Release the lever and watch the pressure gauge(s):
• If the pressure drop is
less than 150 psi (10 bar) initially
and additional drop does not exceed 25 psi (1.7 bar) per
minute, the problem is not hydraulic. Refer to Section 3.3.
• If the pressure drop is more than 150 psi (10 bar) initially
and additional drop exceeds 25 psi (1.7 bar) per minute,
the CLAMP check valve cartridges in the revolving
connection may be faulty. Replace the cartridges.

Close the arms fully and hold the lever in the CLAMP
position for a few seconds. If the pressure still drops as
before, the cylinders are faulty and must be serviced. Refer
to Section 4.9.
