5. Operating Instructions
5.1 Filling the Base for Stability
For optimal stability, the base must be filled. You can use either water or sand:
- Water: The base can hold approximately 72 liters (158 lbs) of water.
- Sand: The base can hold approximately 242 lbs of sand. Sand provides greater stability than water.
Ensure the fill cap is securely closed after filling.
5.2 Adjusting the Height
The DUMOS basketball hoop features an adjustable height mechanism, allowing the rim to be set between 6.1 feet and 10 feet. This is achieved by adjusting the pole sections.

To adjust the height:
- Loosen the locking mechanism on the pole.
- Carefully raise or lower the upper pole section to the desired height.
- Ensure the pole is securely locked into place at the chosen height before use.
5.3 Portability
The integrated wheels on the base allow for easy movement of the basketball hoop. To move the hoop:

- Ensure the base is filled for stability during movement.
- Tilt the hoop slightly forward to engage the wheels.
- Roll the hoop to the desired location.
- Once in position, gently lower the hoop until the entire base rests flat on the ground.
6. Maintenance
- Regular Cleaning: Clean the backboard and rim regularly with a mild soap and water solution. Avoid abrasive cleaners.
- Check Fasteners: Periodically check all bolts, screws, and connections to ensure they are tight. Tighten as necessary.
- Base Level: Ensure the base remains adequately filled and level to maintain stability.
- Weather Protection: While designed for outdoor use, prolonged exposure to extreme weather conditions can affect the product's lifespan. Consider covering the hoop or storing it indoors during harsh weather.
- Rim and Net: Inspect the rim for any deformation and the net for tears or excessive wear. Replace the net if damaged.
7. Troubleshooting
- Hoop is Unstable:
- Ensure the base is fully filled with water or sand. Sand provides superior stability.
- Check that all pole connections and base fasteners are securely tightened. - Difficulty Adjusting Height:
- Ensure the locking mechanism is fully disengaged before attempting to adjust the height.
- Check for any obstructions or debris in the pole sections. - Backboard or Rim is Loose:
- Tighten all bolts connecting the backboard and rim to the pole.
