SPECIFIC SAFETY INSTRUCTIONS

Please read these safety instructions carefully, remember them and keep them in a safe place
WARNING! When using electric machinery and power tools, it is important to abide by and adhere to the following safety instructions for reasons of protection against injury caused by electric current, injury of persons and risk of starting fi res. The term “power tools” used in the instructions below refers to power tools that are plugged into a power supply (by a power cord) as well as tools running on a battery pack (cordless). Keep all warnings and instructions for further use.

Work environment

• Keep the work area clean and well lit. Untidiness and dark places on the job site are usually causes of accidents. Store tools that are not used.
• Do not use power tools in an environment where there is risk of starting a fire or explosion; this refers to places where there are flammable liquids, gases or dust. Sparks form on the power tool’s commutator, which can cause dust or fume ignition.
• When using power tools, unauthorized persons, especially children, should be denied entry to the job site! In case you are interrupted, you can lose control of the current activity. In any case, do not leave the power tool without supervision. Prevent animals from approaching the equipment.

Electrical safety

• The power tool’s power plug must correspond to the power outlet. Never alter the plug in any way. If the tool’s plug has a safety peg, never use an adapter of any kind. Undamaged plugs and corresponding outlets prevent the risk of injury by electric current.
• If the power cord is damaged, it must be replaced by a new power cord that can be obtained from an authorized service centre or the importer.
• Avoid bodily contact with grounded items, e.g. piping, radiators, kitchen ranges and refrigerators. The risk of injury by electric current is greater if your body is connected to the ground.
• Do not expose power tools to rain, moisture or dampness. Never touch power tools with wet hands. Never wash power tools with running water and never submerse them into water.
• Do not use the power cord for any other purpose than originally intended. Never carry or pull the power tools by the power cord. Do not pull the plug out of the outlet by pulling on the cord. Avoid mechanical damage to the power cord by sharp or hot objects.
• Power tools were manufactured exclusively for the AC power supply. Always check if the electrical voltage corresponds to the data printed on the tool’s serial number label.
• Never work with a tool that has a damaged power cord or plug, or that has fallen on the ground and is damaged in any way.
• In the case of using an extension cord, always check that its technical parameters correspond to the data printed on the tool’s serial number label.
• If the power tool is used outdoors, use an extension cord that is appropriate for exterior use. When using an extension cable drum, the cord must be unwound to prevent the cord from overheating. If the power tool is used in moist areas or outdoors, it is permitted to use it only if it is plugged into an electric circuit with a residual current device ≤30 mA. Using a circuit with an RCD lowers the risk of injury by electric current.
• Grasp hand power tools at the designated isolated grip areas because, during operation, one may come into contact with the cutting or drilling fittings with a hidden conductor or with the power cord.

Personal safety

• When using a power tool, be careful and alert, pay special attention to the activity you are doing. Concentrate on your work. Do not work with power tools if you are tired or if you are under the influence of drugs, alcohol or medication. When using power tools, even a momentary lapse in attentiveness can lead to severe personal injury. Do not eat, drink or smoke while working with power tools.

• Use protective gear. Always use eye protection. Use protective gear corresponding to the type of work you are doing. Protective gear such as respirators, safety shoes with antiskid treatment, head protection or ear protection, used in accordance with working conditions, lower the risk of personal injury.

• Avoid unintentional operation of tools. Do not carry tools that are plugged into the electric grid with your finger on the switch or release trigger.

• Before connecting the tool to a power supply, make sure that the switch or release trigger are in the “off” position. Carrying tools with your finger on the switch or plugging the tool into an outlet with the switch in the “on” position can cause serious injury. Before turning tools on, remove all adjustment wrenches and tools.
  The adjustment wrench or tool that stays connected to the rotating part of the power tool can cause personal injury.

• Always stand fi rmly and keep your balance. Work only in places that you can reach safely. Never overestimate your own strength. Do not use power tools if you are tired.

• Dress appropriately. Use working clothes. Do not wear loose clothing or jewellery. Make sure that your hair, clothing, gloves or other body parts do not come overly close to rotating or heated parts of the power tool. Connect the equipment to the dust exhaust. If the tool offers the possibility to connect equipment for capturing dust or dust suction, make sure that it is properly connected and used. Using this equipment can reduce danger resulting from dust.

• Firmly fasten the workpiece. Use a carpenter’s clamp or vice to secure the piece you will be cutting.

• Do not use power tools if you are under the influence of alcohol, drugs, medication or other narcotics or addictive substances.

• This equipment is not intended to be used by persons with limited physical, sensory or mental abilities (including children) or persons with insufficient experience and knowledge, unless they are supervised or received instructions to use the equipment from a person responsible for his/her safety. Children must be supervised in order to ensure that they are not playing with the equipment.

