4. Transportation and Storage
* This state-of-the-art indoor machine requires diligent care during transportation and storage to avoid damage from rain, snow, or other harsh elements. Pay extra attention to the warning labels during loading and unloading processes. Ensure the storage warehouse is dry, with excellent air circulation, and free from corrosive gases or dust. The optimal temperature range is -25ºC to 55ºC with relative humidity below 90%.
* If extended storage is necessary post-unpacking, repack the product following the original packaging requirements. Prior to storage, always clean the machine and seal it meticulously with plastic bags.
* Users should maintain the integrity of the cartons and shock blocks for effective packaging, especially for long-distance transportation. For such cases, reinforce the packaging with a sturdy wooden case and clearly mark it with 'up' or 'rain' symbols to ensure safe handling.
