9. Tilt the machine forward and use your foot to rotate
one kickstand at a time to the backside of the wheel.
The machine should firmly rest on the kickstands.
The kickstands stabilize the machine and help prevent
tipping or walking during use. If working on soft ground,
it may be necessary to place wood or other solid ma-
terial under the drain cleaner for proper support.

10. Evaluate the work area and determine if any barriers
are needed to keep bystanders away from the drain
cleaner and work area. The drain cleaning process can
be messy and bystanders can distract the operator.
11. Select proper tool for the conditions.
If the nature of the obstruction is unknown, it is good
practice to use a straight or bulb auger to explore the
obstruction and retrieve a piece of the obstruction for
inspection.
Once the nature of the obstruction is known, an ap-
propriate tool can be selected for the application. A
good rule of thumb is to start by running the smallest
available tool through the blockage to allow the backed
up water to start flowing and carry away the debris and
cuttings as the drain is cleaned. Once the drain is
open and flowing, other tools appropriate for the block-
age can be used. Generally, the largest tool used
should be no bigger than the inside diameter of the
drain minus one inch.
Proper tool selection depends on the specific circum-
stances of each job and is left to the users' judgement.
A variety of other cable attachments are available and
are listed in the Accessories section of this manual.
Other information on cable attachments can be found
in the RIDGID Catalog and on line at RIDGID.com or
RIDGID.eu.
12. Securely install tool on the end of the cable (See
Figure 4). If the connection is not secure, the cutting
tool may fall off in use.

13. Position the foot switch for easy accessibility. You
must be able to hold and control the cable, control the
foot switch, and reach the FOR/OFF/REV switch.
14. Confirm that the FOR/OFF/REV switch is in the OFF
position.
15. Run the cord along the clear path. With dry hands
plug the drain cleaner into a properly grounded outlet.
Keep all connections dry and off the ground. If the
power cord is not long enough, use an extension
cord that:
• Is in good condition.
• Has a three prong plug similar to that supplied on
the drain cleaner.
• Is rated for outdoor use and contains a W or W-A in
the cord designation (i.e. SOW), or complies with
H05VV-F, H05RN-F types or IEC type design
(60227 IEC 53, 60245 IEC 57).
• Has sufficient wire size (16 AWG (1.5mm
(15.2m) or less, 14 AWG (2.5mm
(15.2m – 30.5m) long). Undersized wires can over-
heat, melting the insulation or causing a fire or
other damage.
When using an extension cord, the GFCI on the
drain cleaner does not protect the extension cord. If
the outlet is not GFCI protected, it is advisable to use
a plug in type GFCI between the outlet and the ex-
tension cord to reduce the risk of shock if there is a
fault in the extension cord.
