OPERATION & MAINTENANCE MANUAL STE35SR
Bucket Replacement and Inversion
When pins are knocked in with a hammer, pieces of metal may fly and cause serious injury.
When carrying out this operation, always wear goggles, hard hat, gloves, and other protective
equipment.
When the bucket is removed, place it in a stable condition.
If pins are hit with a strong force, there is a hazard that the pin may fly out and injure people in
the surrounding area. Make sure that there is no one in the surrounding area before starting
the operation.
When removing the pins, do not stand behind the bucket. In addition, be extremely careful not
to put your foot under the bucket while standing at the side for the work.
When removing or inserting pins, be extremely careful not to get your fingers caught.
Never insert your fingers into the pin holes when aligning the holes.
IMPORTANT
After removing the pins, make sure that mud or sand does not get on them. Dust seals are fitted at
both ends of the bushings, be careful not to damage them.
