WARNING!
Read all safety warnings and all instructions. Failure to follow the warnings and instructions 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 your mains-operated (corded) power tool or battery- operated (cordless) power tool.

WORK AREA SAFETY

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

ELECTRICAL SAFETY

• Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools.
• Unmodified plugs and matching outlets will reduce the risk of electric shock.
• 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.
• Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
• 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.
• 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.
• 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.

PERSONAL SAFETY

• Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication.
• A moment of inattention while operating power tools may result in serious personal injury.
• Using personal protection for appropriate conditions will reduce personal injuries.
• Prevent unintentional starting. Ensure the switch is the off-position before connecting to a 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.
• Remove any adjusting key or wrench before turning the power tool on.
• A wrench or a key left attached to a rotating part of the power tool may result in personal injury.
• Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
• Dress properly. Do not wear loose clothes or jewellery. Keep your hair,t clothes and gloves away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.
• If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. The use of dust collection can reduce dust-related hazards.

POWER TOOL USE AND CARE

• 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 for which it was designed.
• Do not use the power tool if the switch does not turn on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.
• Disconnect the plug from the power source and/or the battery pack 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.
• Store idle power tools within 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 the hands of untrained users.
• Maintain power tools. 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.
• Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
• Use the power tool, accessories 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.

SERVICE

• Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.
• This power tool is intended to function as a grinder, sander, wire brush, polisher or cut-off toll.
• 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.
• Do not use accessories that are not specifically designed and recommended by the tool manufacturer. Just because the accessory can be attached to your power tool, it does not assure safe operation.
• 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.
• The arbour size of wheels, flanges, backing pads or any other accessory must properly fit the spindle of the power tool. Accessories with arbour holes that do not match the mounting hardware of the power tool will run out of balance, vibrate excessively and may cause loss of control.
• Do not use a damaged accessory. Before each use inspect the accessories such as abrasive wheels for chips and cracks, a backing pad for cracks tears or excess wear, and a wire brush for loose or cracked wires. If power tool or 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.
• 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 filtrating particles generated by your operation. Prolonged exposure to high-intensity noise may cause hearing loss.
• Keep bystanders a safe distance away from the work area. Anyone entering the work area must wear personal protective equipment. Fragments of workpieces or a broken accessory may fly away and cause injury beyond the immediate area of operation.
• Hold 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 shock the operator.
• 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.
• Never lay the power tool down until it has stopped completely
• 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.
• Regularly clean the power tool’s air vents. The motor’s fan will draw dust inside the housing and excessive accumulation of powdered metal may cause electrical hazards.
• Do not operate the power tool near flammable materials. Sparks could ignite coolants may result in electrocution or shock.

KICKBACK AND RELATED WARNINGS
Kickback is a sudden reaction to a pinched or snagged rotating wheel, backing pad, 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 the 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 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.
• Never place your hand near the rotating accessory. The accessory may kick back over your hand.
• Do not position your body in the area where the power tool will move if kickback occurs. Kickback will propel the tool in a 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 or bounced edges tend to snag the rotating accessory and cause loss of control or kickback.
• Do not attack a saw chain woodcarving blade or toothed saw blade. Such blades create frequent kickbacks and loss of control.

SAFETY WARNINGS SPECIFIC FOR GRINDING AND ABRASIVE CUTTING-OFF OPERATIONS

• Use only wheel types that are recommended for your power tool and the specific guard designs cannot be adequately guarded and are unsafe.
• The guard must be securely attached to the power tool positioned for maximum safety, so the least amount of wheel is exposed towards the operator. The guard helps to protect the operator from broken wheel fragments and accidental contact with the wheel.
• 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.
• Do not restart the cutting operation in the workpiece. Let the wheel reach full speed and carefully reenter the cut. The wheel may bind, walk up or kick back 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 snag under their weight. Supports must be placed under the workpiece near the line of cut and 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.

OPERATIONS

• Do not use excessively oversized sanding disc paper. Follow the manufacturer’s recommendations, when selecting sanding paper.
• Larger sanding paper extending beyond the sanding pad presents a laceration hazard and may cause snag, tearing of the disc or kickback.
• Be aware that wire bristles are thrown by the brush even during ordinary operations. 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 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.

ADDITIONAL SAFETY REGULATIONS

• Wear safety goggles.
• Use suitable detectors to determine if utility lines are hidden in the work area or call the local utility company for assistance.
• Contact with electric lines can lead to fire and electric shock. Damaging a gas line can lead to an explosion. Penetrating a water line causes property damage or may cause an electric shock.
• Release the on/off switch and set it to the off position when the power supply is interrupted, e.g., in case of a power failure or when the mains plug is pulled. This prevents uncontrolled restarting.
• When working stone, use dust extraction. The vacuum cleaner must be approved for the extraction of stone dust.
• Using this equipment reduces dust-related hazards.-Use a cutting guide when cutting stones. Without sideward guidance, the cutting disc can jam and cause kickback.
• When working stone, use dust extraction. The vacuum cleaner must be approved for the extraction of stone dust. Using this equipment reduces dust-related hazards.
• When working with the machine, always hold it firmly with both hands and provide for a secure stance. The power tool is guided more securely with both hands.
• Secure the workpiece. A workpiece clamped with clamping devices or in a vice is held more securely than by hand.
• Keep your workplace clean. Blends of materials are particularly dangerous. Dust from light alloys can burn or explode.
• Never use the machine with a damaged cable. Do not touch the damaged cable and pull the mains plug when the cable is damaged while working.
• Damaged cables increase the risk of an electric shock.

ASSEMBLY

WARNING!
Switch off the die grinder and disconnect it from the powerpoint.

NOTE
Make sure the main voltages match the machine’s rating label.

FITTING THE GRINDING POINT

• Insert the grinding points on the hole of the central spindle (2), then adjust the grinding point to the fit position distance away from the edge of the spindle.
• Rivet the spindle with the second spanner then tighten the collet nut firmly in a clockwise direction using the spanner.
• Make the die grinder run idle for at least a minute with the grinding point correctly assembled, the grinding point should be immediately replaced if there is a vibration.

WARNING!
Excessive pressure on the machine does not necessarily lead the high working power and speed; On the contrary, it increases the wear on the grinding point and can damage the die grinder.

NOTE

WARNING!
If the tool is operated continuously at low speeds for a long time, the motor will get overloaded, resulting in tool malfunction. The speed-adjusting dial can be turned only as far as 28000 and back to 12000. Do not force it past 28000 or 12000, or the speed adjusting function may no longer work.

OPERATING INSTRUCTION
NOTE
The die grinder can be used for grinding steel or ceramic workpieces such as pipe, box section, rectangular, angle iron steel bars, should, household bricks and tiles. Don’t attempt to grind a soft metal such as lead. The material will quickly “fill” the disc and render it useless. Before starting the grinder first ensure that the grinding point, collet nut and tool are in good condition. Do not cover ventilation when the tool is in use. This may cause damage to the motor and reduce the efficiency of the tool.

GRINDING
The best results are achieved with an angle of 0 to 30 for grinding. Move the machine left and right with light pressure. In this manner, the workpiece does not become too hot, no discolouration occurs and no ridges are produced.

WARNING!
When beginning the operation, must be ground with the little press, touch the small area of the piece, then increase the press stepwise underrated power.

MAINTENANCE AND INSPECTION

WARNING!
Regular inspection and maintenance of the part of the mechanical of the machine every 100 hours, such as spindle, bearing etc., and if they are not agility, add the greasing to them replacing them in the authorized service agent if the bearing is damaged.
