Creaking sounds are normal for pergolas, as materials can expand or contract with temperature changes.
However, you can take the following steps to reduce or eliminate the noise:
Check the Connecting Assembly
Ensure the motor arm is securely fastened to the beam.
Tighten the Bolt
Locate the bolt (circled in red in the manual diagram) and tighten it to prevent unnecessary movement.
Lubricate Moving Parts
Apply lubricant to moving parts, especially where the louvers connect to the guide rail.
Use Silicone Sealant
Apply silicone sealant at the joints to minimize noise caused by material movement.
Tip: Regular maintenance can help prevent creaking and extend the lifespan of your pergola. Refer to "Cleaning the Pergola"
