OPERATION STRAIGHT CUT See Figures 7, page 13. A straight cut can be made by clamping a piece of wood or straight-edge to the workpiece and guiding the edge of the saw against it. Make the cut from one direction only. Don't cut halfway and complete the cut from the opposite end. WARNING: To avoid possible serious injury, keep hands and fingers from between the gear housing and saw blade clamp, and keep the guard in place. WARNING: Excessive side pressure to the blade could result in broken blades or damage to the material being cut. ANGLE CUTTING (BEVEL CUTTING) See Figure 8, page 13. Bevel cutting angles may be adjusted from 0° to 45° right or left. Angles for cuts from 0° to 45° in 15° increments are marked on a scale on both the left and right side of the base. An arrow under the motor assembly provides an indicator at each of the above mentioned 15° increments. A protractor is recommended when accurate cuts are required. Unplug the saw. Unlock the base by moving the base adjustment lever forward. Slide the base forward to release it from the 0º detent position. Align the mark of the desired angle with the indicator arrow located on the housing. NOTE: For a 0º cut, slide the base back until it locks into the 0º detent position. Once the desired angle is reached, tighten the base adjustment lever by moving it back under the motor assembly. SCROLL CUTTING See Figure 9, page 13. Scroll cuts can be made with the jig saw by guiding the direction of the cut with applied pressure on the handle as shown. NOTE: Tighter tolerance scroll cutting may require the use of a scroll cutting blade (not included). WARNING: Excessive side pressure to the blade could result in broken blades or damage to the material being cut. PLUNGE CUTTING See Figure 10, page 13. NOTE: Use only a 7-teeth-per-inch blade for this type of cut. WARNING: To avoid loss of control, broken blades, or damage to the material being cut, always use extreme caution when making plunge cuts. We do not recommend plunge cutting on materials other than wood. Mark the line of cut clearly on the workpiece. Set the orbit adjustment to "0". Set the cutting angle at 0°. Tilt the saw forward so that it rests on the front edge of the base and blade will not come in contact with the workpiece when the saw is turned on. Make sure the blade is inside the area to be cut. Using high speed, start the saw and slowly lower the blade into the workpiece until the blade cuts through the wood. Continue lowering the blade into the workpiece until the base rests flat on the work surface, then move the saw forward to complete the opening. METAL CUTTING See Figure 11, page 13. NOTE: The jig saw has to be in the no-orbit mode to cut metals and conduit. Set the orbital adjustment knob to "0." Refer to the Orbital Motion section earlier in this manual for more details. Many kinds of metals can be cut with the saw using a metal blade (not included). Be careful not to twist or bend the blades. Do not force. If the blade chatters or vibrates excessively, use a finer-tooth metal-cutting blade. If blade heats excessively, use lower speed. If blade teeth become filled or clogged when cutting soft metals, such as aluminum, use a coarser-tooth blade or lower speed. We recommend use of lubricant when cutting metals to keep blades cool, increase cutting action, and prolong blade life. Clamp the work firmly and saw close to the clamping point to eliminate any vibration of the work being cut. When cutting conduit, pipe, or angle iron, clamp work in a vise if possible and saw close to the vise. To cut thin sheet materials, "sandwich" the material between hardboard or plywood and clamp the layers to eliminate vibration and material tearing. By doing this, the material will be cut smoothly. Lay out your pattern or line of cut on top of the "sandwich." NOTE: When cutting metal, keep exposed portion of saw bar clean and free of metal chips by wiping frequently with an oily cloth. Use extreme caution in disposing of oily cloth after completion of job to prevent potential fire hazard. 8 - English
