    If particles of dirt or wax are present, the operator can face difficulties trying to achieve satisfactory pressure balance in the mechanical retrieval tool. The pressure difference can force the mechanical tool to expand uncontrollably, potentially causing harm to the operators. Apply pressure above pipeline pressure to the tool by an external pump. www.Emerson.com/Roxar...
