6 enDo not operate the power tool near flammablematerials. Sparks could ignite these materials.Do not use accessories that require liquidcoolants. Using water or other liquid coolantsmay result in electrocution or shock.Further safety warnings for all appli-cationsKickback and related warningsKickback is the sudden reaction to a pinchedor snagged rotating application tool, such as agrinding wheel, sanding belt, wire brush, etc.Pinching or snagging causes the rotating appli-cation tool to rapidly stop. This causes anuncontrolled power tool to be forced in thedirection opposite of the application tool'srotation direction.For example, if a grinding wheel is snagged orpinched in the workpiece, the edge of thegrinding wheel that is entering into the work-piece can be caught, causing the grindingwheel to break out or cause kickback. Thegrinding wheel may either jump toward oraway from the operator, depending on thedirection of the wheel at the point of block-ing. Grinding wheels can also break underthese conditions.Kickback is the result of power tool misuse orincorrect operating procedures. It can beavoided by taking proper precautions asdescribed below.Maintain a firm grip on the power tool andposition your body and arms to allow you toresist kickback forces. The operator can con-trol torque reactions or kickback forces, ifproper precautions are taken.Use special care when working corners, sharpedges, etc. Avoid bouncing and snagging theaccessory. Corners, sharp edges or bouncinghave a tendency to snag the rotating accessoryand cause loss of control or kickback.Do not use toothed saw blades. Such applica-tion tools create frequent kickback or loss ofcontrol over the power tool.Always feed the application tool into thematerial in the same direction as the cuttingedge is exiting from the material (which is thesame direction as the chips are thrown).Guiding the power tool in the wrong direc-tion causes the cutting edge of the applicationtool to climb out of the workpiece and pullthe tool in the direction of this feed.Always clamp the workpiece when usingrotating files, cutting discs, carbide (TC) orhigh-speed grinding tools. These applicationtools will pinch or grab if they become slightlycanted in the groove, and can kickback. Whena cutting disc grabs, the disc itself usuallybreaks. When rotating files, carbide (TC) orhigh-speed grinding tools pinch or grab, thetool insert may jump from the groove andyou could lose control of the tool.Never place your hand near the rotatingaccessory. Accessory may kickback overyour hand.Do not position your body in the area wherepower tool will move if kickback occurs. Kick-back will propel the tool in direction oppositeto the wheel’s movement at the point of snag-ging.Additional safety warnings for grind-ing and cut-off grindingSafety warnings specific for grindingand cut-off grinding:Use only grinding accessories that areapproved for your power tool and only for therecommended applications. Example: Nevergrind with the lateral surface of a cuttingdisc. Cutting discs are intended for materialremoval using the edge of the disc. Lateralforce exerted on these grinding accessoriescan cause them to break.For threaded conical and straight grindingpoints/accessories, use only undamagedmandrels of correct size and length with anunrelieved shoulder flange. Suitable mandrelswill reduce the possibility of breakage.Do not jam or seize the cutting disc or applyexcessive pressure. Do not make excessivelydeep cuts. Overstressing the cutting discincreases the loading and susceptibility towedging or binding in the cut, and thusincreases the possibility of kickback or discbreakage.Keep your hands clear of the area in front andbehind the rotating cutting disc. When mov-ing the cutting disc in the workpiece awayfrom your hand, possible kickback may pro-pel the power tool with the spinning discdirectly at you.OBJ_BUCH-0000000187-001.book Page 6 Thursday, January 29, 2015 1:11 PM
