DW 897-220 5/2/02 1:48 PM Page 2 English • CHECK DAMAGED PARTS. Before further use of the tool, a guard or other part that is damaged should be carefully checked to determine that it will operate properly and perform its intended function. Check for alignment of moving parts, binding of moving parts, breakage of parts, mounting, and any other conditions that may affect its operation. A guard or other part that is defective should be properly repaired or replaced by an authorized service center unless otherwise indicated elsewhere in this instruction manual. Have defective switches replaced by authorized service center. Do not use tool if switch does not turn it on and off. • DO NOT OPERATE portable electric tools near flammable liquids or in gaseous or explosive atmospheres. Motors in these tools normally spark, and the sparks might ignite fumes. • CAUTION: When drilling or driving into walls, floors or wherever live electrical wires may be encountered, DO NOT TOUCH ANY METAL PARTS OF THE TOOLS! Hold the tool only by insulated grasping surfaces to prevent electric shock if you drive into a live wire. SAVE THESE INSTRUCTIONS FOR FUTURE USE Operating Rules for Nibblers 1. Always wear safety glasses and protective gloves. 2. Wear safety shoes to protect your feet from sharp metal debris on floor. 3. Cut material at or below rated capacity. Remember, material thickness increases as gauge number decreases (14 gauge is thicker than 16 gauge). 14 gauge thickness is .075" (1,9 mm); 16 gauge is .060" (1,5 mm). 4. Keep all screws tight. Periodically check them for loosening. 5. Unplug tool before making any adjustments. 6. Do not put anything into a motor housing opening. 7. Keep tool clean. Blow off any metal debris and dirt from tool. 8. Firmly secure the piece of metal to be cut to prevent movement during cutting. PADDLE SWITCH To start the tool, depress the paddle switch. To turn the tool off, release the paddle. The switch can be locked on be engaging the lock button located near the rear of the tool while holding the paddle depressed. Always be sure that the tool is not locked on before plugging it in. To turn the tool off when it is locked on, squeeze and release the paddle once. Operation TURN OFF TOOL AND DISCONNECT FROM POWER SUPPLY BEFORE MAKING ANY ADJUSTMENTS. Always wear safety glasses and protective gloves. Lubricate surface of material with oil. The profile nibbler is designed to cut corrugated, flat, and box steel forms. The tool is factory assembled with the punch oriented forward for cutting flat and shallow corrugated material. To cut deeper corrugated metals and box sections, rotate the head 90˚ to either side to use tool sideways. The shoe can be aligned in three positions: left, forward, and right. (See Figure 2). To rotate the head, loosen the set screw. Turn the head in the desired direction. NOTE: Do not rotate the head in a complete circle as this will change the punch engagement in the die. Rotate the shoe and turn the set screw in until you feel the set screw engage a recess in the shoe. Tighten the set screw firmly. Periodically recheck this screw for tightness. Sharpening Punches Never cut with a blunt, dull punch or die. Punches can be sharpened 2
