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.
