INTRODUCTION
Thank you for purchasing this Elliott product. The design and manufacture of this
machine, represents the highest standard of quality, value and durability. Elliott tools
have proven themselves in thousands of hours of trouble free field operation.
If this is your first Elliott purchase, welcome to our company; our products are our
ambassadors. If this is a repeat purchase, you can rest assured that the same value you
have received in the past will continue with all of your purchases, now and in the future.
The Elliott Baffle Expander is a lightweight, portable tube expansion system designed to
expand tubes at the support plates or baffles in heat exchangers, chillers, and
condensers. The adjustable hydraulic pressure allows for consistent expansion,
eliminating the risk of over expansion that can lead to tube failure. This tool is not
designed for heavy expansion at the primary tube sheets.
We at Elliott would like you to be completely satisfied with this machine and therefore
recommend that this instruction manual be thoroughly read prior to use.
This machine has been designed and manufactured to the highest standards, using the
latest in materials and technology. If the guidelines and maintenance schedules in this
manual are followed, the Elliott Baffle Expander will provide many years of trouble free
operation.
Elliott Tool Technologies Ltd shall not be liable for errors contained herein or for incidental or consequential damage in connection
with the furnishing, performance, or use of this material.
Figure A
OPERATION
1. Measure the distance from the face of the tube sheet to the center of the baffle
support plate being expanded.
2. Assemble the collet extensions (7) and draw bar extensions (5) as required to reach
the needed length.
3. Position the location collar (6) so that the collet (3) will be properly positioned under
the support plate. See diagram above.
4. The pump pressure controls the amount of tube expansion achieved. To set this
pressure properly, a sample piece of tube (similar to the tube in the heat transfer
vessel) will be required. Set the hydraulic pump to 400 PSI. Depress the pendant
switch to the on position for 2 to 3 seconds. This will retract the draw bar (4) and
expand the collet (3) and the tube sample. When the pendant switch is released, the
collet expander will be returned to its minimum diameter.
5. To adjust the minimum and maximum expansion of this tool loosen the split collar (8)
set screw and adjust the threaded adapter (5) either inward to increase the diameter,
or outward to decrease the diameter. The entry diameter should be .005” to .015”
under the minimum ID of the tube. Increase the pump pressure in 50 PSI increments
until the proper expansion rate has been achieved. Note: DO NOT exceed 1,500 PSI
as over-expansion and tube damage could occur. Once the proper expansion rate
has been achieved, you are ready to begin expanding the tubes in the heat transfer
vessel.
6. Insert the collet expander into the tube until the location collar (6) is seated against
the tube sheet. Depress the pendant switch for 2 to 3 seconds to expand the tube as
in step 4 above. Release the switch to return the collet expander to its minimum
diameter. Note: When using 2 or more extensions, center support of tool is required.
7. At this time you can rotate the expander 30° and repeat step 6 to maximize the tube
to tube support contact, or you can move to the next tube.

SAFETY
Every effort has been made to ensure the operation of the Elliott Baffle Expander is safe,
although it is impossible to remove all possibilities of accidents.
It is very important that all operators of this machine are fully aware of the following safety
considerations.
1. If you are unfamiliar with the Elliott Baffle Expander, read this Operation Manual thoroughly
before use.
2. Always wear safety glasses, protective gloves, safety shoes and protective clothing.
3. Do not allow other people in the area of the machine unless they are wearing suitable
protective clothing and equipment. Do not allow other people at the opposite end of the tube
while expanding. In the rare event of draw bar failure, the draw bar can be expelled from
the tube with dangerous force.
4. As the machine is hydraulically driven, hydraulic oil leaks from the ram and hose
connections are possible. If hydraulic oil is leaked, clean-up oil immediately to avoid
slippery floor surfaces.
5. The Elliott Baffle Expander stroke is controlled by a manual control on the hydraulic power
source. It is important to read and understand the manual for the hydraulic power source.
6. Ensure all hydraulic connections are properly made and that the hoses are in good
condition.
7. Always be aware of the location of hydraulic power shut off valve.
8. Always shut down the hydraulic power supply before changing tooling.
9. Do not operate the machine if there appears to be damage to the machine, if parts are
missing, or if performance appears to be unsatisfactory.
10.Never use the Baffle Expander, or any other power tool when under the influence of
medication, drugs or alcohol that decrease concentration and impair operator control.

START-UP
Unpacking
The Elliott Baffle Expander Kit is shipped, complete with baffle expander, hydraulic
ram, hose and pump. On arrival, check for external damage to the cartons. If damage
is found, notify the carrier and the supplier so insurance inspectors can examine the
box before it is unpacked. When opened, check the contents against the packing and
parts list. Report any damage or shortage to Elliott.
Ensure that there is no packaging material left inside the openings of the hydraulic ram
or any other hydraulic port.
Connecting to Hydraulic Power Supply
The Elliott Baffle Expander includes a hydraulic power source. The hydraulic power
source supplied by Elliott will be either Elliott Model M5767-00 (115 Volts) or M5767-
220 (230 Volts). An optional pneumatic pump is available.
1. Position the Elliott Baffle Expander and the hydraulic power source on a flat
surface.
2. Connect the 15’ hydraulic hose to the ram and pump.
3. Follow the directions of the Elliott hydraulic pump manual to assure that the
hydraulic pump is working properly.
4. Cycle the Baffle Expander Ram several strokes to eliminate any air in the
hydraulic lines.
5. The Elliott Baffle Expander Ram is ready for installation of the baffle expander.
Connecting to Baffle Expander (Refer to page 5 – Tool Selection Guide)
1. Thread the threaded bushing (8) into the hydraulic ram. Make sure that the
screwdriver slot is facing outward. Use a screw driver to final thread the bushing
firmly into the hydraulic ram. Set the hydraulic ram aside until step 6.
2. Select and connect the number of 4’ draw bar (5) and collet extensions (7) that will
be required for your task. It is best to insert the draw bar extension into the collet
extensions before assembling extensions together.
3. Thread the collet (3) onto the end of the collet extensions (7).
4. Pull out the end of draw bar extension(s) (5) assembly from the collet extension(s)
to expose the flat. Use a wrench to hold the draw bar extension while threading on
the draw bar (4). Use a second wrench on the draw bar flat to firmly tighten the
draw bar to the draw bar extension assembly.
5. On the opposite end of the collet extension assembly, thread on the collet
extension adapter (2). The complete assembly is now ready to be connected to
the hydraulic ram.
6. Connect the complete assembly to the hydraulic ram by threading the collet
extension adapter end of the assembly into the hydraulic ram. Tighten firmly.
7. Internally thread the draw bar extension into the threaded bushing in the hydraulic
ram. Tighten firmly.
8. The Baffle Expander is now ready to use.
