Service
►Tool service must be performed only by qualified repair personnel. Service or maintenance performed by unqualified personnel could result in a risk of injury.
►When servicing a tool, use only identical replacement parts. Use of unauthorized parts or failure to follow maintenance instructions may create a risk of electric shock or injury.
Specific Safety Rules for Circular Saws
!WARNING: Risk of personal injury.
►Keep hands away from the blade and cutting area. Keep your second hand on the auxiliary handle. If both hands are holding the saw, they cannot be cut by the blade.
►Keep your body positioned to either side of the saw blade, but not in line with the saw blade. Kickback could cause the saw to jump backward. (See “Causes and Prevention of Kickback” below.)
►Do not reach underneath the workpiece. The blade is fully exposed under the workpiece.
►Never use a dust extraction system when making cuts that can result in sparks, such as cutting through nails and other ferrous materials. Sparks and hot embers can cause a fire or explosion in the dust extraction system.
►Never hold the piece being cut in your hands or across your leg. It is important to support the work properly to minimize body exposure, blade binding, or loss of control.
►Hold the saw by the insulated handles when performing an operation in which the sawblade may contact hidden wiring or its own cord. Contact with a “live” wire will make the exposed metal parts of the tool “live” and shock the operator.
►When ripping, always use a rip fence or straight edge guide. This improves the accuracy of cut and reduces the chance for blade binding.
►Always use blades with the correct size and shape 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 flanges or bolt. The blade flanges and bolt were specially designed for your saw for optimum performance and safety of operation.
Causes and Prevention of Kickback
Kickback is a sudden reaction to a pinched, bound, or misaligned saw blade that causes 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 incorrect operating procedures or conditions and can be avoided by taking proper precautions as described below:
►Maintain a firm grip with both hands on the saw and position your body and arm to allow you to resist kickback forces. Kickback forces can be controlled by the operator if proper precautions are taken.
►If the blade is binding or when 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 workpiece, center the saw blade in the kerf and check that the saw teeth are not engaging the material. If the saw blade is binding during a restart, it may climb up or kickback from the workpiece.
►Do not use a dull or damaged blade. Dull or improperly sharpened blades cause excessive friction, blade binding, and kickback.
►Support large panels to minimize the risk of the blade pinching and causing a 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 as shown.
►The bevel adjusting knobs must be fully tightened before making a cut. If the blade tilts during a cut, it will bind and cause a kickback.
►Use extra caution when making a plunge cut into existing walls or other blind areas. The protruding blade may cut objects that can cause kickback.
Respiratory Exposure Warning
Various dust created by power sanding, sawing, grinding, drilling and other construction activities contains chemicals known (to the State of California) to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:
►lead from
►crystalline silica from bricks, cement, and other masonry products,
►arsenic and chromium from
The risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment, such as dust masks that are specially designed to filter out microscopic particles.
