Dewalt DCCS670X1 Instruction Manual - Page 6

English • Only use replacement bars and chains specified by the manufacturer. Incorrect replacement bars and chains may cause chain breakage and/or kickback. • Follow the manufacturer's sharpening and maintenance instructions for the saw chain. Decreasing the depth gauge height can lead to increased kickback. The Following Precautions Should Be Followed to Minimize Kickback: 1 . Grip saw firmly. Hold the chain saw firmly with both hands when the motor is running. Use a firm grip with thumbs and fingers encircling the chain saw handles. Chain saw will pull forward when cutting on the bottom edge of the bar, and push backward when cutting along the top edge of the bar. 2 . Do not over reach. 3 . Keep proper footing and balance at all times. 4 . Don't let the nose of the guide bar contact a log, branch, ground or other obstruction. 5 . Don't cut above shoulder height. 6 . Use devices such as low kickback chain and reduced kickback guide bars that reduce the risks associated with kickback. 7 . Only use replacement bars and chains specified by the manufacturer or the equivalent. 8 . Never let the moving chain contact any object at the tip of the guide bar. 9 . Keep the working area free from obstructions such as other trees, branches, rocks, fences, stumps, etc. Eliminate or avoid any obstruction that your saw chain could hit while you are cutting through a particular log or branch. 10 . Keep your saw chain sharp and properly tensioned. A loose or dull chain can increase the chance of kickback. Check tension at regular intervals with the motor stopped and tool unplugged, never with the motor running. 11 . Begin and continue cutting only with the chain moving at full speed. If the chain is moving at a slower speed, there is a greater chance for kickback to occur. 12 . Cut one log at a time. 13 . Use extreme caution when re-entering a previous cut. Engage ribbed bumpers into wood and allow chain to reach full speed before proceeding with cut. 14 . Do not attempt plunge cuts or bore cuts. 15 . Watch for shifting logs or other forces that could close a cut and pinch or fall into chain. Kickback Safety Features WARNING: The following features are included on your saw to help reduce the hazard of kickback; however such features will not totally eliminate this dangerous reaction. As a chain saw user do not rely only on safety devices. You must follow all safety precautions, instructions, and maintenance in this manual to help avoid kickback and other forces which can result in serious injury. • Reduced-Kickback Guide Bar, designed with a small radius tip which reduces the size of the kickback danger zone on bar tip. A reduced - kickback guide bar is one which has been demonstrated to significantly reduce the number and seriousness of kickbacks when tested in accordance with safety requirements for electric chain saws. • Low-Kickback Chain, designed with a contoured depth gauge and guard link which deflect kickback force and allow wood to gradually ride into the cutter. A low-kickback chain is a chain which has met kickback performance requirements of ANSI B175.1-2012. • Do not operate chain saw while in a tree, on a ladder, on a scaffold, or from any unstable surface. • Hold tool by insulated gripping surfaces when performing an operation where the cutting tool may contact hidden wiring. Contact with a "live" wire will make exposed metal parts of the tool "live" and shock the operator. • Do not attempt operations beyond your capacity or experience. Read thoroughly and understand completely all instructions in this manual. • Before you start chain saw, make sure saw chain is not contacting any object. • Do not operate a chain saw with one hand! Serious injury to the operator, helpers, or bystanders may result from one handed operation. A chain saw is intended for twohanded use only. • Keep the handles dry, clean, and free of oil or grease. • Do not allow dirt, debris, or sawdust to build up on the motor or outside air vents. • Stop the chain saw before setting it down. • Do not cut vines and/or small under brush. • Use extreme caution when cutting small size brush and saplings because slender material may catch the saw chain and be whipped toward you or pull you off balance. WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are: • lead from lead-based paints, • crystalline silica from bricks and cement and other masonry products, and • arsenic and chromium from chemicallytreated lumber. Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter out microscopic particles. • Avoid prolonged contact with dust from power sanding, sawing, grinding, drilling, and other construction activities.
