Package Contents
Please verify that all components are present before beginning assembly:

Setup and Assembly
Assembly of the US Weight Umbrella Base is straightforward and requires minimal effort.
- Position the Base: Place the umbrella base on a flat, stable surface where your patio table will be located. Ensure the base is centered under the umbrella hole of your patio table.
- Prepare the Stem: The base features a 10.5-inch stem with adjustable collars. These collars are designed to accommodate umbrella pole sizes ranging from 1.3 inches to 1.8 inches in diameter. If your umbrella pole is at the larger end of this range, you may need to remove the inner collar for a proper fit.
- Insert Umbrella Pole: Carefully insert your patio umbrella pole through the umbrella hole in your patio table and down into the stem of the umbrella base.
- Secure the Pole: Locate the support knob on the side of the stem. Rotate this knob clockwise to tighten it against the umbrella pole. Continue tightening until the pole is firmly secured and does not wobble.

Operating Instructions
Using your US Weight Umbrella Base is simple once assembled:
- Daily Use: Ensure the umbrella pole is always securely tightened within the base's stem before opening your umbrella.
- Adjusting Pole Fit: If your umbrella pole feels loose, re-tighten the support knob. If it's too tight or doesn't fit, check the adjustable collars inside the stem. The inner collar can be removed to accommodate wider poles (up to 1.8 inches).
- Relocation: If you need to move the base, always lift it carefully from the bottom. Avoid dragging the base, especially on rough surfaces, to prevent damage to the base or its PVC feet.

Maintenance
Proper care will extend the life of your umbrella base:
- Cleaning: Clean the cast stone base with a soft cloth and mild soap and water. Avoid harsh chemicals or abrasive cleaners, which can damage the finish. Rinse thoroughly and allow to air dry.
- Winter Storage: To protect the cast stone material from freezing and thawing cycles, it is highly recommended to store the umbrella base indoors during winter months or periods of prolonged freezing temperatures.
- PVC Feet: Periodically inspect the four PVC feet on the bottom of the base for wear or damage. These feet provide a non-slip grip and protect surfaces.
