ASSEMBLY AND REPLACING ELEMENT INSTRUCTIONS
01/03.2011
MOUNTING
Once you have checked the integrity of the filter inside its
package, proceed as follow:
A Take off the protection cap from the in/out ports.
B Secure the filter in the head through the holes of the upper
side (pos.2) tightening them as follows:
HF 620-20/30 and HF 625-20/30 = 44 lbf in (5 Nm)
HF 620-40 and HF 620-50 = 62 lbf in (7 Nm)
C Connect circuit's pipes to inlet and outlet ports using the
tightening torque indicated on pages 22 and 23.
D If the filter has a clogging indicator (pos.3 - 4 - 5 - 6 - 7 - 8), take
the protection cap off and screw the indicator in the dedicated
seat, then tighten to a tightening torque of 266 lbf in (30 Nm). If
the indicator is electric, complete the required connections.
E Start the circuit for a few minutes.
F Make sure there are no leaks.
REPLACING ELEMENT
Once the working hour limit indicated in the manteinance
instructions of the system is reached or when the clogging
indicators point out the limit pressure drop created inside the
filter, the element must be replaced. Pay attention to the
drainage of hydraulic oil, therefore prepare suitable containers to
collect it.
Proceed as follows:
A Stop the system in "machine stopped" status.
B Secure any shut-off valves on the hydraulic circuit.
C Remove the clogged element by hands-crewing it from the
