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.
