● When hitting the pin with a hammer, metal shavings may fly into the eyes and cause serious injury. When performing
this operation, always wear goggles, helmets, gloves, and other protective equipment.
● When unloading the bucket, place the bucket steadily.
● If you hit the pin hard, the pin may fly out and injure people in the surrounding area. Therefore, before hitting the pin,
make sure that the surrounding area is safe.
● When disassembling the pin, pay special attention not to stand under the bucket, and do not put your feet or any part of
your body under the bucket.
● When removing or installing the pin, be careful not to hurt your hands.
● When aligning the hole, do not put your fingers in the pin.
