K-750R Drain Cleaning Machine
Machine and Work Area Set-Up
WARNING
Set up the drain cleaning machine and work area ac-
cording to these procedures to reduce the risk of in-
jury from electric shock, twisted or broken cables,
chemical burns, infections and other causes, and
prevent drain cleaner damage.
Always wear safety glasses, RIDGID drain cleaning
gloves, and other appropriate protective equipment
when setting up your drain cleaner.
1. Check work area for:
• Adequate lighting.
• Flammable liquids, vapors or dust that may ignite. If
present, do not work in area until sources have
been identified and corrected. The drain cleaner
is not explosion proof and can cause sparks.
• Clear, level, stable dry place for machine and oper-
ator. Do not use the machine while standing in wa -
ter. If needed, remove the water from the work area.
Wood or other coverings may need to be put down.
• Properly grounded electrical outlet. A three-prong or
GFCI outlet may not be properly grounded. If in
doubt, have outlet inspected by a licensed electrician.
• Clear path to electrical outlet that does not contain
any potential sources of damage for the power cord.
2. Inspect the drain to be cleaned. If possible, determine the
access point(s) to the drain, the size(s) and length(s) of
the drain, distance to mainlines, the nature of the block-
age, presence of drain cleaning chemicals or other
chemicals, etc. If chemicals are present in the drain, it is
important to understand the specific safety measures re-
quired to work around those chemicals. Contact the
chemical manufacturer for required information.
If needed, remove fixture (water closet, etc) to allow ac-
cess to the drain. Do not feed the cable through a fixture.
This could damage the drain cleaner and the fixture.
3. Determine the correct drain cleaning equipment for the
application.
Drain cleaners for other applications can be found by
con sulting the RIDGID Catalog, on line at RIDGID.com
4. Make sure machine has been properly inspected.
5. If needed, place protective covers in the work area.
The drain cleaning process can be messy.

6. Position the drain cleaning machine so that the K-750R
cable outlet is within 3' (0.9 m) of the drain access.
Greater 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'
(0.9 m) 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 op-
erator. (See Figure 7.)
Figure 7 – Example Of Extending Drain To Within 3' of
Cable Outlet
7. 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 tip-
ping 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.

8. 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.
