Enerpac BRD-Series - Manual (Page 3)

3. Make hydraulic connections. Use a pump
with a 4-way valve and two hydraulic lines.
Be sure all hydraulic lines are connected to
the correct inlet and outlet ports of the pump,
cylinder, valves, and other system
components.
All BRD and RD cylinders are equipped with
two 3/8"-18 NPT oil ports to allow for solid
pipe connections. When using flexible hose,
high-flow C-604 female couplers are
recommended.
Seal all pipe connections with a high grade
pipe thread sealer. If you use Teflon tape,
leave the first complete thread free of tape
to ensure that tape does not shed into the
hydraulic system, causing damage. Trim
loose ends.
IMPORTANT: Both oil ports must be
connected to a hydraulic line. These
cylinders do not have a safety valve to
prevent over pressurizing. If one of the oil
ports is plugged, the pressure may exceed
10,000 psi (700 bar).
4. Remove air from the system by extending
and retracting the cylinder 2 or 3 times.
4.0 OPERATION
Operate the hydraulic pump to advance and
retract the cylinder. Double-acting operation
develops both push and pull forces. However,
the capacity is higher when pushing and the
speed higher when pulling. See the Enerpac
catalog for specifications.
The cylinder stop ring is designed to take the
full load. However, to reduce cylinder wear, use
less than full stroke when possible.
5.0 MAINTENANCE
1. Use only Enerpac oil with these cylinders.
The use of any other oil may invalidate your
warranty.
2. Use dust caps when cylinders are
disconnected. Keep entire cylinder clean to
prolong cylinder life.
3. Store cylinders up-right to prevent seal
distortion.
6.0 TROUBLE SHOOTING
These cylinders should be repaired only by
Authorized Enerpac Technical Service Centers.