Using cordless tools

• Before inserting the battery, make sure that the switch is in the “0-off” position. Inserting the battery into a running tool can cause dangerous situations.
• To charge the battery, only use chargers that are specifi ed by the manufacturer. Using a charger for a different kind of battery can cause damage to the battery and result in fire.
• Only use batteries that are designated for the given tool. Using other batteries can cause injury or result in fire.
• If the battery is not used, store it away from metal objects such as clamps, wrenches, screws and other small metal objects that could cause the connection of one battery contact with the other. Short-circuiting the battery can cause injury, burns or fire.
• Handle batteries with care. In the case of improper care, chemical substances can leak from the battery. Avoid coming into contact with this substance and if you do come into contact with it, rinse the affected area under running water. If the chemical substance comes into contact with the eye, immediately seek out medical attention. The chemical substance from the battery can cause serious injury.

Service

• Do not change parts of the tool, do not perform repairs on your own and do not interfere with the tool’s construction in any way. Leave tool repairs to qualifi ed persons.
• Each repair or product modifi cation performed without our company’s permission is inadmissible (it can cause injury or harm to the user).
• Always leave tools to be repaired in a certified service centre. Use only original or recommended spare parts. This will ensure your and your tool’s safety.

Kickback and related warnings

• 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 in turn 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 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. 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.

• Maintain a fi 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.

• Never place your hand near the rotating accessory. Accessory may kickback over your hand.

• 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.

• 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.

• Do not attach a saw chain woodcarving blade or toothed saw blade. Such blades create frequent kickback and loss of control.

• WARNING! Before use, please read these safety instructions and keep them in a safe place.

• Upon failure to follow the instructions specifi ed in this manual, there is a risk of injury.

• Angle grinder conforms to applicable technical regulations and standards.

• Do not use other accessories except for grinding, cutting and diamond discs.

• Never use the tools without the safety screen.

• Always use eye protection (protective goggles or safety shield) and hearing protection.

• Do not use any cutting and grinding discs for side grinding.

• Make sure to keep the vents free of any obstacles during dusty work.

• During wall cutting check that there are no electric lines in the walls (using metal detector).

• Never water-cool grinding disc.

• Do not touch the edge after machining, it may be hot.

• Never attach the grinding machine to the work bench.

• Make sure that the rotational speed specifi ed on the grinding disc is higher than or equals the rotational speed of the angle grinder specifi ed in the type label.

• Do not cut any material that requires a cut with maximum depth exceeding the depth of the grinding disc. Do not cut and grind light metals with higher magnesium content than 80% as such metals are fl ammable. Make sure that the grinding disc has the right dimensions and is correctly mounted on the spindle.

• Handle the grinding discs very carefully and in accordance with instructions supplied with the grinding disc. Inspect the grinding disc before each use.

• Do not use grinding discs that are cracked or otherwise damaged.

• Make sure that the grinding disc is mounted according to instructions.

• After mounting the grinding disc, let the grinder run at idle speed in a safe place. If the grinder shows strong vibrations or if the grinding disc shows visible damage, immediately turn off the grinder and try to identify the cause.

• Do not use any reducers or other auxiliary ports for mounting grinding discs intended for different spindle diameter.

• Make sure that the material is adequately supported or fixed. Never use grinding disc to remove burrs.

• Make sure to prevent the sparks from hitting a person or igniting infl ammable goods.

• Do network with the grinder if someone is standing in the line of the grinding disc. Make sure to clean up the working area around you.

• Press the locking knob of the disc (3) only after the engine and spindle of the grinder hove completely stopped !

• Remember that the grinding disc will continue to rotate for a while otter switching off the grinder due to inertia.

• Always use the auxiliary handle supplied with the tool. Loss of control over the electric tools could cause injury.

• WARNING! Use means of protection against noise, dust and vibrations !!!

• WARNING! Keep these safety instructions !!!

Safety warnings specific for Grinding and Abrasive Cutting-Off operations

• Use only wheel types that are recommended for your power tool and the specifi c guard designed for the selected wheel. Wheels for which the power tool was not designed cannot be adequately guarded and are unsafe.

• 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. 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 operator from broken wheel fragments, accidental contact with wheel and sparks that could ignite clothing.

• 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.

• Always use undamaged wheel flanges that are of correct size and shape for your selected wheel. Proper wheel fl anges support the wheel thus reducing the possibility of wheel breakage. Flanges for cut-off wheels may be different from grinding wheel fl anges.

• Do not use worn down reinforced wheels from larger power tools. Wheels intended for larger power tools are not suitable for the higher speed of a smaller tool and may burst.

• Additional safety warnings specifi c 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. Overstressing the wheel increases the loading and susceptibility to twisting or binding of the wheel in the cut possibility of kickback or wheel breakage.

• 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.

• When 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.

• 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.

• 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.

• 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.
  Safety warnings specific for sanding operations

• Do not use excessively oversized sanding disc paper. Follow manufacturers recomme ndations, 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.
  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.T he wire bristles can easily penetrate light clothing and/or skin.

• If the use of 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 work load and centrifugal forces.

WORKING WITH ANGLE GRINDER

• The optimum angle of disc to work piece is 150°.
• Maintain the largest possible distance between the disc and operator.
• Exert only slight pressure and no lateral load on the disc. Note the direction of rotation and watch out for fl ying sparks.
• Avoid knocking the work piece.
• If the disc diameter is less than 80 mm, change the disc.
