If the pressure never gets above 10,000 PSI, it indicates a weak Hydraulic Relief Valve #8 or a
leak in the system. Return to step twelve (12).
17. Repeat step fourteen (14).
18. Open By-Pass Valve #7 to relieve all pressure, and then retighten hand tight. Turn the Hydraulic Hand
Pump vertically with the Hydraulic Pump Hose Assembly #17 pointing up. Let stand for 5 minutes. Repeat
step thirteen (13).
If you cannot achieve a pressure of 5,000 PSI, it indicates there is air in the hydraulic system.
See
“Bleeding and Filling the Hydraulic Fluid Bag”
on page fourteen (14).
19. Open By-Pass Valve #7 to relieve all pressure. Remove the Test Fitting from the Giant Buttonhead
Coupler #17G.
This completes the test. If you made it through all nineteen (19) steps without incident, your Hydraulic Hand Pump
is in perfect working condition.
