FlexShaft™ Drain Cleaning Machine
FOR switch in FOR position, depress the
foot switch to rotate the chain knocker.
Slowly pull the cable assembly from the
drain, allowing the rotating chain knocker
to clean the drain walls and break up the
blockage (Figure 10, Steps 4 & 5). If the
cable stops turning, do not continue
operating the machine. This may cause
the cable to twist and kink. At any time, re-
lease the foot switch to stop cable rotation.
Rotating the cable in REVERSE can help
clean the opposite side of the pipe.
Monitor the feedback from the feel of the
cable assembly in your hand and the
sound of the motor/knocker in the drain.
It may be necessary to move the chain
knocker out of the blockage to allow it to
come back up to speed.
If the chain knocker becomes stuck, place
the REV/O-OFF/FOR switch to allow op-
posite rotation. Grasp the cable with both
gloved hands, press the foot switch for
several seconds and pull on the cable until
it is free of the blockage. In some cases, it
may be possible to pull the cable assembly
and the blockage out of the drain by hand.
If this is done, be careful to not damage
the cable assembly.
The general operating steps for the FlexShaft Drain Cleaning Machines (see below):

1. Advance the chain knocker (generally not
rotating) to the area of the drain that needs
cleaned.
2. If there is a blockage, pass the chain
knocker through the blockage.
3. If possible, start a flow of water through the
drain to carry cuttings and debris away as
the drain is cleaned.

Place the REV/O-OFF/FOR switch in the
FOR position and continue cleaning the
drain.
Do not allow the spinning chain

knocker to hit the camera head/push rod.
It can damage it.
15. Continue to clean the rest of the drain
while retrieving the cable. Once the drain
has been cleaned, retrieve the cable and
feed back onto the drain cleaning ma-
chine. Pay close attention, as the cable
may lodge in a blockage while being re-
tracted (Figure 10, Step 6).
16. Watch for your sheath marking as the
cable assembly is retrieved. Release
the foot switch when the chain knocker
nears drain opening. Do not pull the chain
knocker from drain while it is rotating. The
chain knocker can whip around and could
cause serious injury.
17 . If needed for complete cleaning, repeat
the above procedure.
18. Pull any remaining cable assembly from
the line by hand and push back into the
drum. Prepare the machine for transport.

4. Rotate the cable/chain knocker at full speed.
5. Continue to rotate knocker. Gradually with-
draw the cable assembly so that the chain
knocker can break up the blockage.
6. Continue to gradually withdraw the cable
assembly while rotating so that the chain
knocker can clean the walls of the drain.
