CAUTION
Driving a pin with a hammer can cause metal
pieces to fly off, leading to severe injuries. Wear
goggles, a hard hat, protective gloves, and other
personal protective equipment (PPE) during these
operations.
Make sure the surrounding area is clear of all
personnel when removing any of the pins. The
pins could fly out and cause personal injury.
Do not stand behind the bucket when removing
pins. Keep hands and feet clear of the underside
of the bucket during removal to avoid injury.
To avoid injury, do not use hands or fingers to aid
in bore alignment.

resistance on the pin could increase, causing
difficulty during removal.

arm pin (2) and link pin (3).
