OPERATION
Correct Machine Position and Operation is critical to getting the job done quickly and efficiently.
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 flexshaft 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 flexshaft
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 floor.
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
flushes away deposits cleaned from the tube and helps to lubricate and cool the flexshaft.
Position the “O” ring in the recess of the flexshaft 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.
