•Use power tools only with specifically desig- nated battery packs. Use of any other battery packs may create a risk of injury and fire.

•When battery pack is not in use, keep it away from other metal objects like paper clips, coins, keys, nails, screws, or other small metal objects that can make a connection from one terminal to another. Shorting the battery termi- nals together may cause burns or a fire.

•Under abusive conditions, liquid may be eject- ed from the battery, avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.

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.

SPECIFIC SAFETY RULES

Safety Warnings Common for Grinding, Sand- ing, Wire Brushing or Abrasive Cutting-Off Operations:

•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.

•Operations such as polishing are not recom- mended to be performed with this power tool. Operations for which the power tool was not de- signed may create a hazard and cause personal injury.

•Do not use accessories which are not specifi- cally 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 hard- ware 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 acces- sory 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 acces- sories 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 work shop 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.

•HHold power tool by insulated gripping surfac- es only, when performing an operation where the cutting accessory may contact hidden wir- ing or its own 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 acces- sory. 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 acces- sory 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 coolants. 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.
