What are the general power tool safety warnings? Read all safety warnings, instructions, illustrations, and specifications provided with the power tool. Failure to follow all instructions listed below may result in electric shock, fire, and/or serious injury. Save all warnings and instructions for future reference. The term “power tool” in the warnings refers to a mains-operated (corded) power tool or battery-operated (cordless) power tool.

What are the work area safety precautions?

1. Keep the work area clean and well-lit. Cluttered or dark areas invite accidents.
2. Do not operate power tools in explosive atmospheres, such as flammable liquids, gases, or dust. Power tools create sparks which may ignite the dust or fumes.
3. Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

What are the electrical safety precautions?

1. Power tool plugs must match the outlet. Never modify the plug. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce the risk of electric shock.
2. Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges, and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
3. Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
4. Do not abuse the cord. Never use the cord for carrying, pulling, or unplugging the power tool. Keep the cord away from heat, oil, sharp edges, or moving parts. Damaged or entangled cords increase the risk of electric shock.
5. When operating a power tool outdoors, use an extension cord suitable for outdoor use. The use of a cord suitable for outdoor use reduces the risk of electric shock.
6. If operating a power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply. The use of an RCD reduces the risk of electric shock.
7. Use a power supply via an RCD with a rated residual current of 30 mA or less.
8. Power tools can produce electromagnetic fields (EMF) that are not harmful to the user. However, users of pacemakers and other similar medical devices should contact the maker of their device and/or doctor for advice before operating this power tool.
9. Do not touch the power plug with wet hands.
10. If the cord is damaged, have it replaced by the manufacturer or its agent to avoid a safety hazard.

What are the personal safety precautions?

1. Stay alert, watch what you are doing, and use common sense when operating a power tool. Do not use a power tool while tired or under the influence of drugs, alcohol, or medication. A moment of inattention while operating power tools may result in serious personal injury.
2. Use personal protective equipment. Always wear eye protection. Protective equipment such as a dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.
3. Prevent unintentional starting. Ensure the switch is in the off-position before connecting to the power source and/or battery pack, picking up, or carrying the tool. Carrying power tools with your finger on the switch or energizing power tools that have the switch on invites accidents.
4. Remove any adjusting key or wrench before turning the power tool on. A wrench or key left attached to a rotating part of the power tool may result in personal injury.
5. Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
6. Dress properly. Do not wear loose clothing or jewelry. Keep hair and clothing away from moving parts. Loose clothes, jewelry, or long hair can be caught in moving parts.
7. If devices are provided for connecting dust extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can reduce dust-related hazards.
8. Do not let familiarity gained from frequent use of tools allow you to become complacent and ignore tool safety principles. A careless action can cause severe injury within a fraction of a second.
9. Always wear protective goggles to protect your eyes from injury when using power tools. The goggles must comply with ANSI Z87.1 in the USA, EN 166 in Europe, or AS/NZS 1336 in Australia/New Zealand. In Australia/New Zealand, wearing a face shield to protect your face is legally required. It is an employer’s responsibility to enforce using appropriate safety protective equipment by the tool operators and other persons in the immediate working area.

How should the power tool be used and cared for?

1. Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate it was designed.
2. Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.
3. Disconnect the plug from the power source and/or remove the battery pack, if detachable, from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.
4. Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in untrained users’ hands.
5. Maintain power tools and accessories. Check for misalignment or binding of moving parts, breakage of parts, and any other condition that may affect the power tool’s operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.
6. Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
7. Use the power tool, accessories, and tool bits, etc., by these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation.
8. Keep handles and grasping surfaces dry, clean, and free from oil and grease. Slippery handles and grasping surfaces do not allow for safe handling and control of the tool in unexpected situations.
9. When using the tool, do not wear cloth work gloves which may be entangled. The entanglement of cloth work gloves in the moving parts may result in personal injury.

What is the proper procedure for servicing the power tool?

2. Follow instructions for lubricating and changing accessories.

What are the general safety warnings for grinding, sanding, wire brushing, or abrasive cutting-off operations?

1. This 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 this power tool. Failure to follow all instructions listed below may result in electric shock, fire, and/or serious injury.
2. Operations such as polishing are not recommended with this power tool. Operations for which the power tool was not designed may create a hazard and cause personal injury.
3. Do not use accessories not specifically designed and recommended by the tool manufacturer. Just because the accessory can be attached to your power tool does not assure safe operation.
4. 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 fly apart.
5. The outside diameter and thickness of your accessory must be within the capacity rating of your power tool. Incorrectly sized accessories cannot be adequately guarded or controlled.
6. 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. 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.
7. Never stand in line with the rotating accessory. Always position yourself to the side of the tool, never in line with the rotating accessory. If kickback occurs, the tool and the rotating accessory may be projected directly at you, resulting in serious personal injury.
8. 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 wires. If the 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 no-load speed for one minute. Damaged accessories will normally break apart during this test time.
9. Wear personal protective equipment. Depending on the application, use a face shield, safety goggles, or safety glasses. As appropriate, wear a dust mask, hearing protectors, gloves, and a workshop apron capable of stopping small abrasive or workpiece fragments. The eye protection must be capable of stopping flying debris generated by various operations. The dust mask or respirator must be capable of filtering particles generated by your operation. Prolonged exposure to high-intensity noise may cause hearing loss.
10. Keep bystanders a safe distance away from the work area. Anyone entering the work area must wear personal protective equipment. Fragments of workpiece or a broken accessory may fly away and cause injury beyond the immediate area of operation.
11. Hold the power tool by insulated gripping surfaces only when performing an operation where the cutting accessory may contact hidden wiring or its 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.
12. Position the cord clear of the spinning accessory. If you lose control, the cord may be cut or snagged, and your hand or arm may be pulled into the spinning accessory.
13. Never lay the power tool down until the accessory has come to a complete stop. The spinning accessory may grab the surface and pull the power tool out of your control.
14. Do not run the power tool while carrying it at your side. Accidental contact with the spinning accessory could snag your clothing, pulling the accessory into your body.
15. 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.
16. Do not operate the power tool near flammable materials. Sparks could ignite these materials.
17. Do not use accessories that require liquid coolants. Using water or other liquid coolants may result in electrocution or shock.

