INSTALLATION TIPS
Excessive pressure in your return line will damage the hydraulic motor seal. High back pressure can be caused by
“spikes” sent back through the return from other equipment on a common return line. Another potential problem
can develop if several pieces of equipment are connected to one “common” return line causing a high back
pressure (150 PSI is the maximum). We recommend you run the return line from the generator back to the
cooling tank with a separate line.
You can either run the 3/4 inch return line back to the tank or leave the 3/4 inch line connected to a common
return and run a separate 3/8 inch line from the case drain (located at the bottom of the hydraulic motor) directly
back to the tank. Either way you completely eliminate any problem of excessive return line pressure damaging
your hydraulic motor.
