OPERATION (CONT.)
The machine is now ready to operate.
Hold the end of the flexshaft with your hand about 12” (304.8mm) back from the cleaning device.
Insert the cleaning device just inside the tube to be cleaned and hold the flexshaft away from your
body. Depress the foot switch and start to feed the flexshaft down the tube.
It is important that the flexshaft not be forced down the tube. If you meet resistance, proceed at a
slower pace or refit the flexshaft with a smaller cleaning device. Should the flexshaft meet too much
resistance it will begin to coil.
WARNING
This machine drives high speed, rotating cleaning devices. It is recommended
that the operator wear safety glasses with side shields or full face shield eye
protection, gloves and water repellant, nonskid foot wear. Avoid contact with
objects other than the tube when the machine is in operation.
WARNING
DO NOT ALLOW THE FLEXSHAFT TO COIL. Coiling of the flexshaft could
cause binding within the casing and shear the core material. If a blockage
is encountered, and the shafting begins to coil, immediately stop feeding the
shafting into the tube and start drawing the shafting back until coiling stops.
Then proceed to slowly feed the flexshafting into the tube, being sure to draw
the shafting back when blockage is encountered and coiling begins. Follow
this procedure until the cleaning device removes the blockage.
WARNING
DO NOT FORCE FLEXSHAFT THROUGH A TUBE BLOCKAGE. If an
obstruction is discovered or in case of high deposit build-up, reduce the rate
of feed on the flexshaft and allow cleaning device additional time to clear the
blockage. Applying more torque to attempt to break through heavy deposits
could result in damage to the flexshaft.
