Flexshaft breakage near the machine.
• Radius of flexshaft is too sharp. Position machine horizontally and at right angle to the tubes
being cleaned. (See “Operation” section)
• Flexshaft is too short for the length of tube being cleaned causing too sharp a radius for
proper operation of the flexshaft. Call Elliott to obtain the proper length
Flexshaft breakage near the cleaning device.
• Flexshaft is allowed to exit the far end of the tube being cleaned causing “Whipping” of the
flexshaft. Measure and mark flexshaft casing with tape to prevent “over-travel” of flexshafting
when cleaning. (See “Operation” section)
• Flexshaft is being forced through a tube blockage. Reduce the rate of feed on the flexshaft
and allow cleaning device additional time to clear the blockage. (See “Operation” section)
Flexshaft coils up when cleaning device is inserted into the tube.
• Check the internal diameter of the tube (Elliott Tube Gauge is recommended) past the expand-
ed portion at the tube opening. Verify the working diameter of the cleaning device being used.
• Reduce the feed rate of the flexshaft and allow more time for the cleaning device to remove
deposits.
• Check for internal enhanced (rifled) surface under the deposit layer. Some cleaning devices
are not designed to clean this type of surface.
• Check for sharp bends or pinch points in the flexshaft.
• Check for proper water flow through the flexshaft. (See “Operation” section)
How to repair broken flexshafts.
• See pages 22 & 23 for use of W900-00.
