2. General Safety Information

WARNING: Read all safety warnings, instructions, illustrations, and specifications provided with this power tool. Failure to follow all instructions listed below may result in electric shock, fire, and/or serious injury.

2.1 Work Area Safety

• Keep the work area clean and well-lit. Cluttered or dark areas invite accidents.
• Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust. Power tools create sparks which may ignite the dust or fumes.
• Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

2.2 Electrical Safety

• Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges, and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
• Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.

2.3 Personal Safety

• Always wear eye protection. Use safety glasses or goggles.
• Wear hearing protection when operating the saw.
• Dress properly. Do not wear loose clothing or jewelry. Keep your hair and clothing away from moving parts.
• Stay alert, watch what you are doing, and use common sense when operating a power tool.
• Do not overreach. Keep proper footing and balance at all times.

2.4 Circular Saw Specific Safety

• Hold the power tool by insulated gripping surfaces when performing an operation where the cutting accessory may contact hidden wiring.
• 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 makes it unstable and may lead to loss of control.
• Always use the correct blade for the material being cut. Ensure the blade is sharp and free from damage.
• Be aware of sparks and hot metal chips when cutting metal. Ensure no flammable materials are nearby.
• Never attempt to cut material that is too thick for the saw's capacity.

4. Setup

4.1 Battery Installation

1. Ensure the saw is turned off and the trigger is locked.
2. Align the battery pack with the battery port on the saw.
3. Slide the battery pack into the port until it clicks securely into place.
4. To remove, press the release button on the battery pack and slide it out.

Note: This tool is sold as 'tool-only' and requires a Milwaukee M18 Lithium-Ion battery (not included) for operation.

4.2 Blade Installation and Removal

WARNING: Always disconnect the battery pack before changing or adjusting accessories.

1. Place the saw on a flat, stable surface.
2. Locate the blade arbor lock button. Press and hold it to prevent the blade from rotating.
3. Using the appropriate wrench (usually included), loosen the arbor nut by turning it counter-clockwise.
4. Remove the outer washer and the old blade.
5. Clean any debris from the arbor and washers.
6. Place the new blade onto the arbor, ensuring the teeth are pointing in the direction of rotation indicated on the saw.
7. Replace the outer washer and arbor nut. Tighten the arbor nut securely by turning it clockwise while holding the arbor lock button. Do not overtighten.
8. Release the arbor lock button and check that the blade rotates freely.

4.3 Adjusting Cutting Depth

1. Loosen the depth adjustment lever.
2. Raise or lower the saw base to achieve the desired cutting depth. The blade should extend approximately 1/8 inch (3 mm) below the workpiece.
3. Tighten the depth adjustment lever firmly to secure the setting.

5. Operating Instructions

5.1 Preparing for Operation

• Ensure the workpiece is securely clamped to prevent movement during cutting.
• Mark your cut line clearly on the material.
• Verify that the blade is appropriate for the material and securely installed.
• Wear all recommended personal protective equipment (PPE), including eye protection, hearing protection, and gloves.

5.2 Making a Cut

1. Hold the saw firmly with both hands, maintaining a balanced stance.
2. Place the front edge of the saw's base plate on the workpiece, ensuring the blade is not touching the material.
3. Engage the trigger to start the saw, allowing the blade to reach full speed before beginning the cut.
4. Slowly guide the saw into the workpiece along your marked cut line. Maintain a steady, consistent feed rate. Do not force the saw.
5. As the cut progresses, the lower blade guard will retract automatically. Ensure it closes properly after the cut is complete.
6. Once the cut is finished, release the trigger and allow the blade to stop completely before lifting the saw from the workpiece.

5.3 Tips for Metal Cutting

• Use a cutting fluid or wax when appropriate for the metal type to extend blade life and improve cut quality.
• Be aware that metal cutting generates significant heat and sparks. Ensure proper ventilation and clear the area of flammable materials.
• Allow the saw to cool down during prolonged use to prevent overheating.
• The integrated chip collector helps manage metal debris, but some chips may still be ejected.

6. Maintenance

WARNING: Always remove the battery pack before performing any maintenance.

6.1 Cleaning

• Regularly clean the saw's ventilation openings to prevent motor overheating. Use compressed air if available.
• Wipe down the tool with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners.
• Empty the chip collector frequently to maintain efficient operation and prevent buildup.

6.2 Blade Care

• Inspect the blade before each use for sharpness, cracks, or missing teeth. Replace damaged blades immediately.
• Ensure the blade is clean and free of resin or metal buildup.

6.3 Storage

• Store the saw in a dry, secure location out of reach of children.
• Remove the battery pack before storing for extended periods.
