1. Using your Elliott catalog or the Elliott Product Selection CD, select the appropriate
flexible shaft and cleaning attachments for the tube size and conditions. Thread the
cleaning device into the tool coupling of the flexible shaft.
TOOL TIP: When using a reversing direction drive Roto-Jet II®, install a ¼” lock washer
between the tool coupling and the cleaning device. Firmly tighten the connection.
2. DO NOT operate a coiled flexible shaft. Set the Roto-Jet II® at a right angle to the tube
sheet of the vessel being cleaned. (See Diagram 2) Position the flexible shaft in a large
loop allowing the shaft to enter and exit the tube in a safe radius.
3. Measure the length of the tubes being cleaned. Transfer that measurement to the flexible
shaft, from the end of the cleaning device up the flexible shaft casing toward the machine.
Mark the casing at that point using electrical tape or a hose clamp snugly tightened on
the casing. This is to prevent the cleaning tool from exiting the tube.
NOTE: Allowing the cleaning device to exit the tube while the shaft is spinning will cause
the shaft core to fracture, breaking the shaft at that end.
4. Insert the cleaning device into the tube end, start the cable rotation by depressing the
footswitch. On the 0650R reversing unit, the “LEFT” footswitch is forward or clockwise
direction drive and the “RIGHT” footswitch is reverse or counterclockwise drive.
a.) Your Roto-Jet II® is equipped with a solid state speed control. This will allow you
to adjust the shaft rotation speed from 0 to nearly 1800 RPM.
b.) We recommend starting at 25% to 50% of the maximum speed for an initial pass
down the tube. Evaluate the level of resistance met and adjust the shaft speed to
allow the safest and most thorough cleaning speed.
5. Beginning at the top of the vessel, proceed to clean row by row, marking each row as it is
cleaned.
