Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock. If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can reduce dustrelated hazards. When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock. 5 POWER TOOL SAFETY Power tool use and care Use clamps or another practical way to secure and support the workpiece to a stable platform. Holding the work by hand or against your body leaves it unstable and may lead to loss of control. Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed. Battery tool use and care Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired. Recharge only with the charger specified by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack. Disconnect the plug from the power source and/or the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally. Use power tools only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire. Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users. When battery pack is not in use, keep it away from other metal objects, like paper clips, coins, keys, nails, screws or other small metal objects that can make a connection from one terminal to another. Shorting the battery terminals together may cause burns or a fire. Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tool’s operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools. Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns. Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control. Service Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained. Use the power tool, accessories and tool bits 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. Hold power tool by insulated gripping surfaces when performing an operation where the cutting tool may contact hidden wiring or its own cord. Contact with a "live" wire will make exposed metal parts of the tool "live" and shock the operator. SAVE THESE INSTRUCTIONS FOR REFERENCE 6 SPECIFIC SAFETY RULES ! WARNING: Know your circular saw. Do not plug the charger into the power source or install a battery in the tool until you have read and understand this Instruction Manual. Learn the tool’s applications and limitations, as well as the specific potential hazards related to this tool. Following this rule will reduce the risk of electric shock, fire, or serious injury. Hold power tool by insulated gripping 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 straight edge guide. This improves the accuracy of cut and reduces the chance of the blade binding. Always wear eye protection. Any power tool can throw foreign objects into your eyes and cause permanent eye damage. ALWAYS wear safety goggles (not glasses) that comply with ANSI safety standard Z87.1. Everyday glasses have only impact resistant lenses. They ARE NOT safety glasses. Always use blades with correct size 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 washers or bolt. The blade washers and bolt were specially designed for your saw, for optimum performance and safety of operation. ! WARNING: Glasses or goggles not in compliance with ANSI Z87.1 could cause serious injury when they break. CAUSES AND OPERATOR PREVENTION OF KICKBACK Always keep hands out of the path of the saw blade. Avoid awkward hand positions where a sudden slip could cause your hand to move into the path of the saw blade. 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; ! DANGER: Keep hands away from cutting area and the blade. Keep your second hand on the tool. If both hands are holding the saw, they cannot be cut by the blade. 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. Do not reach underneath the workpiece. The guard cannot protect you from the blade below the workpiece. 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: Adjust the cutting depth according to the thickness of the workpiece. Less than a full tooth of the blade teeth should be visible below the workpiece or approximately 3/8" (10 mm). Never hold piece being cut in your 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. Maintain a firm grip with both hands on the saw and position your arms to resist kickback forces. Position your body to the left or right 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. 7 SPECIFIC SAFETY RULES CAUSES AND OPERATOR PREVENTION OF KICKBACK – cont’d Check the operation of the lower guard spring. If the guard and the spring are not operating properly, they must be serviced before use. The lower guard may operate sluggishly due to damaged parts, gummy deposits, or a build-up of debris. When 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. The lower guard should be retracted manually only for special cuts such as "plunge cuts" and "compound cuts". Raise lower guard by retracting handle and as soon as the blade enters the material, the lower guard must be released. For all other sawing, the lower guard should operate automatically. When restarting a saw in the workpiece, center the saw blade in the kerf and check that saw teeth are not engaged into the material. If the saw blades are binding, it may walk up or kickback from the workpiece as the saw is restarted. Always observe that the lower guard is covering the blade before placing saw down on the bench or on the floor. An unprotected, coasting blade will cause the saw to walk backwards, cutting whatever is in its path. Be aware of the time it takes for the blade to stop after the switch is released. Support large panels to minimize 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. Never operate the saw while it is being carried to another location. The blade guard may be open and potentially cause serious injury. Do not use dull or damaged blades. Unsharpened or improperly set blades produce narrow kerf causing excessive friction, blade binding and kickback. If the switch fails to turn the saw ON or OFF properly, stop using it immediately and have the saw switch repaired. ADDITIONAL SPECIFIC SAFETY RULES Always allow the saw to reach full speed before beginning the cut. 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. Never use the side of the blade for cutting. When making horizontal cuts, make sure the weight of the tool is not forcing the side of the blade to do the cutting. This will reduce the risk of kickback. Check the lower guard for proper closing before each use. Do not operate the saw if the lower guard does not move freely and close instantly. Never clamp or tie the lower guard into the open position. If the saw is accidentally dropped, the lower guard may be damaged. 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 depths of cuts. Make sure there are no nails or foreign objects in the area of the workpiece to be cut. Never lay workpiece on hard surfaces like concrete, stone, etc. The protruding blade may cause tool to jump. ! DANGER: To avoid injury from accidental starting, always remove the plug from the power source before making any adjustments and before installing or removing a saw blade. 8 SPECIFIC SAFETY RULES ADDITIONAL SPECIFIC SAFETY RULES – cont’d When replacing the blade, make sure the replacement blade is 5½" (14 cm) in diameter and is rated for at least 3,800 RPM. Installing an incorrect blade will result in possible injury and poor cutting action. After changing a blade or making adjustments, make sure the blade clamp screw is securely tightened. Loose blades and adjustment devices will be violently thrown. Never touch the blade during or immediately after use. After use the blade is too hot to be safely touched with bare hands. ! DANGER: Always remove the battery when changing the blade. SAVE THESE INSTRUCTIONS FOR REFERENCE 9 BATTERY & CHARGER SAFETY !

MATERIALS THAT YOU CAN CUT The circular saw is a versatile saw that allows you to cut many different types of materials. Some of the materials include: ● Wood products such as lumber, hardwood, plywood, composit board and panelling ● Drywall ● Masonite and plastic NOTE: To align the saw blade with the cutting mark, use the guide marks on the front of the sole plate (Fig. 11) and the laser line. Use the 0° cutting mark (1) for right angle cuts. Use only the 45° mark (2) for 45° cuts. The 45° mark will allow for the extra material needed for the angle cut. Always make a test cut on a scrap workpiece before cutting the new material. NOTE: There are several different types of blades available. Generally, blades with carbidetipped teeth cut better and stay sharp longer. Tooth count and configuration are also important. High tooth counts cut slower, and are best suited for making smooth cuts on thinner materials such as panelling. Use the correct blade for your application. GENERAL CUTTING 1. Make any adjustments to the saw before installing the battery. Adjustments include cutting depth, cutting angle and rip guide (if installed). 2. Clearly mark the workpiece to locate the position of the cut. 3. Hold a smaller workpiece with a vise. Clamp a larger workpiece to a workbench or table. Fig. 11 17 ASSEMBLY AND OPERATING GENERAL CUTTING – cont’d ! WARNING: Do not force the circular saw. Use only enough force to keep the blade cutting at full speed. Excessive pressure on the blade will cause it to slow down and overheat, resulting in poor cut quality and damage to the motor. RIP GUIDE CUTTING 1. Set the rip guide foot at the required width (Fig. 9). NOTE: When starting the cut, make sure the blade is parallel to the edge of the workpiece and the rip guide foot is against the edge of the workpiece. 2. Proceed with the cut as outlined in "GENERAL CUTTING" above. NOTE: As you move the saw through the workpiece, make sure the guide foot stays in contact with the workpiece. 18 MAINTENANCE !
