2. Safety Information
Read all instructions carefully before assembly and use. Failure to follow these instructions may result in injury or product damage.
- Ensure all parts are securely fastened before use.
- Do not use the umbrella base in extreme weather conditions, such as strong winds or heavy storms, without additional securing measures.
- Verify that the umbrella pole diameter is compatible with the base (1.5 inches).
- Keep children and pets away from the assembly area.
- Always lower and secure your umbrella when not in use or during windy conditions to prevent tipping.
3. Setup and Assembly
The BESTEK Umbrella Base features a detachable snap-on design for straightforward assembly.
- Unpack Components: Carefully remove all parts from the packaging and lay them out on a clean, flat surface.
- Assemble the Base: Connect the four cross-shaped support legs to the central pole section. Ensure they snap securely into place. The design allows for easy attachment and detachment.
- Optional Ground Securement (for soft ground): If placing the base on soft ground (e.g., lawn), insert the four ground prongs through the designated holes at the ends of the support legs and into the ground for added stability.
- Optional Deck Securement (for hard surfaces): If placing the base on a wooden deck or concrete patio, use the four explosive screws to anchor the base. Note: This requires drilling pilot holes and appropriate tools (not included). Consult a professional if unsure.
4. Operating Instructions
Inserting the Umbrella
- Ensure your umbrella pole has a diameter of 1.5 inches for proper fit.
- Carefully insert the umbrella pole into the central tube of the base.
- Tighten the two pole thumb screws located on the central tube to secure the umbrella pole firmly in place. Ensure the umbrella is upright and stable before opening.

5. Maintenance
Regular maintenance will help prolong the life of your umbrella base.
- Cleaning: Wipe the base with a damp cloth and mild soap as needed. Avoid abrasive cleaners that could damage the powder coating.
- Inspection: Periodically check all screws and connections to ensure they remain tight.
- Storage: During off-season or prolonged periods of non-use, the detachable design allows for easy disassembly and compact storage. Store in a dry, protected area to prevent potential wear.
6. Troubleshooting
- Umbrella feels unstable:
- Ensure the umbrella pole is fully inserted into the base.
- Tighten both pole thumb screws firmly.
- Verify the umbrella pole diameter is 1.5 inches. An undersized pole may require shims (not included) for a snug fit.
- If on soft ground, utilize the ground prongs. For hard surfaces, consider using the explosive screws for permanent securement.
- Base appears to be rusting:
- The base is constructed from rust-free tempered iron with a powder coating. If rust appears, inspect for damage to the coating. Contact customer support if the issue persists.
