OPERATION

RIP CUT HAZARDS AND PRECAUTIONS

Two hazards are specifically associated with rip

cutting: outfeed zone and wrong way feed.

In the outfeed zone (behind the blade), the blade

teeth point down. The slightest contact while the blade

is still spinning can snag clothing, jewelry, the work

piece, or even skin, causing serious personal injury.

Wrong way feed occurs when the workpiece contacts

the blade from the outfeed side. It is very hazardous

and will jerk the workpiece violently. You could be cut

if you are holding the workpiece.

A WARNING: Failure to observe any of these

precautions can result in serious Injury.

■ The first precaution is, of course, simply to stay

completely away from the outfeed zone. Keep

hands away from the outfeed zone.

■ Point the anti-kickback pawls away from the blade

teeth to snag a workpiece If the blade grabs. They

should be positioned to rest lightly on the

workpiece. The flat side of the pawls should be

level and horizontal.

■ Set the riving knife to just clear the table.

■ Set the hold down in front of the biade to just ciear

the workpiece.

■ Start and finish your cut from the infeed side.

■ Push the workpiece past the pawls with push

blocks and pushsticks to finish the cut.

■ If the blade jams, turn the saw off with the switch

on the arm, remove the yellow key, and wait for the

blade to fully stop before freeing It.

■ Make sure the blade Is parallel to the fence and the

workpiece is not warped or twisted.

■ Make sure no pressure is applied to the workpiece

on the outfeed side.

■ Make sure the blade guard is lowered and is

working properly.

■ Always set up the workpiece so the wider part of

the wood is between the blade and the fence. This

stabilizes the workpiece better.

■ Do not release the workpiece until it has moved

past the pawls. Keep pushsticks firmly in place.

■ Use pushsticks and pushblocks, not your hands,

when the trailing edge of the workpiece is within

3 In. of the blade. If the blade is set 2 in. or more

from the fence, use a pushstick. Use a pushblock

and auxiliary fence when the blade Is between 2 in.

and 1/2 in. from the fence. (If the cut is narrower

than 1/2 in., use a different saw.) For large panel

rip cuts, use a featherboard instead of pushblocks

or pushsticks. See the section on Cutting Aids.

A precise and safe rip cut requires a careful set up.

Before setting up for in-rIp or out-rIp, especially for a

bevel cut, try the workpiece in both placements.

Check for stability, visibility, and control. Test which

will give the best pushstick clearance.

Instructions are given for an in-rip cut. At certain

points, the instructions will vary for a bevel rip cut or

an out-rip process and will be enclosed in parenthe

ses (example). Figure 47 shows an out-rip setup.

■ Insert a solid fence with no kerfs. Use an auxiliary

fence if the blade will be set only 1/2 in. to 2 in.

from the fence. Tighten the table clamps.

■ If the arm is too low or too high, first lift the blade

guard if the arm is too low, and turn the elevating

handwheel at the front of the table. Set the blade to

just clear the kerf or table.

■ Change the blade angle if needed. Raise the plastic

lower guard to keep It from jamming, release the

bevel lock lever, and set the bevel indicator to zero.

(For a bevel rip cut, set the bevel Indicator to

the desired angle.) Test the clearance on the

guard. Retighten the bevel lock lever.
