## Narrative

During the removal of the stick jack on a PC300 Komatsu excavator, an oring seal failed releasing hydraulic oil pressure which struck the mechanic in the left forearm. This resulted in bruising and swelling of the injured area. After X-rays and a medical examination it was determined no fluid had entered the skin.
