Cutting (Fig. M) Place the wider portion of the saw shoe on that part of the workpiece which is solidly supported, not on the section that will fall off when the cut is made. As an example, Figure M illustrates the RIGHT way to cut off the end of a board. Always clamp work. Don't try to hold short pieces by hand! Remember to support cantilevered and overhanging material. Use caution when sawing material from below. Be sure saw is up to full speed before blade contacts material to be cut. Starting saw with blade against material to be cut or pushed forward into kerf can result in kickback. Push the saw forward at a speed which allows the blade to cut without laboring. Hardness and toughness can vary even in the same piece of material, and knotty or damp sections can put a heavy load on the saw. When this happens, push the saw more slowly, but hard enough to keep working without much decrease in speed. Forcing the saw can cause rough cuts, inaccuracy, kickback, and over-heating of the motor. Should your cut begin to go off the line, don't try to force it back on. Release the trigger 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. Withdraw the saw if you must shift the cut. Forcing a correction inside the cut can stall the saw and lead to kickback. IF SAW STALLS, RELEASE THE TRIGGER SWITCH 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 switch and allow the blade to stop before lifting the saw from the work. As you lift the saw, the spring-tensioned lower blade guard will automatically close under the blade. Remember the blade is exposed until this occurs. Never reach under the work for any reason. When you have to retract the lower blade guard manually (as is necessary for starting pocket cuts), always use the retracting lever. WARNING: When cutting thin strips, be careful to ensure that small cutoff pieces don't hang up on the inside of the lower blade guard. Ripping (Fig. P) Ripping is the process of cutting wider boards into narrower strips - cutting grain lengthwise. Hand guiding is more difficult for this type of sawing and the use of a DeWALT rip fence is recommended. Fig. P Pocket Cutting (Fig. Q) WARNING: Never tie the lower blade guard in a raised position. Never move the saw backwards when pocket English cutting. This may cause the saw to raise up off the work surface, which could cause injury. Fig. Q 12 A pocket cut is one that is made in a floor, wall or other flat surface. 1. Adjust the saw shoe so the blade cuts at desired depth. 2. Tilt the saw forward and rest front of the shoe on material to be cut. 3. Using the lower blade guard retracting lever, retract the lower blade guard to an upward position. Lower the rear of the shoe until the blade teeth almost touch the cutting line. 4. Release the lower blade guard (its contact with the work will keep it in position to open freely as you start the cut). Remove your hand from the lower blade guard retracting lever and firmly grip the auxiliary handle 12 , as shown in Figure Q. Position your body and arm to allow you to resist kickback if it occurs. 5. Make sure blade is not in contact with cutting surface before starting saw. 6. 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. 7. Release the trigger switch and allow the blade to stop completely before withdrawing the blade from the material. 8. When starting each new cut, repeat the above steps. MAINTENANCE WARNING: To reduce the risk of serious personal injury, turn unit off and remove the battery pack before making any adjustments or removing/ installing attachments or accessories. An accidental start-up can cause injury. Cleaning WARNING: Blow dirt and dust out of all air vents with clean, dry air at least once a week. To minimize the risk of eye injury, always wear ANSI Z87.1 approved eye protection when performing this. WARNING: Never use solvents or other harsh chemicals for cleaning the non-metallic parts of the tool. These chemicals may weaken the plastic materials used in these parts. Use a cloth dampened only with water and mild soap. Never let any liquid get inside the tool; never immerse any part of the tool into a liquid. 13
