Angle Grinder Safety Warnings Safety Warnings Common for Grinding, Sanding or Abrasive Cutting-O Operations: a) This power tool is intended to function as a grinder, sander or cut-o tool. Read all safety warnings, instructions, illustrations and speci- cations provided with this power tool. Failure to follow all instructions listed below may result in electric shock, re and/or serious injury. b) Operations such as wire brushing and poli- shing are not recommended to be performed with this power tool. Operations for which the pow- er tool was not designed may create a hazard and cause personal injury. c) Do not use accessories which are not speci- cally designed and recommended by the tool manufacturer. Just because the accessory can be attached to your power tool, it does not assure safe operation. d) The rated speed of the accessory must be at least equal to the maximum speed marked on the power tool. Accessories running faster than their rated speed can break and y apart. e) The outside diameter and the thickness of your accessory must be within the capacity rating of your power tool. Incorrectly sized accessories cannot be adequately guarded or controlled. f) Treaded mounting of accessories must match the grinder spindle thread. For accessories mounted by anges, the arbour hole of the accessory must t the locating diameter of the ange. Accessories that do not match the mounting hardware of the power tool will run out of balance, vibrate excessively and may cause loss of control. g) Do not use a damaged accessory. Before each use inspect the accessory such as abrasive wheels for chips and cracks, backing pad for cracks, tear or excess wear, wire brush for loose or cracked wi

res. If power tool or accessory is dropped, inspect for damage or install an undamaged accessory. After inspecting and installing an accessory, position yourself and bystanders away from the plane of the rotating accessory and run the power tool at maximum noload speed for one minute. Damaged accessories will normally break apart during this test time. h) Wear personal protective equipment. De- pending on application, use face shield, safety goggles or safety glasses. As appropriate, wear dust mask, hearing protectors, gloves and shop apron capable of stopping small abrasive or workpiece fragments. The eye protection mustD

ENGLISH DEGB be capable of stopping ying debris generated by various operations. The dust mask or respirator must be capable of ltrating particles generated by your operation. Prolonged exposure to high intensity noise may cause hearing loss.

i) Keep bystanders a safe distance away from

work area. Anyone entering the work area must wear personal protective equipment. Fragments of workpiece or of a broken accessory may y away and cause injury beyond immediate area of operation. j) Hold the power tool by insulated gripping sur

faces only, when performing anoperation where the cutting accessory may contact hidden wiring or its own cord. Cutting accessory contacting a „live“ wire may make exposed metal parts of the power tool „live“ and could give the operator an electric shock. k) Position the cord clear of the spinning accesso- ry. If you lose control, the cord may be cut or snagged and your hand or arm may be pulled into the spinning wheel. l) Never lay the power tool down until the acces- sory has come to a complete stop. The spinning accessory may grab the surface and pull the power tool out of your control. m) Do not run the power tool while carrying it at your side. Accidental contact with the spinning acces- sory could snag your clothing, pulling the accessory into your body. n) Regularly clean the power tool’s air vents. The motor’s fan will draw the dust inside the housing and excessive accumulation of powdered metal may cause electrical hazards. o) Do not operate the power tool near ammable materials. Sparks could ignite these materials. p) Do not use accessories that require liquid coolants. Using water or other liquid coolants may result in electrocution or shock. Kickback and Related Warnings Kickback is a sudden reaction to a pinched or snagged rotating wheel. Pinching or snaggingcau

ses rapid stalling of the rotating wheel which in turn causes the uncontrolled power tool tobe forced in the direction opposite of the wheel’s rotation at the point of the binding. For example, if an abrasive wheel is snagged or pinched by the workpiece, the edge of the wheel that is entering into the pinch point can dig into the surface of the material causing the wheel to climb out or kick out. The wheel may either jump toward or away from the operator, depending on direction of the wheel’s movement at the point of pinching. Ab- rasive wheels may also break under these conditions. Kickback is the result of power tool misuse and/or incorrect operating procedures or conditions and can be avoided by taking proper precautions as given below. a) Maintain a rm grip on the power tool and position your body and arm to allow you to resist kickback forces. Always use auxiliary handle, if provided, for maximum control over kickback or torque reaction during start-up. The operator can control torque reactions or kickback forces, if proper precautions are taken. b) Never place your hand near the rotating ac

cessory. Accessory may kickback over your hand. c) Do not position your body in the area where power tool will move if kickback occurs. Kickback will propel the tool in direction opposite to the wheel’s movement at the point of snagging. d) Use special care when working corners, sharp edges etc. Avoid bouncing and snagging the accessory. Corners, sharp edges or bouncing have a tendency to snag the rotating accessory and cause loss of control or kickback. e) Do not attach a saw chain woodcarving blade or toothed saw blade. Such blades create frequent kickback and loss of control.toothed saw blade. Safety Warnings Specic for Grinding and Abrasi

