VERSE for a short time while advancing
the cable assembly can help it negotiate
the drain and blockages.

Sheath
11. Advance the cable assembly into the
drain, generally not rotating. Grasp the
sheath near where it exits the machine
housing. Pull 6" to 12" (150 to 300 mm)
of cable assembly out of the FlexShaft
Machine so that there is a slight bow in
the cable. Gloved hand must be on cable
assembly to control and support. Improper
cable support can allow the cable as-
sembly to kink or twist and can damage
the cable or injure the operator. Feed the
cable assembly into the drain (Figure 12,
Step 1).
12. Continue to advance the cable assem-
bly until the resistance is encountered.
Carefully work the chain knocker through
the blockage. Do not force the cable as-
sembly – if the chain knocker cannot
turn, it cannot clean the drain. Pay at-
tention to how far the cable has gone. Do
not overrun the cable into a larger drain.
This can cause the cable to knot up or
cause other damage (Figure 12, Step 2).
13. Once the drain is open, if possible, start a
flow of water down the drain to flush the
debris out of the line and help clean the
cable assembly as it is retrieved. This can
be done by turning on a faucet in the sys-
tem or other methods. Pay attention to the
water level, as the drain could plug again
(Figure 12, Step 3).

age/area to be cleaned and REV/O-OFF/

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 knock-
er 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.
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.