What is kickback? Kickback is a sudden reaction to a pinched or snagged rotating wheel, backing pad, brush, or any other accessory. Pinching or snagging causes rapid stalling of the rotating accessory, which causes the uncontrolled power tool to be forced in the direction opposite of the accessory’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 entering 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 the wheel’s movement direction at the point of pinching. Abrasive 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.

What precautions can be taken to avoid kickback?

1. 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. The operator can control torque reactions or kickback forces if proper precautions are taken.
2. Never place your hand near the rotating accessory. The accessory may kick back over your hand.
3. Do not position your body in the area where the power tool will move if kickback occurs. Kickback will propel the tool in the direction opposite to the wheel’s movement at the point of snagging.
4. Use special care when working corners, sharp edges, etc. Avoid bouncing and snagging the accessory. Corners, sharp edges, or bouncing tend to snag the rotating accessory and cause loss of control or kickback.
5. Do not attach a saw chain woodcarving blade or toothed saw blade. Such blades create frequent kickback and loss of control.

What are the specific safety warnings for grinding and abrasive cutting-off operations?

1. Use only wheel types recommended for your power tool and the specific guard designed for the selected wheel. Wheels for which the power tool was not designed cannot be adequately guarded and are unsafe.
2. The grinding surface of center 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.
3. The guard must be securely attached to the power tool and positioned for maximum safety so that the least amount of wheel is exposed towards the operator. The guard helps to protect the operator from broken wheel fragments, accidental contact with the wheel, and sparks that could ignite clothing.
4. Wheels must be used only for recommended applications. For example: do not grind with the side of the cut-off wheel. Abrasive cut-off wheels are intended for peripheral grinding, side forces applied to these wheels may cause them to shatter.
5. Always use undamaged wheel flanges that are of the correct size and shape for your selected wheel. Proper wheel flanges support the wheel, thus reducing the possibility of wheel breakage. Flanges for cut-off wheels may be different from grinding wheel flanges.
6. Do not use worn-down wheels from larger power tools. A wheel intended for a larger power tool is not suitable for the higher speed of a smaller tool and may burst.

What are the additional safety warnings for abrasive cutting-off operations?

1. Do not “jam” the cut-off wheel or apply excessive 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.
2. 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.
3. 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. Investigate and take corrective action to eliminate the cause of wheel binding.
4. 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 kick back if the power tool is restarted in the workpiece.
5. 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.
6. Use extra caution when making a “pocket cut” into existing walls or other blind areas. The protruding wheel may cut gas or water pipes, electrical wiring, or objects that can cause kickback.

What are the specific safety warnings 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 specific safety warnings for wire brushing operations?

1. 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.
2. If using a guard is recommended for wire brushing, do not allow any interference of the wire wheel or brush with the guard. Wire wheel or brush may expand in diameter due to workload and centrifugal forces.

What are the additional safety warnings for grinder operations?

1. When using depressed center grinding wheels, be sure to use only fiberglass-reinforced wheels.
2. NEVER USE Stone Cup-type wheels with this grinder. This grinder is not designed for these types of wheels, and using such a product may result in serious personal injury.
3. Be careful not to damage the spindle, the flange (especially the installing surface), or the lock nut. Damage to these parts could result in wheel breakage.
4. Make sure the wheel is not contacting the workpiece before the switch is turned on.
5. 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.
6. Use the specified surface of the wheel to perform the grinding.
7. Do not leave the tool running. Operate the tool only when hand-held.
8. Do not touch the workpiece immediately after operation; it may be extremely hot and could burn your skin.
9. Do not touch accessories immediately after operation; it may be extremely hot and could burn your skin.
10. Observe the manufacturer’s instructions for correctly mounting and using wheels. Handle and store wheels with care.
11. Do not use separate reducing bushings or adapters to adapt large hole abrasive wheels.
12. Use only flanges specified for this tool.
13. 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.
14. Check that the workpiece is properly supported.
15. Pay attention that the wheel continues to rotate after the tool is switched off.
16. If the workplace is extremely hot and humid, or badly polluted by conductive dust, use a short-circuit breaker (30 mA) to assure operator safety.
17. Do not use the tool on any materials containing asbestos.
18. When using a cut-off wheel, always work with the dust collecting wheel guard required by domestic regulation.
19. Cutting discs must not be subjected to lateral pressure.
20. Do not use cloth work gloves during operation. Fibers from cloth gloves may enter the tool, which causes tool breakage.
21. Ensure no electrical cables, water pipes, gas pipes, etc., could cause a hazard if damaged by using the tool.
