• Be sure that you have good balance, do
not have to overreach, and cannot fall
on machine, drain, etc.
• You must be able to reach the REV/O-
OFF/FOR switch.
This operating position will help to main-
tain control of the cable assembly and
FlexShaft Machine.
Figure 10 – In Operating Position
4. Confirm that at least 1' (0.3 m) of cable
assembly is in the drain.
5. Grasp the exposed cable assembly with
both gloved hands equally spaced and
pull 6"-12" (150mm - 300mm) of cable
out of the drum so that there is a slight
bow in the cable. Gloved hands must be
on the cable to control and support the
cable. Improper cable support can allow
the cable to kink or twist and can damage
the cable or injure the operator. Make sure
that the cable outlet of the drain cleaner
is within 4' (1.2 m) of the drain opening
(Figure 10).
6. Move the REV/O-OFF/FOR switch to
FOR (Forward) position.
7. Depress the foot switch to start the ma-
chine. There will be a slight delay be-
fore the cable starts to rotate. The person
controlling the cable must also control
the foot switch. Do not operate the drain
cleaner with one person controlling the
cable and another person controlling the
foot switch. This can lead to twisting, kink-
ing and breaking of the cable.
8. The FlexShaft Drain Cleaning Machine uti-
lizes high rotational speed and low torque
to clean drains. FlexShaft cable assem-
blies are more flexible than other types
of drain cleaning cables. The FlexShaft
machine is best used by applying light
pressure and slowly working the chain
knocker into the blockage. It’s important
to let the speed of the chain knocker
clean the drain – do not force chain
knockers into blockages.
9. Advancing/Retrieving the Cable
Assembly – FlexShaft Lubricant
In some cases it may be beneficial to
apply RIDGID FlexShaft lubricant to the
outside of the sheath when feeding the
cable down the drain. This can make it
easier to advance the cable assembly
down the drain and allow greater clean-
ing distance. If doing so, place a clean
towel with lubricant on it in the palm of the
gloved hand used for advancing the cable
assembly, and apply lubricant as feed-
ing the cable assembly (Figure 11). Add
lubricant to the towel as needed during
the process. RIDGID FlexShaft markings
are printed on the sheath every 5' (1.5 m)
to aid in determining how much cable
assembly has been fed from the machine.
Only use RIDGID FlexShaft lubricant.
Other lubricants may not be appropriate
for use in a drain and could contaminate
the water.
When retrieving the cable assembly, it is
good practice to use a towel to wipe dirt
and debris from the cable sheath as it is
pulled from the drain and fed back into
the drum.
10. Rotating the Chain Knocker
Generally the chain knocker is rotated for
cleaning while withdrawing the cable.
Only rotate the cable/chain knocker when
the chain knocker is at least 1' in the
drain. To rotate the cable, firmly grip the
cable and depress the foot switch. The
person controlling the cable assembly
must also control the foot switch. Do not
operate the machine with one person
controlling the cable assembly and an-
other person controlling the foot switch.
Do not allow cable assembly to build up
outside the drain, bow or curve. This can
lead to twisting, kinking and breaking of
the cable. At any time, release the foot
switch to stop cable rotation. When clear-
ing blockages, operate the cable at full
speed for best cleaning. Do not force the
chain knocker into blockages. Rotating
the chain knocker in FORWARD or RE-
