CAUTION!
• Keep fingers and other body parts away from pinch points to prevent crushing injuries
while removing or installing the bucket. Never put your finger into the pin bore during
alignment.
• Secure buckets after removal and before servicing.
• Bucket pins may be ejected with extreme force when removed forcefully. Do not allow
anyone to stand in front of the pins during removal.
