34 HANDHELD TOOLS 800-972-2647 www.stanleyinfrastructure.com HOSE TYPES The rated working pressure of the hydraulic hose must be equal to or higher than the relief valve setting on the hydraulic system. There are three types of hydraulic hose that meet this requirement and are authorized for use with STANLEY Hydraulic Tools. They are: • Certified non-conductive - constructed of thermoplastic or synthetic rubber inner tube, synthetic fiber braid reinforcement, and weather resistant thermoplastic or synthetic rubber cover. Hose labeled certified non-conductive is the only hose authorized for use near electrical conductors. • Wire-braided (conductive) - constructed of synthetic rubber inner tube, single or double wire braid reinforcement, and weather resistant synthetic rubber cover. This hose is conductive and must never be used near electrical conductors. • Fabric-braided (not certified or labeled non-conductive) - constructed of thermoplastic or synthetic rubber inner tube, synthetic fiber braid reinforcement, and weather resistant thermoplastic or synthetic rubber cover. This hose is not certified non-conductive and must never be used near electrical conductors. RECOMMENDED HOSE CONFIGURATIONS When a longer hose configuration is used by connecting hoses together, system back pressure is increased. Too high a back pressure may reduce performance and life of the tool. STANLEY recommends back pressure not to exceed 250 psi / 17 bar. In addition, oil temperature should be limited to 140 degrees F / 60 degrees C. For both 5 and 8 gpm (20 - 30 lpm) tools, standard hose with a 1/2” inside diameter is acceptable to use up to 100’ or 30 m when configured with (2) sets of 50 feet hose. STANLEY does not recommend the following configurations with 1/2” diameter hose. • (4) sets of 25’ hose • (1) set of 50’ hose + (2) sets of 25’ hose These configuration will drive back pressure beyond recommended levels. For longer lengths between 100’ to 300’ STANLEY recommends increasing the hose diameters to the following: Pressure Line - 5/8” Inside Diameter Hose Return Line - 3/4” Inside Diameter Hose The increased hose diameter will alleviate back pressure and allow proper tool operation. PERFORMANCE NOTES When operating with longer hose lengths with the same diameter hose, back pressure increases. When operating hydraulic tools at 100’ with the 1/2” diameter hose, some decrease in performance is possible. This should not noticeably affect overall performance of the tool, but note it is not under optimal conditions with longer hose configurations.
