    Maintenance Maintenance Dismantle the separator and the exhaust filter, if present, before servicing. Check the overpressure valve (accessory) at the oil reservoir during maintenance, if an overpressure valve is installed. Checking the overpressure valve ist described in the instructions for use of the overpressure valve. In the event of oil leakage from the pump (oil dripping from the bottom of the housing), it is often sufficient to replace only the replacement sleeve or the oil reservoir seal.
