ABSTRACT A device for automatically replenishing and exchanging hydraulic fluid in the hydraulic system (such as that of a fastener placing tool 31) comprises a lower reservoir (29) for holding new hydraulic fluid (39) and an upper reservoir (28) for reciving old hydraulic fluid. The device connects with the system to be replenished by means of a single hydraulic fluid connection (17) at the bottom of the lower reservoir (29). An entry port (25) to the second reservoir is positioned opposite the connection (17) at the bottom end of a tube (23) leading to the top of the second reservoir. In use, the device is connected to the hydraulic system through the connection (17) and the system is pressurised. Old hydraulic fluid is forced up through the connection (17) at high speed and passes through the new hydraulic fluid (39) in the lower reservoir (29), through the port (25), up the tube (23) and down into the upper reservoir (28) where it is retained. When the system is depressurised, new hydraulic fluid (39) is drawn down through the same connection (17) into the hydraulic system.
