Hydraulic Power Source
Do not exceed the following hydraulic power source
maximums:
• Hydraulic flow: 30.3 l/min (8 gpm)
• Pressure relief: 138 bar (2000 psi)
• Back pressure: 13.8 bar (200 psi)
Failure to observe this warning could result in severe
injury or death.
Type of Hydraulic System ........................Open-Center or
Closed-Center
Flow
Minimum ......................................... 15.1 l/min (4 gpm)
Recommended ................................ 22.7 l/min (6 gpm)
Maximum ........................................ 30.3 l/min (8 gpm)
Filtration .............................................10 Micron (nominal)
Pressure Relief Setting ........................ 138 bar (2000 psi)
Back Pressure (Maximum*) .................. 13.8 bar (200 psi)
* 13.8 bar (200 psi) is the maximum agreed stan-
dard back pressure for the HTMA (Hydraulic Tool
Manufacturers Association). Greenlee Utility tool will
operate satisfactorily at this standard.
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 30.3 l/min (8 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.
