32 Cleaning eneral During indoor use, the only cleaning required should be a regular wipe over with a lint-free cloth. Dirt accumulated during storage may be removed using a semi-stiff brush. Particular attention should be paid to the leg clamps and the tripod mounting face. Use out-of-doors under adverse conditions will require special attention. Salt spray should be washed off with fresh water at the earliest opportunity. Sand and dirt acts as an abrasive and should be removed using a semi-stiff brush or vacuum cleaner. NOTE: Use only detergent-based cleaners. DO NOT use solvent- or oil-based cleaners, abrasives or wire brushes to remove accumulations of dirt, as these damage the protective surfaces. Cleaning clamp sleeves 3 The leg clamps are fitted with removable clamp sleeves. In the event that sand, dirt or other contaminants have entered the clamp the sleeves may be removed for cleaning, as follows. NOTE: The illustration shows a top clamp. Other leg clamps are of similar construction. 3. Remove any payload from the tripod. 3.
