Special safety warnings

Safety warnings common for grinding, sanding, wire brushing, polishing or abrasive cutting-off operations:

• This power tool is intended to function as a grinder, sander, wire brush, polisher 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.

• Operations such as grinding, sanding, wire brushing, polishing or cutting-off are not recommended to be performed with this power tool. Operations for which the power tool was not designed may create a hazard and cause personal injury.

• Do not use accessories which 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 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.

• 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 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 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.

• Wear personal protective equipment. Depend- ing on application, use face shield, safety goggles or safety glasses. As appropriate, wear dust mask, hearing protectors, gloves and 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 work area. Anyone entering the work area must wear personal protective equipment. Fragments of
  workpiece or of a broken accessory may fly away and cause injury beyond immediate area of operation.

• Hold the power tool by insulated gripping surfaces only, when performing an operation 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.

• 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 accessory.

• 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.

• 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 the 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 these materials.

• Do not use accessories that require liquid cool- ants. 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, 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 firm 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

• Maintain a firm 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. Kick- back 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.

Safety guidelines during power tool operation

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 designed for the selected wheel. Wheels for which the power tool was not designed cannot be adequately guarded and are unsafe

• 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 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 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 flanges support the wheel thus reducing the possibility of wheel breakage Flanges for cut-off wheels may be different from grinding wheel flanges.

• Do not use worn down wheels from larger power tools. Wheel intended for larger power tool is not suit- able for the higher speed of a smaller tool and may burst.

• When using cymbal-shaped grinding wheel, you should ensure glass fiber reinforced plastic grind- ing wheel is used only.

• Principal axis, flange (especially the mounting surface) or lock nut shall not be damaged to avoid fracture of grinding wheel.

• Before the switch is turned on, you should en- sure the grinding wheel is not in touch with the workpiece.

• Before the tool comes into use, you should let the tool run for a while. Please note that vibration or swing may indicate poor installation or imbalance of the grinding wheel.

• Grinding shall be carried out on designated sur- face of the grinding wheel.

• Attention should be paid to the flying sparks. When holding the tool, you should avoid sparks’ flying to you or other people or combustible.

• The tool shall not be left alone during operation.
  You should operate the tool only when you hold it.

• You shall not touch the workpiece immediately after operation considering that it might be very hot and cause skin burns.

• Before the tool is used for any operation, you should switch off the tool, pull out the power plug or take out the battery box.

• Please follow instructions of the manufacturer for proper installation and use of the grinding wheel. Please be careful to handle and store the grind- ing wheel.

• Do not use separate release casings or adapters to fit the large hole grinding wheel.

• Please use the flange specified for the tool.

• With respect to the tool used for installing threaded hole grinding wheel, please ensure thread in the grinding wheel is long enough and
  could match the length of principal axis.

• Check and ensure that the workpiece is properly supported.

• Please note that, after cutting off power supply of the tool, the grinding wheel will continue to rotate.

• Please use short circuit breaker (30mA) to en- sure safety of the operator when it is very hot and moist in the workplace or you are seriously polluted by conductive dust.

• Do not use the tool on any material containing asbestos.

• Do not use water or grinding fluid.

• Please ensure that the ventilation opening is clean when working in dusty environment. If the dirt must be removed, please cut off the power of the tool (with non-metal article) to avoid damage to internal parts.

Additional safety instructions for cutting-off operations

• Do not position your body in line with and be- hind 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
• If the power supply suddenly cuts during operation, immediately move on / off switch into off in order to prevent accidental starting of the power tool
• Slow the rotation of the accessories caused by inertia down with the help of spindle lock or applying force to the side surface of discs is strictly forbidden Using spindle lock for this purpose will put the power tool out of operation and void the warranty

⚠ Warning: the chemical substances contained in dust generated in sanding, cutting, sawing, grinding, drilling and other construction industry activities may result in cancer, congenital deficiency or be harmful to the fertility. The ion of some chemical sub- stances shall be:

• Before any repair and replacement work to the ma- chine, the power plug must be pulled out firstly.
• The transparent two silicon oxide and other masonry products in the wall bricks and cement; the chromium arsenic (CCA) in wood with chemical treatment. The harm degree of these substances shall depend on the frequent degree of you carrying out these works. If you want to reduce the contact with these chemical sub- stances, please work in the place with ventilation and you shall use the appliances with safety certificates (such as the dust mask designed with tiny dust filter).
  Notice the power voltage: in power connection, you must confirm that if the power voltage is the same to the voltage marked in the tool’s data plate. If the power voltage is higher than the appropriate voltage, the accidents will be resulted to the operators, and at the same time, the tool will be destroyed. Therefore, if the power voltage has not been confirmed, then you shall never plug in arbitrarily. On the contrary, when the power voltage is lower than the required voltage, the motor will be damaged.

Recommendations on the power tool operation

Cutting (see fig. 11)

• Install cutting disc as described below

• Start the power tool, wait until the engine gains its maximum speed and only after that, smoothly bring cutting disc to the surface processed

• Do not apply excessive pressure to the power tool, as it will not bring better results but it will overload the engine and wear out cutting disc faster

• Move the power tool along the cutting line with moderate feed, not distorting and not making vibrating and bursting movements

• Cutting should be implemented in the direction shown on fig. 11. When cutting in the reverse direction the danger of uncontrolled throwing of the power tool out to the side of the operator, which can lead to serious injuries appears
  Grinding (see fig. 12)

• Install grinding disc as described above · Start the power tool, wait until the engine gains its maximum speed and only after that smoothly bring grinding disc to the surface processed

• Holding the power tool at an angle of 10° to 15° relating to the surface processed (see fig. 12) is recommended If this angle is less than recommended, it will make controlling the power tool more difficult. If this angle is more than recommended, the processing quality will decrease and grooves will be left on the billet surface

• Make alternate-reciprocal movements applying moderate pressure to the power tool Excessive pressure will not bring better results but it will overload the engine and create the danger of destruction of grinding disc, which can cause severe injuries

Power tool maintenance / preventive measures

Before carrying out any works on the power tool remove the battery 11.
Cleaning filter (see fig. 13)

Regularly inspect filter 12 (its contamination depends on the state of the environment). Clean the filter 12 as it gets dirty. Attention: do not use power tools without a filter 12.

• Remove filter 12 as shown onto fig. 13.1.
• Clean filter 12 with soft brush or blow it with compressed air.
• Install filter 12 as shown onto fig. 13.2.

Battery maintenance instruction

• Charge timely before the battery 11 is completely exhausted. Stop operation in low power and charge it immediately.
• Do not overcharge when the battery 11 is full, other- wise it will shorten the life time.
• Charge battery 11 in the room temperature of 10°C to 40°C (50°F to 104°F).
• Charge battery 11 every 6 months without operation for a long time.
• Replace worn out batteries in time. Decline of pro- duction or a significantly shorter runtime of the power tool after charging indicates aging of the battery 11 and the need for replacement.
