coins, keys, nails, screws, or other small metal objects that can make a connection from one terminal to another. Shorting the battery terminals 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, 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, il- lustrations 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 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 accesso- ries 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 con- trol.
•Do not use a damaged accessory. Before each use inspect the accessory such as abra- sive 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 your- self 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. De- pending on application, use face shield, safe- ty 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 hear- ing 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 hid- den wiring. Contact with a “live” wire will also make exposed metal parts of the power tool “live” and could give the operator an electric shock.
•Never lay the power tool down until the acces- sory has come to a complete stop. The spin- ning 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.
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 kick- back forces, if proper precautions are taken.
•Never place your hand near the rotating acces- sory. 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 snag- ging 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 fre- quent kickback 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 designed for the selected wheel. Wheels for which the power tool was not designed cannot be adequately guarded and are unsafe.
•Wheels must be used only for recommend- ed 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 suitable for the higher speed of a small- er tool and may burst.
Additional Safety Warnings Specific for Abra- sive Cutting-Off Operations:
•Do not “jam” the cut-off wheel or apply exces- sive pressure. Do not attempt to make an ex- cessive depth of cut. Overstressing the wheel increases the loading and susceptibility to twist- ing or binding of the wheel in the cut and the pos- sibility 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 spin- ning 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 cor- rective 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 reenter 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 kick- back. 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, elec- trical wiring or objects that can cause kickback.
SafetyWarningsSpecificforSandingOperations:
•Do not use excessively oversized sanding disc paper. Follow manufacturers recommen- dations, 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.
SafetyWarningsSpecificforPolishingOperations:
•Do not allow any loose portion of the polish- ing bonnet or its attachment strings to spin freely. Tuck away or trim any loose attach- ment strings. Loose and spinning attachment strings can entangle your fingers or snag on the workpiece.
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. 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 work load and centrifugal forces.
Additional Safety Warnings
•The arbour size of wheels, sanding drum or any other accessory must properly fit the spindle or collet of the power tool. Accessories that do not match the mounting hardware of the power tool will run out of balance, vibrate exces- sively and may cause loss of control.
•Mandrel mounted wheels, sanding drums, cutters or other accessories must be fully inserted into the collet or chuck. The “over- hang” or the length of the mandrel from the wheel to the collet must be minimal. If the mandrel is insufficiently held and/or the overhang of the wheel is too long, the mounted wheel may become loose and ejected at high velocity.
•After changing the bits or making any adjust- ments, make sure the collet nut, chuck or any other adjustment devices are securely tight- ened. Loose adjustment devices can unexpect- edly shift, causing loss of control, loose rotating components will be violently thrown.
•Always feed the bit into the material in the same direction as the cutting edge is exiting from the material (which is the same direction as the chips are thrown). Feeding the tool in the wrong direction causes the cutting edge of the bit to climb out of the work and pull the tool in the direction of this feed.
•When using steel saws, cut-off wheels, high speed cutters or tungsten carbide cutters, al- ways have the work securely clamped. These wheels will grab if they become slightly canted
