7. Take the drain cleaning machine to the work area
along the clear path. If the machine needs to be
lifted, use proper lifting techniques. Use care moving
equipment up and down stairs, and be aware of pos-
sible slip hazards. Wear appropriate footwear to help
prevent slips.
8. Position the drain cleaning machine so that the K-750
cable outlet is within 3 feet of the drain access. Great -
er distances from the drain access increases the
risk of the cable twisting or kinking. If the machine
cannot be placed with the cable outlet within 3' of the
drain access, extend the drain access back to within
3' of the cable outlet with similar sized pipe and fit-
tings. Improper cable support can allow the cable to
kink and twist and can damage the cable or injure the
operator. See Figure 10. If using front guide hose,
place machine so that at least 6" of guide hose can be
placed in drain opening.

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 blockage
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 cir-
cumstances 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
