2. Make sure the hydraulic tool about to be operated is at a
safe setting.
3. Plug tool into quick-disconnect fittings mounted on plat-
form rail. The male quick connect is the pressure feed
line.
4. Set flow control knob to desired setting.
NOTE: Each notch in the flow control knob corresponds to
approximately 1 GPM (ex. setting 2 = 2 GPM). At setting
seven (7) the pump has reached its maximum flow rate
therefore any setting past 7 will produce no additional
flow.
