inspection of the drain with a camera is 

a good practice. Crossbores, improperly 

placed utilities and damaged drains could 

allow the chain knocker to contact and 

damage the utility. This could cause elec-

trical shock, gas leaks, fire, explosion or 

other serious damage or injury.

Read and understand these instruc-

tions and the instructions and warn-

ings for all equipment and materials

being used before operating this tool

to reduce the risk of serious personal

injury.

Description

The RIDGID

®

 Model K9-306 FlexShaft™ 

Drain Cleaning Machine is designed to clean 

and descale 3" to 6" (75-150 mm) pipes and 

drain lines, up to 125' (38 m) in length.

A REV/O-OFF/FOR switch controls cable rota-

tion and a pneumatic foot switch provides ON/

OFF control of the motor. An integral Ground 

Fault Circuit Interrupter (GFCI) is built into the 

line cord.

The cable assembly is manually fed in and 

out of the drain and rotates at 2000 RPM. A 

chain knocker that expands to the pipe inside 

diameter is used to break up the blockage and 

clean the walls of the pipe. Chain knockers 

with carbide cutting tips are available for use 

on roots and cleaning the scale from the pipe 

wall. Plain chain knockers are for general use, 

including grease. 

FlexShaft Drain Cleaners are well suited to 

use with inspection cameras during the drain 

cleaning process. 

It is not recommended to clean glass, ceramic, 

porcelain or similar fixtures with the FlexShaft 

Drain Cleaners as it may damage the fixture.
