How To Troubleshoot A Concrete Saw
How To Troubleshoot A Concrete Saw: A Complete Guide


If proper maintenance is not performed on your Concrete Saw, the results can be very expensive and time-consuming. It all comes down to preventing the most frequent issues with your concrete saw at the right time.


We will guide you through a few quick maintenance tips to help you repair common concrete saw issues:

1.   Engine will not start: 

  • Emergency stop button is activated: Pull the emergency stop button. 
  • Fuel tank is empty: Verify that there is enough fuel in the tank. 
    • Note: Use octane gasoline. (We recommend Octane 87+ Gasoline).
  • Oil: Replace oil regularly to ensure longevity. We recommend to add SAE10W-30 Oil.
  • Fuel filter clogged: If the fuel filter or fuel lines are clogged, replace them.
    • Note: Change the gasoline in the gas tank. Old gasoline can clog up the carburetor, making it difficult to start the engine.
  • Check for failing battery connection: Be sure to clean and tighten battery cables
  • Main circuit breaker has fallen: Identify a short wire issue if the copper inside deteriorates and/or splits.
  • Weather conditions: If the machine is used in cold weather, pre-heat the engine with a spark plug. 
  • Engine malfunction: Read and refer to the engine manual instructions.


2.    Saw will not lower: 

  • Defective lower button: Check if you notice cracks, then replace lower button

  • Wrong blade: Ensure the blade matches the desired application, otherwise contact the blade manufacturer. 


3.    Saw will not raise:

  • Defective raise button: Check raise button, if it is worn out, replace it. 


4.    Engine starts too slow/too fast: 

  • False start: If your starter rope pulls without any resistance, you can remove the starter assembly. 
    • Note: Clean the starter assembly or replace the starter by adding lightweight oil, and place it back. 

5.    Gauging Compression: 

  • Lack of piston resistance: Piston rings can possibly be worn or the piston itself could be scoring. 
    • Note: Use a compression gauge to find the Pounds Per Square Inch (PSI). The ideal PSI for your saw is 160, anything less than 125 means a piston damage.


6.    Short belt life: 

  • Loose belts: Can cause slippage, check belt tension regularly. 
  • Sheaves are misaligned: Use straightedge to check proper alignment of the blade shaft sheave. 
  • Belts contacting pavement: Fix axle maximum depth in the front stop bolt for belt clearance. 
  • Mismatched belt: Replace the full belt set.
    • Note: Never mix old with new belt sets.
  • Power Take Off (PTO) is overheated: Check belt tension and lubricate PTO.
    • Note: We recommend lubricating PTO approximately every 20 hours after using the concrete saw.
