Page 5: Safety And Personnel
The person(s) working with the regulator should be capable of working with basic hand tools and identifying mechanical components of a hydraulic system. Contact Oilgear for any further training or documentation regarding any issues related to Oilgear supplied equipment.
Page 6: Operational Descriptions
2.1.5 Component Life Expectancy Based on the listed operational requirements, Oilgear recommends a seal replacement period of every 5 years. Internal valve parts should be inspected or replaced as needed. Depending on use and operating conditions, preventative maintenance of valve kit components should be considered. Main external components should be evaluated by the user and not subject to any specific maintenance schedule.

Page 31: Troubleshooting
1. Always vent all pressure from the system prior to removing components. 2. Standby vent leakage is often a sign of an internal problem. For this reason, Oilgear recommends venting the regulator directly to atmosphere through use of a short tube or open port. This allows problems to be more easily traced to a single component.
