Any cutting operation where the blade extends completely through the thickness of the workpiece.

Non-Through Sawing. Any cutting operation where the blade does not extend through the workpiece.

Rip Cut. A cutting or shaping operation made along the length or grain of the workpiece.

Cross Cut. A cut or shaping operation made across the width of the workpiece cutting the workpiece to length.

Freehand. Performing a cut without a fence, mitre gauge, fixture, hold down or other proper device to keep the workpiece from twisting during the cut.

Kickback. An uncontrolled grabbing and throwing of the workpiece back toward the front of the saw.

Anti-Kickback Pawls. A device, which when properly maintained is designed to stop the workpiece from being kicked back at the operator during operation.

Riving Knife. Also known as a separator or spreader. The riving knife is a metal piece slightly thinner than the saw

Push Block. A device used for ripping-type operations too narrow to allow use of a push stick.

Push sticks

A push stick should always be used if your hand gets within 125mm (5”) of the saw blade. A push stick is a safety device that helps to keep your hands and fingers

away from the saw blade. A handle helps to apply pressure to the workpiece whilst a notch at the front of the push stick fits onto the edge of the wood to help push it through the saw. A push stick can be easily made from a scrap piece of material. The push stick must be narrower than the workpiece. Please refer to the diagram which depicts a push stick.

Kickback

Kickback occurs when the blade stalls or binds, kicking the workpiece back towards the front of the saw. Kickback can cause serious injury. Precautions must be taken to avoid kickback. The following conditions can cause kickback and should be avoided.

•Making a cut with the incorrect blade depth

•Attempting to saw through knots or nails in the workpiece

•Twisting the wood while making a cut

•Failing to correctly position the riving knife

•Making a cut with a dull, gummed-up or improperly set blade.
