1. The trowel machine emits black smoke during operation.

Check the trowel machine to ensure it’s not over-oiled—if there’s excess oil, drain some off. Alternatively, severely worn or damaged pistons can also cause oil burning; in such cases, replace them promptly if necessary. Next, inspect the engine. If the engine is functioning properly, the issue might still stem from excessive oil contamination. Remember, oil quality is crucial—always opt for high-quality机油, and when purchasing, be extra cautious to avoid counterfeit or low-grade机油.

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 the screws so their heights match. 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, which will automatically shut off the engine when the oil level drops too low. Additionally, after disconnecting the remote engine-shutdown switch one by one from the machine's main shutdown switch, if 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 it again to see if everything is working 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.
