If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools. Keep cutting tools sharp and clean.f. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control. Use the power tool, accessories and g. blades etc. in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation. Service5. Have your power tool serviced by a a. qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained. Circular Saw Safety Warnings 1. DANGER: Keep hands away from cutting area and the blade. Keep your second hand on auxiliary handle, or motor housing. If both hands are holding the saw, they cannot be cut by the blade. Do not reach underneath the 2. workpiece. The guard cannot protect you from the blade below the workpiece. Adjust the cutting depth to the 3. thickness of the workpiece. Less than a full tooth of the blade teeth should be visible below the workpiece. Never hold piece being cut in your 4. hands or across your leg. Secure the workpiece to a stable platform. It is important to support the work properly to minimize body exposure, blade binding, or loss of control. Hold power tool by insulated gripping 5. surfaces when performing an operation where the cutting tool may contact hidden wiring or its own cord. Contact with a. live. wire will also make exposed metal parts of the power tool . live. and shock the operator. When ripping always use a rip fence 6. or straight edge guide. This improves the accuracy of cut and reduces the chance of blade binding. Always use blades with correct size 7. and shape (diamond versus round) of arbor holes. Blades that do not match the mounting hardware of the saw will run eccentrically, causing loss of control. Never use damaged or incorrect blade 8. washers or bolt. The blade washers and bolt were specially designed for your saw, for optimum performance and safety of operation. Causes and Operator Prevention of 9. Kickback: Kickback is a sudden reaction to a • pinched, bound or misaligned saw blade, causing an uncontrolled saw to lift up and out of the workpiece toward the operator; When the blade is pinched or bound • tightly by the kerf closing down, the blade stalls and the motor reaction 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 the top surface of the wood causing the blade to climb out of the kerf and jump back toward the operator. Kickback is the result of saw misuse and/or incorrect operating procedures or conditions and can be avoided by taking proper precautions as given below: Maintain a firm grip with both hands a. on the saw and position your arms to resist kickback forces. Position your body to either side of the blade, but not in line with the blade. Kickback could cause the saw to jump backwards, but kickback forces can be controlled by the operator, if proper precautions are taken. When blade is binding, or when b. interrupting a cut for any reason, release the trigger and hold the saw motionless in the material until the blade comes to a complete stop. Never attempt to remove the saw from the work or pull the saw backward while the blade is in motion or kickback may occur. Investigate and take corrective actions to eliminate the cause of blade binding. When restarting a saw in the c. workpiece, center the saw blade in the kerf and check that saw teeth are not engaged into the material. If saw blade is binding, it may walk up or kickback from the workpiece as the saw is restarted. Support large panels to minimize the d. risk of blade pinching and kickback. Large panels tend to sag under their own weight. Supports must be placed under the panel on both sides, near the line of cut and near the edge of the panel. Do not use dull or damaged blades.e. Unsharpened or improperly set blades produce narrow kerf causing excessive friction, blade binding and kickback. Blade depth and bevel adjusting f. locking levers must be tight and secure before making cut. If blade adjustment shifts while cutting, it may cause binding and kickback. Use extra caution when making a g. .plunge cut. into existing walls or other blind areas. The protruding blade may cut objects that can cause kickback. Check lower guard for proper closing 10. before each use. Do not operate the saw if lower guard does not move freely and close instantly. Never clamp or tie the lower guard into the open position. If saw is accidentally dropped, lower guard may be bent. Raise the lower guard with the retracting handle and make sure it moves freely and does not touch the blade or any other part, in all angles and depths of cut. Check the operation of the lower 11. guard spring. If the gu...
