ASSEMBLY INSTRUCTIONS
1. Before assembly, identify all component parts included
with the set. Refer to the Flange Spreader Selection Chart
for identification of the component parts and to Figure 1 to
aid in the assembly procedure.
2. Hand tighten the hydraulic cylinder into the crossbar
making sure the cylinder collar threads are fully engaged.
(For cylinder RC-102, first remove thread protector.)
3. Thread the adaptor (F56-5 or F109-5) into the end of the
cylinder plunger until fully engaged, hand tighten only.
4. Thread the wedge provided (or the optional wedge, if
desired) into the adaptor until fully engaged, hand tighten
only.
5. Insert the small head of one of the side plates through
the slot in one end of the crossbar and rotate 90°. Repeat
this procedure for the other side plate into the slot at the
opposite end of the crossbar. The spreader is now ready to
be slipped onto the flange.
6. Connect the hose assembly to the proper port on your
pump. Use Teflon tape on the pipe threads and tighten with
a wrench.
IMPORTANT NOTE: Teflon tape is an excellent thread sealer.
However, if the tape is not properly applied, pieces may enter
the hydraulic system causing malfunctions and component
damage. Use 1-1/2 wraps of tape on each connection, leaving
the starting thread free of tape. Cut off all loose tape ends.
WARNING: If an Enerpac pump is not used, be
sure your pump does not exceed the rated capacity
of the flange spreader. Failure to do so could result
in personal injury or property damage.
OPERATING INSTRUCTIONS
IMPORTANT NOTE: Prepare the flange by loosening all the
bolts and removing one bolt for the insertion of the flange
spreader pin. Removal of the remaining bolts may be necessary
depending on your flange maintenance application. In some
cases, leaving one or two loosened bolts in the flange may be
helpful for realignment of the flange halves. Qualified personnel
should determine the proper method of preparation.
1. Slip the assembled spreader onto the flange. Align the
holes in the side plates with the flange bolt holes and insert
the pin through the side plates and bolt holes as shown in
Figure B. Insert the lockpins. Keep the side plates, pin and
crossbar centered on the flange.
2. Rotate the wedge clockwise allowing the tapered sides to
be forced between the flange faces. If the wedge cannot
be rotated sufficiently in a clockwise direction for proper
alignment, then rotate it counter-clockwise just enough to
align it with the flange. See Figure 2.
WARNING: Keep side plates close to flange face
while applying pressure Exceeding 1/4 inch
distance between side plate and flange face could
result in personal injury or property damage.
3. Connect the quick coupler on the hose to the quick coupler
on the cylinder and hand tighten.

4. Apply light pressure with the hand pump and check that
all connections fit securely. If so, proceed with the flange
spreading operation. If not, make needed adjustments
before proceeding.
NOTE: A light coating of grease on the wedge tapers will
make it easier for the wedge to be forced between the flange
faces.
CAUTION: Do not force the wedge between the flange
faces beyond the maximum width of the tapered sides of
the wedge or binding may occur.
5. If two flange spreaders are to be used to perform the task,
they should be positioned 180° apart.
6. To remove the wedge, open the release valve of the hand
pump. If the wedge binds, work the cylinder back and forth
to help walk the wedge out of the gap.
Refer to chart below for matching flange spreaders to pipe
sizes and ASA ratings.
