CIRCULAR SAW SAFETY WARNINGS Kickback is the result of saw misuse and/or incorrect operat- Always observe that the lower guard is covering the ing procedures or conditions and can be avoided by taking blade before placing the saw down on bench or floor. proper precautions as given below: An unprotected, coasting blade will cause the saw to walk Maintain a firm grip with both hands on the saw and position your arms to resist kickback forces. Position backwards, cutting whatever is in its path. Be aware of the time it takes for the blade to stop after switch is released. 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 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, centre the saw blade in the kerf and check that saw teeth are not engaged into the material. If a saw blade binds, it may walk up or kickback from the workpiece as the saw is restarted. Support large panels to minimise the 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. Unsharpened or improperly set blades produce narrow kerf causing excessive friction, blade binding and kickback. Blade depth and bevel adjusting locking levers must be tight and secure before making the cut. If blade adjustment shifts while cutting, it may cause binding and kickback. Use extra caution when sawing into existing walls or other blind areas. The protruding blade may cut objects that can cause kickback. LOWER GUARD FUNCTION ADDITIONAL SAFETY WARNINGS Use clamps or other practical way to secure and support the workpiece to a stable platform. Holding the work by hand or against your body is unstable and may lead to loss of control. Always wear eye protection with side shields marked to comply with ANSI Z87.1 when assembling parts, operating the tool, or performing maintenance.

Following this rule will reduce the risk of serious personal injury. Protect your hearing. Wear hearing protection during extended periods of operation. Following this rule will reduce the risk of serious personal injury. Battery tools do not have to be plugged into an electrical outlet; therefore, they are always in operating condition. Be aware of possible hazards when not using your battery tool or when changing accessories. Following this rule will reduce the risk of electric shock, fire, or serious personal injury. Do not place battery tools or their batteries near fire or heat. This will reduce the risk of explosion and possibly injury. Do not crush, drop or damage battery pack. Do not use a battery pack or charger that has been dropped or received a sharp blow. A damaged battery is subject to explosion. Properly dispose of a dropped or damaged battery immediately. Batteries can explode in the presence of a source of ignition, such as a pilot light. To reduce the risk of serious Check lower guard for proper closing before each personal injury, never use any cordless product in the pres- use. Do not operate the saw if lower guard does not ence of open flame. An exploded battery can propel debris move freely and close instantly. Never clamp or tie the and chemicals. If exposed, flush with water immediately. 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 guard spring. If the guard and the spring are not operating properly, they must be serviced before use. Lower guard may operate sluggishly due to damaged parts, gummy deposits, or a build-up of debris. Do not charge battery tool in a damp or wet location. Do not use, store, or charge battery packs or products in locations where the temperature is less than 50°F or more than 100°F. Do not store outside or in vehicles. Under extreme usage or temperature conditions, battery leakage may occur. If liquid comes in contact with your skin, wash immediately with soap and water. If liquid gets into your eyes, flush them with clean water for at least 10 minutes, then seek immediate medical attention. Following this rule will reduce the risk of serious The lower guard may be retracted manually only for personal injury. special cuts such as "plunge cuts" and "compound cuts." Raise the lower guard by retracting handle and as soon as blade enters the material, the lower guard must be released. For all other sawing, the lower guard Save these instructions.
