Hydraulic Power Source; Recommended Hydraulic Fluids - Greenlee 43179 Limb-Lopper Operation, Service And Parts Instruction Manual

GREENLEE FAIRMONT
Specifications — Hydraulic Power Source (cont'd)
* 200 psi is the maximum agreed standard for the Hydraulic Tool Manufacturers Association (HTMA). Greenlee
Fairmont tools will operate satisfactorily at this standard.
1. Maximum hydraulic fluid temperature must not exceed 140˚F (60˚C) at the maximum expected ambient tem-
perature. A sufficient oil cooling capacity is needed to limit the hydraulic fluid temperature.
2. Maximum hydraulic flow must not exceed 8 gpm @ 2000 psi. A pressure relief valve must be located in the
supply circuit between the pump and tool to limit excessive hydraulic pressure to the tool to 2000 psi.
Figure 3 shows a typical power source being used with the tool.
