MAKITA DGA505 (01) PDF SUMMARY:
What should I read before using the cordless angle grinder?
Read the instruction manual before using the cordless angle grinder.
What are the safety precautions I should take while working with power tools?
Follow safety warnings and instructions, as failure to do so may result in electric shock, fire, or serious injury. Keep the work area clean and well-lit to avoid accidents. Do not operate power tools in explosive atmospheres. Keep children and bystanders away while operating a power tool. Power tool plugs must match the outlet, and adapter plugs should not be used with earthed power tools. Avoid body contact with earthed or grounded surfaces. Power tools should not be exposed to rain or wet conditions. Do not abuse the cord and keep it away from heat, oil, sharp edges, or moving parts. When operating a power tool outdoors, use an extension cord suitable for outdoor use. If operating a power tool in a damp location is unavoidable, use a ground fault circuit interrupter (GFCI) protected supply. Stay alert, watch what you are doing, and use common sense when operating a power tool. Use personal protective equipment, including eye protection. Ensure the switch is in the off-position before connecting to power source and/or battery pack, picking up or carrying the tool. Remove any adjusting key or wrench before turning the power tool on. Do not overreach and maintain proper footing and balance. Dress properly and keep hair, clothing, and gloves away from moving parts. If devices are provided for dust extraction and collection, ensure they are connected and properly used.
What are the general safety warnings for grinding, sanding, wire brushing, or abrasive cutting-off operations?
The power tool is intended to function as a grinder, sander, wire brush, or cut-off tool. Read all safety warnings, instructions, illustrations, and specifications provided with the power tool. Failure to follow all instructions may result in electric shock, fire, and/or serious injury. Operations such as polishing are not recommended. Do not use accessories that are not specifically designed and recommended by the tool manufacturer. The rated speed of the accessory must be at least equal to the maximum speed marked on the power tool. The outside diameter and the thickness of the accessory must be within the capacity rating of the power tool. Threaded mounting of accessories must match the grinder spindle thread. For accessories mounted by flanges, the arbor hole of the accessory must fit the locating diameter of the flange. Do not use a damaged accessory. Before each use, inspect the accessory. Wear personal protective equipment, including face shield, safety goggles, or safety glasses. Keep bystanders a safe distance away from the work area. Hold the power tool by insulated gripping surfaces only when performing an operation where the cutting tool may contact hidden wiring. Never lay the power tool down until the accessory has come to a complete stop. Do not run the power tool while carrying it at your side. Regularly clean the power tool’s air vents. Do not operate the power tool near flammable materials. Do not use accessories that require liquid coolants.
What is kickback, and how can I avoid it?
Kickback is a sudden reaction to a pinched or snagged rotating wheel, backing pad, brush, or any other accessory. It can be avoided by taking proper precautions. Maintain a firm grip on the power tool and position your body and arm to allow you to resist kickback forces. Always use an auxiliary handle, if provided, for maximum control over kickback or torque reaction during start-up. Never place your hand near the rotating accessory. Do not position your body in the area where the power tool will move if kickback occurs. Use special care when working corners, sharp edges, etc. Avoid bouncing and snagging the accessory. Do not attach a saw chain woodcarving blade or toothed saw blade.
What are the safety warnings specific to grinding and abrasive cutting-off operations?
Use only wheel types that are recommended for the power tool and the specific guard designed for the selected wheel. The grinding surface of center depressed wheels must be mounted below the plane of the guard lip. 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. Wheels must be used only for recommended applications. Always use undamaged wheel flanges that are of correct size and shape for the selected wheel. Do not use worn-down wheels from larger power tools.
What are the additional safety warnings specific for abrasive cutting-off operations?
Do not “jam” the cut-off wheel or apply excessive pressure. Do not attempt to make an excessive depth of cut. Do not position your body in line with and behind the rotating wheel. When the wheel is binding or when interrupting a cut for any reason, switch off the power tool and hold the power tool motionless until the wheel comes to a complete stop. Never attempt to remove the cut-off wheel from the cut while the wheel is in motion, otherwise kickback may occur. Do not restart the cutting operation in the workpiece. Support panels or any oversized workpiece to minimize the risk of wheel pinching and kickback. Use extra caution when making a “pocket cut” into existing walls or other blind areas.
What are the safety warnings specific for sanding operations?
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.
What are the safety warnings specific for wire brushing operations?
Be aware that wire bristles are thrown by the brush even during ordinary operation. Do not overstress the wires by applying excessive load to the brush. The wire bristles can easily penetrate light clothing and/or skin. If the use of a guard is recommended for wire brushing, do not allow interference of the wire wheel or brush with the guard.
What are some additional safety warnings I should keep in mind?
When using depressed center grinding wheels, be sure to use only fiberglass-reinforced wheels. Never use stone cup-type wheels with this grinder. Be careful not to damage the spindle, the flange (especially the installing surface), or the lock nut. Make sure the wheel is not contacting the workpiece before the switch is turned on. Before using the tool on an actual workpiece, let it run for a while. Watch for vibration or wobbling that could indicate poor installation or a poorly balanced wheel. Use the specified surface of the wheel to perform the grinding. Do not leave the tool running. Operate the tool only when hand-held. Do not touch the workpiece immediately after operation; it may be extremely hot and could burn your skin. Observe the instructions of the manufacturer for correct mounting and use of wheels. Handle and store wheels with care. Do not use separate reducing bushings or adaptors to adapt large hole abrasive wheels. Use only flanges specified for this tool. For tools intended to be fitted with a threaded hole wheel, ensure that the thread in the wheel is long enough to accept the spindle length. Check that the workpiece is properly supported. Pay attention that the wheel continues to rotate after the tool is switched off. If the working place is extremely hot and humid or badly polluted by conductive dust, use a short-circuit breaker (30 mA) to assure operator safety. Do not use the tool on any materials containing asbestos. When using a cut-off wheel, always work with the dust collecting wheel guard required by domestic regulation. Cutting discs must not be subjected to any lateral pressure.
