7 ENGLISHCircular saw safety warningsCutting procedures1. DANGER: Keep hands away from cutting areaand the blade. Keep your second hand on auxil-iary handle, or motor housing. If both hands areholding the saw, they cannot be cut by the blade.2. Do not reach underneath the workpiece. The guardcannot protect you from the blade below the workpiece.3. Adjust the cutting depth to the thickness ofthe workpiece. Less than a full tooth of the bladeteeth should be visible below the workpiece.4. Never hold the workpiece in your hands oracross your leg while cutting. Secure theworkpiece to a stable platform. It is important tosupport the work properly to minimise body expo-sure, blade binding, or loss of control.► Fig.15. Hold the power tool by insulated grippingsurfaces, when performing an operation wherethe cutting tool may contact hidden wiring orits own cord. Contact with a "live" wire will alsomake exposed metal parts of the power tool "live"and could give the operator an electric shock.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. Bladesthat do not match the mounting hardware of thesaw will run off-centre, causing loss of control.8. Never use damaged or incorrect blade wash-ers or bolt. The blade washers and bolt werespecially designed for your saw, for optimumperformance and safety of operation.Kickback causes and related warnings— kickback is a sudden reaction to a pinched, jammed ormisaligned saw blade, causing an uncontrolled saw tolift up and out of the workpiece toward the operator;— when the blade is pinched or jammed tightly by thekerf closing down, the blade stalls and the motor reac-tion drives the unit rapidly back toward the operator;— if the blade becomes twisted or misaligned in the cut,the teeth at the back edge of the blade can dig into thetop surface of the wood causing the blade to climb outof the kerf and jump back toward the operator.Kickback is the result of saw misuse and/or incorrectoperating procedures or conditions and can be avoidedby taking proper precautions as given below.1. Maintain a firm grip with both hands on thesaw and position your arms to resist kickbackforces. Position your body to either side of theblade, but not in line with the blade. Kickbackcould cause the saw to jump backwards, butkickback forces can be controlled by the operator,if proper precautions are taken.2. When blade is binding, or when interrupting acut for any reason, release the trigger and holdthe saw motionless in the material until theblade comes to a complete stop. Never attemptto remove the saw from the work or pull the sawbackward while the blade is in motion or kick-back may occur. Investigate and take correctiveactions to eliminate the cause of blade binding.3. When restarting a saw in the workpiece, centre the sawblade in the kerf so that the saw teeth are not engagedinto the material. If a saw blade binds, it may walk up orkickback from the workpiece as the saw is restarted.4. Support large panels to minimise the risk ofblade pinching and kickback. Large panels tendto sag under their own weight. Supports must beplaced under the panel on both sides, near the lineof cut and near the edge of the panel.► Fig.2► Fig.35. Do not use dull or damaged blades. Unsharpenedor improperly set blades produce narrow kerf causingexcessive friction, blade binding and kickback.6. Blade depth and bevel adjusting locking levers must betight and secure before making the cut. If blade adjust-ment shifts while cutting, it may cause binding and kickback.7. Use extra caution when sawing into existingwalls or other blind areas. The protruding blademay cut objects that can cause kickback.8. ALWAYS hold the tool firmly with both hands.NEVER place your hand, leg or any part of yourbody under the tool base or behind the saw,especially when making cross-cuts. If kickbackoccurs, the saw could easily jump backwards overyour hand, leading to serious personal injury.► Fig.49. Never force the saw. Push the saw forward at aspeed so that the blade cuts without slowing.Forcing the saw can cause uneven cuts, loss ofaccuracy, and possible kickback.Lower guard function1. Check the lower guard for proper closingbefore each use. Do not operate the saw if thelower guard does not move freely and closeinstantly. Never clamp or tie the lower guardinto the open position. If the saw is accidentallydropped, the lower guard may be bent. Raise thelower guard with the retracting handle and makesure it moves freely and does not touch the bladeor any other part, in all angles and depths of cut.2. Check the operation of the lower guard spring. Ifthe guard and the spring are not operating prop-erly, they must be serviced before use. Lowerguard may operate sluggishly due to damaged parts,gummy deposits, or a build-up of debris.3. The lower guard may be retracted manuallyonly for special cuts such as “plunge cuts”and “compound cuts”. Raise the lower guardby the retracting handle and as soon as theblade enters the material, the lower guardmust be released. For all other sawing, the lowerguard should operate automatically.4. Always observe that the lower guard is cover-ing the blade before placing the saw down onbench or floor. An unprotected, coasting bladewill cause the saw to walk backwards, cuttingwhatever is in its path. Be aware of the time ittakes for the blade to stop after switch is released.5. To check lower guard, open lower guard by hand,then release and watch guard closure. Also checkto see that retracting handle does not touchtool housing. Leaving blade exposed is VERYDANGEROUS and can lead to serious personal injury.
