Operating the M2 Unit
Starting the Hydraulic Motor & Pump
Starting the hydraulic driven pump
Make sure the hydraulic variable speed control lever (Fig.13) is in the stop position (all the way over to
the left stop pin).
Start YOUR hydraulic power unit as per the manufactures instructions and let the hydraulic oil reach
the recommended operating temperature.
Make sure the centrifugal trash pump is primed and all valves are open / closed as the previous
instructions indicated.
Do a visual check for hydraulic fluid leaks.
The hydraulic variable speed controller may now be SLOWLY rotated to the right, approximately 1/4 to
start the trash pump, pumping fluid through the system. This will allow the hydraulic oil to fill the lines
and come up to speed. At this point you should see fluid entering your reservoir tank via the fluid return
hose.
Remember that the system is pumping fluid under pressure, even when the valve is at a low setting.
Gradually rotate the control lever (right) toward the high-speed position and set at the required speed
(GPM).
DO NOT EXCEED 10.3 GPM (Use flow meter to determine GPM)
Note: Whenever high-speed operation is not required, rotate the speed control lever (left) to approximately
1/2 speed, to extend hydraulic motor and pump life.
The Gorman-Rupp
®
used on this unit is self-priming. Priming is not required as long as the pump is kept
full of liquid.
