23. Maintain Labels and Nameplates. These carry important information and will assist you in ordering
spare and replacement parts. If unreadable or missing, contact an Elliott service facility for a
replacement.
24. Stop the Machine Immediately if the Flexshaft Starts to Coil. Flexshaft damage will occur if exshaft is
operated in a coiled position.
25. Use the Proper Flexshaft to t the tubes to be cleaned. Never use a exshaft that is too small or too
short. Flexshaft failure will result if too great a resistance is placed on the exshaft. Refer to the chart
below for sizing information. (See Fig. 1 and 2)

OPERATION
Correct Machine Position and Operation is critical to getting the job done quickly and efciently.
This can be accomplished by the following these steps:
Examine the tubes to be cleaned and measure the internal diameter (Elliott Tube Gage is
recommended) and length of the tubes. If the tube ends are expanded, then make a note of the
smallest internal diameter. Record these measurements on the charts provided on page 22 and 23
of this manual. You will need these measurements to select the proper size exshaft and cleaning
attachments.
Roll or hand carry the machine to the location where the cleaning will take place.
Position the machine at a right angle to the tube sheet or cleaning area. This will keep the exshaft
at the proper radius. NEVER OPERATE THE MACHINE IN THE VERTICAL POSITION. (See Diagram
A page 7).
Remove pin from handle bracket and lower handle on the machine to its lowest setting and replace
the handle pin.
Lower the machine to the horizontal position, resting the end of the handle on the oor.
Open the foot switch storage compartment and remove the foot switch, “O” ring, and rubber hose
washer.
Position lug on foot pedal plug to line-up with slot in plug receptacle and push plug in place. Then
thread the outer ring of the foot pedal plug onto the plug receptacle until tight. The foot switch can
only be connected in one position.
Place the rubber hose washer in the water hose connection of the machine. This is a one time
operation. The rubber washer can remain in this connection and does not require removal after use.
Connect a standard garden hose to the 3/4” water hose connection of the machine. The machine
is designed for “Municipal” water pressure only, Max 100 psi (6.89 Bar-Metric). DO NOT connect
the water connection to a “High Pressure” source. Water is important to the cleaning process as it
ushes away deposits cleaned from the tube and helps to lubricate and cool the exshaft.
Position the “O” ring in the recess of the exshaft connection manifold.
TOOL TIP
Always select a smaller size of cleaning device for heavy
tube deposits. With the exception of the Elliott Turbo Brush,
never use a brush or cleaning device larger than the internal
diameter of the tubes.

OPERATION (CONT.)
Prepare the exshaft by loosening the four (4) set screws located in the brass locking sleeve using
a 3/32” Allen wrench. Thread the breakaway or solid square drive into the coupling adapter that
is swaged on the core of the exshaft. Position the brass locking sleeve equally over the coupling
adapter and the breakaway or solid square drive. Firmly tighten the four (4) Allen set screws. (See
Diagram B page 9)
Insert the square drive into the manifold of the machine. Rotate the exshaft by hand to properly seat
the square drive of the exshaft into the manifold. Thread the brass manifold cap onto the manifold of
the machine and rmly hand tighten.
Attach the chosen cleaning device to the tool coupling swaged to the core of the exshaft at the
opposite end from the manifold connection and rmly tighten the device.
Plug the machine into the appropriate electrical source. For more information see “Electrical” section.
Turn on the water supply.
Layout the exshaft as straight as possible. DO NOT start the machine with the exshaft in a coiled
position.
Depress the foot switch. The electric motor will operate and drive the exshaft, which will rotate
the cleaning device. At the same time, water will pass through the machine and out the end of the
exshaft casing near the cleaning device. Remove your foot from the foot switch and both the water
and rotation of the shaft will stop. Restart the machine and observe the water output from the end of
the exshaft casing. A constant stream of water should be discharged from the casing as the core
rotates. If no water is discharged from the exshaft, check the hose and hose connection for any
“kinks” that would restrict water ow. If there is no rotation of the exshaft, check the Ground Fault
Circuit Interrupter (GFCI) reset button. For more information see “Electrical” section. Depress the foot
switch again and observe the water ow from the end of the exshaft. If no water is discharged, from
the exshafting, discontinue use of the machine and contact an Elliott service facility.
For model 0620AR, let machine completely stop rotation before depressing the reversing peddle.
Reverse rotation and water ow will begin when the reverse peddle is depressed and will stop when
released.
TOOL TIP
For model 0620AR machines, to prevent the cleaning device from unthreading
when using the reverse mode of the machine, place a 1/4” lock washer
between the tool coupling and the cleaning device and rmly tighten the
connection.
