## Narrative

EE was changing oil for 14G blade (unit 304002). As he reached in to change the filter, his arm was fully extended. When he pulled on the filter wrench, he felt a pull in his upper right arm, the muscle had been pulled. The poor design of this area of the blade is considered to be a major factor in this injury. It is very difficult to change oil filters on this equipment.
