1. Avoid dragging when installing the plastic fence to prevent reducing its lifespan. The water filling hole should face inward to prevent theft.

2. Increase water pipe pressure during filling to speed up installation, and fill until the water reaches the filling hole. Alternatively, fill one or more panels at a time based on the construction duration and site conditions. This method of filling will not affect the stability of the plastic barrier.

3. The product features a flag hole on top, suitable for inserting colorful flags or installing warning devices. It can also be used to drill holes in the plastic barrier panels for lighting fixtures or to secure and connect various items with self-tapping screws. Such minor installations will not affect the product's quality or performance.

4. In the event that a barrier is torn, damaged, or leaks during use, the repair process is straightforward. Simply heat it with a 300-watt and 500-watt soldering iron, and you can patch it up to your satisfaction.

5. The vibrant colors, due to the pigments produced by Germany's BASF Company, ensure no fading for five years when used outdoors.

6. During use, if the plastic barrier gets dirty with mud and dust, it can be washed clean by rain. For thicker mud, simply rinse with water. For sticky paint, asphalt, and other oil stains, use various cleaning agents to wipe and clean; this will not damage or impair the smoothness of the product's surface. However, avoid using sharp tools or scraping, as this can easily damage and destroy the smoothness of the plastic barrier's surface.

7. High-density polyethylene material has excellent recoverability. For products that are deformed and bent as a whole, they will quickly return to flatness as long as they are placed vertically and connected. Therefore, for inventory products, a flat cross-laid stacking method can be used to minimize the space required for inventory products.
