RECEIPT OF GOODS
Unpack and visually check all the components, making sure that there are no oil leaks, loose or damaged
couplers, damaged threads, etc. Never use components that are damaged or appear to be in poor
condition.
SINGLE ACTING HYDRAULIC SYSTEM
The single acting hydraulic cylinders are fitted with one female quick coupler. If you have to fit the coupler
in the cylinder, apply teflon around the 3/8" NPT male thread of the coupler.
Assemble the device in accordance with the instructions given in the diagram, first checking that you have
all the necessary material.
-
Remove the dust protectors from the quick couplers and from the hose.
-
Clean quick couplers, hose ends and connectors.
-
Screw the male coupler to the hose. For that, apply teflon around the 3/8" NPT male thread of the hose.
-
Connect the other hose end to the pump. For that, apply teflon around the 3/8" NPT male thread of the
coupler.
-
Connect the hose end with the male coupler to the cylinder, tightening completely the couplers (first
insert as far as the plug will go and then screw it by hand). The couplers only must be connected or
disconnected when the hose is depressurised. For safety, as option, a manually operated check valve
AZ5200 can be mounted into the cylinder, that when is closed, allows oil flow in one direction only,
holding the load.
-
Ensure the connections are perfectly engaged to ensure the correct function of the system.
-
Bleed the cylinder. Locate the pump on a higher level than the cylinder, with the piston pointing
downwards and the coupler upwards. Extend and retract the cylinder several times, until it operates
properly.
SINGLE ACTING SYSTEM WITH 1 CYLINDER
Apply 2 rounds of teflon around all 3/8” NPT male threads of the system, in the thread
direction, leaving the first wire of the thread without covering to prevent the tape breaking.
Tightening Torque: 80 Nm.
Ensure that all the equipment and accessories are suitable for
the maximum working pressure.
