SPECIFIC LES FOR DIE GRINDERS

Safety Warnings Common for Grinding. Sanding, Wire Brushing, Polishing. Carving or Abrasive Cutting-OH Operations:

• This power tool is intended to function as a grinder, sander, wire brush, polisher, carving or cutoff tool. Read all safety warnings, instructions, illustrations and specifications provided with this power tool. Failure to follow as instructions haled below may result in electric shock, fire andior serous 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 grinding accessories must be at least equal to the maximum speed marked on the power tool. Grinding 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 controlled.

• The arbour size of wheels, sanding drum or any other accessory must properly fit the spindle or collect of the power tool. Accessories that do not match the flaunting hardware of the power tool MI run out of balance. vibrate excessively and may cause toss of control

• Mandrel mounted wheels, sanding drums, cutters or other accessories must be fully Inserted into the collet or chuck. If the mandrel is insufficiently held and/or the overhang of the wheel a too long, the mounted wheel may become loose and be elected at high velouty.

• Do not use a damaged accessory. Before each use Inspect the accessory such as abrasive wheels for chips and cracks, sanding drum 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 or one minute. Damaged accessories will normally
  break apart during this test time.

• Wear personal protective equipment. Depending 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 work piece fragments. The eye protection must be capable of stopping flying debris generated by various operations. The dust mask or respirator must be capable 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 workpieces or of a broken accessory my fly away and  and cause injury beyond immediate area of operation.

• Hold power tool by insulated gripping surfaces only, when performing an operation where the cutting accessory may contact hidden wiring. Cutting accessory contacting a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock.

• Always hold the tool firmly in your hands during the  start-up. The reaction torque of the motor, as it
  accelerates to full speed, can cause the tool to twist.
  • Use clamps to support workpiece whenever practical. Never hold a small workpiece in one hand and the tool in the other hand while in use. Clamping a small workpiece allows you to use your hand(s) to control the tool. Round material such as dowel rods, pipes or tubing have a tendency to roll while being cut, and may cause the bit to bind or jump toward you.

• 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.

• After changing the bits or making any adjustments, make sure the collet nut, chuck or any other adjustment devices are securely tightened. Loose adjustment devices can unexpectedly shift, causing loss of control, loose rotating components will be violently thrown.

• 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 use accessories that require liquid coolants t 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, sanding band, 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. 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. The operator can control kickback forces, if proper precautions are taken.

• 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 toothed saw blade. Such blades create frequent kickback and loss of control.

• 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 rotary files cut-off wheels high speed cutters or tungsten carbide cutters, always have the work securely clamped. These wheels will grab if they become slightly canted in the groove, and can kickback.

Safety Warnings Specific for Grinding and Abrasive Cutting-Off Operations:

• Use only wheel types that are recommended for your power tool and only for recommended applications. For example: do not grind with the side of a cut-off wheel. Abrasive cut-off wheels are intended for peripheral grinding. side forces applied to these wheels may cause them to shatter.

• For threaded abrasive cones and plugs use only undamaged wheel mandrels with an unrelieved shoulder flange that are of correct size and length. Proper mandrels will reduce the possibility of breakage. “Do not “Jam” a 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 snagging of the wheel in the cut and the possibility of kickback or wheel breakage. “Do not position your hand in line with and behind the rotating wheel. When the wheel, at the point of operation, is moving away from your hand, the pos-sible kickback may propel the spinning wheel and the power tool directly at you.

• When wheel Is pinched, snagged or when inter-rupting 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 work-piece. 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 oversize workpiece to minimize the risk of wheel piing and kickback. Large workpieces tend o 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 pro-truding wheel may cut gas or water pipes, electrical wiring or objects that can cause kickback. Safety Warnings Specific for Wire Brushing Op-erations:

• Be aware that wire bristles arc 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.

• Allow brushes to run at operating speed for at least one minute before using them. During this time no one is to stand in front or in line with the brush. Loose bristles or wires will be discharged during the run-in time.

• Direct the discharge of the spinning wire brush away from you. Small particles and tiny wire frag-ments may be discharged at high velocity during the use of these brushes and may become imbedded in your skin. Additional Safety Warnings
  Warnings
