Setup: Choose a soft, level patch of ground, ideally grass or soil. Position the spike where you intend your airer to stand. Firmly push and twist the spike into the ground. For optimal stability, ensure the spike is inserted as deeply as possible and stands perfectly vertical. You may use a mallet if necessary, striking the flat top of the spike gently, ensuring not to damage the opening. Once the spike is firmly in place, insert your rotary airer pole into the opening. Compatibility: This ground spike is specifically designed to fit rotary airer poles and other outdoor equipment with a 3.2cm (32mm) diameter. It is compatible with Addis rotary airers and many other brands. Always measure your airer's pole diameter before purchase to ensure a correct fit. Care: The galvanised zinc construction is inherently low-maintenance. Periodically check for any accumulated dirt or debris around the opening and clean with a damp cloth if necessary. While designed for outdoor resilience, storing the spike indoors during extreme winter conditions or when not in use for extended periods can prolong its lifespan. Ensure no water collects inside the spike's opening if left exposed to rain.
