does not. Many times this is accompanied
by vibration/noise from the drill. When using
the K9-12 FlexShaft Drain Cleaning Machine,
always start with the drill adjustable clutch
set to approximately 25% of the total clutch
adjustment range (example – if the torque
adjustment collar on the drill is marked from 1
to 20, the initial setting should be 5).
Battery powered drills are often also equipped
with "Drill" ( ) and "Hammer" (
of operation (Figure 8). In these modes, the
adjustable clutch does not work, and these
modes should never be used for FlexShaft
Drain Cleaning Machine operation.
Operate the drain cleaner per these instruc-
tions with the chain knocker in a drain. The
K9-12 FlexShaft machine integral clutch
should release first before the drill clutch
releases. If during operation the drill clutch
continuously releases ("clutches out"), before
the integral K9-12 FlexShaft Drain Cleaning
Machine clutch, then the drill clutch must be
adjusted. Release the drill switch and remove
the drill from machine. The drill adjustable
clutch setting should be increased. The drill
clutch can be increased in steps until the drill
runs smoothly and no longer releases before
the K9-12 FlexShaft machine integral clutch.
If the integral FlexShaft machine clutch contin-
uously releases, withdraw the cable from the
drain. Review the drain cleaner set up and op-
eration and confirm everything is correct – an
important part of the set up for proper opera-
tion is chain knocker selection and adjustment
(See Figures 10 & 11). Make any needed
changes and continue cleaning drain. If the
integral K9-12 Machine Clutch continues to
disengage during use, consider using another
RIDGID drain cleaning machine.

1. Select proper chain knocker for the con-
ditions.
Chain knockers are sized based on collar
inside diameter and are designed for spe-
cific cable sizes. ¼" chain knockers are
used on ¼" cable, etc. Do not use a larger
size chain knocker on a smaller cable (for
instance / " on ¼"). See Figure 9 and

Chain knockers without carbide cutting
tips can be used in common pipe types.
These chain knockers work well in
grease and similar blockages.

K9-12 FlexShaft
Chain knockers with carbide cutting tips
are used for removing scale from the in-
side of the pipe and can be used for scale
and roots. Carbide cutting tips are used
for aggressive cleaning and could dam-
age pipe, especially softer materials (such
as plastics and Orangeburg), thin walled
pipe, or if the chain knocker is kept in one
position for an extended time. See Figure
