2. General Safety Instructions

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 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

• Power tool plugs must match the outlet. Never modify the plug in any way.
• 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, hearing protection, and a dust mask.
• 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.

5. Setup and Assembly

5.1 Installing the Saw Blade

1. Ensure the saw is unplugged from the power source.
2. Press the spindle lock button (if present) to prevent the blade from rotating.
3. Using the provided spanner and hex key, loosen the blade retaining bolt.
4. Carefully remove the outer flange and old blade (if applicable).
5. Place the new 185mm saw blade onto the spindle, ensuring the teeth are pointing in the direction of rotation indicated by the arrow on the saw guard.
6. Replace the outer flange and tighten the blade retaining bolt securely with the spanner and hex key. Do not overtighten.
7. Release the spindle lock.

5.2 Attaching the Auxiliary Handle

The auxiliary handle provides better control and stability during operation. Attach it to the designated mounting point on the front of the saw, ensuring it is securely fastened.

5.3 Connecting the Dust-Blowing Port Adapter

For cleaner operation and improved visibility, attach the dust-blowing port adapter to the saw's dust outlet. This allows for connection to a vacuum cleaner or dust collection system.

5.4 Adjusting Cutting Depth

To adjust the cutting depth, loosen the depth adjustment lever, move the base plate up or down to the desired depth, and then securely tighten the lever. Ensure the blade extends slightly below the workpiece for a clean cut.

5.5 Adjusting Bevel Angle

For angled cuts, loosen the bevel adjustment lever, tilt the base plate to the desired angle (up to 45°), and then securely tighten the lever. The saw can achieve a maximum cutting depth of 41mm at a 45° bevel.

6. Operating Instructions

6.1 Before Starting

• Ensure the workpiece is securely clamped and stable.
• Verify the blade is sharp and appropriate for the material being cut.
• Check that all adjustments (depth, bevel) are securely locked.
• Wear appropriate personal protective equipment (PPE).

6.2 Starting and Stopping the Saw

To start the saw, press the safety lock release button and then squeeze the trigger switch. To stop, release the trigger switch. The safety lock prevents accidental starting.

6.3 Making a Cut

1. Position the front edge of the saw's base plate flat on the workpiece.
2. Align the blade with your cutting line. The integrated laser guide can assist with precise alignment.
3. Start the saw and allow the blade to reach full speed before engaging the material.
4. Slowly and steadily push the saw forward through the workpiece, maintaining firm pressure. Do not force the saw; let the blade do the work.
5. Maintain a clear line of sight to the cutting path. The dust-blowing feature and oversized vents help keep the cutting line visible and prevent motor overheating.
6. Once the cut is complete, release the trigger and allow the blade to stop completely before lifting the saw from the workpiece.

6.4 Using the Guide Ruler

Insert the guide ruler into the slot on the saw's base plate. Adjust it to the desired distance from the blade and tighten the locking screw. This allows for consistent, straight cuts parallel to the edge of the workpiece.
