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 12, 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, the
electronic torque limiter will shut off the
motor to reduce the likelihood of cable
damage. The torque limiter LED will flash
to indicate this. Release the foot switch to
allow motor to restart. Place the REV/O-
OFF/FOR switch to allow opposite ro-
tation. 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. Repeat if necessary.
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.
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 12, 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.
Using Machine With Brushes
Using the machine with a brush is similar to
use with a chain knocker. Brushes are used
for finer cleaning of the pipe, they are not
used for blockage removal. Remove block-
ages and heavy debris with a chain knocker
or other methods first. While chain knockers
are most typically rotated while withdrawing
the cable from the drain, brushes are typi-
cally used while advancing the cable. This
is because the brushes typically fill the drain
diameter and push debris in front of them.
See Figure 13 for general steps.
Brushes can also be used in conjunction with
chain knockers such as centering devices
or for combined cleaning. Usage depends
on the exact circumstances and is left to the
judgment of the user.
NOTICE
1
1. Advance the brush (generally not rotating)
into the drain.
2. When the area to be cleaned is reached, if
possible, start a flow of water through the
drain to carry debris away during cleaning.
3. Rotate the cable/brush at full speed and
gradually advance the cable into the drain
to clean the walls as desired.
