Testing the pressure limit of the hand pump
To protect the mechanical components from overload, not more than
300 bar (4350 psi) of pressure may be built up. This is what the pressure
limiting valve integrated in the hand pump is for.
› Make sure that the pressure relief valve (see fig. 4 on page 19) is
closed. To do so, rotate the handwheel clockwise as far as it will go
and tighten it by hand.
› Pump using the lever until the manometer shows 300 bar (4350 psi).
› Keep pumping with the lever.
The displayed pressure must not rise beyond 300 bar (4350 psi).
› If the displayed pressure rises beyond 300 bar (4350 psi), contact the
LPKF Support.
› Rotate the handwheel counterclockwise, to lower the hydraulic
pressure and finish the test.
