Hydraulic Power Source (cont'd)
1. Maximum hydraulic fluid temperature must not
exceed 60 °C (140 °F). A sufficient oil cooling
capacity is needed to limit the hydraulic fluid
temperature.
2. Hydraulic flow must not exceed 46 l/min (12 gpm).
Install a flow meter in the return line to measure the
rate of hydraulic flow before using the tool.
3. Pressure relief valve setting must not exceed
138 bar (2000 psi) at your tool's maximum flow.
Locate the pressure relief valve in the supply circuit
to limit excessive hydraulic pressure to the tool.
