Plunger-to-body May lack unlocking pressure — Press HOLD TO OPERATE button and listen for valve
clamp faulty reliefs (“putt” sound).
1. If after three putts, cylinder will still not move, there may be insufficient hydraulic
pressure.
(a) Check intensifier hydraulic circuit for leaks.
(b) Check hydraulic pressure at the cylinder (Section 8.2).
2. If there are no putt sounds, check air pressure gage at secondary air pressure
regulator and make sure that solenoid valve is operative.
Clamp force not 1. Air may be in clamp system because of low oil level in the intensifier reservoir.
repeating (a) Bleed air at bleed port (Section 8.2).
(b) Fill intensifier reservoir (Section 4).
(c) Make sure all fittings and hoses leading from the reservoir to the clamp pump
are tight.
