45. Hold power tool by insulated grippingsurfaces when performing an operation wherethe cutting tool may contact hidden wiring.Contact with a "live" wire will also make exposedmetal parts of the power tool "live" and shock theoperator.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. Causes and Operator Prevention of Kickback:− 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;− 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;− 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 wheninterrupting a cut for any reason, releasethe trigger and hold the saw motionless inthe material until the blade comes to acomplete stop. Never attempt to removethe saw from the work or pull the sawbackward while the blade is in motion orkickback may occur. Investigate and takecorrective actions to eliminate the cause ofblade 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.011398Do not support board orpanel away from the cut.011399• Do not use dull or damaged blades.Unsharpened or improperly set bladesproduce narrow kerf causing excessive friction,blade binding and kickback.• Blade depth and bevel adjusting lockinglevers must be tight and secure beforemaking cut. If blade adjustment shifts whilecutting, it may cause binding and kickback.• Use extra caution when making a "plungecut" into existing walls or other blind areas.The protruding blade may cut objects that cancause kickback.10. Check lower guard for proper closing beforeeach use. Do not operate the saw if lowerguard does not move freely and close instantly.Never clamp or tie the lower guard into the
