• Optimal performance occurs at maximum flow.
• Maximum hydraulic fluid temperature must not
exceed 70
°
C (158
°
F). A sufficient oil cooling
capacity is needed to limit the hydraulic fluid
temperature.
• Hydraulic flow must not exceed 30 l/min (8 gpm).
Install a flow meter in the return line to measure the
rate of hydraulic flow before using the tool.
• Pressure relief valve setting must not exceed
160 bar (2300 psi) at your tool’s maximum flow.
Locate the pressure relief valve in the supply circuit
to limit excessive hydraulic pressure to the tool.
