Release the switch and allow blade to come to a complete stop. Then you can withdraw the saw, sight anew, and start a new cut slightly inside the wrong one. In any event, withdraw the saw if you must shift the cut. Forcing a correction inside the cut can stall the saw and lead to kickback. SUPPORT WORK NEAR CUT Figure 6 DON’T SUPPORT BOARD OR PANEL AWAY FROM THE CUT. Figure 7 IF SAW STALLS, RELEASE THE TRIGGER AND BACK THE SAW UNTIL IT IS LOOSE. BE SURE BLADE IS STRAIGHT IN THE CUT AND CLEAR OF THE CUTTING EDGE BEFORE RESTARTING. As you finish a cut, release the trigger and allow the blade to stop before lifting the saw from the work. As you lift the saw, the spring-tensioned telescoping guard will automatically close under the blade. Remember the blade is exposed until this occurs, never reach under the work for any reason whatsoever. When you have to retract the telescoping guard manually (as is necessary for starting pocket cuts) always use the retracting lever. NOTE: When cutting thin strips, be careful to ensure that small cutoff pieces don’t hang up on inside of of lower guard. CROSS CUTTING Saws are used mostly to cut board to desired lengths- crossgrain cutting. Guide the machine by gripping the top handle with the left hand and sighting along the line thru the blade guide as shown in Figure 9. Move the saw just fast enough to keep the blade cutting. Do not force it and do not twist it sideways. When the blade has completed the cut, release the trigger switch. RIPPING Ripping is the process of cutting wide boards into narrower strips- cutting the grain lengthwise. Hand guiding is a little more difficult for this type of sawing and some type of guide should be used. A rip fence (Figure 10) may be purchased separately for this purpose (Cat# 60551). Insert the rip fence in the slot at the front (either side) of the base and under the clamp screw bracket. Set for desired width of cut by first measuring width on material to be cut then adjusting the rip fence to that width. Before proceeding with the cut, be sure to tighten the clamp screw. Figure 8 POCKET CUTTING A pocket cut is one that is made in a floor, wall or other flat surface. Adjust saw shoe so blade cuts at desired depth. Tilt saw forward and rest front of the shoe on material to be cut. Using the retracting lever, retract blade guard to an upward position. Lower rear of shoe until blade teeth almost touch cutting line. Now release the blade guard (its contact with the work will keep it in position to open freely as you start the cut) Figure 11. Start the motor and gradually lower the saw until its shoe rests flat on the material to be cut. Advance saw along the cutting line until cut is completed. Release trigger and allow blade to stop completely before withdrawing the blade from the material. When starting each new cut, repeat as above. Never tie the blade guard in a raised position. Kickback When the saw blade becomes pinched or twisted in the cut kickback can occur. The saw is thrust rapidly back toward the operator. When the blade is pinched or bound tightly by the kerf closing down, the blade stalls and the motor reaction drives the unit backward. When the blade becomes twisted or misaligned in the cut, the teeth at the back edge of the blade can dig into the top surface of the wood causing the blade to climb out of the kerf and jump back toward the operator. Kickback is more likely to occur when any of the following conditions exist. Improper workpiece support Sagging or improper lifting of the cutoff piece causing pinching of the blade. Cutting through material supported at the outer ends only (Figure 6). As the material weakens it sags, closing down the kerf and pinching the blade. Cutting of a cantilevered or overhanging piece of material from the bottom up in a vertical direction. The falling cut off piece can pinch the blade. Cutting off long narrow strips (as in ripping). The cutoff strip can sag or twist closing the kerf and pinching the blade. Snagging the lower guard on a surface below the material being cut momentarily reducing operator control. The saw can lift partially out of the cut increasing the chance of blade twist. Improper depth of cut setting on saw Using the saw with an excessive depth of cut setting increases loading on the unit and susceptibility to twisting of the blade in the kerf. It also increases the surface area of the blade available for pinching under conditions of kerf close down. Blade twisting (misalignment in cut) Pushing harder to cut through a knot, a nail, or hard grain area can cause blade to twist. % Trying to turn the saw in the cut (trying to get back on the marked line) can cause blade twist. Extended reach or operating saw with poor body control (out of balance) can result in twisting the blade. Changing grip or body position while cutting can result in blade twist. Backing unit up to clear blade can lead to twist if not done carefully. Materials that require ...
