Abstract [en]

Unintended oil leakage is a problem that occurs in a wide range of products in the forest and gardening sector. Presented as a basis for this thesis is an oil pump system designed to provide lubrication for the chain on a pole saw. In this system, unintended leakage occurs and creates a problem. The purpose and aim of the thesis are to investigate and determine the cause of the leakage and suggest how the problem can be solved.  Since the company which sells these pole saws profiles as environmentally conscious it is important to solve the issue.

To fulfill the purpose and aim of the thesis, several tests are set up to investigate the cause of the leakage. When an understanding is reached, the set-based concurrent engineering method is used to generate solutions and increase knowledge of the problem. These concepts were tested, and the outcome and effectiveness documented. 

The results are presented and discussed from the process of the thesis. The primary cause of the leakage is credited to an over-pressure building within the oil tank, forcing the oil through the obstructions and out the outlet. Included in the results and discussions are suggested solutions to the problem. Two concepts are included as solutions, as well as suggestions for future work and research of the problem.
