Safety instructions for cut-off machines

1. Cut-off machine safety warnings

   • a) Position yourself and bystanders away from the plane of the rotating wheel. The guard helps to protect the operalor from broken wheel fragments and accidental contact with the wheel

   • b) Use only bonded reinforced or diamond cut-off wheels for your power tool. Just because an accessory can be attached to your power tool, it does not assure safe operation.

   • NOTE 1 The wording “bonded reinforced” or diamond “is used as applicable depending on the designation of the tool.

   • c) 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.

   • d) Wheels must be used 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.

   • e) Always use undamaged wheel flanges that are of the correct diameter for your selected wheel
     Proper wheel flanges support the wheel thus reducing the possibility of wheel breakage.

   • f) The outside diameter and the thickness of your accessory must be within the capacity rating ot your power tool. incorrectly sized accessories cannot be adequately guarded or controlled.

   • g) The arbor size of wheels and flanges must properly fit the spindle of the power tool.

   • Wheels and flanges with arbor 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.

   • h) Do not use damaged wheels. Before each use, inspect the wheels for chips and cracks. If the power tool or wheel is dropped, inspect for damage or install an undamaged wheel. After inspecting and installing the wheel, position yourself and bystanders away from the plane of the rotating wheel and run the power tool at maximum no-load speed for one minute. Damaged wheels will normally break apart during this test time.

   • i) 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 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.

   • j) Keep bystanders a safe distance away from the work area. Anyone entering the work area must wear personal protective equipment. Fragments of workpiece or a broken wheel may fly away and cause injury beyond the immediate area of operation.

   • k) 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 wheel.

   • l) Regularly clean the power tool’s air vents. The motor’s fan can draw dust inside the housing and excessive accumulation of powdered metal may cause electrical hazards.

   • m) Do not operate the power tool near flammable materials. Do not operate the power tool while placed on a combustible surface such as wood. Sparks could ignite these materials.

   • n) Do not use accessories that require liquid coolants. Using water or other liquid coolants may result in electrocution or shock.

   • NOTE 2 The above warning does not apply to power tools specifically designed for use with a liquid system.

2. Kickback and related warnings

   • Kickback is a sudden reaction to a pinched or snagged rotating wheel. Pinching or snagging causes rapid stalling of the rotating wheel which in turn, causes the uncontrolled cutting unit to be forced upwards toward the operator.

   • 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. 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.

   • a ) 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 upward kickback forces if proper precautions are taken.

   • b) Do not position your body in line with the rotating wheel. If kickback occurs, It will propel the cutting unit upwards toward the operator.

   • c) Do not attach a saw chain or woodcarving blade. segmented diamond wheel with a peripheral gap greater than 10 mm or toothed saw blade. Such blades create frequent kickbacks and loss of control.

   • d) Do not ” jam ” the 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 binding of the wheel in the cut and the possibility of kickback or wheel breakage.

   • e) When the wheel is binding or when interrupting a cut for any reason, switch off the power tool and hold the cutting unit motionless until the wheel comes to a complete stop. Never attempt to remove the 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.

   • f) Do not restart the cutting operation in the workpiece. Let the wheel reach full speed and carefully re-enter the cut. The wheel may bind, walk up, or kick back if the power tool is restarted in the workpiece.

   • g) Support any oversized workpiece to minimize the risk of wheel pinching and kickback. Large workpieces tend to sag under their weight. Supports must be placed under the workpiece near the line of cut and the edge of the workplace on both sides of the wheel.

UK power plug warnings:

Your product is fitted with a BS 1363-1 approved electric plug with an internal fuse approved to BS 1362. If the plug is not suitable for your socket, it should be removed and an appropriate plug should be fitted in its place by an authorized customer service agent.
