Setup and Assembly
Your Grand Patio Cantilever Umbrella arrives in two packages, complete with all necessary tools, hardware, and a detailed instruction manual. Assembly typically takes approximately 30 minutes. It is recommended to assemble the umbrella in its final desired location before filling the base, as it becomes very heavy once filled.
Base Preparation
The umbrella's base is designed for stability and must be filled. For optimal stability, fill the base with 330 lbs of sand and 44 lbs of water, totaling 374 lbs. The base includes wheels for easier movement before filling.

- Attach the main pole to the base, ensuring all connections are secure.
- Assemble the umbrella canopy frame and attach it to the main pole.
- Once assembled, carefully fill the base with the recommended sand and water mixture.

Operating Instructions
The Grand Patio Cantilever Umbrella is designed for ease of use, allowing you to quickly open, close, and adjust the shade as needed.

Tilt Adjustment
The umbrella features a clever auto-lock system that allows you to reposition the tilt of the umbrella up to 90 degrees, providing maximum shade throughout the day as the sun moves.
- To adjust the tilt, locate the position lock mechanism on the pole. Engage the lock to secure the umbrella at your desired angle.
- Ensure the umbrella is securely locked in position after adjustment to prevent unwanted movement.

Safety Precautions
- For safety in bad weather conditions (strong winds, heavy rain), always close the umbrella and secure it in the deadlock position when not in use.
- Do not attempt to move the umbrella once the base is filled, unless absolutely necessary and with adequate assistance, as it is very heavy.
