44. Never hold piece being cut in your hands oracross your leg. Secure the workpiece to astable platform. It is important to support the workproperly to minimize body exposure, blade binding,or loss of control.A typical illustration of proper hand support, workpiecesupport, and supply cord routing (if applicable).0001575. Hold the power tool by insulated grippingsurfaces only, when performing an operationwhere the cutting tool may contact hiddenwiring or its own cord. Contact with a "live" wirewill also make exposed metal parts of the powertool "live" and could give the operator an electricshock.6. When ripping, always use a rip fence orstraight edge guide. This improves the accuracyof cut and reduces the chance of blade binding.7. Always use blades with correct size and shape(diamond versus round) of arbour holes.Blades that do not match the mounting hardwareof the saw will run eccentrically, causing loss ofcontrol.8. Never use damaged or incorrect bladewashers or bolt. The blade washers and boltwere specially designed for your saw, for optimumperformance and safety of operation.9. Kickback causes and related warningsí kickback is a sudden reaction to a pinched,bound or misaligned saw blade, causing anuncontrolled saw to lift up and out of theworkpiece toward the operator;í when the blade is pinched or bound tightly bythe kerf closing down, the blade stalls and themotor reaction drives the unit rapidly backtoward the operator;í if the blade becomes twisted or misaligned inthe cut, the teeth at the back edge of theblade can dig into the top surface of the woodcausing the blade to climb out of the kerf andjump back toward the operator.Kickback is the result of saw misuse and/orincorrect operating procedures or conditions andcan be avoided by taking proper precautions asgiven below.• Maintain a firm grip with both hands on thesaw and position your arms to resistkickback forces. Position your body toeither side of the blade, but not in line withthe blade. Kickback could cause the saw tojump backwards, but kickback forces can becontrolled by the operator, if properprecautions are taken.• When blade is binding, or when interruptinga cut for any reason, release the trigger andhold the saw motionless in the materialuntil the blade comes to a complete stop.Never attempt to remove the saw from thework or pull the saw backward while theblade is in motion or kickback may occur.Investigate and take corrective actions toeliminate the cause of blade binding.• When restarting a saw in the workpiece,centre the saw blade in the kerf and checkthat saw teeth are not engaged into thematerial. If saw blade is binding, it may walkup or kickback from the workpiece as the sawis restarted.• Support large panels to minimise the riskof blade pinching and kickback. Largepanels tend to sag under their own weight.Supports must be placed under the panel onboth sides, near the line of cut and near theedge of the panel.To avoid kickback, do supportboard or panel near the cut.000154
