Page 26 Power Equipment Usage Manual (Rev. 5/10)

• Cutting across the grain is crosscutting. Never use a fence or fence system for cross-cutting.

Instead, use a miter gauge.

u. BEFORE YOU LEAVE:

• Shut off power, lower blade below table, and clean the saw before you leave it.

• Verify all guards are in place, or reinstall guards.

7.2. Avoiding Kickback! – Table Saw (READ THIS SECTION!)

Kickbacks happen when the saw blade catches the workpiece and violently

throws it back toward the operator causing serious injury to the operator or

someone nearby. A kickback can be fatal. NEVER stand beside or walk behind

anyone using a table saw.

7.2.1. Table Saw Guard

The Woodshop’s rule is to use the blade guard whenever possible. The blade guard incorporates a

spreader called a riving knife, which helps prevent the cut from closing on the back of the saw blade. It

also has an integrated anti-kickback device that allows only forward travel past the blade.

7.2.2. Don’t Be Afraid to Ask

Always ask for help from the Shop Monitor or another woodworker if you need assistance or if you are

unsure of what you are doing.

7.2.3. Kickback when RIPPING or CROSSCUTTING

a) Internal stress in wood can cause the cut to close, pinching the saw blade. Use the blade guard

whenever possible.

b) Always maintain control. Do not execute a cut where you do not have complete control of the

situation.

• Do not allow the wood to rise up or move sideways during a cut. Hold the board firmly

against the fence and down flat on the table until the workpiece is past the blade. You

can also use feather boards very close to the start of the blade and feather board hold

downs after the blade to control the wood all the way through the cut.

• Do not release a workpiece until it is past the blade!

• NEVER lift your hand to reposition it during a cut! Make sure you can reach all the way

through the end of the cut without repositioning your hands.

• Make sure there are no obstructions.

• Do not cut a workpiece that is too large to handle. Ask for help with this cut.

• Never freehand-cut a workpiece. Free-handing causes crooked cuts and potential

kickback. Always use the rip fence to guide the workpiece in a straight line when ripping.
