1. The trowel machine emits black smoke during operation.

Check the trowel machine to ensure it’s not over-oiled—if there’s too much oil, drain some off. Alternatively, severely worn or damaged pistons can also cause oil burning, so replace them promptly if they’re faulty. Next, inspect the engine: if no mechanical issues are found, the problem might be excessive oil contamination. Remember, oil quality is crucial—always opt for high-quality机油 and take care to avoid purchasing low-grade or counterfeit机油 when making your purchase.

2. How to adjust the leveling screws on the screed machine chassis

First, replace the four new blades and place the trowel machine on a perfectly level surface. Next, remove the fork and visually check whether the four screws are at the same height. If possible, use a ruler to measure—adjust any screws that aren’t evenly aligned until they’re all at the same height. Finally, gently wiggle the pressure cap; if there’s no movement, it means the adjustment was successful. To prevent wear and tear, apply a small amount of grease to the top of each screw.

3. The screed machine keeps stalling.

Check whether the oil level is normal and if the机油 (engine oil) is too low. Some machines come equipped with their own机油 protection systems—when the oil level drops too low, the engine will automatically shut down. Additionally, if you disconnect the remote engine shutdown switch one by one from the machine’s main shutdown switch, and the engine no longer stalls after each disconnection, it indicates that there’s a ground fault in that particular circuit. Simply perform a thorough inspection to identify and eliminate the issue.

4. The screed machine's engine is running normally, but it can't drive the screed plate effectively.

If the engine is fine, it’s likely due to the wrong belt model or a belt that’s too long. If the issue persists, simply replacing the clutch should usually do the trick.

5. The gasoline trowel was soaked in water.

First, clean the carburetor, then remove the spark plugs to check if water has entered the cylinder head. If water is present, crank the engine several times to expel the water completely. After changing the机油, try starting the engine again to see if everything is functioning properly.

6. The trowel machine won’t turn.

Reasons: The blade may be deformed; the motor bearing is damaged; the motor bracket is not securely fixed; or there’s an issue with usage.
