Using this Amtech 140cm red fence post hole digger is easy. First, decide where you want to dig the hole. Hold the digger firmly by the handle and drive it into the ground with a downward motion. Then, lift it up to remove the soil. Keep repeating this process until you reach the desired depth. When using it, make sure to wear appropriate safety gear like gloves and safety glasses. Also, avoid using it on extremely hard or rocky ground as it may damage the digger. For maintenance, after each use, clean the digger to remove any dirt or debris. Store it in a dry place to prevent the zinc - plated fiberglass shaft from corroding. If the handle shows signs of wear, check it regularly and replace it if necessary.
