How to Use a Husqvarna Concrete Saw

Tools and Materials You’ll Need

Before starting, gather the following:

  • A Husqvarna concrete saw (appropriate for your job size)

  • Diamond-tipped or abrasive cutting blade

  • Personal protective equipment (PPE) – safety glasses, gloves, hearing protection, dust mask

  • Water source (for wet cutting) or dust control system (for dry cutting)

  • Chalk line or straightedge guide

  • Fuel or fully charged battery (depending on saw type)

  • Wrenches or blade change tool (included with most saws)


Step 1: Inspect the Saw and Blade

Safety starts with preparation. Inspect your Husqvarna concrete saw before every use:

  • Check for visible damage, cracks, or wear

  • Ensure all bolts and parts are tight

  • Verify the air filter and spark plug (for gas models) are clean

  • Make sure the water supply (wet saw) or vacuum (dry saw) is properly attached

Next, inspect your cutting blade:

  • Ensure it's compatible with your saw and material type

  • Look for signs of warping, missing segments, or uneven wear

  • Mount the blade according to the direction of rotation indicated on the blade and saw

Pro Tip: Always use a genuine Husqvarna diamond blade for optimal performance and longevity.


Step 2: Mark Your Cutting Line

Accurate cuts start with accurate markings.

  • Use a chalk line or pencil to draw a straight, clear cutting guide

  • If working on a large surface like a slab, snap multiple lines to section your cuts

  • For expansion joints, make sure to follow the engineer's or builder’s specifications

This step is crucial for minimizing errors and wasted material.


Step 3: Set Up Your Work Area

Create a safe and organized workspace:

  • Clear debris or loose objects from the cutting area

  • Use barriers or warning tape to keep bystanders away

  • Ensure good ventilation if cutting indoors

  • Position your saw’s water hose or vacuum system to minimize airborne dust

Using a wet cutting setup reduces dust, keeps the blade cool, and extends its life.


Step 4: Power Up and Test the Saw

Depending on your saw type, follow the right startup procedure:

  • Gas-powered models (like the K770):

    • Fill the tank with a proper fuel mix

    • Engage the choke and pull-start the engine

    • Allow the engine to warm up

  • Electric saws (like the K4000):

    • Connect to a GFCI-protected outlet

    • Power on and check blade rotation

  • Battery-powered saws (like the K1 PACE):

    • Ensure battery is fully charged

    • Lock the battery in place and press the power button

Once powered, let the saw run briefly at idle to ensure everything is working smoothly before engaging the blade with the concrete.


Step 5: Start Cutting

Now you’re ready to begin the actual cutting.

Handheld Husqvarna Concrete Saw (e.g., K770):

  • Hold the saw firmly with both hands

  • Lower the spinning blade gently into the marked line

  • Let the saw's weight do the work—avoid forcing the blade

  • Move steadily along the guide line

Walk-Behind Saw (e.g., FS 520):

  • Line up the blade with your chalk line

  • Start the engine and lower the blade slowly

  • Walk at a steady pace—too fast can damage the blade, too slow can overheat it

  • Adjust depth gradually for deeper cuts (score first, then return for a deeper pass)

Always monitor the blade temperature and make cooling cuts if needed.


Step 6: Post-Cutting Safety and Cleanup

After completing your cut:

  • Turn off the saw and allow the blade to come to a full stop

  • Disconnect the power or remove the battery

  • Allow the machine to cool down

  • Use a broom or vacuum to clear slurry or dust

  • Remove the blade if necessary and store it in a dry, cool place

Regular cleanup ensures longevity for your saw and creates a safer workspace.


Common Mistakes to Avoid

Even seasoned pros can slip up. Watch out for these pitfalls:

  • Using the wrong blade for the material (e.g., using an asphalt blade on reinforced concrete)

  • Forcing the blade instead of letting the saw work naturally

  • Skipping water during wet cuts, which leads to overheating

  • Cutting too deep in a single pass—multiple shallow cuts are safer and cleaner

  • Neglecting PPE which increases your risk of injury


Tips for Better Results

  • Replace or rotate blades regularly to ensure even wear

  • Always match blade type to the material (wet/dry, reinforced/unreinforced)

  • Use blade guards and blade depth guides provided with the saw

  • If the blade is glazing over, make a few cuts in abrasive material (like soft brick) to restore sharpness


Final Thoughts

Mastering how to use a Husqvarna concrete saw isn’t just about pushing a blade through concrete—it’s about understanding your equipment, respecting safety procedures, and executing with precision. Whether you’re making decorative cuts, expansion joints, or cutting through a slab, following the correct steps will ensure clean results and a longer lifespan for your tools.

Husqvarna’s range of concrete saws—from the compact K770 to the heavy-duty FS walk-behind series—offers a perfect fit for every job. With the right knowledge and proper technique, you’ll be cutting like a pro in no time.