ve Cutting-O Operations: a) Use only wheel types that are recommended for your power tool and the specic guard desi- gned for the selected wheel. Wheels for which the power tool was not designed cannot be adequately guarded and are unsafe. b) The grinding surface of the centre depressed wheels must be mounted below the plane of the guard lip. An improperly mounted wheel that projects through the plane of the guard lip cannot be adequately protected. c) The guard must be securely attached to the power tool and positioned for maximum safety, so the least amount of wheel is exposed towards the operator. The guard helps to protect the opera

tor from broken wheel fragments, accidental contact with wheel and sparks that could ignite clothing. d) Wheels must be used only for recommended applications. For example: do not grind with the side of cut-o wheel. Abrasive cut-o wheels are intended for peripheral grinding, side forces applied to these wheels may cause them to shatter. e) Always use undamaged wheel anges that are of correct size and shape for your selected wheel. Proper wheel anges support the wheel thus reducing the possibility of wheel breakage. Flanges for cut-o wheels may be dierent from grinding wheel anges. f) Do not use worn down wheels from larger power tools.Wheel intended for larger power tool is not suitable for the higher speed of a smaller tool and may burst. Additional Safety Warnings Specic for Abrasive Cutting-O Operations: a) Do not “jam” the cut-o wheel or apply excessi

ve pressure. Do not attempt to make an excessive depth of cut. Overstressing the wheel increases the loading and susceptibility to twisting or binding of the wheel in the cut and the possibility of kickback or wheel breakage.D

b) Do not position your body in line with and behind the rotating wheel. When the wheel, at the point of operation, is moving away from your body, the possible kickback may propel the spinning wheel and the power tool directly at you. c) When wheel is binding or when interrupting a cut for any reason, switch o the power tool and hold the power tool motionless until the wheel co- mes to a complete stop. Never attempt to remove the cut-o wheel from the cut while the wheel is in motion otherwise kickback may occur. Investigate and take corrective action to eliminate the cause of wheel binding. d) Do not restart the cutting operation in the workpiece. Let the wheel reach full speed and carefully re-enter the cut. The wheel may bind, walk up or kickback if the power tool is restarted in the workpiece. e) Support panels or any oversized workpiece to minimize the risk of wheel pinching and kickback. Large workpieces tend to sag under their own weight. Supports must be placed under the workpiece near the line of cut and near the edge of the workpiece on both sides of the wheel. f) Use extra caution when making a “pocket cut” into existing walls or other blind areas. The pro

truding wheel may cut gas or water pipes, electrical wiring or objects that can cause kickback. Safety Warnings Specic for Sanding Operations: a) Do not use excessively oversized sanding disc paper. Follow manufacturers recommendations, when selecting sanding paper. Larger sanding paper extending beyond the sanding pad presents a laceration hazard and may cause snagging, tearing of the disc or kickback. Additional Safety and Working Instructions When grinding metal, ying sparks are produced. Take care that no persons are endangered. Because of the danger of re, no combustible materials should be located in the vicinity (spark ight zone). Do not use dust extraction. Avoid ying sparks and sanding dust hit your body. Never reach into the danger area of the machine when it is running. Chips and splinters must not be removed while the machine is running. Immediately switch o the machine in case of con

siderable vibrations or if other malfunctions occur. Check the machine in order to nd out the cause. Do not let any metal parts reach the airing slots - danger of short circuit! Under extreme conditions (e.g. smooth-grinding metals with the arbour and vulcanized bre grinding wheel), signicant contamination can build up on the inside of the angle grinder. For safety reasons, in such conditions the inside should be cleaned thoroughly of metal deposits and a motor circuit- breaker must be connected in series. If the motor circuit-breaker trips the machine must be sent for repair. For accessories intended to be tted with threaded hole wheel, ensure that the thread in the wheel is long enough to accept the spindle length. Always use and store the cutting and grinding disks according to the manufacturer‘s instructions. Always use the correct guard for cutting and grinding. Always use guard with cutting guide from the acces

sories range for cutting stone. The adjusting nut must be tightened before starting to work with the machine. Always use the auxiliary handle. The workpiece must be xed if it is not heavy enough to be steady. Never move the workpiece towards the rotating disk by hand. STARTUP PROTECTION 58107: Machines with a lockable switch are supplied with a restart cutout. This prevents the machine rest

arting by itself after a power failure. When resuming work, switch the machine o and then switch it back on again.
